Subfamily PYRAUSTINiE 



Head smooth; ocelli present. Male antennae normal with a few exceptions (the 

 most striking ones in our fauna are Pilocrocis and Desmia). Front very often 

 oblique (fig. 344, etc.), extending out 

 below, in a few genera conical (fig. 339), 

 and in some western and exotic forms with 

 a specialized process. Tongue strong, 

 scaled; maxillary palpi small but distinct, 

 rarely if ever as long as second segment 

 of labial palpi. Labial palpi of various 

 shapes (figs. 326 to 344), usually with 

 short third joint. A distinct row of scales 

 between antennal socket and eye. Hind 

 tibise sometimes with the outer spurs in 

 the male rudimentary. Fore wing usually 

 triangular, ample, rarely as bluntly 

 rounded as in the Glaphyriinse, narrow 

 in Nomophila ( fig. 323 ) . Hind wing of 

 moderate size, ample in Nomophila. Fore 

 wing with R t and R 2 free, R 3 and R 4 

 stalked except in a couple of exotic genera; R 5 free, often approximate to R 3+4 at 

 the base, M 1 approximate to R 5 . Hind wing with Sc and R anastomosing except in 

 some specimens of Loxostegopsis (fig. 325) and a few exotic forms; M 1 arising from 

 upper angle of cell; Cu with a very slight fringe at base, or none; frenulum of 

 female multiple. All veins present in both wings. 



This is the largest and the most varied subfamily of Pyralididse, but very few
