 and fringed with black and white hairs. Ventral segments two 

 and three, yellowish at apex, the third grooved indistinctly, 

 medially, the fourth with a deep median channel, the fifth carin- 

 ated. Wings dusky hyaline, broadly fuliginous at apex; the 

 stigma ferruginous, the veins fuscous. Head transverse, 

 scarcely as wide as the thorax, the frons closely punctate; 

 clvpeus smooth, slightly arcuated at apex; mandibles black, 

 with a longitudinal groove along the inner margin; thorax 

 and scutellum with rather coarse, rounded punctures, more 

 confluent anteriorly, but separated on the disk; metathorax 

 closely punctate. Last four joints of anterior tarsi and the last 

 joint of middle and hind tarsi, yellow. Abdomen twice as long 

 as head and thorax united, the first segment rather coarsely 

 punctate, but smooth and shining at the apical margin, and 

 clothed with sparse white hairs; the following segments, except 

 at margins, finelv, closely punctate, the surface of the bands 

 being smooth, polished, impunctate.
