By Mr. Kirby’s permission I am able to add the remark that doubts rest on 
identification of this species. The first part of Walker’s description, which should 
be typical, seems to refer to M. arcuata, but it also seems to me to refer to a 
species like M. C. album, but without the first white stripe. The second part of the 
description refers to M. C. album, and the figures quoted to M. Uaveola. 
Size, 18 x 15 mm. 
Habitat. — Cayenne, Amazons, Para, Surinam.
