(2) Lycaena heteronea, Boisduval, Plate XXXI, Fig. 13, $ ; 

 Fig. 14, ? ; Plate XXXII, Fig. 19, ?, under side (The Varied Blue). 



Butterfly. 'On the upper side the male is blue, the female 

 brown. On the under side the wings are white, with faint pale- 

 brown spots on the hind wings and distinct black spots on the 

 fore wings, more numerous than in L. lycea, which it closely 

 resembles on the under side. It is the largest species of the 

 genus, and the female reminds us by its markings on the upper 

 side of the females of Cbrysopbarnis. Expanse, 1.25-1.40 inch. 



Early Stages. These await description. 



Heteronea ranges from Colorado to California, at suitable ele- 

 vations among the mountains. 



(3) Lycaena clara, Henry Edwards, Plate XXX, Fig. 26, ? 

 (The Bright Blue). 



Butterfly. The figure in the plate is that of the type of the 

 female, the only specimen in my collection. Expanse, 1.15 inch. 

 Early Stages. These are entirely unknown. 

 The type came from southern California. 



(4) Lycaena lycea, Edwards, Plate XXXII, Fig. 18, $ , under 

 side (Lycea). 



Butterfly. The perfect insect is very nearly as large as L. bet- 

 eronea. The male is lilac-blue on the upper side, with the mar- 

 gins dusky. The black spots of the under side do not show 

 through on the upper side, as in L. heteronea. The female is 

 dusky, with the wings shot with blue at their bases, more es- 

 pecially on the fore wing. There are no black spots on the 

 upper side of the wings in this sex, as in L. beteronea. On the 

 under side the wings are whitish. The spots on this side are 

 well delineated in our figure in Plate XXXII. Expanse, 1.30 inch. 



Early Stages. These await description. 



The butterfly is found in the region of the Rocky Mountains, 

 from New Mexico to Montana.
