to the tip. The head is vertically einarginatc in fVonl, with a 

 rather sliarp hut not raised u])per ed<i;e. Katlici- larj^cr speci- 

 mens hiivv longer, gently eiirved mandihles, with three well- 

 marked detached teeth, a small basal one, a f-iiily long one not 

 far from the last and a third not far from the middle. Neither 

 these teeth nor the smaller ones at the eiul are s3'm metrically 

 placed. 



Constant phase. The head is very l)road and its front edge 

 strongly elevated. The mandibles are slender, strongly curved 

 and symmetrically toothed. The basal tooth is very small, the 

 next flat and oblicpu^ly truncate, the third is placed well beyond 

 the middle and is l)ilobed. Another rather shar[) tooth is de- 

 veloped not far fi-om the tij), followed by one or two minute ones.

The Southern C. delesserti has so close a resemblance to the 

 Northern C. awera that at first sight they appear alike but 

 careful examination reveals numerous sliglit diflFerences. The 

 outline is not ((uite the same, the elytra l)eing rather kmger and 

 naiTower in the present s})ecies. The pattern is also a little 

 ditterent. Tlie black sutui-al patch has rather more curvilinear 

 sides, owing to its being broadei- at the base and more tapered 

 behind. In the male the elytral e])ipleur?e are not pale, as in 

 C. cuvera, the head is more gramdar and opaque and, in well- 

 developed specimens, the basal tooth of the mandible is 

 situated farther back and followed by an additional and 

 broader process. The constant i)hase of the male ai)])ears to 

 ])redominate over the inconstant })lia.se in this species. Exam- 

 l)les of the latter seem to be fewer in mnnber and those of the 

 constant phase vary to some extent in size, although not in the 

 form of the mandible.
