a median sulcus, and an impression on each side ; metazona 

 depressed. Sternal plates brown. Pronotum long, constricted 

 posteriorly ; mesosternum transverse, truncate posteriorly ; meta- 

 sternum with lobe short, broad and truncate. Elytra black 

 with a shining purple sheen ; ample, long, very broad, well 

 rounded at the shoulders, the costa rounded, the apex truncate ; 

 a distinct keel runs the whole length of the costal told from the 

 shoulder to the apex. Wings prominent, shining purple-black, 

 with an orange spot at the apex. Legs long, rather compressed, 

 black ; tibiie smooth above, depressed only at the extreme apex 

 «n the upper margin. Abdomen broad, rather depressed, reddish 

 black. Last dorsal segment of c? ample, transverse ; posterior 

 margin depressed in the middle, with a crenulated, transverse, 

 crested tubercle on each side over the roots of the forceps, and 

 the exterior angles produced to a point ; in the $ as in the 6 , 

 but the tubercles more tumid, less crenulate. Penultimate 

 ventral segment of cf and $ ample, broad and rounded. Pygidium 

 of c? very short, almost hidden; of $ short and broad, with a 

 short quadrangular lobe on the posterior margin. Porceps with 

 the branches reddish black, remote at the base, depressed, trigonal, 

 elongated and robust; in the J bent somewhat downwards and 

 gently arcuate, enclosing an elongate oval area, with a pair of 

 strong conical teeth near the base on the inner margin and a 

 blunt crested tooth just beyond, then crenulate as far as a strong 

 sharp tooth just before the apex ; in the $ the branches are 

 even more elongate, scarcely arcuate, gently converging, with a 

 strong conical tooth near the base, another conical tooth at a 

 quarter the length and another about half-way down the forceps ; 

 beyond this crenulate to the apex, which is hooked ; the forceps 

 -are even more strongly depi*essed in the apical than in the basal

SiKKiM (coll. Burr). 



Also from Johore, Mentawei Island, Sumatra, and Borneo. 



The original specimens are quoted as being in Dohrn's col- 

 lection, Westermann's, and in the Berlin Museum. It is un- 

 certain which is the true type. 



This very fine species is easy to recognize from its great size, 

 «,part from the form of the forceps and the generic characters. 



In 1900, de Bormans separated Ch. dorice, but this is nothing 

 more or less than the male of C7i. superha, Dohru.
