is not margined apically ; the mesosternum is straight and 

 clearly mavginatc; the anterior tibiaa arc 3-dentate. 



This species is larger than adject us, Mars., but it is very 

 similar in outline.

 stria antice siuuato ; elytria atriia tenuiter imprcssis vel obsolct is ;

Oval, rather convex, opaque, and black, densely and 

 rugosely punctate above, the frontal stria is fine but very 

 distinct and feebly sinuous in front ; the thorax, the marginal 

 stria is very fine and close to the edge, and continues so 

 behind the head, behind the head there is a second fine stria 

 ending on each side behind the eyes and leaving a very 

 narrow interstice, from the basal angle along one half of the 

 thorax is a fine carinate stria close to the edge, in front of 

 the scutellum there is a short linear smooth space, not very 

 conspicuous; the elytra, the dorsal striaj are very fine, the 

 latcial margin is finely carinate (this may represent the outer 

 humeral stria), the inner humeral is complete and bent behind 

 the base, 1-2 complete, 3 slightly shortened at the base, 4-5 

 almost obliterated, also the sutural ; the pygidia are more 

 coarsely sculptured than the thorax and the sculpture is some- 

 what reticulate ; the prosternum, the keel is narrowed 

 before the coxa? and has a marginal stria ; the mesosternum 

 is feebly emarginate, stria complete ; the underside is more 

 or less punctulate ; the anterior tibia? are robust and strongly 

 3-dentate. 



The dorsal stria? of this species somewhat resemble those 

 of II. semigranosus, Mars., but there is no known species 

 similar to it. It will be figured shortly.
