One .spccinicii in the U. S. National Miiscinn nunuHl l)y Lord Wai- 

 sing-ham I have compared and found identical with C'hainhers" type 

 in tlu^ ]VIuseum of Comparativi^ Zoology in Cani])ridov. 



The \ ('nation of this species differs from that of the type of the 

 genus oidy in the forewing-, where vein S is absent, coincident with 7, 

 which is \-ery nearly the case in the other species also, wh(»re the stem 

 of the fork of 7 and S is very long and the ))ranches short. 



The other differences in venation mentioned by Chambers are not 

 borne out by the specimens, and the identical wing form and other 

 characters place the species naturally in the same genus.

Labial palpi very long, curved, se<-ond joint smooth, terminal joint 

 longer than second. })ointed. Forewings narrow, elongate pointed; 12 

 veins, 7 and 8 stalked, (> somc^times out of 7 near base. Hindwings 

 narrower than forewings, elongate trapezoidal, apex produced, pointed, 

 term n emarginate: 8 veins. (5 and 7 stalked, 3 and 4 connate, 5 approx- 

 imate to 4. 



Lord Walsingham pointed out' that the name Andaiinpslx hitherto 

 had been applied erroneously to this genus instead of to the genus 

 known as 7ac/ii/2)flJl(i Heinemann, containing the type of An(/campsis, 

 Tlntd popiih'lJii Clerck, as speciffed by Curtis.- Mr. Durrant therefore 

 proposed the name Apt'oaei't-nin for the geiuis thus left nameless, the 

 tvpe of which is untliyJlidcUn Hiibner. 



The o-enus is developed fi-om Anacampsis^ Curtis {Tacky ptilla Heine- 

 mann), with a section of which it has great similarity in coloration, 

 l)ut it is easily distinguished by the sinuate hindwings. 



All the species feed on leguminous plants. 



I have recognized the following American species which may be 

 separated by the table: 



Forewings black or nearly so 1 



Forewings lighter 4 



1. Labial palpi with longitudinal white lines 2 



Labial palpi without such lines 3
