from the suture ; the pygidia are clearly not closely punc- 

 tured with microscopical points in the interspaces ; the pro- 

 sternum, lobe marginate and impunctate ; the mesosternum 

 is feebly sinuous anteriorly and tlie marginal stria is inter- 

 rupted in the middle j the anterior tibiae 3-dentate, apical 

 tooth very large., 



The above is similar to H. ohesus, Fahr., and otliers by the 

 thorax being bistriate laterally and the terminal tooth of the 

 anterior tibia being very large.

Oval, rather convex, black and shining; the head not 

 impressed, stria rather fine and complete, nearly straight 

 anteriorly; the thorax, marginal stria interrupted behind the 

 head, outer lateral wanting, inner well-marked, shortened at 

 the base, sinuous in the middle, and continued, but finely, 

 behind the head ; the elytra, stride, humeral both wanting, 

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

 rudimentary, sutural reaches just beyond the middle and is a 

 little shortened behind; the pygidia are clearly but not 

 closely punctate, the apex of the pygidium is smooth ; the 

 prosterimm, keel narrow between the coxte, anterior lobe some- 

 what pointed and marginate ; the mesosternum is evenly 

 arched anteriorly and the marginal stria is rather strong^ 

 crenate, arid parallel to the edge, and does not quite join the 

 jnetasternal lateral stria ; the anterior tibise are 3-dentate. 



The form of the mesosternum is an important character; it 

 is not truncate like that of Atholus corviiius, Germ., and I 

 have not included it in Thomson's genus.
