the tarsi have white down. The radial cellule is shorter than the stigma ; the radial 

 nervure is oblique at the base and apex, the apical turned-up portion having a short 

 branch ; at the top the second cubital cellule is about the length of the space bounded 

 by the first transverse cubital and the first recurrent nervures; the second recurrent 

 nervure is received shortly before the apical third of the cellule ; both the recurrent 

 nervures are bent — the first roundly, the second more acutely ; the transverse basal 

 nervure is interstitial.

Hal. Mexico, Northern Sonora (Morrison). 



Head deep black, the clypeus and mandibles testaceous, the tips of the latter piceous 

 and black; shining, impunctate, the top sparsely covered with long pale, soft hairs, 

 narrowed and rounded behind ; the furrow between the hinder ocelli deep and wide ; 

 the mandibles covered with long pale fulvous hair. The antennae reach beyond the apex 

 of the thorax, and taper slightly towards the tip, the apical joints curved ; the scape 

 covered with long pale fulvous hair ; the flagellum almost glabrous ; the third and fourth 

 joints subequal. The thorax shining, almost impunctate, sparsely covered with long pale 

 soft hair ; the lateral furrows on the mesonotum indistinct ; the scutellum is narrowed 

 towards the apex ; the median segment has a gradually rounded slope, shagreened in the 

 centre towards the apex, indistinctly furrowed down the middle at the base, the furrow 

 there margined and with an indistinct narrow keel. The propleurae are distinctly 

 punctured ; the mesopleurae are distinctly punctured, except at the base and apex , the 

 sternum is smooth and impunctate ; the metapleurse are impunctate, except at the apex, 

 where they are indistinctly punctured. The petiole is distinctly longer than the second 

 abdominal segment, punctured towards the apex, and sparsely covered with long pale 

 hair ; the basal third is narrowed beneath, in the middle it is broadly keeled, the sides 

 furrowed. The other dorsal segments shining, impunctate ; the terminal one broadly 

 and roundly keeled in the middle at the apex, the sides bearing large, deep, roundish 

 punctures. The ventral segments are more or less black, not punctured, and covered 

 sparsely with long fuscous hair. The legs are not very closely covered with long pale 

 soft hair ; the tibiae and tarsi have a paler more testaceous hue than the femora. The 

 wings do not reach the apex of the abdomen, and are clear hyaline, the nervures fuscous, 

 or fuscous-black at the base ; the transverse cubital and the recurrent nervures pale ; the 

 radial nervure shorter than the area bounded by the space between the base of the stigma 

 and the radial nervure, the basal abscissa of the radius oblique ; the appendicular 

 cellule is distinct, the upper nervure curved and pale in colour ; the first transverse 

 cubital nervure is curved at the bottom and is received quite close to the second, which 

 is a little curved, the third being still more curved; the first recurrent nervure is
