LEP1DOPTERA LYCAENIDAE LYCAENA PIASDS. 785 



species. The shade of blue above is quite different from that of Lygdamas, 

 and more inclined to purple. 



LYC^NA LYCEA, Edw. 

 Lyccena Lycea, EDW., Proc. But. Soc. Phila., 18G4. 



This species is especially abundant on the outskirts of Denver early 

 in June. They are usually found among wild Blue Lupines, which there 

 are common weeds, and very possibly the larva may feed upon this plant. 

 Later in the season, in the South Park an empty egg and a caterpillar, 

 both evidently of some Lyccena, were found on wild lupines. The larva 

 was pale green, with one or two whitish dorsal stripes, but was lost before I 

 had an opportunity to make a detailed description. L. Lycea is a very 

 variable species ; the black dots on the under surface are often encroached 

 upon by their white margins to such an extent that only minute points 

 remain. The species remains on the wing till August. About seventy 

 specimens were taken. It was brought from the South Park by the expedi- 

 tion, but is not known to occur outside of Colorado.

 Utah; it occurs also in Nevada and California, 



LYCCENA DAUNIA, Edw.

Three specimens of this species, the only known examples, were taken 

 on Turkey Creek during the last week in June.
