XIII. 0)1 tlie classification of three suhfamilies of Moths 

 of^ the family PyralidtB : the Epipaschiinaj, Endo- 

 trichin£e, and Pyralinas. By Sir George F. 

 Hampson, Bart., B.A. 



[Read April 1st, 189(5.] 



The three subfamilies of PijralidcV, the Epipaschiinfe, 

 Endotrichinse, and Pyralinx, of which a classification is 

 here attempted, all belong to the group of Pyralidse 

 which have the median nervure of the hiadwing non- 

 pectinate on upperside, and vein 7 of the forewing stalked 

 with 8, 9. 



The Epipaschiinee, which are the ancestors of the sub- 

 family Phycitina', are to be distinguished from the allied 

 subfamilies by having small tufts of raised scales on the 

 forewing below the cell and on the discocellulars ; the 

 proboscis is fully developed, and vein 8 of the hindwing 

 is either free or anastomoses with 7, whilst a large 

 proportion of the species have in the male sex a more or 

 less developed thickly-scaled corneous process projecting 

 backwards from the basal joint of the antenna3 over the 

 thorax. 



The Endotri'cliinx and Pyrallnai have the forewing 

 smoothly scaled, the former has vein 8 of the hindwing 

 anastomosing with 7, whilst in the latter it is free. 



The Endotrichinx may be distinguished from the 

 Chrysauginw by the former having the maxillary palpi 

 developed, whilst in the latter, which are almost confined 

 to the tropical and warmer temperate parts of America, 

 though a few species have spread into the Australian and 

 Malayan regions, the maxillary palpi are aborted. Finally 

 in the Pyralinx, the genera that have the proboscis 

 aborted may be distinguished from the few Schjenohiinee- 

 that have vein 7 of the forewing stalked with 8, 9, by vein 

 8 of the hindwing being free. 



The three subfamilies thus represent a branch of the
