Butterfly. — On the under side the wings are pale gray, with 
the light spots of the primaries and a curved median band of 
spots on the secondaries whitish. Expanse, $, 1.10 inch; $, 
1.20 inch.

(3) Polites sabuleti, Edwards, Plate XLVII, Fig. 42, $ ; Fig. 
43, ? (The Sand-hill Skipper). 
Butterfly. — Small, the male on the upper side looking like a 
diminutive and darkly bordered phylaeus. On the under side the 
wings are paler than on the upper side; the still paler spots of 
the discal areas are defined outwardly and inwardly by elongated 
dark spots. Expanse, 1.00-1.10 inch. 
Early Stages. — Unknown. 
The habitat of this species is California. 
Genus HYLEPHILA, Billberg 
Butterfly. —The antennse are very short, scarcely one third the 
length of the costa of the fore wing; the club is robust and 
short, with a very minute crook at the end; the palpi are as in 
the two preceding genera. The neuration of the 
wings is represented in the cut. 
Early Stages. —As yet but partially known. 
The larva feeds on grasses, and the mature form 
has been figured by Abbot, a copy of whose draw¬ 
ing is given by Dr. Scudder in Plate 77 of “The 
Butterflies of New England.”

in the plate. On the under side the wings are
