XXXI V. — On the Noctuid Genera allied to Hypffitra of 

 Guenee. By Akthuk G. Butlee, F.L.S., F.Z.S., &c. 



The genera allied to Hypcetra have hitherto been in the 

 utmost confusion, M. Guenee having first produced it, not 

 only by associating differing structures under the same name, 

 but by placing closely allied genera under distinct families. 

 As a matter of fact Hypcetra and its allies are best placed in 

 the Ophiusidas of authors (which will take the name of 

 Dysgoniidai), and will stand between Ghrysorithrum and 

 Trigonodes. 



Genus AvATHA, Walk. 

 Avatha, Walk. Lep. Het. xiii. p. 1106. 



This genus will include the bulk of the species hitherto 

 included in Hyjycetra and Anereuthi7ia, from which they differ 

 in having the third joint of the palpi placed at an obtuse 

 angle to the second instead of in a line with it, and in their 

 somewhat less dilated hind legs ; in the pattern of their ante- 

 rior wings they differ in the less undulated transverse lines 

 and the greater tendency to produce black patches. The 

 type oi Avatha is A. includens. The species in the British 

 Museum are : —

Our specimen, although not corresponding witli Walker's 

 description, was identified by Mr. Moore, who had examined 

 the type in Mr. iSaunders^s collection from India.
