face mark along the eye margin between the clypeus and the beginning of the 

 lower side of the emargination of the eye, and a stripe on the scape anteriorly. 



Thorax. — With pubescence like on the head, mostly closely punctured in much 

 the same way as the face, metathorax distinctly concave and bounded by a salient 

 margin, wliich is produced into a rather acute angle near the middle of each side 

 of the outermost edge of the basin of the metathorax, this basin striate and uni- 

 formly dullish, following parts yellow : anterior and posterior maigins of prono- 

 tum, a spot on each side of scntel, post scutel and the lateral margins of the pos- 

 terior face of the metatliorax ; wings brownish, with a yellowish cast, the mar- 

 ginal cell distinctly iufuscated. 



Abdomen. — Dullish and finely sculptured, except for the scattered indistinct 

 pit-like punctures, apical margin of second, third, fourth and fifth dorsal seg- 

 ments very coarsely, deeply and closely punctured, ventral surface similarly 

 sculptured to the dorsal surface, but with the pit-like puu.ctures represented by 

 distinct strong punctures, and the margin of the second, third, fourth and fifth 

 segments much narrower and not so coarsely punctured, the following yellow: a 

 band at apex of each of the dorsal segments, the second, third, fourth and fifth 

 ventral segments and the sixth ventral n)ostly, the latter tinged with brown and 

 partly brown the same as the corresponding dorsal segment, which latter is an 

 exception to the statement made for the dorsal segments in that the brown color 

 extends from base to apex along the middle portion.

Similar to anormis, from which it can be separated at a glace by 

 the predominating brownish ferruginous color. From the descrip-

 brownish ferruginous in color, excepting the eyes, ocelli, luteous 

 ornaments and black of abdomen. 



9. — 7 mm. — Head. — With luteous ornaments as follows: base of mandibles, 

 basal half of clypeus, a somewhat V-shaped large mark ou the front extending 

 down to between the insertion of the antennae and occupying that part of the 

 face which fills the emargination of the eye and stripe adjoining the upper half 

 of the posterior margin of the eye. 



Thorax. — Luteous, as follows: gieater part of the anterior half of pronotum, 

 with the exception of a narrow interiuption along the middle line, a spot on the 

 dorsulum near the scutel, tips of anterior and middle femora and a mark and 

 stripe on each tibia; wings transparent, somewhat smoky, with the apex of the 

 marginal ceil infuscated. 



Abdomen. — The edge of the second segment not conspic^uously different in 

 punctuation from the remainder of the segment, greater part of second, third, 

 fourth, fifth and sixth segment blackish, the following luteous: posterior third 

 of first dorsal with its lateral prolongation extending to a little before the middle 

 of the segment along the lateral margin, a circular spot on each side of the second
