Type.—Qa.t. No. 2863, U.S.N.M. Type male and allotype female 

 (on same pin) selected. 



Host. — (Jecidomyia hacchai'icola Ashmead MS. 



Redescribed from the type series, seven females and one male. 

 Ashmead originally included 18 specimens in his type .series but I 

 find 10 of these represent several species differing from those selected 

 as the types. They remain undescribed.
