figure, however, if it is really this insect, is misleading, with 

 its small, frail body, white thorax and abdomen, without spots. 

 The locality also, West Indies, is wrong, as all the specimens 

 that I have seen are from the mainland, from Brazil to Costa 

 Rica. 



Trosia misda Schaus. 



Edebessa misda Schaus MS. 



In this the fore wings and thorax are pale ocher yellow, the 

 costa, vertex, thoracic spots, abdomen, and hind wings bright 

 red. The row of spots across the fore wing is black. The 

 species has the wing-shape and size of dimas. The female is 

 colored exactly like the male, but is larger. 



The type specimen is from Castro, Parana, Brazil. Others 

 are from the Guianas, Venezuela, Peru, Costa Rica, and 

 Mexico. There is local variation in size and in the black dots 

 on the fore wings. The Guiana specimens are the largest. 



Type: No. 12524, U. S. National Museum. 



Trosia beggoides, new species. 



White, the wings smooth and silky. Costa of fore wing black. 

 Head strongly tinged with yellow, the thorax and the abdomen less 

 strongly so. Orbits, palpi, pectus, and all the tarsi black. Expanse, 

 male 34 mm. ; female 50 mm. 



One male, one female, Castro, Parana, Brazil (E. D. 

 Jones) and Nova Friburgo, Brazil (Schaus collection). 

 Type: No. 13109, U. S. National Museum. 



Trosia euthula, new species. 



White, with a faint creamy tint. Pectus and femora smoky black ; 

 antennae testaceous. Expanse, male 24 mm.; female 30 mm. 



Four males, three females, Sapucay, Paraguay (W. T. 

 Foster). 



Type: No. 13110, U. S. National Museum. 



A small species, exactly like No) ape bu fieri Baker, but a 

 little less pure white and different in venation. 



Trosia revocans Felder. 



Endobrachys revocans Felder, Reise Novara, Lep., pi. Ixxxiii, 

 fig. 17, 1874. 



Kirby strangely places this genus in the Notodontidae. I 

 have not any specimens of the species, but consider it plainly 

 a Trosia, allied to pnJchella Schaus.
