Lansing, Ionia Co., Midland Co., and Wayne Co.); Minnesota (Du- 

 luth and Ramsay Co.); New Hampshire (Jefferson); New Jersey 

 (Camden Co., Moorestown, New Brunswick, and Paterson); New 

 York (Brooldyn, Farmingdale, Ithaca, Kingston, Nyack, Six Mile 

 Creek near Ithaca, Stony Point, Tuxedo, and West Farms in New 

 York City); North Carolina ("Chasteen Creek" in Great Smoky 

 Mountains National Park); Northwest Territories (Norman Wells); 

 Ohio (Cleveland, Huron Co., and Scioto Co.); Ontario (Chatham, 

 London, Ottawa, and Toronto) ; Pennsylvania (Cresheim Valley near 

 Philadelphia, Mount Hope, Philadelphia, and Wissahickon-Fair- 

 mount Park near Philadelphia) ; Rhode Island (Alton) ; and Virginia 

 (Ai'hngton, Dayton, Falls Church, Great Falls, McLean, and Rosslyn), 



A large portion of the specimens are known or presumed to have 

 been reared. The collection dates of the specimens known or be- 

 lieved to have been collected as adults fall mostly in July and late 

 June, but the total range is from early to late summer. Unusually 

 early and late dates of specimens collected as adults are : May 26 at 

 New Brunswick, N.J.; June 1 at Ithaca, N.Y.; June 10 at Falls 

 Church, Va.; September 1 at Stony Point, N.Y.; September 7 at 

 Takoma Park, Md.; and September 18 at Alton, R.L 



Reared specimens or reared lots are: 30 rearings from Callosamia 

 promefhea, 1 from C. angulifera, 2 from Callosamia sp., 1 from Samia 

 cynthia, 1 from Antheraea polyphemus, 1 from Acronicta, 1 from Battus 

 philenor, 1 from "silk moth," and 1 "attacking man." The normal 

 host of the species is certainly Callosamia and records of other hosts 

 need verification. Parasitized Callosamia cocoons are packed tight 

 with the ichneumonid cocoons, which give rise to about eight adult 

 parasites, usually of both sexes. Overwintering is in the host cocoon 

 and emergence from cocoons brought indoors is from about February 

 to mid-summer. 



This species occurs in the Alleghanian and Carolinian faunas. Its 

 normal host is Callosamia.
