COLEOPTERA, FAM. LUCANIDAE. 179 



beyond the ante-apical one, and at the base of the man- 

 dibles this margin is strongly compressed so as to form a 

 sharp keel. The mandibles are opaque on the basal half 

 and become shining towards the apex ; in the opaque por- 

 tion distinct punctures are spread. 



The upper, side of the head bears a strongly curved 

 sharply raised keel, beginning opposite to the basal keel 

 of the mandibles ; it is narrowly interrupted on the middle 

 of the head; another much less distinct keel originates in 

 the lateral front angles of the head ; outside from this 

 keel the head is rugose and opaque, the rest of the head 

 is sub-shining, having an exceedingly fine sculpture and 

 a few indistinct punctures. The middle of the front mar- 

 gin of the head forms a broad projection which is trun- 

 cated anteriorly in a straight line which is tridentate; the 

 median tooth is erected and conical, the lateral ones are 

 minute. 



The sides of the prothorax are angular a little before 

 the middle, the angle forming a distinct tooth ; the front 

 margin is accompanied on both sides of the middle by a 

 curved impression; a very faint impression runs along the 

 middle of the disk. The middle of the disk is very shi- 

 ning, sparsely covered with distinct punctures ; the bronze 

 coloured lateral portions are opaque in consequence of a 

 very dense sculpture. The bronze coloured scutellum is 

 broader than long and rather densely covered with scale- 

 bearing punctures. 



The elytra are very shining, very finely, not densely, 

 punctured; the punctures across the base somewhat larger, 

 the shoulder-streak opaque. 



The under surface of the head and the sterna opaque, 

 sprinkled with small whitish scales; the abdomen and legs 

 finely punctured, each puncture bearing a small whitish 

 scale. The intercoxal part of the presternum is slightly 

 prolonged backward. 



The anterior tibiae are straight, slightly elongate and 

 provided on the outside, a little beyond the middle, with 

 a trace of a spine.
