Trichromia is not a Lithosian, as placed in Kirby’s catalogue, as 
ocelli are present. The neuration of the species here described is as 
follows: 
Primaries with 4-branched median, cross-vein of cell strongly angulated, form¬ 
ing a right angle, 6 from the apex, 7-10 stalked, 10 given off before 7, 11 close to 
apex of cell, 12 from base. Secondaries with two internal veins, median 3-branched, 
veins 3 and 4 on a long stalk, 5 absent, cross vein angled, 6 and 7 on a long stalk, 8 
joining the subcostal for only about one-third of the cell, curving and rather remote 
from 7, strong. Tibial spurs normal, small. The ocellus is pale, situated in a black 
ring which is about as wide as the diameter of the ocellus itself and does not touch the 
eye. 
Pygarctia muricolor, sp. nov. 
Fore wing mouse gray with a slight bronzy reflection, translucent except along 
the margins and apically ; hind wing translucent grayish, darker along the outer 
margin, pale at the anal angle. Head dark gray in front, vertex ochre yellow ; collar 
mouse gray, narrowly edged with ochre behind ; thorax gray, the edges of the pata- 
gia a shade lighter; below ocherous, including coxae ; legs gray. Abdomen buff, a 
dorsal row of small dots and a rather broad lateral band mouse gray. Expanse, 41 
mm.

To give a wider comparison with southern forms this species may be 
provisionally placed in the genus Opharus Walk, on superficial resem¬ 
blance. The following are its structural characters : 
Accesory cell present, veins 7-10 from its apex, 8 and 9 stalked ; 8 of secondaries 
joining cell for half its length, faint at the tip ; no veins absent. Palpi oblique, por- 
rect, not reaching the vertex, first and second joints subequal, third half of the sec¬ 
ond ; tibial spurs normal, short. Body slender ; antennae long ; hind wings rather 
large. 
Assuming the described species of Opharus to be congeneric, they 
would separate as follows :
