During the past four years the writer has been getting together a collection of Locustidæ from various parts of the State of Indiana, with a view a preparing a general descriptive paper of the species of that family found in the State. In working over the material thus gathered thirty-seven species are found to be represented, four of which are evidently new to science. Of the four, three belong to the genus Orchelimum and one to the genus Conocephalus. The former genus is represented in the collection by ten specis and the latter by four. Below is given a descritption of each of the four species believed to be new, together with such notes concerning the distribution of each as I find in my field note-book.

In the part of Mr. Strecker's Lepidoptera, Indeigenous and Exotic, dated Feb. 22nd, 1875, is the description, and on the accompanying plate on excellent figure, of this species from a female sent to that author by the late Mr. Caulfield, and which was probably taken in the previous summer. The speciment was found in Phillips Square, which is about two miles from its nearest known locality, by the caretaker, from whom it passed to the taxidermist of Natural History Society, who gave it to Mr. Caulfield.

Head prominent, with a high vertical tuft. Front nearly square, rather higher than broad; slightly convex Vertex small, with a low, conical central projection. Ocelli absent. Eyes large, naked, reaching as far as the front and above the vertex. Antennae inserted far apart, close to the margin of the eyes. In $$ lengthily bipectinate, the pectinations diminishing gradually, the distal third being bare. To judge from the fragments of a $$ specimen with broken off antennæ (only 6 joints left to judge from), the $$ antennae are apparently simple. Palpi exceeding front by two thirds their length; second joint very large, third small. Tongue weak, but moderately long, coiled. Thorax robust, about as broad as long.

Myzine Thoracica.

♀.—Clypeus strongly and closely punctured, carinated or angular down the middle; front with large, coarse punctures, which become sparser on the vertex and cheeks; the ocelli deeply pitted, the hind pair almost hidden; prothorax, mesopleauræ, dorsulum and scutellum with large, separated punctures, those on the dorsulum by far the largest and sparest; metathorax above and behind entirely smooth, the metapleuræ with oblique striations; legs, especially the tibiæ, coarsely punctured, the outer side of the medial and hind tibiæ covered with strong, shor bristles, and in addition with a row of stout, short spines on the outer edge, the medial and hind tarsi with long bristles and spines; anterior tarsi with the spines stout, the longest equalling the length of the first joint of that tarsus; wings flavo-hyaline, somewhat fuscous apically, the nervures testaceous; abdomen wiht a beautiful iridescent sheen dorsally, with fine rather close punctures, the first segment and base of the following three impunctate; on the apical portion of segments 1–3 the punctures are sparse and stronger, those on the fifth segment stronger; ventral segments on apical portion with large punctures or holes, which form on segments 1–4 a transverse row, which is produced or holes, which form on segments 1–4 a transverse row, which is produced foward into an angle medially; last dorsal segment with fine longitudinal striations.

While engaged in the re-arrangement of some boxes of Cerambycidæ recently, the peculiar modifications of the ordinarily very simple pattern of coloration in the genus Crossidus brought about the desire to see to what extent and under what circumstances certain of these modifications were carried on or existent. The results of the studies ensuing thereupon are presented in the present paper.

Coleocentrus canadensis, n. sp.

Female.—Length, 20 mm. Black, with red legs. Head transverse, as wide as thorax; cheeks as wide as eyes; face slightly swollen below antennæ, clothed with short pubescence, and with the inner orbits faintly yellowish below; palpi and inner edges of mandibles and labrum rufous; vertex and cheeks polished, the area of the ocelli without noticeable depressions or sutures; antennæ long and moderately thick, the joints about forty and subsequal. Thorax polished above; the lobes of the mesothorax prominent, the central sulcate; pleuræ and pectus rugose or subaciculate, but without definite striæ; scutellum moderately large and elevated; metathorax with acute carinæ; the area enclosed by the two discal carinæ about twice as long as wide; in the area enclosed by the two lateral carinæ the elongate spiracle may be plainly seen almost in centre; the areas between lateral and discal carinæ transversely rugose; legs slender with robust coxæ, entirely rufous with exception of hinder tibiæ and tarsi, which are somewhat brownish; wings faintly yellowish, stigma and nervures brown, areolet small, triangular and pedicellate, receiving the recurrent nervue at outer angle.

In my last paper (see page 32) I unfortunately repated the erro made by Provancher in giving Vancouver as the habitat of Ecihrus provancheri. I overlooked its correction (Can. Ent., Vol. XVII, page 160) by Mr. Brodie, who obtained the insect from Muskoka.

Having recently restudied and rearranged my Ottawa collections of Phyllphaga and Xylophaga, so as to prepare for publication in the Ottawa Naturalist a complete list of the local species, I have made some notes which may be of more general interest. There are also several species, apparently new, which I prefer to describe here, as I think that all new species should be described (or at least redescribed) in some publication devoted entirely to Entomology, and accessible to all students.

This species has long been lost sight of. It was described nearly sixty years ago from a single male “in good condition”. I never have heard of its forming part of any collection except that of the British Museum, and my own, and my specimens—a male and a female—were sent me from the Museum more than twenty years agp. In his Catalogue fo the Satyridæ, 1868, Mr. Butler says of this species: “We do not pposses the type, but our specimens agree exactly with Mr. Curtis's description.”

Mr. F. M. van der Wulp, the well-known Dutch dipterologist, has recently published, in the Tijdschrift voor Entomologie, vol.35, pp. 183–195, short dignoses of a large number of new species and several new genera of Mexican Tachinidæ sens. lat. Of these, there are 33 new species and 4 new genera which belong to the above four groups. Of such well known and well-worked genera as Trichopoda, there are 4 new species; of Hyalomia, 10 new species; of Cistogaster 8 new species!

1. E. castanea, sp. nov.

♂. The form of the wings is exactly like that of Senegalensis, H. S. Upperside.—The ground colour is rich chestnut-brown, marked by broad black series of spots and bands. Upon the primaries these markings are as follows:-In the cell a longtiudinal basal streak, a transverse line, a figure 8, a twice curved transverse line, and a broad bar at the end of the cell constricted in the middle; below the cell there is a short basal band curving inwardly; beyond the cell there is a wide band running from the costa toward the outer margin as far as the lower radial; and then abruptly turning and extending to the middle of the inner margin; beyond this is a broad band of diffuse spots, wide on the costa, narrower beyond the end of the cell, and gradually widening as it apporaches the inner margin; beyond this is a submarginal series of very black round spots.

The specimens on which the present paper has been based were collected by Mr. Trevor Kincaid, of Olympia, Washington. They were all collected near that city except a few, which were taken along the Skokomish River. Great credit is due Mr. Kincaid for bringing together so large a collection. The specimens are deposited in the entomological collection of Cornell Univerisity.

Phyciodes carlota, Reak.

Larva.—Head subcordate, apices slightly produced, mouth parts small; rough, tuberculate, hairy; colour black, a narrow white line above the mouth. Body robust, with short and thick conical, densely-bristly spines, arranged thus: on joint 2 one short stigmatal and one substigmatal, besides tubercles on the cervical shield; on joints 3–4, subdorsal, lateral and subventral; on 5–11, dorsal (single), suprastigmatal, substigmatal, 2 subventral; on 12, two dorsal (in line), subdorsal, superstigmatal, substigmatal and subventral (small); on joint 13, two subdorsal (in line). Cervical shield, anal plate, feet outwardly and spiracles black; body brownish red, with a dorsal and subdorsal black shaded line, most distinct in the segmental incisures.

Since my last article ont his group Can.Ent., Aug.,1891), I have obtainded quite a number of forms; some of the new ones are described in this article. Two genera, new to the U.S., are recorded, both of which occur in South America. Chelifer alius, described by Leidy in Proc. Phil. Acad. Sci., 1877, agrees, as far as description goes, with Chelanosp oblongus, Say and with no other form known to me, therefore I consider it a synonym of C. oblongus.

Eigth examples bred from larvæ in the Yosemite Valley differ from Mr. Cresson's description in having both wings unifrom smoky blackish, about as dark as the hind wings of Hylotoma scapularis, Klug. In the ♀, the pale parts of the legs are not white, but of an obscure sordid whitish, tinged with brown, and not contrasting with the black body parts; the abdomen is obscurely banded with brwon between the segments.

Mr. Andrew Bolter, of Chicago, has kindly sent me the type of this species for examination. It proves to belong to none of our families of Bombyces, as I had suspected.

Blacodes cristatus, n. sp.,♀

Wholly black, the tibiæ slightly piceous. Head light gray pollinose, that in middle of the front dark brown; face moderately convex, mystax black and white, very dense and extending nearly to the antennæ first joint of antennæ slightly longer than the second; third joint lanceolate, three times as long as the second joint; style slender, slightly over half as long as the third joint. Thorax very convex, gray pollinose and marked with a broad blackish-brown geminate median stripe, which is considerably dilated outwardly behind the middle; on each side of this stirpe is a broad, irregular, blackish-brown stripe extending but little in front of the middle of the dorsum; the median brown stripe bears numerous black and light yellow pile, which, on the anterior portion, forms a nearly erect crest; bristles of thorax black and light yellow; pleura mottled light gray and dark brown pollinose, the pile white; the fan-like row of bristles in front of the halteres is white.

This species is quite common in New Mexico, where it feeds on the native sunflower (Helianthus sp.). On August 7, 1892, at Belen, N. Mex., I found the native Helianthus annuus badly infested with the adults and numerous light green grubs of this species, where were eating the leaves extensively.

In the summer of 1892 I spent a month on the line of the Southern Pacific R. R., between Morgan City, Louisiana, and San Antonio, Texas. While the collectiong was by no means of the best, a few notes may interest the readers of the Canadian Entomologist and give some idea of insect life in the Southern States during the hot months.
