 Above these in an oblique line are three or four much shorter 

 ones. Labial palpus reaching to the apex of the fore coxa. A 

 series of small setae along the posterior margin of the antennal 

 groove. Postantennal region armed with a stout bristle and two 

 or three small ones in addition to the marginal row of about six 

 bristles (Plate XV, fig. 77) . Pronotum armed with a single row 

 of alternating weak and strong bristles. Meso- and metanotum 

 each armed with two rows of bristles. Each abdominal tergite 

 similarly armed. Metanotum and anterior four abdominal ter- 

 gites with one or two stout dorsal teeth on a side. Modified 

 segments: Process of the clasper more or less triangular but 

 sclerotized in such a way as to give the appearance of being 

 very slender in the middle region and widened distally.

 spiniforms, one long bristle, and one or two shorter ones (Plate
