Variation of the male. In small specimens the frontal ridge 

 is not sharp, the clypcal jjroccss is branched on each side before 

 the end and the niandil)U"s are simple and slender, with a small 

 tooth before the ti[). Lai'ger examples liave a distinct clypeal 

 fork, the mandibles ari' f()ri<ed at the tip and there is a small 

 tooth near the middle. In lar^e specimens the clyjx'al fork is 

 long and narrow, tlie mantUbles are more strongly ronnded, tlie 

 middle tooth is strong and has minute teeth before and .after 

 it, the terminal fork is very divergent and the frontal ridge of 

 the head is elevated in tlie middle.

Type in the British Museum. 



The female .specimen described by Boileau as belonging to 

 this species, and labelled by him as a type, is quite different 

 from the actual female, of which a considerable scries was 

 collected by Mr. Malaise together with the males. It is a much 

 more smooth and shining insect, the pronotum has quite a 

 different sha])e and tlie front tibia is short, without produced 

 termmal fork. Being immature and deformed it must remain 

 nameless.

Chocolate -brown, the female nearly black, clothed with yellow 

 hair, sparsely above and closely beneath. The club of tlie 

 antenna consists of four ecpially long joints and the preceding 

 one is not produced. The ])rosternuni very short and rounded 

 behind. 



$. Very dark brown or black, rather shining above. The 

 head is coarsely rugose, with fairly shar]) front angles. The 

 pronotum is finely and closely punctured in the middle and 

 rugosely at the sides, 'i'lie front angles are blunt, the sides 

 well rounded to the ratliei- sharj) lateral angles, nearly straight 

 from there to the similarly well-marked hind angles. The 

 scutellum is closely punctured and clothed with hair. The 

 elytra are finely and very closely punctured and shining but 

 rather less so at the sides and apices, which are densely 

 punctured. 



^. Rather short and compact. The femora and tibiae are in 

 part bright orange or red. The head and pronotum are dull, 

 the head flat above, densely granulai-, surrounded by a ridge
