204 ZYGiENID^ AND BOMBYCID^ 



BOMBYCID^. 



ARCTIIN5;. 



Genus HYPHANTRIA. Harris. 



"The structure of the fore and hind wings like those in the genus 

 Spilosoma. 



" Head moderate, somewhat sunken and woolly ; with ocelli. Face 

 tapering and vertical. Eyes moderately large. Antennse shortly pec- 

 tinated in the 3 , serrated in the ? . Labial palpi rather hairy beneath, 

 scarcely extending beyond the clypeus ; second joint very short, and 

 terminal joint nearly rudimental. Tongue nearly as long as the anterior 

 coxae, filamentous. 



"Structure of fore and hind wings as in the genus Spilosoma. 



" Body rather stout. Thorax woolly. Patagia not erected, rather 

 broad and flattened. Breast woolly ; abdomen rather smooth. Legs 

 with the femora woolly ; tibial spur of the fore legs long and curved, 

 hind tibiffi with a pair of small apical spurs. " 



"Mr. Walker does not recognize this genus, but refers the species 

 Dr. Harris placed in it to Euprodis Hiibner. The structure of E. 

 aurijlua does not, however, authorize this step. In it the antennae are 

 deeply pectinated in 5 ; the palpi are differently formed, the tongue 

 more rudimentary ; the costal and subcostal veins in the hind wings 

 distinct to the base, although connected in the middle of the cell by 

 an intercostal branch ; and in the fore wings the second subcosto mar- 

 ginal nervule arises between the post apical and apical nervulet. The 

 head is without ocelli, and the structure of the legs in aurijlua differs 

 from that in Textor. A consideration of these differences, and the 

 structural agreement of textor with other genera of the hm\\y Arctiince, 

 the habits and structure of the larva, can leave no doubt, I think, res- 

 pecting the true position and naturalness of the genus.'" 



Clemens, Proc. Acad. Nat. Sci. Phil., p. 530. (i860.) 



Three species of this genus are found in the United States ; two of 

 them {H. textor, H. cuneaj)2.xt well known, while it is doubtful whether 

 the third {H. punctata, Fitch,) is specifically distinct from H. cunea. 

 They may be distinguished thus : 



Wings white - - - . - - - H. textor. 



Wings spotted 



With many spots H. cunea. 



With single band of small spots - - - H. punctata.
