antennal segment, fourth to seventh antennal segments except a black 

 spot beneath at the apex of each, undersurf ace of club except two black 

 spots, line on humeri, posterior border of pronotum, tegulae, small 

 spot on angles of propodeum, legs beyond the femora and tips of these, 

 irregular subapical band of first, third, fourth, and fifth dorsal seg- 

 ments ; three subapical bands on second and sixth dorsal segments ; the 

 sixth and seventh antennal segments and club stained reddish ; wings 

 stained with yellow, the veins yellowish. 



Posterior ocelli removed from the eye by considerably less than 

 their diameter 's length ; emargination of the eyes broad, not triangular, 

 broadly rounded at apex ; front scarcely depressed beneath the median 

 ocellus, elevated into a weak median tubercle above the bases of the 

 antennae, its surface with separated punctures; clypeus moderately 

 convex, its surface weakly shining, rather obsoletely punctate ; labial 

 palpi with 2 segments, the first elongate, the second about one-half as 

 long. Fourth, fifth, and sixth segments of the antenna strongly wid- 

 ened at their apices, the seventh about as wide as long, the fourth and 

 fifth flattened beneath at their apices, the sixth and seventh flattened 

 beneath ; the club short, irregularly ovate, equal in length to segments 

 6 and 7, convex above, slightly hollowed beneath. 



Humeri rounded, pronotum laterally with well separated, rather 

 coarse punctures ; mesonotum anteriorly similarly punctate, more 

 closely punctured in the middle, posteriorly flattened but not de- 

 pressed and closely almost rugosely punctate ; scutellum closely punc- 

 tate, moderately convex, posterior angles of propodeum carinate but 

 not dentate ; pleura with well separated punctures. 



Anterior femur and tibia with regular surfaces, somewhat flattened 

 below, the tarsus not ciliate ; middle femur concave and ridged beneath 

 with a prominent tubercle near its apex; middle tibia with regular 

 surface, flattened beneath, as seen from in front gradually widened 

 from base to apex, two-thirds as long as the tarsus; metatarsus ap- 

 proximately equal to the remaining segments united ; the fourth seg- 

 ment about as long as broad ; hind tibia three-fifths as long as the 

 tarsus ; metatarsus equal to the remaining segments united ; fourth 

 segment slightly longer than broad. Radial cross-vein distant from 

 U^ by little less than the distance between M.^^^ and M. on the margins 

 of the cell R4+5. 



Punctuation of the abdomen fine and close ; the surface between the 

 processes of the last segment hardly truncate ; superior process blunt, 

 flattened, the inferior sharp, close together ; prominence of third ven- 

 tral segment with its summit anteriorly flattened. 



Exterior surface of squama with a patch of very short, incon- 

 spicuous setae, the inner surface glabrous except for a group of 15 

 or 20 stout spines and a less conspicuous group of 3 or 4 ; sagitta acute, 

 trigonal, the angles sharp; uncus rather long and slender, decurved 

 and slightly widened at apex, the tip mucronate. 



$. Colored as in the male, except that the face and clypeus are 

 black, with a triangular yellow spot between the antennae, the latter 

 are yellow to ferruginous with most of the club fuscous.
