the ocelloccipital distance; anterior ocellus closer to apices of antennal 

 tubercles than to occiput; head beneath with rounded posterolateral 

 angles; distance between occipital and hypostomal carinae subequal 

 to length of hypostomal area. 



Anterior margin of pronotal disk strongly ridged, the anterior half 

 with coarse, confluent to subconfluent punctures, arranged in longi- 

 tudinal rows; scutum with subconfluent, coarse punctures except 

 posteriorly somewhat more crowded; scutellum with punctures 

 slightly more separated; mesopleural disk produced anteriorly in 

 middle beyond concave anterior face of sclerite, the punctures 

 about as in shuckardi; punctures small on areas adjacent to cuneate 

 space on propodeum, the disk posteriorly and laterally with larger, 

 subconfluent pits; posterior surface of propodeum with mostly con- 

 fluent or subconfluent pits. 



Disk of first tergum strongly ridged anteriorly; last tergum sha- 

 greened at apex. 



Inferior margin of hind femur obtusely angulate at middle; apex 

 of hind tibia on inner surface without heavy, flattened, short setae. 



Male. — Length 12-17, forewing 7-12 mm. Color as in female except 

 that venter of head occasionally is all black and as many as six flagellar 

 segments may be red. 



Clypeal keel strong, present on basal two-thirds or three-fourths; 

 median lobe of clypeus with a shallow emargination separating the 

 two well-developed teeth; distance from apex of frontal platform to 

 occiput 0.85-0.87 times the width across eyes; front with mostly 

 contiguous to subcontiguous pits; vertex with smaller, more scattered 

 punctures; ocellocular distance 1.9-2.8 times the postocellar distance, 

 and 0.59-0.71 times the ocelloccipital distance; occipital carina weak 

 or evanescent dorsally; median flagellar segments 1.4-1.5 times as 

 long as wide. 



Pronotal disk anteriorly with a strong ridge, behind that with 

 weak to strong punctures, sometimes rather scattered, sometimes 

 arranged almost contiguously in a few transverse rows; scutum and 

 scutellum with coarse, shallow, contiguous to subcontiguous pits; 

 mesopleural disk with very coarse, contiguous to scattered pits; ineta- 

 pleuron usually without ridges above, but occasionally with a few 

 weak ridges; propodeal dorsum irregularly rugulose, the narrow 

 median channel with a few transverse rugae, the posterior margin 

 strongly ridged; lateral surface with a few strong rugae anteriorly, 

 the rest of surface with coarse contiguous pits or irregularly rugulose; 

 posterior surface varying from contiguously pitted to irregularly 

 rugulose. 



First tergum with strong transverse ridge anteriorly, the disk with 

 scattered large punctures; sterna 3-5 with short, erect vestiture, a
