50 PROCEEDIXGS OF THE NATIONAL MUSEUM vol.93 



paratype, Tempe, Ariz. (Wildermuth) ; one female paratype reared 

 from Phragmatobia assimilans var. franconia, Hymers, Ontario 

 (Dawson) ; 143 reared specimens bearing Gypsy Moth Laboratory note 

 numbers (3 males reared from Estigmene acraea are paratypes, Nos. 

 10046 CM and E31) ; one male and one female reared from arctiid 

 (Dimmock) , removed from the Sisyropa eudryae material ; one female 

 reared from E. acraea Raleigh, N. C. (Brimley) ; seven males and one 

 female (Aldrich, Townsend, Eddington) ; seven males and four females 

 from Idaho, Utah, Texas, Arizona, and Maryland ( Aldrich, Mitchell, 

 Caffrey, Shannon), removed from the Carcelia "cheloniae" material. 

 One specimen determined by Townsend as ( 'ara lia was reclinata; this 

 specimen has only three postsutural dorsocentral macrochaetae. 



One male paratype of Carcelia reclinata with puparium from the 

 Gypsy Moth Laboratory, June 16, 1916, is C. laxifrons Villeneuve. 



The puparia of Carcelia reclinata and C. cheloniae are alike in their 

 major characteristics. The stigmal plates are about flush with the 

 surface of the puparium, and they are distinctly not protuberant ; the 

 stigmal slits are plain. The stigmal plates of C. cheloniae are far 

 above the longitudinal axis or subdorsally located, whereas in C. re- 

 clinata they are almost centered, being only slightly above. 



Essig records Zenillia reclinata as having been commonly reared 

 from Estigmene acraea in New Mexico and Arizona. The material 

 that the writer examined from Arizona and New Mexico consisted of 

 collected specimens; none of it had been reared. 



Adults, January to September (depending upon the climate) ; 

 number per host, one to several; generations, two or more; hiberna- 

 tion, larva in host larva (the indications are that Carcelia cheloniae 

 also hibernates in this manner).
