Museum collection two tagmounted females labelled respectively: 

 " Cosmocoma cecanthi Ashm. Delaware. Amer. Ent. Soc. To be 

 returned " and " Bred from eggs of CEcanthus by H. S. Smith. Ex. 

 eggs of CEcanthus. Melrose Highlands, Mass." 



This species was originally described from specimens reared in 

 the District of Columbia and is now recorded from Kansas, Dela- 

 ware, Texas and Massachusetts, and thus must be widely distributed 

 in the United States ; I have never seen it in Illinois though other 

 members of the genus are common there on windows and in 

 sweepings. . More recently I have a specimen from N. Y. 



The species was first mentioned in the literature by Pierce (1907) 

 under the name of Polynema cecanthi Ashmead, a nomen nudum. It 

 was reared by him from the eggs of an CEcanthus in the stems of 

 Grindelia while studying weevils and their parasites. The specimens 

 just mentioned as having been received from him are undoubtedly the 

 ones referred to in the place cited. 



Genus Stichothrix Foerster. 

 I. Stichothrix bifasciatipennis Girault. 



As has just been shown this species is a Polynema.
