Coleophora coruscipennella Clemens. 



One perfect type, Clemens' No. 34, alar exp., 12 mm. 



Zeller made this common American species a synonym of the 

 European Coleophora fabriciella Villers, which is now known 

 under the name spissicornis Haworth, and it certainly would be 

 exceedingly diffcult to distinguish between them. Still, as long 

 as the life history and early stages of the American species is 

 unknown, there is a possibility that it may be distinct, and I 

 should have favored retaining it as such. A large series, collected 

 at light around Washington, D. C., and compared with Clemens' 

 type, is in the U. S. National Museum. 



Coleophora laticornella Clemens. 



One good type, Clemens' No. 35 ; alar exp., n mm. 



This proves to be the elm-feeding Coleophora, which has been 

 of some economic importance of late years through its occurrence 

 in large numbers in the parks of Brooklyn, N. Y. I have bred 

 a large series of this species and am unable to distinguish it from 

 authentic specimens (adults and cases) of the European Coleo 

 phora limosipennella Duponchel, which feeds on elm in Europe. 



Our present knowledge of the genus Coleophora in this 

 country is in such a hopeless state that I cannot indicate other 

 synonyms of this species, though they doubtless exist among the 

 67 described species. Our names have been given mostly 

 without knowledge of the food plants and without any com 

 parisons with previously described species. The present species 

 will probably be found among them under another name. 

 This, however, will not interfere with the much older European 

 name. 



A bred series, compared with Clemens' type, is in the U. S. 

 National Museum. 



Coleophora csenosipennella Clemens. 



The type of this species, Clemens' No. 36, is lost. I have not 

 yet been able to identify the species from the description with 

 certainty. 



Coleophora infuscatella Clemens. 



One type, lacking left wings, otherwise in good condition, 

 Clemens' No. 37; alar exp., n mm. 



I have no specimen exactly like this. 



Coleophora cretaticostella Clemens. 



One type, abdomen and right wings missing, Clemens' No. 

 38; alar exp., 12.5 mm. 



I have no specimen like this-. 



Incurvaria russatella Clemens. 



The type of this species, Clemens' No. 39, cannot now be 

 found.
