Male: Black. Bases of tibiae, anteroexternal face of front tibia 

 and usually also of hind tibia, most of basitarsi except apices, hind 

 corner of pronotum, and usually lateroapical blotch on some or all of 

 tergites 2 to 5 white; tegula brown; wings hyaline, their apical 0.4 

 faintly infuscate. 



Female: Colored like the male except that the white markings 

 average a little more extensive. The specimen from Bottineau, 

 N. Dak., noted below, has coloration intermediate to the subspecies 

 nevadensis. 



Specimens: 5 cfcf, 20 99 from: District of Columbia; Maryland 

 (Glen Echo) ; Massachusetts ; Michigan (Midland County, Missaukee 

 County, and Roscommon County) ; New York (Ithaca) ; North 

 Carolina (valley of the Black Mountains) ; North Dakota (Bottineau) ; 

 Rhode Island (Westerly); Vermont (Fairlee); and Virginia (Falls 

 Church, Glencarlyn, and Upton). 



Dates of collection fall in June and July except for two collections 

 in May and one in August (May 9 at Glencarlyn, Va.; May 19 in 

 the District of Columbia; and August 25 at Bottineau, N, Dak.). 



One specimen bears the note that it was collected on Solidago and 

 another on Ceanothus. A male specimen in the U. S. National 

 Museum that was taken from a cocoon of Telea jpolyphemus in June 

 1944 by C. Brooke Worth has some manuscript notes associated 

 with it which are of unusual interest. Mr. Worth states that the 

 cocoon was collected at Washington, D. C, during the winter of 1944. 

 Since it had not hatched and was very light, the cocoon was opened 

 June 13, 1944. The trigonalid was %\athin the polypfiemus cocoon, 

 which also contained a perforated parasite cocoon, presumably that 

 of Enicospilus americanus (Ichneumonidae). The ichneumonid 

 cocoon contained some liquid and semiliquid material among which 

 could be identified the apparent remains of an ichneumonid larva 

 and its meconium. The trigonalid was between the walls of the moth 

 cocoon and the ichneumonid cocoon, alive and active, Schulz (1911) 

 reports rearing this species from a cocoon of Enicospilus americanus 

 within a cocoon of Telea polyphemus, a situation similar to that noted
