2. On the Classification of the Ch.rysaugm<B, a Subfamily 

 o£ Moths of the Family PyralidfB. By Sir George 

 F. Hampson, Bart., F.Z.S. 



[Eeceiyed April 8, 1897.] 



The Chrysaugince are a highly specialized subfamily of the true 

 Pyralid group of the large family Pyrcdidce, consisting in addition 

 to the present subfamily of the Epipaschiant^, Endotrichhue, and 

 Pyralince, lately classified by me in the ' Transactions' of the Ento- 

 mological Society, and characterized by vein 7 of the fore wing 

 being stalked with 8, 9. The C'hrysauginm as here defijied are 

 primarily distinguished from their allies by the abortion of the 

 maxillary palpi, which are well developed in almost all other 

 Pyralidce. They are closely allied to the EndotricJiince but, as vein 

 8 of the hind wings is in rare instances free, were probably derived 

 directly from the Pyralince as a parallel development to the 

 Endotrichince. The latter are almost confined to the Old "World, 

 though a few species are found in the Nearctic region, and one 

 genus _ in the "W. Indies; whilst the Chrysaurjince are almost 

 exclusively Neotropiccd, a few genera and species being found in 

 the Southern States, and a few others spreading through the 

 Australian^ region to the Malayan subregion, the furthest points 

 reached being Burma and Assam. 



The subfamily is remarkable for the great sexual diversity found 

 in the subcostal neuration of the fore wing in a large proportion 

 of the species, the females always having veins 7, 8, 9 stalked, as
