Studies of Neotropical Caddis Flies, IV 

 New Species froin Mexico and Central America 



By Oliver S. Flint, Jr. 

 Curator, Division of Neuropteroids 



During the past few years the insects of Mexico and Central 

 America have been collected extensively by several members of the 

 Smithsonian Institution's Department of Entomology. In 1963 

 W. D. Duckworth and D. R. Davis collected in northeastern Mexico 

 (A.P.S. grant J-493). P. J. Spangler collected widely in Mexico in 

 1964, and, in 1965, on another trip, he collected as far south as Costa 

 Rica (N.S.F. grant GB-1697). El Salvador, Costa Rica, and Pan- 

 ama were sites of collections in 1965 by W. D. Duckworth (N.S.F. 

 grant GB-1800). I collected widely in Mexico and Guatemala in 

 1965 and 1966 (N.S.F. grant GB-2616). In addition to this material, 

 other specimens are included whenever available. The holot} 7 pes of 

 all new species are deposited in the U.S. National Museum. 



Thirty-one species are described as new in this paper. There are 

 many more probable new species in the collections, but because of 

 then close relationship to known species they are not described 

 herein. It is hoped that in time additional material will show whether 

 or not these specimens represent mere variation or in fact are valid 

 species.
