4 NEW NEOTROPICAL EVANIIDAE (hYMENOPTERA) 



loan of specimens in the Bolter and Nason Collections belong- 

 ing to the University of Illinois; to Mr. E. T. Cresson Jr., and 

 the American Entomological Society, for many courtesies. 



There are representatives of four genera recognized in this 

 article, all based upon specimens from Brazil and three from 

 both Brazil and Peru. 



All types are in the collection of the author. Paratypes are 

 in the collection of the American Entomological Society. 



CHALCIDOPTERELLA Enderlein 



There is but a single specimen of the genus ChalcidoptercUa 

 Enderlein in the collection, and that is from Brazil. This 

 genus is numerically very small, containing but six described 

 species, all from South America and the West Indies. The 

 genus was erected by Enderlein in 1909, and contains three 

 species listed by Bradley under the name Evcmicllus Enderlein. 

 The genus Evmiiellus is now restricted Ijy both Enderlein and 

 Kieffer to a single species. The two genera are distinguished 

 solely by the presence or alisence of a trace of the suljmedian 

 vein. The difference is so slight that recently Brues^ has de- 

 scribed a species from Haiti under the generic name Chalcid- 

 optereUa, which he says could be placed in the genus Eimmelhis 

 because of the presence of a chitinous fleck denoting the j^resence 

 of the submcdian vein. This he judges is too trivial a character 

 \\\)o\\ which to base a genus.
