Habitat — Ottawa, Canada. 



Type in Coll. Ashmead. 



Described from a single speciwien received from Mr. W. II. Harring- 

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

 legs, smoothness and sculpture of the abdomen, and the color of the 

 venter. 



^ Tribe IV. — Scelioninl • ^ 



A tribe allied to the Teleasini 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 extends 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 quite distinct; the postmargiual uervure, 

 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 Scelio).
