Saturniidae 
the present time has succeeded either in reeling or carding 
the silk of the cocoons. 
(2) Callosamia angulifera Walker, Plate VIII, Fig. 3, $ , 
Fig. 4, $ . (The Tulip-tree Silk-moth.) 
This species may easily be discriminated from the last named 
by the fact that the males are not without discal spots as in that 
species, but have large angular white spots, causing them to 
resemble in this respect the females of C. promethea. The larva 
feeds commonly on the tulip-poplar (Liriodendron). The cocoon 
is not suspended from the twigs, as in the case of C. promethea. 
The only other species of the genus, which occurs in our fauna, 
is Callosamia calleta Westwood, which may be differentiated 
from the two foregoing species by the fact that it has a whitish 
band on the collar and at the base of the thorax. 
SUBFAMILY SATURNIINvE 
The discal cells are closed. The antennae are pectinated in 
both sexes 4 o the tip. The hind wings have but one internal 
vein distinctly developed. But four genera representing this sub¬ 
family are found within our territory. 
Genus AGAPEMA Neumoegen & Dyar 
The antennae of both sexes are doubly bipectinated, those of 
the female having both the anterior and posterior pectinations of 
equal length. Only one species is known. 
(1) Agapema galbina Clemens, Plate IX, Fig. 3, $ . (The 
Galbina Moth.) 
This interesting insect occurs in southern Texas, Arizona and 
Mexico. The larval stages have been described by Flenry 
Edwards (see “Entomologica Americana,” Vol. IV, p. 61). The 
specimen figured is considerably darker than the figures given 
by Strecker. Specimens as light as those he depicts have never 
fallen into the hands of the author. 
Genus ACTIAS Leach 
The species of this genus may easily be discriminated by their 
pale green color, and the tailed fund wings. The pectinations of 
the antennae in the female sex are shorter in the anterior pair on 
86
