them all here together for convenience of comparison. The cheeks 

 of Gruniis are flushed, like those of Dryope, and in other aspects 

 it carries the same face as the other two, but on underside there 

 are no markings whatever, all the dots usually seen are paled out 

 entirely.

 Brown above; black-brown beneath, with a small ashy-blue 

 spot at anal angle of hind vv^ing, which spot is the best key to the 

 species ; there are other species that resemble Saepium, but the 

 blue spot is distinctive : it is not well shown in the figure, being 

 overshadowed by the black at that point.

 On upper side wine-red. with a dark violet luster when fresh ; 

 on under side much as in Saepium, yet different, especially as the 

 blue spot of Saepium is absent in Chalcis : the whole under side is 

 of a peculiar smoky tint, or in the female, bronzy. Chalcis is a 

 mountain species, and is not found on the lowlands at any place ; 

 apparently about 5,000 feet elevation is where it most abounds.

 This is a rare species, not being often seen. It flies on the high 

 mountains at 5,000 to 6,000 feet elevation. The under side is 

 peculiar in that it has a curved row of spots on the fore wing, a 

 feature that belongs more usually to the Lycaenas than to the 

 Theclas.
