 transverse ridge reduced to a raised but very distinct line ; pro- 

 thorax a little convex, slightly ampliate laterally in the anterior part, 

 not declivous at apex, and having a moderately deep median 

 impression from base to middle, and a smaller one in the anterior 

 part.

 shaped ridge connected with the basal part ; prothorax deeply 

 emarginate in front and with the angles very projecting, parallel 

 laterally, depressed, but with the sides of the anterior part sloping ; 

 it has in the middle a broad impression with carinate edges 

 narrowing to nearly half fhe size in the anterior part, and having 

 there a sub-lateral short, interrupted carina, as well as three 

 moderately broad impressions divided by ridges of very short, dense 

 setae ; elytra parallel, not covering quite the abdomen, plane with 

 the humeral callus very distinct, the three alternate intervals are 

 very distinctly carinate, and the striae have a duplicate series of 

 round conspicuous foveae divided l^y a narrow interval, the raised 

 costae are closely setulose ; pygidium with a longitudinal median 

 carina, and a transverse one ; metasternum sloping in front and 

 carinated from the apex to the median part, hollowed in the centre 

 and at base, and depressed laterally along the intermediate coxae ;
