 the lateral margin are blackish spots, increasing posteriorly. The whitish 

 margins expand medially into a row of very small triangles. Venter

This species is the size of astidus. O. S., but the latter has darker 

 antennae, the frontal callosity black, a more perceptible cloud on the 

 divarication of the third vein, and the median row of abdominal spots 

 much larger. The abdomea appears more tapering and the rufous tinge 

 is wanting.
