iatercoxal process is long anJ narrow, but becomes broadiir in front, 

 so as to fit to the broad truncation of the metasternuin ; opposite the 

 medial angle of the latter there is a deep excavation. The intercoxal 

 part of this first segment is channelled in the same manner :is the 

 intercoxal parts of the pro- and niesosternum. The second, third, and 

 fourth segments are free and equal in length; fifth, a little longer, 

 triangular, rounded and hairy at tip, adapted to the triangular corneous 

 last dorsal, which is not divided so as to form an anal segment. 



I can see but two spiracles each side ; they are situated at the 

 anterior side angles of the second and third segments, the others are 

 concealed by the elytra. What can be seen of the dorsal segments 

 seems to be corneous, but I am not at liberty to relax the specimen to 

 make certain my observation. 



'i he elytra cover completely the dorsal segments, and are about as 

 long as the prothorax ; they are ovate, narrowed and acutely pmited 

 behind, convex above and coarsely rugosely punctured, in a peculiar 

 manner, which does not resemble the sculpture of any other Coleop- 

 teroii known to me. There are two faint dorsal costje on each, which 

 are obliterated, but tend to unite about one-sixth from the tip. and a 

 very faint trace of a third. Outside of these is a much stronger costa, 

 extending nearly to the tip, but united in front with the strongly re- 

 flexed but narrow side margin, which is obtusely angulated at the 

 point of junction. The epipleurse are well defined, and exteml to the 

 apex, at the base they are broader and concave, for the reception of 

 the knee of the middle legs. The side margin after uniting with the 

 lateral costa as above mentioned proceeds obliquely inwards to the 

 hind angle of the pronotutn, where it ceases; the base of the elytra 

 is declivous, and absukitely without i'old ; the scutelhim is triangular 

 and acute. 



Front coxae separated by the prosternun) ; globose, with a large 

 trochantin occupying the outer angle of the cavity. Middle coxa? 

 rounded, separated, prominent, without trochantin. Hind coxaj very 

 large, rounded, prominent, separated by the intercoxal process of the 

 first ventral segment. 



Legs stout, fossorial. Front thighs thick, unarmed ; tibiic with a 

 medial and apical digitation, and two terminal moveable spurs; tarsi 

 five jointed ; joints one to four triangular; first longer, the others dimin- 

 ishing in size, emarginate at tip. with the angles acutely prolonged ; 

 tilth as long as the two preceding, claws rather small, sinip](>; under 

 surface concave, hairy only at the sides. Middle legs just like the 

 front pair, except that they are somewhat longer.
