strong apical carina of propodeum. From a great majority of the 

 species they differ also in habitus, the abdomen being unusually short 

 and the hind legs unusually long. All three are ferruginous with 

 fasciate mngs. 



Female. — Length 10 mm. 



Head thin, temples very strongly receding and nearly fiat, occiput 

 shallowh" concave; frons coarsely and densely punctate, medially im- 

 pressed, a high carina between antennae; face densely punctate, im- 

 pressed on each side and rather prominent medially; clypeus barely 

 half as broad as face, strongly rounded and narrowly inflexed at apex, 

 the basal portion rather densely and finely punctate; cheeks in front 

 view straight, their extended angle slightly acute; malar space as 

 long as basal width of mandible; mouth distinctly narrower than face, 

 mandible nearly as broad at base as long, strongly narrowing toward 

 apex; junction of occipital and hypostomal carinae distant from base 

 of mandible by the width of the mandible; eyes slightly longer than 

 width of face, subparallel, inner margins weakly concavely curved; 

 diameter of a lateral ocellus much more than half postocellar line, 

 latter equal to ocellocular line; antennae (incomplete) very slender, 

 second joint of llagellum about three times as long as thick. 



Thorax densely, coarsely punctate throughout; notauli weakly 

 broadly impressed; scutellum elongate subtriangular, lateral areas 

 more sparsely punctate; propodeum rather flat, punctured like thorax, 

 with a short, strongly defined, impunctate petiolar area, pleural 

 carina more or less distinct posteriorly, spiracles small, barely twice 

 as long as broad. 



Legs ver}^ slender; hind leg nearly twice as long as body, femur 

 reaching fully half its length beyond abdomen, inner calcarium hardly 

 reaching middle of basitarsus. 



Wings: Radial cell very narrow, apical abscissa of radius weakly 

 curved at base, twice as long as basal abscissa; areolet smaller than 

 usual, with long petiole, second intercubitus strongly curved, recurrent 

 distinctly before middle; second discoidal cell very short, second re- 

 current nearly as long as basal abscissa of subdiscoideus and weakly 

 curved ; nervulus strongly postfurcal ; abscissula not much longer than 

 intercubitella. 



Abdomen barely longer than head and thorax, polished; first 

 segment depressed, more than half as broad at apex as long, petiole 

 much broader than thick; second tergite slightly longer than broad 

 at base; segments beyond third strongly compressed; ovipositor 

 short, straight, sheath barely half as long as first tergite, elongate 

 oval. 



Ferruginous; face, orbits, and lower part of head paler, orbits 

 yellowish; narrow circles about ocelli and spots on occiput, prepectus, 

 and metasternum black; hind tibia reddish piceous, base yellow;
