Besides the type series the National Collection contains the follow- 

 ing representatives of this species: Six specimens reared by R. A. 

 Cushman from the grape berry moth at North East, Pennsylvania, 

 under Quaintance No. 11081; two specimens from the same host, 

 Polychrosis viteana^ and the same locality, under Quaintance No. 

 10907 ; one specimen reared by D. Isely from a leaf -miner on Prunus 

 se7'otina, at North East, Pennsylvania, under Quaintance No. 10961; 

 one specimen, without locality label, reared from Cacoecia rosaceana 

 under Bureau of Entomology No. 46° ; several specimens reared by 

 C. R. Ely at Washington, District of Columbia, from Gracilaria^ 

 species. In addition, the writer has seen a number of specimens in 

 the Cornell University collection, which were collected at Ithaca and 

 McLean, New York. 



In the opinion of the writer, polychrosidis is distinct from fumi- 

 feranae^ being distinguished from that species by the yellow tegulae, 

 by the smoother and more polished disk of scutellum, by the indis- 

 tinctly punctate mesoscutum, and by the usually darker legs. Ap- 

 parently it is identical with clavatus Provancher, agreeing with 

 Provancher's description, also with notes on clavatus made by A. B. 

 Gahan after an examination of the type, which remains in the Pro- 

 vancher collection at Quebec. However, since the type specimen is 

 badly broken and in generally poor condition, the synonomy is 

 queried. Should polychrosidis and clavatus prove to be identical, 

 clavatus would be the valid name.
