116 NORTH AMEKICAN NYSSONIDAE (iIYMENOPTERa) 



at base of anterior tibiae merging into ferruginous at apc-x, and confluent with 

 .not on outer side basad of the middle, front of michlle tibiae, and spot on 

 outside basad of the middle, and spot on outer side of posterior tibiae basad 

 of the middle; the middle and hind femora are red except beneath; flagellum 

 yellowish ferruginous beneath. The wings are hyaline with a fuscous spot 

 occupying the marginal, second submarginal, upper and apical part of third 

 subinarginal cells, and extending vaguely down the second current vein, a 

 second spot in the apex of the second discoidal cell, and small spots around the 

 junction of the basal and submediar veins and at the apex of the median 

 cell Body clothed with short inconspicuous pubescence. Length, 9 mm. 



Inner margins of the eyes parallel, farther apart than the distance from 

 the front ocellus to the base of the antennae; clypeus strongly transverse, 

 convex, with a row of setiferous punctures, its edge margined; front polished 

 and impunctate as far up as the yellow intra-orbital lines extend, above 

 \vhich it is suddenly coarsely and closely punctate, with uneven surface; behind 

 the ocelli the vertex is sparsely punctate. Flagellum short, somewhat clavate, 

 the segments short, the first longer than the following. 



Mesonotum deeply but not densely punctate, mesopleura spar.scly but 

 strongly punctured; epicnemia impunctate, at right angles to the plane of 

 the mesopleura, from which they are separated by a sharp carina continuous 

 with that separating the mesosternum from the same; metapleura impunc- 

 tate, with a conspicuous pocket below; scutellum transverse, flat, sparsely 

 punctured, postscutellum convex and more closely punctate; triangular area 

 of propodeum with about eighteen slightly radiating strong carinae; posterior 

 surface rugose, the angles coarsely reticulate. Tarsal comb present, middle 

 and hind tibiae and tarsi spinose. 



First segment sessile, not coarctate, polished and nearly imininctate; 

 second dorsal segment with sparse shallow punctures, other segments less 

 sparsely punctate; ])ygidium strongly margined, longer than broad, longi- 

 tudinally striolate, the striolae anastomosing more or less. 



The rufous of the femora may give way to fuscous at base, and the apical 

 yellow spot on the hind femora may be in front instead of beneath, and be- 

 neath on the mid(de i)air instead of in front, or both beneath and in front 

 on the anterior pair.
