notum narrowly, and an elongate lateral spot, large spot below tegulae, 

 tegulae, spot above, large spot in front of depression on mesonotum, 

 most of scutellum, angles of propodeum, dorsal and ventral (except 

 first) abdominal segments apically yellow; pronotum (except where 

 mentioned), band on scutellum, elongate spots on second, third, and 

 fourth segments rufous ; legs rufous ; wings dusky, especially near the 

 veins ; stigma and costa reddish brown, veins dark brown. 



Clypeus convex, broadly emarginate, very finely granular, with 

 large punctures intermingled ; front with large distinct punctures, 

 which are more widely separated on the eye margins and vertex ; hind 

 ocelli equidistant from the eyes and from each other ; scape short, third 

 segment of antenna as long as the three following. 



Pronotum with well separated large punctures; mesonotum with 

 punctures the size of those of pronotum, but closer and especially so 

 in the depressed area; mesopleura more closely punctured than the 

 mesonotum ; scutellum punctured like mesopleura, with an indistinct 

 carina medially. 



Second cubital cell on the radius as long as two-thirds of the dis- 

 tance between the recurrent veins. 



Abdomen with well separated, distinct punctures, which become 

 smaller posteriorly ; first dorsal segment slightly emarginate anteriorly 

 when seen from above ; second and third dorsal segments depressed 

 basally for about one-third their length ; apical ventral segments with 

 the large punctures well separated. Length, 12 mm.
