rior margin and one in pterostigma; an indistinct pseudovein 
connecting radius and media, as in Carsidara. 
Abdomen large. Male anal valve a little longer than forceps, 
broadest at middle ; forceps somewhat fusiform, thick at middle, 
apically tapering to a narrow and truncate end. Female genital 
segment large; dorsal valve very large, with a small, curved, 
acute epiphysis caudad, and a large anal opening dorsad; the 
lower margin densely fringed with slender hairs, as a brush. 
Ventral valve very small and retracted more or less completely 
into preceding abdominal sclerite with an acute epiphysis at 
apex. Ovipositor large, very broadly truncate at apex, appa- 
rently permanently exserted, margin fluted.

The Larat specimens very closely resemble those from the 
Philippines except in some very minor color characters and the 
following two wing characters: Forewing of Larat specimens 
a little less acute at apex, and radius shorter; in Philippine 
specimens the radius joins the margin at a point as far from 
tip of pterostigma as the length of latter; in Larat specimens 
the length of pterostigma is nearly twice the length from tip 
of radius to tip of pterostigma. This probably indicates the 
incipiency of another species. 
Genus TYORA Walker 
This genus is very close to Carsidara, differing chiefly in the 
absence of pterostigma in the forewing. Froggatt’s Tyora ster- 
culiss, however, does possess the pterostigma. I am inclined to 
believe that Tyora should be merged with Carsidara, but until 
more material is available for comparison I am unwilling to 
make this change. Tyora indica, described below, is evidently 
very closely related to T. hibisci Froggatt but has no claw nor 
spine at apex of hind femora said to be present in both the 
Australian species of this genus. 
Mesohomotoma Kuwayama is apparently very close to Tyora, 
differing in no essential character whatever, so far as I can 
discover, from Kuwayama’s description. However, until I have 
examined a representative of the Japanese genus, I am loath to 
make any alteration.
