of silk and hair, the pupa also bcinfr similar to that of the Syntomidcp. 

 Three proups of genera have usually been placed in the Arvtiadce 

 which should have been referred to other families — NycUmera and 

 ils allies in the Old AVorld, and J'ericojns and allies in the Neo- 

 tropical rejiion, liave vein 8 of the hind wing separate from the cell 

 and connected with it by a bar, and should be placed in the Ilypsidce ; 

 whilst Sarrotliripa and the allied genera, which have been asso- 

 ciated with the 2\oUn(r, are better placed as a parallel development 

 in the Kociuido', having the ocelli present, vein 8 of the hind wing 

 free at extreme base, and the larvfc having the prolegs on somite 

 present ; and thirdly, Ecirias, UuUas, and allies should also be 

 placed in the Noduidn', having the oceUi present and vein 8 arising 

 free.

Proboscis usually fully developed, sometimes aborted ; palpi 

 porrect, sometimes oblique, the 2nd joint roughly scaled above and 

 below ; maxillary palpi minute, invisible, in ArcMnola large and 

 triangularly scaled ; frons and basal joint of antennae usually with 

 tui'ts of scales ; tibiae with the spurs long. Fore wing with tufts of 

 raised scales in cell, near base, at middle and at upper angle. Hind 

 wing with vein 8 coincident with the cell to near or beyond middle.
