 Hemileuca dukinfieldi Schaus. 



Hemileuca dukinfieldi Schaus, Proc. Zool. Soc. Lond., 1894, 

 235. 



Described from Castro, Parana, Brazil. The types are be- 

 fore me. This species is only distantly related to the forms 

 here treated, and is included as the extreme development of 

 this type. 



Hemileuca rubridorsa Folder. 



Hemileuca rubridorsa Felder, Reise der Novara, pi. 90, fig. 2, 



1874. 



Felder's description is without definite locality; his figure 

 represents a female. A female specimen from the Schaus 

 collection is before me labeled "Mexico," without definite lo- 

 cality. It is also labeled " Enlencop/ucns norba Druce," but 

 it differs from that in the uniform gray hind wings without 

 submarginal pale band and in the broader yellow costa. It 

 agrees well with Felder's figure. A male also is before me, 

 collected by Mr. R. Miiller in Mexico City, which enables a 

 definite location for the species.
