A Preliminary Revision of the Genus Trisuloides 403 



and is not curved. The dorsal fold ends in a short bifid process. Uncus 

 somewhat as in pygaria but is narrowed at the apex, and has a well- 

 developed keel on the back. Penis with cornuti generally distributed 

 over the end of the eversible membrane. Sheath with a thickened ring 

 of short spines at its upper end. 



In the specimens dissected the eversible membrane was retracted, 

 with its end about two-thirds down.

In view of the apparent rarity of pygaria Warr., and the large 

 number of specimens received of talboti, it has seemed advisable to 

 choose talboti as the type of A nep h olcia, rather than the longer-known 

 but apparently rarer pygaria.

Trisuloides pygaria Warr. 

 Nov. Zool., xix, 2 (1912) (W. Sumatra) (.$). 

 d , 54 — 58 mm. 



Antenna with moderate pectinations to beyond middle, shortening 

 gradually to serrations, which are continued almost to apex. 



Fore and mid tibiae very thickly clothed with long hair, the hind 

 tibia less densely clothed. 



Fore wing with the antemedial line angled outward just behind M, 

 not excurved at M ; the wing is somewhat rubbed here in the type and 

 has probably not been quite correctly seen ; the white patch beyond the 

 cell broken up by greyish shading between the veins; this patch may 

 probably be aberrational. 



Genitalia (pi. XVI, fig. 1) : — 



Valve square-shaped, narrow posteriorly. The dorsal and ventral 

 edges are thickened and folded in (characteristic of the whole group). 

 The upper part of each fold is more strongly chitinized, the anterior 

 third of the ventral fold being free, forming a finger-like process which 

 is curved round the edge of the valve. Uncus long and slightly curved, 

 fairly stout, apex square. Penis with one patch of cornuti on the 

 eversible membrane. Sheath strongly chitinized, its end obliquely 

 truncate, and with a row of short spines along its edge on one side.
