BRUES: PARASITIC HYMEXOPTERA.

First segment longer than the

/ 



claviform, seen from the side almost petiolate. 

 slope of the metathorax, 

 finely longitudinally rugose; 

 with a pair of median and 

 lateral carinae which are con- 

 tinued less distinctly on the 

 second segment ; apex of ab- 

 domen rounded. Legs rather 

 long and slender, brownish. 

 Wings long and quite narrow; 

 stigma and veins light fus- 

 cous. Stigma elongate, 

 lanceolate, the radius arising 

 at its middle; radial cell 

 long, nearly attaining the 

 wing tip; submedian cell 

 considerably longer than the 

 median ; discoidal vein 

 broken below the middle; 

 recurrent nervure interstitial 

 with the first transverse cubi- 

 tus; first cubital cell rhom- 

 boidal, second elongate, its 



apex only one-half as long as its upper side and one-third as long as the 

 lower side. 



Type. — No. A40, in the collection of the Amer. Mus. Nat. Hist. 

 This species resembles a genuine braconine except for the long 

 submedian cell of the front wing.

Spathiinae. 



I think it is very probable that Ichneumon petrinus Scudder belongs 

 to this group. The very excellent figure given in his Tertiary Insects 

 (plate 5, fig. 14) shows the characteristic form of the body and peculiar 

 antennae of Hormiopterus and its allies, and I take it that the apparent 

 absence of the first section of the cubitus is an accident of preservation. 



STEPHANIDAE. 



Protostephanus Cockerell. 



There is one specimen, No. 5350, S. H. Scudder Coll., which may 

 belong to this genus or perhaps to Megischus. It is not well enough 

 preserved, however, to place definitely in either although I am assured 

 from its general habitus that it belongs to the Stephanidae.
