 dullish, reticulate, pygidium blackish, slightly convex, with a lateral 

 impressed line on each side near the base, smooth and apparently 

 finely sculptured.

Female. — Length 9 mm.; head black, its pubescence ochreous 

 except along the lower edge of the labrum where it is brownish, fovea 

 with pale ochreous pubescence, a little more than two-thirds as wide 

 along the ocellocular line as the latter is long, narrowly separated 

 from the eye margin where the ocellocular line joins the latter, fovea 

 deep its boundary along the front almost vertical, fovarea rather 

 well developed, punctured, angulate at a point nearly half way 

 between the anterior ocellus and the antennal line, fovea extending 

 distinctly below the antennal line but apparently falling short of 

 the clypeal line, clypearea wanting, clypeal punctures distinct, 

 adjoining or almost adjoining all over, clypeus convex, polished, 

 apparently not at all reticulate, mandibles black, reddish castaneous 

 near the middle and at apex, palpi typical, joint 3 of 

 antennae : 4 + 5 : : 4 : 5, antenna? blackish brown, labrarea truncate,

 stigma pale brownish stramineous, subcosta blackish brown, border 

 of stigma and remaining veins brownish stramineous, darker than
