is one-third the length of the body, minutely punctate and scabrous, taper- 

 ing only a little in its basal and considerably in its anterior half, the fi'ont 

 well rounded. The elytra are about two and a half times longer than 

 broad, equal on the basal two-thirds, and then rounding rapidly inward, so 

 that the posterior outline of the body is more broadly rounded than the 

 anterior outline ; the elytra are profusely punctate with little pits, averag- 

 ing scarcely more than 0.02""" in diameter, distributed at pretty regular 

 intervals, but not forming anything like longitudinal series, and so near 

 together as to be equivalent to about fourteen rows. The whole body is 

 uniformly black.

A single elytron, with its reverse, is very poorly preserved, more than 

 twice and a half as long as broad, equal until near the tip, which is rounded 

 off; it is traversed by eight or nine very slightly impressed and delicate 

 punctate striae O.!""" apart.

Three specimens were obtained of this species, all of them elytra. 

 One shows the two elytra crossed at the base, and a reverse of this shows 

 the cast of the upper surface ; the other two are single and perfect elytra, 

 both exhibiting the upper surface, one in relief, the other as a cast, but 

 they are not i-everses. This and the two following species classed under
