tliough not so intense a one in the apical portion of the first discoidal cell ; fol- 

 lowing parts yellow: prouotuui, tubercles, a somewhat cuneate mark along the 

 upper margin of the mesopleura, posterior two-thirds of scutel, a spot on each 

 side of mesonotum, anterior and middle femora and tibiae, the former apically, 

 the latter in front, the greater part of the front and posterior femora, as well as 

 a stripe on the posterior aspect of femora and the greater part of the anterior 

 and middle tarsi ; posterior tarsi brown. 



Abdomen. — Strongly punctured, with its punctures well separated, the apical 

 dorsal segment apparently without a pygidial area; an ajjical margin on each of 

 tiie dorsal segments, excepting the apical one, yellow.

9 • — 8 mm. — Head. — Cheeks not margined posteriorly but punctured, with the 

 punctures well separated and deej). sculpture of front hidden by appressed pu- 

 bescence somewhat tuberculate between the insertion of the antennse, clypeus 

 rather closely and distinctly punctured and depressed along the apical margin, 

 the apical half of the antennae much thicker than the basal half, the apical joint 

 forming sort of a truncated cornucopia, seen from below this latter joint looks 

 like the apical joint of the antennae in a male Odynerus, i. e. as if there existed a 

 hook tlexed upon the joint proper, part of the scape and pedicel reddish-brown, 

 flagel dark brown to blackish, mandibles dark brown at base and apex, yellow in 

 l)etween, front pubescent like side of metanotum. 



Thorax. — Dorsulum apparently rugoso-punctate like the scutel, which latter is 

 apparently without a mai'gin laterally, mesopleura coarsely punctured, but not 

 so coarsely as the dorsulum; metathorax with a strong spine on each side, the 

 enclosui'e rather protuberant and not well defined, longitudinally striate, some 

 short spines on the posterior aspect of hind tibite; wings transparent, with a 

 brownish tinge ; the nervures and stigma blackish, petiole of the second subinai- 

 ginal cell, and the cell itself about as long as the cell is high, pronotum with a 

 yellow line on each side nearly forming a continuous band, tubercles partly 

 yellowish, tips of metathoracic spines yellowish, coxae brownish to blackish, rest 

 of legs mostly ferruginous, tarsi and tibiae partly brown, side of metanotum and 

 postscutel witli a more or less dense, conspicuous, appressed pubescence. 



Abdomen. — Distinctly closely punctured, the dorsal apical segment bidentate, 

 with a slight elevation between the teeth, a yellow border at apex of first and 

 second dorsal, second, third, fourth and fifth ventral segments; the third, fourth, 

 fifth and sixth dorsal segments with an elongate yellow mark on each side, 

 nearly forming a continuous border, greater part of the basal half of the first 

 dorsal segment pubescent in much the same way as the sides of the metanotum. 



Type. — University of Kansas. 



Type locality. — Bill William's Fork, Arizona.
