390 DIPTERA. 
clothed with yellowish hairs, but without bristles; the fourth and fifth segments sometimes brownish ; 
at the underside of the fifth a pair of small projections. Legs slender, rufous; middle and hind femora 
with black tips; the femora and tibiz have a yellow pilosity, the tibie several black bristles; tarsi 
brownish, the pulvilli brown. Halteres pale rufous. Wings with a brownish-yellow tinge; small cross- 
vein beyond the end of the first vein and beyond the middle of the discal cell; third and fourth veins 
parallel ; posterior cross-vein straight and nearly perpendicular. 
Hab. Mexico, Ciudad in Durango (Forrer), Omilteme 8000 feet, and Sierra de las 
Aguas Escondidas 9500 feet, both in Guerrero (H. Z. Smith). 
Several male specimens. It is possible that these may be referable to Scatophaga 
reses, Gigl.-Tos, which has a cylindrical abdomen and slender legs, and is therefore 
likely to be a Cordylura. 
3. Cordylura vicina, sp.n., ¢ @. 
Rufous ; occiput with a black spot; thoracic dorsum brownish ; abdomen and legs densely haired (in ¢); 
abdominal segments with black incisions; tips of the middle and hind femora black; antenne elongate ; 
scutellum with four bristles. 
Length 4°5-5 millim. 
Agrees in most of its characters with the preceding (C. rujina), but differs in its smaller size and in the 
brown coloration of the thoracic dorsum. The black spot on the occiput is more conspicuous and trifid 
towards the vertex. In the females the body and legs are less hairy, the tip of the abdomen is pointed, 
and the black incisions on the segments are more distinct. 
Hab. Mexico, Omilteme and Sierra de las Aguas Escondidas (H. H. Smith). 
Several specimens, including three females. 
This insect is perhaps a variety of C. rufina. 
SCATOPHAGA. 
Scatophaga, Meigen, Illig. Magaz. ii. p. 277 (1808). 
A single species of this well-known genus is represented in the Mexican collections 
before me. It agrees in coloration and structure with the Kuropean forms, but 
cannot be identified from any of the published descriptions. 
1. Scatophaga vittata, sp.n., ¢ 9. 
Cinereous ; antenne, palpi, and legs rufous ; femora with a black stripe ; cross-veins slightly infuscated. 
Length 6 millim. 
Front broader than the eyes; frontal band testaceous or rufous, bifid behind ; face pale yellow ; oral margin 
with a pair of vibrissee and some other bristles. Antenne rufous; third joint nearly three times as long 
as the second; arista black, its proximal half thicker and short-haired. Proboscis shining black ; palpi 
pale rufous, slender, the tip with black hairs. Thorax, scutellum, and abdomen cinereous; the thorax 
with indistinct stripes and strong bristles; scutellum with four bristles ; metanotum grey. Abdomen 
elliptical, densely clothed with yellowish hairs in the male. Legs rufous; fore and middle cox cine- 
reous, hind coxe grey; all the femora on the upperside with a black stripe, which does not reach the 
base nor the tip; femora and tibie with yellow hairs (¢), the tibie also with strong black bristles and 
spurs. Halteres yellowish. Wings greyish-hyaline, yellowish at the base and along the costa; cross- 
veins slightly infuscated ; small cross-vein beyond the end of the first vein and beyond the middle of the 
discal cell; posterior cross-vein straight, slightly oblique. In the female the abdomen and legs are less 
hairy.
