widened posteriorly, apex moderately rounded ; base somewhat 

 deeply emarginate, humeral angles projecting forwards, nodu- 

 liform, basal end of third interstice also projecting forwards, 

 less strongly noduliform. Disc with rows of small closely-set 

 shallow punctures each subtended by a small granule; third 

 and fifth interstices more prominent than the others, sutural 

 with five granules, second with three or four small tubercles 

 spaced out on interstice, third and fifth each with row of 

 small closely-placed tubercles from base to middle, thence with 

 a few isolated tubercles extending down declivity, fourth with 

 three tubercles similar to second, sixth with row of about eight 

 regularly and closely placed. Beneath gently convex; fifth 

 with small transversely oval foveiform depression at extreme 

 apex.

Of this distinct species I have five specimens under exam- 

 ination, all apparently of the one sex and probably females. 

 I have not hesitated to describe it, as it is a thoroughly 

 distinct species. In general appearance it somewhat resembles 

 Sclerorinus horridus, and I long had a specimen under that 

 name. In Blackburn's collection there is a specimen named 

 S. parvulus. It is, however, certainly not a Sclerorinus, and 

 though tentatively placed in Talaurinus probably requires a 

 new genus. I have selected a specific name in accordance with 

 a superficial resemblance to Bubaris pubescens. There is a 

 strong connection between this species and T. scaber, Boisd. ; 

 the rostrum in the latter species is rather longer and has the 

 internal ridges raised at base, but is very similar in appear- 

 ance, the shape of the thorax is practically the same, the 

 elytral tubercles, however, are different. 



Type in author's collection. 



Talaurinus spiniger, n. sp. 



9 . Of moderate size, robust. Black, with feeble muddy 

 clothing; setse small, black; no median ventral vitta. 



Head convex, broad, with two impressions in front con- 

 tinuous with sublateral rostral sulci. Rostrum short, width 

 across external ridges considerably less than width across 

 sides, external ridges somewhat convergent to base, internal 

 ridges subobsolete, only indicated by the position of the sub- 

 lateral sulci, these obliquely set, deep, foveiform at base, 

 becoming shallower anteriorly, median area gently and evenly 

 concave. Scrobes short, somewhat curved, ending distant from 

 eye. Eyes small, round. Scape of moderate length, not much
