218 ON THE GENUS CEROBATES. 



Prothorax ovate , very broad and depressed , shining , 

 very smooth , the apical margin narrow, truncate , notched 

 at the sides. 



Elytra as long as twice the prothorax , broad , emarginate 

 at the base , the shoulders rounded ; margined and rounded 

 at the apex, tristriate along the sutural interstice at the base 

 and at the tip, bistriate in the middle, the Srd stria (exter- 

 nal) prolonged down to the tip ; the sides are punctured. 



Legs paler, femora compressed, tibiae very short, the 

 anterior ones deeply notched and toothed on the inner edge. 



Body beneath reddish brown , shining , slightly scaled at 

 the sides of' the prothorax and in the impressions ; head an- 

 gularly notched at the base, mesorostrum bifoveolate late- 

 rally, prosternum depressed , almost marginate on the sides , 

 metasternum and base of the abdomen depressed , the for- 

 mer channeled, apical segment of the latter impressed at 

 the sides and in the middle. 



Another specimen from the same locality differs in the 

 following characters: head slightly narrower, more depress- 

 ed , not foveolate between the eyes; rostrum shorter and 

 broader, more depressed, very obsoletely channeled when 

 viewed sideways ; prothorax broader at the apical margin , 

 truncate and less notched at the sides above , elytra 

 shorter and hardly wider; head and metarostrum explanate 

 beneath, the base of the former hairy; mesorostrum im- 

 pressed , with the margins raised ; metasternum with the 

 sides of the median channel oblique inwardly ; base of the 

 abdomen broadly excavated , apical segment with the 

 margin of the median foveola raised and hairy. These dif- 

 ferences are probably sexual , but I am uncertain whether 

 this specimen is a male or a female.
