 Esq.

 black, sub-ovate; secondaries have a short black tail; fringes brown, 

 black at anal angle and between this and the tail whitish. 



Underside dead leaf brown, greyish next base; both wings have a 

 submarginal row of obsolete points^ the three next anal angle alone 

 being clearly visible without a glass; the first from angle surmounting 

 a faint grey space ; across the disks a row of faint brown spots indis- 

 tinctly edged without by whitish ; thorax beneath grey; antennas black

California. From a single specimen in collection of Dr. H. Behr. 



Lyc^ena Orcus, n. sp. 



Male. Expands 1.1 inch. Upper side pruinose blue, paler on costa 

 of primaries; hind margins broadly fuscous; fringes long, cinereous. 



Under side grey cinereous, bluish at base; on arc of primaries a 

 narrow black bar bent outwards, and faintly edged without by white : 

 on secondaries a faint discal streak ; both wings have a submarginal 

 line of points, scarcely discernible. 



Beneath, thorax covered with blue grey-hairs, abdomen grey; palpi 

 white above at base, black at tip, and cinereous below; antennae black 

 annulated with white ; club black, tipped with cinereous. 



From a single specimen in the collection of Henry Edwards, Esq., 

 of San Francisco. This species differs from all other American Lycae- 

 nidae that I have seen by the absence of decided markings on the un- 

 derside, the usual discal row being wanting, and the submarginal 

 scarcely to be distinguished without a glass.
