Tfipe, in the British Museum. 



Tlie habitat of the male specimen, the only one yet described, 

 is not kno^v^l. The female specimens described by Boileau 

 were supposed to have been brought from Assam, but this does 

 not appear to be certain. The locality given above is that of 

 two females in the British Museum. A similar female was 

 described by Gravely in error as belonging to the form to which 

 he gave the name Cladoijimthus arroivi. It is rather surprising 

 that the very large and striking male of the species should be 

 apparently rarer tiian the female. The head and mandibles of 

 this remarkable insect show an evident relationship to species 

 of the genus Hexarthrius, from which it is excluded by the 

 three-jointed club of the antemia. The antemia? of the type- 

 specimen are incorrectly drawn in the figures given by Parry.

Brick-red, with tlie head and pronotum usually darker than 

 the elytra and lower siu'face, the antemitse, tarsi and extreme 

 edges of head, thorax and elytra ahnost black ; elongate and 

 moderately convex, with slender legs. The prosternum 

 strongly compressed and a little produced behind. The 

 shoulders of the elytra acutely angular. 



$. The upper surface is shining, the head dark in the region 

 of the eye and the clytral suture rather more conspicuously 

 dark than in the male. The head is coarsely rugose in front and 

 strongly and irregularly punctured behind. The canthus is not 

 v(>ry pi-ominent laterally and scarcely angular in front. The 

 pronotum is very minutely punctured in the middle, the punc- 

 tures becoming gradually more distinct laterall}^ and rugose at 

 the outer margins. The sides are gently rounded, with a 

 sharp but minute lateral angle far behuid the middle. The 

 elytra are finely and ratlier closely punctured dorsally, except 

 at the sutural margin, and the punctures become large and 

 dense at the sides. The lower surface is rather smooth, but the 

 mentum is rugose and the tip of the abdomen strongly punctured.
