NOTES ON CERTAIN NEARCTIC TRICHOPTERA 

 IN THE MUSEUM OF COMPARATIVE ZOOLOGY 



By Oliver S. Flint, Jr. 



Associate Curator, Division of Neuropteroids 



The collection of Trichoptera in the Aluseum of Comparative 

 Zoology at Harvard University is one of the most important deposi- 

 tories in the New World of types and other important material. 

 During the summers of 1961 and 1962 it was my good fortune to be 

 able to spend a number of weeks studying and preparing notes and 

 illustrations on some of this material. 



Many of the male types of Nearctic caddis flies in this collection 

 were illustrated by Ross (1938b) and most of the other species have 

 been figured or synonymized in later works of the same and other 

 authors. However, there remains a small number of species whose 

 status has never been clarified. In many instances the problem has 

 been that the type is female. Now, with oiu" increasing ability to 

 discriminate between the females of the various species, and with 

 the collection of longer series containing both sexes, it is possible in 

 many cases to associate these female types with the males of the same 

 species. In other cases the uncertainty about the species status has 

 resulted from the failure of the earlier workers to figure or study the 

 cleared, relaxed genitalia of the male types.
