Chrysopilus proximus (Walker 1848)

Chrysopilus proximus Walker (PI. Ill, fig. 28)
Leptis proximo, Walker, List Dipt. Brit. Mus., I, p. 214. Leptis simillima Walker, List Dipt. Brit. Mus., 1, p. 215. Leptis propinqua Walker, List Dipt. Brit. Mus., 1, p. 215. 904. Chrysopila proximo, Adams, Kans. Univ. Sci. Bui., 11, p. 436. 904. Chrysopila propinqua Adams, Kans. Univ. Sci. Bui., 11, p. 437. 908. Chrysopilus propinquus Kertesz, Cat. Dipt., in, p. 325.
Chrysopilus proximus Kertesz, Cat. Dipt., in, p. 325. 908. Chrysopilus simillimus Kertesz, Cat. Dipt., Ill, p. 326. Male. — 6.5 to 7 mm. Opaque black, first antennal segment, palpi, sides of face, and body in general with rather numerous erect fairly long black hairs; mesonotum and abdomen with similar hairs and, in the better preserved specimens, with more or less appressed, rather long, dirty white to yellowish or golden tomentum; femora blackish, except tip, which with tibiae and tarsi is brownish yellow; wings almost hyaline, stigma yellowish, diffused, indistinct.
Female. — Length, 6.5 to 10 mm. More brownish; not nearly so hairy, with the hairs shorter and at least in certain lights dirty whitish to yellowish ; the mesonotum somewhat, and the abdomen often thickly clothed with dirty whitish to yellowish appressed rather long hairs.
I have seen a large series of specimens referrable to either propinquus or proximus and believe that I am correct in the synonomy as cited. A rather hasty examination of Walker's types several years ago has led me to this conclusion as also to the conclusion that his simillimus is synonymous with both, certainly at least with propinquus. Students of the group, have in the past attempted to keep proximus and propinquus separate, but according to my present judgement they should be combined. Specimens Examined: About 281 males and females.
