Saturniidse 



the present time has succeeded either in reeling or carding 

 the silk of the cocoons. 



(2) Callosamia angulifera Walker, Plate Vlll, 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. promeihea. The larva 

 feeds commonly on the tulip-poplar ( Liriodendron). The cocoon 

 is not suspended from the twigs, as in the case of C prouiethea. 



The only other species of the genus, whj/;h 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 SATURNIIN/E 



The discal cells are closed. The antennae are pectinated in 

 both sexes to 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 8c Dj^ar 



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. 



(i) Agapema galbina Clemens, Plate IX, Fig. 3, i . (The 

 Galbina Moth.) 



This interesting insect occurs in southern Texas, Arizona and 

 Mexico. The larval stages have been described by Henry 

 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 hind wings. The pectinations of 

 the antennae in the female sex are shorter in the anterior pair on
