440 W. Doberty — Gertain Ljaemdce from Lower Tenasserini. [No. 4, 



more angled in tlie middle, tlie upper median vein of the forewing of the 

 male is not swollen. The prehensors differ but slightly. 



Three males and a female taken in the Tenasserim Valley. Like the 

 preceding species it has a strong irregular flight (quite different from 

 the feeble uncertain motions of the Paragerydi and Loganias), wheeling 

 many times round the same circle, or up and down a certain length of 

 the path, and would be difficult to catch but for its habit of returning 

 again and again to the same leaf. 



104. Geetdus boisduvalii, Moore. 



One female from the Tenasserim Valley, Tavoy district. 



105. GrEBYDUS BIGGSII, Distant. 



One female, Tenasserim Valley. These four species of Qerydus 

 differ somewhat in the length of the cell which increases in the follow- 

 ing order — croton, ancon, hoisduvalii, biggsii. In the first, the end of the 

 cell is immediately beyond the origin of the second subcostal, in the 

 last halfway between those of the second and third, as in Paragerydiis. 



Another female Oerydus from the Tenasserim Valley resembles 

 G. biggsii, but the white of the forewing occupies the whole disc and 

 two-thirds of the cell, just reaching the hind margin and covering near- 

 ly half the area of the wing. The hind wing is all brown, and the under- 

 side much as in biggsii. 



Subfamily LIPHTRIN^. 

 I saw what I supposed to be a male of this species, near Myitta, 

 flying slowly in tho twilight. Having no net with me, I lost it. The 

 species of Allotinus are also often seen flying almost till dark.
