many years for much valuable assistance and advice, and together 

 with whom I studied and discussed the present genus at Merton Hall 

 three years ago. 



8. Genus AGONOPTERYX Hubner. 



Agonopteryx Hubner, Verzeichniss bekannter Schmetterlinge, 1818, p. 410. 



Labial palpi long, curved; second joint with well-developed, fur- 

 rowed brush on the underside; terminal joint slender, acute, shorter 

 than second joint. Antennae simple in both sexes, with pecten on 

 basal joint. Tongue developed, scaled at base. Forewings elongate; 

 apex usually obtuse; termen rounded; 12 veins; 7 and 8 stalked, both 

 to costal edge; 2 and 3 stalked. Hindwings as wide or wider than 

 the forewings, with costa nearly straight, termen evenly rounded : 

 inner angle strongly developed, so as to cause a sinuation in the dorsal 

 edge; 8 veins; and 7 parallel; 3 and 4 connate or short-stalked; 

 5 cubital, approximate to 4. Abdomen flattened. 



Type. — Agonopteryx ocellana (Fabricius). 



This genus comprises Meyrick's section A of Depressaria, which 

 differs from section B in having veins 2 and 3 in the forewings stalked. 

 Through the kindness of Mr. Durrant I have lately received advance 

 proofs of parts of Lord Walsingham's paper in Proceedings of the 

 Zoological Society of London for 1907, from page 955 of which I 

 learn that he has adopted Wallengren's idea of separate genera for 

 the two groups, which indeed seems logical. 



The described American species, which are referable to this genus,
