latero-triangular. The abdomen is peculiarly subquadrate and 

 obtuse. The species at hand are as follows: 



Under surface strongly but loosely punctate, the abdomen very finely and sparsely ; 

 prosternal lobe and adjoining short mesosternum abruptly very densely 



UnderSce as in the preceding/but with the prosternaHobe^oosely and strongly 

 punctate; prothorax strongly transverse, only very obsolete y subtubulate. 7 



Under surface throughout, excepting the propleura and mes-epimera, extremely 

 densely cribrate with moderate but very deep punctures, the abdomen

 para lei or very feebly convergent, just visibly arcuate, rapidly and briefly 

 rounded at apical third to the long subparallel tubulation which is about 

 three-fifths as wide as the base; punctures extremely fine and sparse through- 

 out with a rather more distinct single series along the base; elytra a fifth 

 longer than wide, a fourth or fifth wider than the prothorax and twice as 

 long, the sides only feebly oblique and slightly arcuate, the apex very rapid y

 smooth; pygidium vertical, small, transverse, similar in the sexes and densely 

 punctate; abdomen very obtuse at apex, shining, finely, sparsely punctate

 legs- beak finely, sparsely punctate and separated from the head by a deep 

 impression in both sexes, moderately slender, evenly arcuate, and as long^ as 

 the prothorax (tf), or feebly arcuate, more so and dorsally slightly turn d 

 at base and as long as the head and prothorax ( 9 ), the prothorax strongly 

 convex-vfewed in" profile, nearly a third (*) or two-fifths ( 9 ) wider than 

 long, the sides subparallel, rounding beyond the middle to the more moderate 

 subconic tubulation, which is half as wide as the base; surface very smooth 

 the remote punctulation barely traceable; elytra a fourth (£) to a fifth ( .9 ) 

 longer than wide, broadly oval, relatively somewhat less obtuse at tip than 

 in the preceding, distinctly wider than the prothorax and twice as long, the 

 grooves very fine, less sharply defined and shallower, but coarsely exarate 

 at apex suturally; small transverse pygidium shorter in the female, more 

 finely and sparsely punctate than in the preceding; abdomen nearly similar.
