PARASITIC HY.MKNXH'TKKA. 193 



Arctia virc/iuica ; besides a single 9 received from Prof. J. A. Willet, 

 Selnia, Ala., " reared from a cocoon found under pine hark ;" a sin- 

 gle specimen captured at large in xVlameda County, California, by 

 Mr. Albert Koebele ; and one 9 'i^ "ly collection from Tennessee. 



The species is, therefore, quite extensively distributed throughout 

 the country as 0. macrurum, and judging fnjm the above rearings 

 confines its attacks to various Arctiids. 



To this genus also belongs Thyreodon texamtx Ashm., Oj/hioii 

 slossonce Davis, is apparently a synonym of this species.
