Abdomen ovate, basal segment nearly equal in width to the second; remaining segments gradually tapering to the tip, and more deeply and densely punc- tured than the basal segments; first segments rounded at base without suture or carina, the apical margin confluent, with a large angular mark on each lateral margin, yellowish; apical margin of the second and third segments (broader on the second segment), yellow; that on the third somewhat tinged with ferru- ginous; remaining segments, above and beneath, dull ferruginous; beneath, the apical margins of the second an
