Very convex; of a pitchy colour. Antenna3 with the three 

 basal joints yellow, the rest infxiscated; they are ratlier 

 long and slender, a little incrassated towards the extremity ; 

 3rd joint scarcely so long as the 2nd; 4th considerably 

 shorter than the 3rd; 4 — 10 differing but little in length, 

 but the apical ones evidently stouter than the others; 11th 

 joint rather stout, longer than the lOtli, its extremity 

 paler. Head pitchy-black, the parts of the mouth and 

 palpi yellowish. Thorax pitchy in colour, a little paler at 

 the sides, very much naiTOwed to the front; the base dis- 

 tinctly sinuate on each side, and the posterior angles 

 projecting backwards, their extremity rounded. Elytra 

 longer than the thorax, but aboiit as broad, their sides 

 gently ciu'ved, e^^dently narrowed to their outer hind

 punctured. Hind body, when extended, very much 

 narrowed to the extremity, pitchy in colour, its punctua-

In the male the dorsal plate of the 7th segment of the 

 hind body ends in four spines, of which the two middle 

 ones are closer to one another than to those at the sides, 

 and are more slender and project farther backwards; the 

 lateral notch on each side extends a good deal farther 

 forwards than does the middle one; the ventral plate of 

 the same segment bears at the extremity a deep and ex- 

 tremely broad triangular excision.

In the female the dorsal plate of the 7 th segment of 

 the hind body terminates in four elongate, almost equi- 

 distant spines, the two in the middle being distinctly 

 more slender, but scarcely longer than the lateral ; the 

 ventral plate also ends in four spines, of which the two 

 in the middle are rather stouter than the lateral, and
