remaining three very small; on the inner surface of the 

 mandible beginning- at the second tooth is a subapical row 

 of bristles. Thorax opaque, with sparse and rather large 

 piliferous punctures ; pronotum nearly twice as long as the 

 mesonotum, narrowed anteriorly ; mesonotum with two well- 

 defined parapsidal furrows ; scutellum with a deep transverse 

 groove at the base. Median segment about half as broad 

 again as long, margined laterally and at the apex, finely and 

 closely transversely striolate ; the enclosed median space 

 twice as broad at the base as at the apex, with five strong 

 longitudinal carinae, the space between the carin^e with low 

 transverse strise forming reticulations ; sides of the segment 

 very finely obliquely striolate ; the surface of the posterior 

 truncation subconcave, finely aciculate, with a median longi- 

 tudinal carina. Abdomen smooth and shining, with a few 

 scattered punctures on the third and fourth dorsal segments. 

 Hind tarsal ungues (fig. 1, d) strongly bent, produced at the 

 base into a strong tooth-like lobe ; with one tooth which 

 rises at right angles ; the apical tooth very long and acute, 

 about twice as long as its basal breadth ; on the external 

 surface of the ungues are three bristles — one on tlie dorsal 

 edge above the base of the median tooth, a second sub- 

 ventrally on the basal projection, and a third between the 

 two. Submedian cell longer than the median; radius at
