hairs or bristles, sometimes (H. rujfipes) with a longer bristle in the middle. The wings 
have the black colour less extended and not sharply separated from the hyaline hind- 
border ; or they are broad and have a yellow coloration, interrupted by brownish spots 
or shadows (in the species thus coloured the front is, even in the male sex, distinctly 
. broader than the eyes). 
The name Trichopododes has been proposed for this genus by Mr. Townsend (Canad. 
Ent. 1893, p. 166), on account of Homogenia being too much like Homogenes, Thoms. 
(a genus of Coleoptera) ; but this change is, in my opinion, quite unnecessary. 
The three species known to me may be distinguished as follows :— 
1. Wings shaped as usual in Trichopoda, uniform brown along the 
costa. 2 ew ww we ee ee ee ee we ww Ufipes, Vv. A. Walp.

Homogenia rufipes, v. d. Wulp, Tijdschr. voor Ent. xxxv. p. 184". 
Reddish-yellow ; frontal band, four stripes on the thorax, metanotum, a dorsal stripe and the last segment of 
the abdomen, and the fringe of the hind tibie, black; third antennal joint, apical parts of the femora and 
tibize, and the whole tarsi, dark brown; wings brown on the costal half. 
Length 8 millim. 
Head yellow ; front as broad as the diameter of the eyes; frontal band velvety-black, a black line descending 
from it to the vibrissee on both sides of the cheeks; basal joints of the antenne rufous, the third joint 
dark brown. Thorax with a golden-yellow tomentum and four rather broad black dorsal stripes, which 
are interrupted at the transverse suture; scutellum dark brown, rufous at the hind margin. Abdomen 
somewhat convex, elongate, narrower towards the tip, reddish-yellow, with a brown dorsal stripe, the 
last segments black. Legs rufous; the apical half of the femora and tibiee brown; the fringe of the 
hind tibie black and notably shorter than the breadth of the tibie; tarsi blackish-brown ; foot-claws 
and pulvilli elongate, yellowish, the claws with black tips. Tegule and halteres yellow. Wings with 
the brown coloration limited on its proximal portion by the fourth vein and beyond the small cross-vein 
by the third vein, becoming less distinct near the tip, the remaining portion dilute brownish; the apical 
cell rather broadly opened.

Two males and one female.

Yellowish-rufous ; frontal band, four stripes on the thorax, third antennal joint, a dorsal stripe on the 
abdomen, the tips of the femora and tibiz, the fringe of the hind tibia, and the tarsi, black ; wings broad, 
brownish, their base and costa yellow. .
