Scutellum unspined, with microscopic yellow hairs. 
Abdomen.—Dull black, barely shining, the sides with very 
short yellow hairs. Belly similar with very minute yellow hairs. 
Genitalia consisting of a pair of blackish, fairly thick claspers, 
each with a small narrow appendage; there being also an upper 
pair of yellow, hairy, finger-like appendages. 
Legs.—Black, the knees distinctly but not broadly yellowish 
brown; pulvilli pale yellowish.

me at Darjiling (7,000 feet), 29-v-10, on the hillside. 
N.b.—When first describing this species I considered it as 
representing a new genus differing from Bevis only in having an 
unspined scutellum. A closer investigation of existing genera 
revealed its close affinity to Allognosta, Os. Sac., a genus which, 
curiously enough, does not appear to have ever been properly 
characterized. Its history is as follows: Macquart in 1847 set up 
Metopoma for an Australian species and Loew in 1863 described a 
North American species s¢milis and in 1873 a species vagans from 
Siberia, both of which he placed in Metoponia. Osten Sacken in 
1883 (Berl. Ent. Zeits., xxvii, 297) notes that Loew’s idea of 
Metoponta, Macq., was incorrect, forming this opinion on an exa- 
mination of Macquart’s types in Bigot’s collection and states that 
Loew’s two species were not congeneric with Metoponia. He had 
at the moment no specimens of Metoponia, Lw., for comparison but 
suggested Allognosta as a nom. nov. for Loew’s genus. No proper 
diagnosis or differentiation from any other genus seems to have 
appeared. I possess in my collection both ‘‘ Metoponia vagans, 
Lw.,’’ as actually identified by that author, and several of the 
rather common Allognosta fuscitarsis, Say , from North America, but 
unfortunately they are not available for comparison in this country. 
The present species is therefore retained in AJllognosta, and 
the name Anacanthoberis is suggested if it should prove generically 
distinct. 
Chorisops tibialis, Mg. 
One 2 of this commonly distributed European species occurs 
amongst some diptera sent me for examination by Dr. A. D. 
Imms. ‘There can be no possible doubt of the identity. It is 
from Binsar, Kumaon District, Western Himalayas, 28-v-12, and 
is in perfect condition.

between one-seventh and one-eighth the width of the head, with
