Gryon columbianus, sp. nov. 



9 . Length, 1.40"""'. Subrobust, black, opaque, closely, miimtely 

 punctulate; head transverse, wider than thorax, the anterior orbits, 

 broadly, and the cheeks, striated ; mandibles pale rufous ; scajx' and legs, 

 except coxa', brownish-yellow or pale rufous; tlagelluni brown-black. 

 Antenna' 12-jointcd, not (piite as long as the body; first and second 

 funiclar joints about equal, twice as long as the pedicel; third and 

 fourth minute, annular; club a little longer than the pedicel and 

 funicle united, rather stout, the joints tranverse-quadrate. Angles 

 of metatlnn'ax acute; post scutellar ridge emarginated at the middle. 

 Abdomen broadly oval, closely punctate, subopa(pie, sericeous, the first 

 and second segments with coarse stri;e, the apical margin of the sec-

IlAEiTAT. — District of Columl)ia. 



Types in Coll. Ashmead. 



Described from several specimens. 



Gryon flavipes, sp. nov. 



9 . Length, 0.r»0'""\ Black, shining, finely punctulate; face smooth, 

 polished; legs pale yellow; metathorax with obtuse angl*^s. Antennte 

 lli-jointed, brown-bhick, the scape, beneath, toward base, pale; first 

 funiclar joint a little longer than the pedicel; second shorter than the 

 first, not longer than thick; third and fourth, minute, transverse. Ab- 

 domen rotund-oval, smooth, shining, the first segment and the second 

 at the suture, striated; venter piceous. 



llAiuTAT — Ottawa, Canada. 



Type in Coll, Ashmead. 



Described from a single speciiueu received from l\[r. W. IT. Harring- 

 ton. Differs from the other species in the smoothness of the face, paler 

 legs, smoothness and seul[)ture of the abdomen, and the color of the 

 venter. 



Tribe IV. — Scelionini. 



A tribe allied to the Tclcasinl and always with the abdomen dis- 

 tinctly carinated along the sides; but, except in a few genera, the abdo- 

 men is much more elongated, being pointed or fusiform, rarely oval, 

 and exteiuls beyond the tips of the wings when folded, the third seg- 

 ment the longest, or the second and third are about equal in length. 

 The venation, however, is (piite distinct; the postmarginal nervure, 

 except in a few cases, is fully developed and usually longer than the 

 marginal, while the stigmal is never very short. When the postmar- 

 ginal nervure is absent the submarginal terminates in a stigma 

 {Bceoneura and SceUo).
