sides of face, several rather long black spurs, and numbers of others of irregular 
sizes on the face, some quite minute, part of them yellow, part black, each tipped 
with concolored hair. (Fig. c.) 
Chrysalis. — Length .7 inch ; greatest breadth .24 inch ; shaped nearly as in 
(r. Comma; cylindrical, slender; head-case high, compressed transversely; on its 
under side two protuberances, each ending in a short tubercle; at each vertex a 
short, stout, conical process, the space between square; mesonotum elevated, fol¬ 
lowed by a deep excavation; the carina rising to a high, thin, nose-like promi¬ 
nence; wing-cases much raised above the general surface, depressed laterally; 
on the marginal border of ventral side a sharp protuberance; on the abdomen 
several rows of tubercles, mostly small, but .those corresponding to the first lateral 
spines of the larva large on the anterior segments; those in the excavation sil¬ 
vered ; color marbled with shades of salmon and olive. (Fig. cl) 
The larva fed on wild currant, and a number of examples were found by Mr 
Mead at Yo Semite and bred to the imago. I am thus able to correct an error 
m olume I.,m which the larva and chrysalis of G. Rustims are attributed to 
/ 'ephyrus . 
As m the case of Rusticus, the present drawings have been made from alcoholic 
specimens and a blown skin of the larva, aided by Mr. Mead’s carefully written 
descriptions. J 
Both larva and chrysalis closely resemble those of G. Prague, and these stages, 
as well as the imago, show that the two species belong to one sub-group.
