 Cyathissa ochracca Smith. Can. Ent., xxxviii, 225, 1906.

 which the green color of the fore wing had been discolored. 

 This green commonly turns to orange if wet in the relaxing 

 jar. My specimens show all grades, and it is only those that 

 have been most carefully handled that retain the green com- 

 pletely. The name ochracea may stand as a variety in which 

 the black shadings in the medial area are reduced. Smith's 

 specimens were evidently discolored as with quadrate, hence 

 the misleading name. The variety appears occasionally among 

 normal specimens. 



Emarginea dulcinia, new species. 



Fore wing white, shaded with olivaceous green ; a black 

 angular expanded mark at base, and two on costa ; inner line 

 black, broken in the middle, excurved in the cell and below 

 vein 1 ; upper half of median space shaded with black, con-
