rior margin and one in pterostigma ; an indistinct pseudovein 

 connecting radius and media, as in Canddara. 



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.

 Tayabas Province, Malinao (Baker), 2 females. Tenimber Is- 

 lands, Larat (Muir) , December, 1917, 5 males and 13 females. 



Type locality. — Luzon, Laguna Province, Los Bafios. 



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- 

 culise, 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.
