Long. 13 mm.; terebrae long. 10 mm, 



? . Head massive, very deeply and rather narrowly eniar- 

 ginate posteriorly, shining and almost smooth, the front 

 minutely punctured ; clypeus with a small tooth in the 

 middle of the anterior margin. Antennae stout, the second 

 joint twice as long as broad, the fourth about one-third 

 longer than the third. Prothorax with a small tooth on 

 each side beneath, the thorax somewhat overhanging the 

 anterior truncation ; prtescutum strongly transversely stri- 

 ated, longitudinally depressed in the middle ; scutellum, 

 median segment, and pleurae very coarsely reticulate ; hind 

 coxre transversely striated ; tarsal ungues with a comb of 

 six teeth in addition to the apical point. Abdomen some- 

 what compressed laterally ; the first segment petiolate, 

 broadened at the apex, and longer than the rest of the abdo- 

 men ; the apical segments sparsely clothed with cinereous 

 pubescence. Second transverse cubital nervure incomplete, 

 indicated by a scar in the middle ; second cubital cell 

 receiving both recurrent nervurcs, the first close to the 

 base, the second just before three-quarters from the base. 

 The dark transverse band from the stigma is very broad, 

 occupying the whole of the second cubital and second dis- 

 coidal cells, also the apical half of the first cubital and the 

 basal portion of the radial cell, but the extent of the band 

 may be variable.

 of teeth in the ungues, and the position of the first recurrent 

 nervure.
