ZENILLIA AND ALLIED GENERA — SELLERS 81 



nence at the base of the stigmal plates, the puparia of A. estigmenensis 

 are very similar to those of Carcelia reclinata (Aldrich and Webber). 



Type and allotype locality. — Hartford, Vt. 



Distribution. — Maine 1, New Hampshire 3, Vermont 1, Massachu- 

 setts 7, Rhode Island 1, Montana 1, Colorado 2. Published records 

 not duplicated above: Ontario 2 (Coquillett, Tothill) ; Aldrich lists 

 Idaho 1, Utah 1, and Colorado 1; Minnesota (Washburn); Maine 

 (Johnson) ; ? New York 2 (West). 



Type.— Mate, U.S.N.M. No. 54143. 



Hosts. — Estigmene acraea (Drury) 5, PhragmMobia fuliginosa 

 rubricosa Harris 7, Isia Isabella (Abbot and Smith) 2, Diacrisia vir- 

 girdca (Fabricius) 1. Published records not duplicated above : Phrag- 

 matobia fuliginosa (Linnaeus) (Tothill), Arctia sp. (Coquillett). 



Remarks. — The material examined consisted of 15 reared specimens 

 bearing Gypsy Moth Laboratory note numbers. This included the 

 type, allotype, and male paratype, No. 10046 B5; 2 female paratypes, 

 Bangor, Maine, No. 10046 E19; 1 male and 2 female paratypes, Revere, 

 Mass., Nos. 12140 B and Bl. It also included 1 male and 4 female 

 collected specimens (Aldrich, Hunter). 



Practically all the differences between Aplomya estigmenensis and 

 A. affinis are relative. Sixteen specimens collected at North Saugus, 

 North Andover, and Melrose, Mass., favor to some extent the A. affinis 

 characters. As these specimens apparently were collected at former 

 liberation points of Porthetria dispar parasites, the writer offers the 

 suggestion that there is a possibility that the European species might 

 have been accidentally established in this country. 



Adults, May to October; generations, two or three; number per 

 host, one or two; hibernation, as larva in host larva.
