32 THE CANADIAN ENTOMOLOGIST. 



found it to be infested with the larvae of some species of longicorn beetle ; 

 I placed some of the sticks in one of my breeding cages where it remained 

 undisturbed until the 7th of May following, when I found that nearly all 

 the larvse had assumed the pupa form. The next examination was made 

 two weeks later, when nothing but perfect beetles were found. From this 

 it would seem that this species requires only one year to complete its 

 transformations. 



I am indebted to Dr. Horn for determining the above species.

l;v w. h. edwards, coalbukch, w . va. 



Argvnnis Butleri. 



Allied to ^4. Chariclea. 



Male. — Expands 1.4 imli. 



Upper side dark fulvous, the base of primaries largely black, of second- 

 aries still more, the black area extending to middle of disk, effacing all 

 markings ; the spots of both wings outside the basal area as in C/iariclea, 

 but the narrow spots on primaries are unusually large, with ragged edges, 

 and the mesial band is heavy and diffused; on secondaries this band is 

 lost in the black ground. 



Under side of primaries nearly as in Char idea, but there is scarcely any 

 yellow at apex or along hind margin, all this area being deep red ; a few 

 yellow scales only at apex and in middle of the marginal interspaces, to 

 represent the spots and patches of C/iariclea ; the submarginal lunules 

 almost lost in the red ground. 



Secondaries deep red, there being no yellow on the extra-discal area ; 

 the submarginal lunules and the rounded spots lost in the red ground or 

 very obscurely indicated ; the light band which limits the basal area is of 

 same shape as in Chariclea, but is nearly covered with red, the long tri- 

 angle at end of cell, and the rhomboid on costa, alone being white ; from 

 . this band to base the color is intense red, with a few white scales in the 

 interspaces at bast- : the macular silvery line around hind margin as in 

 Chitj'icli'ii.
