Male.—Eyes contiguous for about two thirds their width above, densely long, white pilose, with a sharply defined vertical black band about one-fifth their width; above, the two bands are confluent. Occiput shining olivaceous, white pilose. Ocellar area with a tuft of ferrugineous pile. Spot above the antennæ bare, shining black. Face shining black, except the tip of the indistinct tubercle, which is opaque; covered, except an indistinct median stripe, and more densely below, with abundant long light yellowish pile; very indistinctly concave below the antenné. Cheeks shining olivaceous, except ati anterior velvety cross-band and an indistinct spot below the lowest margin of the eyes; long yellow pilose. Palpi clavate, testaceous at base, apical half black.

P. Rapæ, the introduced “European cabbage butterfly,” on its westward march across this Continent, was first taken in Nebraska on August 3, 1881. (See Can. Ent., 1882, 39.) In May, 1883, I took one male in Southern California. At that time I did not know its name, but I spread it and placed it in my cabinet as unknown. In a few years an Eastern Entomologist called on me, and at once identified it as P. Rapæ. It was yet other years before I saw another specimen in flight, though collecting diligently every season. About 1890 or '91 other specimens were observed, and thereafter every year brought them in rapidly increasing numbers, till now they are extremely abundant, flying early and late in the day, and early and late in the spring and fall, and at times, as in cold or cloudy weather, when only a very few of the native species can fly, indicating that it is more hardy than the native species, and that it will eventually dominate. As might be expected, the larvæ feed in good part on cabbage plants, but yet they are not at all dainty or particular as to food, and many other plants are used. Last year I raised some fine specimens from eggs laid on leaves of common nasturtiums, in the garden, and wholly fed upon those leaves.

In the March number of the Can. Ent., pp. 81–82, Mr. Tutt falls back upon the writings of Dr. Chapman to support his position for this genus as among the Liparidæ. As Mr. Tutt has thus gracefully retired from the discussion without making a direct answer to my facts, I can only, in reply, briefly notice Dr. Chapman's position.

Any time before the middle of June, entomological studies in the mountains are apt to be interrupted by snowfalls; but from that time to September, one will seldom find a better or more interesting place for study. The climate is delightful, and though the common opinion is that no rain falls upon the great plateau, here as elsewhere, suppositions are not facts.

Male.—Length, 10.5 mm. Black with yellowish markings. Head transverse, as wide as thorax, about twice as wide as long when viewed from above; face above the antennæ, and vertex, polished, impunctate, without apparent sutures and with sparse blackish pubescence; the cheeks and under surface with pubescence more dense; clypeus polished; palpi slender; antennæ as long as head and thorax, rather stout, eighteen-jointed, segments subequal; eyes small but prominent; ocelli small, in a triangle on a line with the posterior margins of the eyes. Thorax rugose with coarse, irregular punctures, those of the pleura and pectus smaller and more numerous; posterior angles of prothorax yellow; legs rather slender, coxa and femora black, remainder yellow, the tips of tibiæ and tarsi somewhat dusky; wings subhyaline, with dark stain covering marginal cell and extending slightly beyond each end of it, stigma and costal nervures black, remaining nervures reddish, second and third submarginal cells subequal; scutellunl abruptly rounded posteriorly, postscutellum yellow, prominent, subpyramidal, notched at apex, in suture on each side several deep shining foveæ; metathorax very short and rounded at sides, without prominent angles, a small yellow spot on each side. Abdomen polished, impunctate, apparently with six segments; second segment as long as all the following and with a yellow central band, or elongated spot on each side; a yellowish spot at lateral base of segments 3 and 4, very faint on the latter; venter slightly pubescent, with double row of yellow spots on segments 1 to 5, largest on 2nd.

In former years I had found this beetle, the largest and most conspicuous weevil of our fauna, to occur only upon beeches, as noted in my sketch of the Rhyncophora, in Eleventh Annual Report. Such, also, was Mr. Chittenden's record [Ent Am., Vol. VI., 168]. Its infestation of the twigs of oak had been recorded by Riley, who described the larva. Its occurrence upon hickory is noted by Mr. Beutenmuller [Can. Ent., XXII., 201], and it is known as injurious to apple and other fruit trees. On June 9th. 1895, I observed a pair in coitu upon the trunk of a hickory (Carya amara), where there were no beech trees near by, and on carefully examining other hickories in the immediate vicinity I found five more pairs.

With the exception of some undetermined gallflies and parasites, the following list of 86 species contains all the Hymenoptera collected (and bred) by the author, in the South-west, of which it has proved possible to get the names, except four mentioned in Can. Ent., 1892, p. 200. The gallflies and parasites above referred to will be recorded in some papers to be published in the future. The cottonwood, Blennocampa, mentioned in Can. Ent., 1893, P. 304, and in Zoe, iii., pp. 234–236, should also be included in the above exception.
