De!«cription of a 9few Genus and Five Kew Species of 



ACULEATE HY.^IEXOPTERA from the Santa 



Fe mountains, New Mexico. 



BY P. CAMEfeON.

PARAiVASARIS gen. nov. 



Radial cellule with a distinct cellule at its apex, elongate, reach- 

 ing to the apex of the wing ; three closed cubital cellules, the 2nd 

 and 3rd receiving each a recurrent nervure. Autenu?e short, cla- 

 vate, becoming gradually thickened from the fifth joint to the base 

 of the last. Eyes reaching close to the base of the mandibles. 

 Occiput sharply margined. Petiole elongate, as long as the rest of 

 the abdomen, stout, the basal third narrower than the middle; the 

 extreme apex distinctly narrowed, forming a short neck. Second 

 abdominal segment bell shaped, longer than the petiole. Mandibles 

 short, not toothed at the apex. The occiput is transver.'-e behind ; 

 the space behind the eyes is moderate; the eyes slightly converge 

 below ; the prothorax is large ; the apex of the tegulse extends 

 beyond the base of the scutellum, w hich is flat and is slightly nar- 

 rowed towards the apex, where there is a wide transverse furrow ; 

 the post-scutellum is not clearly separated from the metanotum. 

 The alar stigma is distinct ; the transverse basal nervure is inter- 

 stitial ; in the hind wings the radial cubital and discoidal nervures 

 extend to the apex of the wings, and the transverse cubital nervure 

 is distinct ; the anal nervure is distinct but short, it not extending 

 beyond the transverse median nervure, which is straight and oblique 

 and does not reach to the middle of the wing; the submedian cellule 

 thus formed is wide ; the anal cellule is open at the apex, through 

 the shortness of the anal nervure. The clypeus is large, convex, 

 its apex is transvei'se, with the sides obliquely narrowed ; at the 

 base of the scutellum, behind the transverse groove separating it 

 from the mesonotum, is a row of large fovea? ; the inner spur of 

 the tibiiB is much larger and broader than the outer one ; there is a 

 short blunt tooth or dilatation on the base of the claw. 



The principal characteristics of this genus — the sliort dilated an- 

 tennae and the presence of two spurs on the middle tibiae — refer it 

 to the Masaridse if anywhere, as the two spurs on the middle tibiae
