coacavc to the very acute lateral angles tuid stnjjigly eoiuave 

 to the sharj) hind angles. The .scutellum is finely coriaceous. 

 The cli/tra are very glossy, except at the extreme outer margins, 

 with fine punctures in the inner anterior ])art. The rnentuin 

 is densely granular and ojjacjue. 



Variation of the male. Inconstant phase. In suiall specimens 

 the mandibles are not longer than the head, straight at the 

 inner edge and finely and evenly serrate from hase to a])ex. 

 In larger ones a basal grou]) of teeth is se})arated by a gaj) from 

 the rest. With increasing size the mandibles become longer, 

 the gap lengthens, the basal teeth become consolidated, and 

 the first and last of the terminal grouj) are larger than the rest. 

 In specimens of full size tlie mandibles arc about as long as the 

 head and the latter is very bioad. 



Constatit phtse. In tliis phase the mandibles are always 

 considerably longer than the head, whicli is not very broad, 

 and are compaiatively slendci". I'liey are curved, as in the 

 inconstant phase, have a broad basal tooth witii two or three 

 rounded cusps and are forked at the end, with one or two 

 minute teeth in the fork. The largest example of this phase 

 I have seen is slightly smaller than the largest of the inconstant 

 phase. The mandibles are rather more than double the length 

 of the head and the teeth between the pnmgs of the terminal 

 fork are reduced to slight vestiges. Males of both phases are 

 found together, but exam})les of the inconstant phase are 

 more numerous. I have seen no intermediates amongst the 

 large number I have examined. Of about 60 males, 12 are of 

 the constant phase.
