Tynes in National Museums Described from 3 female 

 specimens received by Mr. L. O. Howard from Air. F. "W. Urich, 

 who reports having reared them from a Coccid, Dactylopius sp. 



This species belongs to that section of the genus, in which 

 the pedicel is longer than the first joint of the funicle. and it is 

 quite distinct from the several species described by the writer in 

 his recent " Report upon the Parasitic Hymenop>tera of the 

 Island of St. Vincent (Journ. Linn. Soc. Zool. vol. XXV., 1894, 

 pp. 201-210) or in his Monograph of the North Amercan 

 Proctotrypidse (Bull. 45 U.S. Natl. Mus. pp. 143 et seqa.) 



In general appearance it comes nearest to my Telcnomus 

 minimus taken at Arlington, Virginia, agreeing with it in 

 venation, but it is smaller and is readily separated from it by the 

 much wider head and the relative porportion of the antennal 

 joints.

 "spinnerets and the supporting hairs are as numerous and as 

 "prominent, or nearly so, as in D longifilis ; those upon the
