Hystricophora leonana AValsingham, Illus. Lepid. Heter. Brit. Mus., vol. 4, 

 1879, p. 65.— Fernald, in Dyar List N. Amer. Lepid., no. 5209, 1908.—

A co-type of this species is in the National Collection. It is dis- 

 tinguished from other species of Hysti'icophora by its slender harpes 

 and the shape of its fore wings. The latter are a trifle broader in 

 proportion to their length in leonana than in the others, and it also 

 has the costa somewhat arched. In the other species it is straight.

This, as Walsingham suggests, is probably nothing but a brighter, 

 more golden color variety of leonana. On the suspicion that it may 

 represent a local race I am holding the name. A specimen in the 

 Kearfott collection labeled " Co-type " looks like a typical leonmia. 



Alar expanse. — 19 mm. 



Type. — In British Museum. 



Type locality. — Shasta County, California. 



Food plant. — Unknown. 



3. HYSTRICOPHORA PARADISIAE, new species.
