 to the inner eye margin; dorsulum and scutellum sculptured similar to 

 the head ; mesoplurne somewhat more coarsely sculptured: enclosure of 

 the metathorax smooth, shining, impunctate, except at the base, which 

 has short, longitudinal striae : the rest of the metathorax with small, 

 irregular punctures, median furrow deep ; petiole rather stout, a little 

 longer than half of the hind femora, above with rather large, irregular 

 punctures; legs and venation normal; abdomen smooth, shining; pygidial

 distinct separate punctures; no foveolate lines on the dorsulum, nor are 

 the lateral margins foveolate; mesopleurae with smaller punctures; meta- 

 thorax coarsely reticulate, the pleurae more finely so and anteriorly gran- 

 ular; legs and venation normal, the second cubital narrower than usual:
