with the hitoral margins very finely granular. The front 

 fihid is finely and sharply serrate externally and the middle 

 tibia bears a miiuite lateral s})ine. 



Variation of the male. In small specimens the sides of the 

 pronotum are slightly curved and the angulation is very blunt. 

 In larger males the sides are almost straight, the front angles 

 more ])roduced and the posterior angulation very strong. The 

 mandibles of small examples have the inner edge straight and 

 serrate almost from base to tip. In larger ones the terminal 

 part only is serrate, the first tooth stronger than those that 

 follow. In highly developed specimens this tooth (situated 

 about one-third from the tip) is sharp, immediately followed 

 by a few serrations, the terminal i)art of the mandible is smooth 

 and the extreme tip is forked. There is another small tooth 

 near the base internally. The mandibles of large specimens 

 are long and rather straight to the point of origin of the large 

 tooth and strongly curved from tliere to the tip. The head 

 has a sharp curvilinear anterior ridge, absent in small speci- 

 mens, and is a little hollowed in front of this.

^. Ratlier smooth and shining, with tlu^ head and pronotum 

 opaque, except the middle of the latter. The head is broad 

 and flat, the eyes large and rather prominent, the sides of the 

 head oblique before the eyes and contracted behind them. The 

 dypeal process is promineiit, transversely rectangular, straight 

 in front, with the angles rather sharp. The pronotum is very 

 sliort and broad, with a few fine ])unctures in the middle and 

 near the margins. The front angles are rounded and strongly 

 produced, tlie sides nearly straight and parallel, without lateral 

 angle, the liiiul angle blunt and the base very broad. The
