184 LUCANID^. 



Tlie head and pronotum are strongly punctured and not 

 opaque ; the sides of the latter are slightly convergent, the 

 front angles rounded ; the el^i^ral intervals are narrow and 

 distinctly punctured. The tooth behind the eye is feeble, the 

 mandible short and triangular, but with the tip acutely 

 produced. In larger specimens the median depression alone 

 of the pronotum is strongly punctured, the sides, as well as the 

 head, are more finely punctured and opaque, and the el}i:ral 

 intervals are scantily punctured. The mandibles are more 

 slender and a little produced at the base internally. Large 

 specimens have the elytral intervals very minutely punctured, 

 the head and jironotum entirely opaque and lightly punctured. 

 The front angles of the thorax are truncate. The mandibles 

 are about twice as long as the head and in addition to the basal 

 tooth there is a second tooth above and a little in front of it.
