furrows (implied) sessile abdomen, the species falls near the omphalinin'e 

 genus, Closteroceriis Westsvood. As I have not seen the species, however, 

 I think that Ashmead's later determination should be accepted for the 

 present, and so I have included it here.* 



Smith (1900), gives the following note concerning this species : "Lives 

 in Cecidomyid galls, widely distributed (Ashm.)." The species occurs in 

 Florida, District of Columbia and New Jersey. 



The types are probably in the United States National Museum^ 

 Washfngton, D. C. 



Table of Species. 



This table is constructed from the literature, and caution should 

 therefore be exercised in identifying species by its aid aione. It forms 

 merely an index to the species included within the group.

*It may be that Trichaporus Foerster, with Ashmead's cohanblanus as type^ 

 could be resurrected, while the group of Ashmeadian species now forming the: 

 genus, as here proposed, including the new species, could be renamed.
