Sept., I9I3.] Forbes: Table of Species of Hadena. 181 



In Hyppa the thorax is strongly flattened dorsally, without decided 

 tufts, but with feathery vestiture. 



In Parastichtis (Tcrniosca) the palpi are upturned to the vertex, 

 body slender, and eyes slightly lashed. 



In Euplcxia there is a single much enlarged tuft on the third seg- 

 ment of the abdomen, and the vestiture of the patagise is evenly cut 

 off, not loose and hairy, at the edge. 



Delta (Actiiiotia of American authors, but not of Europe) has 

 massive tufts of hair on the tibiae. 



Prodcnia and Laphygma have triangular translucent hind wings, 

 with narrow dark veins and border. The thorax is not distinctly tufted 

 in front, but has a strong spreading or divided tuft behind. In Pro- 

 denia there are several abdominal tufts, and in Laphygma but one. 



Magusa has very large triangular hind wings and very narrow fore 

 wings. 



Homoliadcna has imbricate, apparently scaly vestiture as a rule, 

 sometimes overlaid with hair; the eyes are distinctly lashed and the 

 frontal vestiture is short and fine, unlike that of any other lashed- 

 eyed forms. 



Ommatostola and Cosuiia (Eiiargia) have no tufts whatever and 

 perfectly hairy vestiture, in Calyiiuiia the vestiture is a little coarser. 



In Apamea, Ipimorpha and Atcthmia the apex is acute, subfalcate, 

 and the outer margin perfectly even. The latter character distin- 

 guishes Conservnla also. 



Fagitana completely lacks M^ of the hind wing. 



Agrotiphila and Anchocelis have small eyes. 



In Lithomia, Xylina and Litholomia the frontal tuft above is very 

 large, divided both longitudinally and transversely, and the eyes are 

 strongly lashed. 



Cucullia and in a less degree Catabcna have much enlarged hood- 

 like tegulae, capable of being turned forward over the head. 



Pyrrhia, Xanthia, etc., are distinguished by the very prominent 

 anterior thoracic tuft or central ridge, Amathes by its heavily lashed 

 eyes, and most of the other Orihosiids by the strongly flattened 

 abdomen. 



In Brotolomia the outer margin of the fore wing is strongly irregu- 

 lar, and in Aiioinis there is a small raised white orbicular tuft besides.
