 disk of the mesonotum and the base of the scutellum where the pubes-

 are brown, is entirely black. The head, except a tuft of ochraceous 

 pubescence on the face below the insertion of the antenna? and on the 

 vertex posteriorly, is clothed with a black pubescence ; thorax above 

 and at sides, dorsal abdominal segments i and 2, the venter and the 

 legs clothed with a rather long ochraceous pubescence ; dorsal abdom- 

 inal segments 2 to 7 with a black pubescence and in striking contrast 

 with the ochraceous pubescence of the basal segments. 



The head seen from in front is much longer than wide, the malar 

 space long, smooth and shining and fully as long as the pedicel and 

 first two joints of the flagellum united ; the clypeus, except anteriorly, 

 is punctate ; the labrum is feebly transversely impressed, sparsely punc- 

 tate, except the lateral hind angles, which are polished and impunctate ; 

 the first joint of the flagellum is shorter than the third but longer than
