f oveolate ; mesopleuron polished, its upper groove widened, and coarse- 

 ly partitioned, lower groove finely f oveolate, posterior groove coarsely 

 foveate; metapleuron rugose, anterior triangular portion mostly 

 smooth ; propodeum rugose, carinae rather prominent, the areas well 

 defined, costulae distinct, spiracle ovate. First abscissa of radius 

 longer than that of basal vein ; third and fourth abscissae of cubitus 

 about equal; recurrent vein slightly longer than the second abscissa 

 of cubitus; nervulus postf ureal by half its length; first and second 

 abscissae of submedius about equal; interanal vein represented by a 

 short stump continued by a pigmented line. Forefemur fringed with 

 long pubescence ventrally ; hind tibia broadened at apex but not ex- 

 panded into a flaring process ; inner spur of middle tibia a little more 

 than half as long as the basitarsus, second and fifth tarsal segments 

 about equal ; imier spur of hind tibia slightly more than half as long 

 as basitarsus, basitarsus about as long as the next three tarsal seg- 

 ments combined, second tarsal segment longer than fifth ; hind tarsal 

 claws pectinate. First abdominal suture slightly curved to the mar- 

 gin ; second tergite shorter than third medially. 



Type.—U.S.^M. No. 2170. 



Redescribed from the type, from Los Angeles, Calif., and a paratype 

 male, San Bernardino County, Calif., the only known specimens.

 dibles and ocellar area black ; wings fuliginous, costa and stigma fer-

 little flaring, not notched ; temple wider than the eye in dorsal view ; 

 malar furrow about 0.67 as long as basal width of mandible; galea 

 moderate, but considerably shorter than long axis of eye. Lateral 

 face of pronotum smooth and shining except in the median longi- 

 tudinal groove, median lobe of mesoscutum with an indistinct median 

 longitudinal elevation; notaulices f oveolate; mesopleuron polished, its 

 upper groove coarsely foveolate, its lower groove straight, foveolate, 

 posterior groove foveate ; metapleuron mostly smooth ; propodeum ru- 

 gose, carinae moderately high, costulae distinct, spiracle long ovate. 

 First abscissa of radius longer than that of basal vein ; third abscissa of 

 cubitus slightly longer than fourth ; recurrent vein longer than second
