This is a bright flavous species Mith the mandibular apices, 

 interocellar space contiguous with occiput below, flagellum, three 

 ^esonotal vitt« (the external ones confluent at the scutellar fovea), 

 two basal metanotal spots, variable small meso- and sometimes 

 meta-pl<nn-al marks, discal and lateral and ventral apices of 

 abdominal segments, and the hind legs with coxaland troehanteral 

 spots, base and apex of tibise, external lines on femora and most 

 of their tarsi, black. 



I have seen three specimens, representhig both sexes, of this 

 species.
