Chrysopilus connexus Johnson 1912

Chrysopilus connexus Johnson
1912. Chrysopilus connexus Johnson, Psyche, xix, p. 108.
Wholly velvety black, except extreme base of halteres which is pale brownish, and the tibiae wholly and the two or three basal tarsal segments which are yellowish; abdomen with two rows of tufts of silvery white hairs on posterior margins of segments one to five which are somewhat more conspicuous in the female than in the male; wings smoky brown, the veins bordered with darker brown as in thoracicus Fab. Length, male 11 to 12 mm., female 12 to 12.5 mm.
This species belongs to the velutinous group of Chrysopilus which is composed of thoracicus Fab., davisi Johns, and velutinus Loew. It comes close to the last. When the abdomen of connexus is badly rubbed it is sometimes difficult to distinguish it from velutinus. I believe however that in the better preserved specimens the longer hairs on the mesonotum and scutellum will usually serve to aid in separating this species from velutinus.
Holotype. — Male; Black Mountains, North Carolina, [U. S. N. M., No. 15450].
Allotype. — Female; as above.
Paratype. — Female; as above, [C. W. Johnson Collection].
Specimens Examined: 30; 10 males, 20 females.
North Carolina: i 9 ■ Linville Falls, 4000ft., (F. Sherman), mid-June, 1920; 1 d 1 9 in coitu, 1 9, and 1 c? early June 1920, [all N. Car. Dept. Agr.]. 1 d 2 9, Hot Springs, (A. T. Slosson), [A. M. N. H., ex Slosson; determined by Coquillett as velutinus]. 1 9, Junatuska Mountain, Haywood County, June 18, 1920, (W 7 m. T. Davis), [Davis]. 4 d 6 9, Black Mountains, [A. M. N. H.; three of the males are badly rubbed and may be velutinus]; 1 d 4 9 , [U. S. N. M.]; also the holotype, allotype and paratype.
Florida: 2 <?, 2 9, Jacksonville, [A. S. N. M.; determined by Coquillett as velutinus]; 2 9, [U. S. N. M.]. As C. W. Johnson (1912: 109), has pointed out the specimen figured by Howard in "The Insect Book," (1905: pi. 16, fig. 23) is connexus, not velutinus. This specimen is a female in the United States National Museum Collection. The two males from Raleigh, North Carolina, each have long erect yellowish hairs along the lateral border of the abdomen and moderately long, dense fine, blackish hairs on the mesonotum ; on the scutellum these hairs are present also but longer and on one specimen are almost yellowish in certain lights; the females with hardly noticeable hairs on either thorax or abdomen.

Chrysopilus connexus is a species of snipe fly in the family Rhagionidae.
