Rusohria megnptera, sp. n. 



2 . Shortly pilose, smooth, shining, red ; the antennae, 

 head, the abdomen (except the basal segment), the pos- 

 terior coxffi, femora and base of tibijfi, the middle coxje at 

 the apex, a line on the femora, and on the base of tibire, 

 black ; the tibite and tarsi clear white ; the apical joint 

 of the tarsi blackish. Wings yellowish ; the apical third, 

 and the posterior, except the upper basal and middle 

 parts, black. The nervures (except on the black parts of 

 the wings), costa and stigma, yellow. 



Length 4| lines; alar exp. 11 lines. 



Hab. — Brazil (Swainson). 



The antennse are, properly speaking, fuscous, as is also 

 part of the abdomen ; but this is probably owing to the 

 original black colour having faded through age.
