BRUES: PARASITIC IIYMKNOITKKA. 



101 



Type.— No. 2349, M. C. Z., Florissant, Col. (No. 5339, S. H. 

 Scudder Coll.). There is also a second specimen, No. 2350 M. C. Z., 

 Florissant, Col. (No. 2509, Scudder Coll.) which is perhaps the same 

 species. The body of the type is seen in lateral view and is rather 

 well preserved. Of the wings only the radial cell and the second 

 cubital are preserved, but these serve to show characters peculiar to 

 this group.

 yellow or reddish. Antennae short, slender, involute, of nearly equal thick- 

 ness throughout, the joints near the base of the flagellum about one and one- 

 half times as long as thick, and those toward the tip a trifle shorter. Head

times as long as the abdomen. Wings hyaline, or slightly yellowish, stigma 

 and veins pale fuscous. Stigma very broad and short; marginal cell narrow, 

 the third section of the radius very slightly bent inward. Second cubital 

 cell of medium size, with a distinct upper side, which is, however, much shorter 

 than the first section of the radius. 



One specimen, collected by Mr. S. A. Rohwer at Station 13. Type 

 in the Amer. Mus. Nat. Hist., it is well preserved except for the basal 

 and posterior parts of the wings.
