2 AECTIAD^. 



of silk and hair, the pnpa also being similar to that of the Syntomiclce. 

 Three groups of genera have usually been placed in the Arctiadce 

 which should have been referred to other families — Nyctemera and 

 its allies in the Old "World, and Pericojns and allies in the Neo- 

 tropical region, have vein 8 of the hind wing separate from the cell 

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

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

 ciated with the Nolince, are better placed as a parallel development 

 in the Noctiddce, having the ocelli present, vein 8 of the hind wing 

 free at extreme base, and the larvse having the prologs on somite 6 

 present ; and thirdly, Earias, Halias, and allies should also be 

 placed in the Noctuidce, having the ocelli 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 Arcliinola large and 

 triangularly scaled; frons and basal joint of antennae usually with 

 tufts 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.
