rather broad rufo-testaceous lines, the scutellum and post- 

 scutellum are yellow, suffused with rufous. Median 

 segment sharply oblique, the middle slightly hollowed ; 

 the sides broadly rufo-testaceous ; there are no keels 

 except the curved lateral ones, and on the apex the 

 testaceous part is bordered on the inner side by a lateral 

 keel. The propleurse above and beneath bordered with 

 yellow; obscurely striolated ; the mesopleurse black above, 

 bordered with rufous ; the middle broadly yellow, the 

 sternum rufous ; the base above finely longitudinally 

 striated, the rest punctured ; the metapleurse smooth, 

 shining ; a short, wide, deep, oblique furrow at the base 

 above. The coxae and trochanters are rufous, suffused 

 with yellow. Areolet narrowed at the top, being there 

 not much less in width than the space bounded by the 

 recurrent and the second transverse cubital nervures. 

 Abdomen uniformly ferruginous, shining ; the basal

 the ovipositor rufous, black at the apex ; the ventral
