them are marked faintly with yellow, the one which crosses the spiracle 
on joint 5 distinctly so. A yellow substigmatal line on joints 11-13. 
Dorsal band widened on joint 2 anteriorly, also trian<j:nlarly on joint 7. 
It is red-brown, mottled with whitish, and bordered with yellow, marked 
in darker shades on joints 2, 5, 7, and 11. 
Cocoon.— Composed of silk, thin, parchment-like, formed among loose 
material at the surface of the ground. 
Food plant.— Oak (Quercus). 
Larva from Dutchess Co., New York. 
The larva of Cerara scolopendrina has not been described, but 
I believe that I have observed it. No motlis were bred from the 
Larvae here described ; but several considerations render it prob- 
able that they are C. scolopendrina, so that I venture to present 
my notes under the name. 
(1) C. scolopendrina is common tliroughout California and 
was taken by me in Yosemite. 
(2) These larvae have not been described before, and could 
only be C. paradoxal of the known Californian forms. 
(3) I am informed by Dr. Thaxter, who has bred it, that the 
larva of C aquilonaris (= scolopendrina) is much like that of G. 
cinerea, and those liere described recall cinerea in the undulating 
outline of the dorsal patch. 
(4) Dr. Beiir writes in answer to an inquiry: "[In tlio larva 
of] Genera scolopendrina tlie dorsal baiul ... is tliree times 
widened, or I would call it twice constricted, but the degree 
of the constriction is rather variable, so that sometimes, altliough 
rarely, the band is almost interrupted."

1 There is good reason to believe that C. paradoxa is only a very pale form of C. 
cinerea, the larva of which is well known.
