Podisma (Latr.) is a particularly interesting genus of Melanopli, since it is the only one of that immense group that occurs in the Old World, where, indeed, it is represented by considerably more described species than it is in North America. It is also of interest from its distinctly boreal and alpine distribution, being almost peculiar to high latitudes or altitudes. It is a circumpolar genus, inhabiting the mountains and boreal parts of Europe, Asia and North America, a larger number of species having been described from Europe than elsewhere.

Too late for correction, I find that in my recent paper on western Orthoptera* I have redescribed Scudder's Aulocara rufum as a new species under the name guanieri, placing it in the not very nearly related genus Heliastus. This unfortunate mistake was brought about by the uncertain position of the genus Aulocara, which possesses both tryxaline and Œdepodine characters. The generral aspect of the species of the genus is certainly very strongly œdipodinean and the characters of the declivate vertex, subperpendicular front, filiform antennæ, small round eyes, obsolete lateral carinæ, twice or thrice severed median carina, wrinkled pronotum, and of the generally present intercalary vein, all indicate close affinity to the Œdipodinæ.

William E. Leach, and not Frederick Smith, Ernest André has it, was the first to establish the family Mutillidœ but none of these gentlemen correctly defined it, and all have included genera which do not belong to it. Some of the genera belong to the Bethylidœ, one belongs to the Thynnidœ, one to the Cosilidœ, and others to the Myrmosidœ.

Anopheles Barberi, new species.—Near Walkeri, but only about half as large, the upright forked scales of the occiput chiefly yellowishwhite, body devoid of scales, etc. Black, the base of the antennæ, clypeus, stems of halteres, coxæ and trochanters yellow, thorax and scutellum yellowish-brown, front portion of the former and the pleura more yellowish, occiput devoid of appressed scales; thorax somewhat polished, thinly bluish-gray pruinose, the hairs and bristles chiefly black, those of the abdoment mostly yellowish, of the coxæ yellow; femora with a distinct bluish tinge, tarsal claws simple; wings hyaline, the scales brown, the lateral ones lanceolate, petiole of first submarginal cell about one-third as long as that cell, base of the latter much nearer the base of the wing than that of the second posterior cell, hind crossvein less than its length from the small crossvein; length, 3 mm.

A small collection of mosquitoes has been sent me by Dr. Grabham, collected by himself and Mr. T.D.A. Cockerell at Pecos Canon, New Mexico, U.S.A.

This collection was made in June and contains five species, namely:

1. Theobaldia incidens, Thomson.

2. Culex Kelloggii, Theobald.

3. Culex consobrinus, Desvoidy.

4. Grabhamia Curriei, Coquillett.

5. Grabhamia vittata, nov. sp.

It has always been claimed that there is but one brood of Hessian Fly in Minnesota. On June 25th of current year larvæ of Hessian Flyin second stage were found working on wheat in an adjoining county, brought to the Experiment Station and the wheat plant placed in moist sand in breeding jar in laboratory. These specimens quickly formed puparia, and one fly, a female, emerged July 19th. She lived about two days, before dying depositing between 80 and 90 eggs on green blade of wheat and on dried wheat stem in breeding cage. The eggs were laid indiscriminately on leaf and stem, some singly, some in clusters of two or three and some in strings attached by ends.

Dr. Burnside Foster, of St. Paul, a short time since sent me three Dipterous larvæ taken from the cutaneous tissue of a three-weeks-old infant, born on the seventh mont, at Superior, Wisconsin. I at first thought the insect to be Lucilia, but being in doubt, and having no biological collection in this group for reference, I immediately sent it to Washington, receiving a telegramin reply that Mr. Coquillett had identified it as Gastrophilus epilepsalis.
