TELOTHYRIA. 175 
cross-vein on the middle of the discal cell ; curvature of the fourth vein with a blunt angle; apical cross- 
vein nearly straight; posterior cross-vein slightly curved. 
Hab. Mexico, Amula in Guerrero 6000 feet (H. H. Smith). 
Two female specimens. 
In size and general facies this species agrees with 7. pollens; it cannot, however, be 
the other sex of it, owing to the very different coloration of the head, the much less 
defined thoracic stripes, and the more extended black parts of the abdomen. 
12. Telothyria trifurca, sp. n., 2. 
Black; thorax anteriorly grey, with three broad black bands; head and front borders of the abdominal 
segments whitish; palpi rufous. 
Length 4 millim. 
Front as broad as the eyes; frontal band blackish-brown, nearly as broad as the whitish lateral portions; 
frontal bristles on each side in a curved row, descending as far as the end of the second antennal joint ; 
face and cheeks white, with dark reflections, the cheeks rather broad; above the vibrissw# a few other 
bristles. Antenne black; second joint bristly ; third joint stout, four times as long as the second; arista 
thickened to nearly half its length. Proboscis brown; palpi dark rufous. Thorax black, before the 
transverse suture and at the sides with a whitish-grey tomentum, anteriorly with three broad black bands ; 
scutellum black. Abdomen ovate, shining black; second and following segments with whitish front 
borders, which are interrupted by a black dorsal stripe, and with discal and marginal macrochete of 
moderate length. Legs black; middle tibie with some long bristles; hind tibie outwardly with bristles 
of unequal length; foot-claws and pulvilli short. Tegule whitish. Wings with a brownish tint, which 
is more intense towards the costa; small cross-vein nearly on the middle of the discal cell; apical and 
posterior cross-veins straight or very slightly concave.

13. Telothyria rasilis, sp. n., 3. 
Black, pilose; thorax anteriorly grey, with four black stripes; abdominal segments with cinereous front 
borders ; palpi with rufous tips ; wings brownish. 
Length 5°5 millim. 
Front blackish, narrower than the eyes; frontal band inconspicuous ; frontal bristles numerous, descending to 
beneath the second antennal joint; face and cheeks whitish; eyes descending as far as the tip of the 
antenne; vibrisse surmounted by some shorter bristles; beard white. Antenne black; second joint 
bristly ; third joint slender, four times as long as the second; arista thickened to its proximal half. 
Proboscis blackish-brown, its terminal lips with yellow hairs; palpi filiform, blackish, with rufous tips. 
Thorax and scutellum shining black; thoracic dorsum before the transverse suture with some grey

curved.
