Scopariayicp, with tufts of raised scales in the cell of fore wing, 

 from forms with dilated maxillary palpi such as Pionea ; (2) the 

 Eydrocampinw, by vein 10 becoming stalked with 8, 9, from 

 forms ^^■ith filiform maxillary palpi ; (3) the Fyralino'., with vein 7 

 stalked with 8, 9, from a form with vein 8 of hind wing free, 

 giving rise to (a) the EndotricMnce. with vein 8 anastomosing 

 with 7, from which arose the Chrysaugince with the maxillary 

 palpi absent, and (6) the Epipaschiance with tufts of scales in cell 

 of fore wing, giving rise to the Phi/citiiue with vein 7 of fore wing 

 absent and the median nervure of hind wdng pectinated, from 

 which arose the Anemstiance with the proboscis absent ; (4) the 

 ScJicenobiance with the proboscis absent ; and (5) the Crambince, 

 with the median nervure of hind wing strongly pectinated and the 

 maxillary palpi triangularly scaled, giving rise to the Qallerianre 

 with the maxillary palpi slightly dilated or filiform.

^ Except in a few genera of Pyralinm to be distinguished from the Schano- 

 biancB by vein 8 of hind wing being free. 



* Except in a small percentage of specimens of a few species of Nympliula 

 and OHgostigma to be distinguished from nearly all Pyraiistiiiw by the long 

 maxillary palpi dilated at extremity.
