 bands on the abdomen black. Head probably entirely black; the antennae 

 brownish yellow, darker basally. Basal joints of flagellum three or four times 

 as long as thick; the apical ones becoming transverse, twice as wide as long;

 Metanotum with the median 

 areola large and quadrate; 

 basal and middle lateral ones 

 separated. Abdomen stout, 

 the petiole narrow and rather
