 (PI. VII. fig. 2.) 



C. niger ; elytris dorso fusco-castaneo, lateribus nigro-margi- 

 natis, vitta flava latiuscula notatis ; labro producto, trigono- 

 conico ; mandibulis porrectis, baud arcuatis, irregulariter 

 denticulatis, et intra basin versus fortiter emarginatis ; 

 tibiis anticis extus irregulariter denticulatis, quatuor pos- 

 ticis inermibus. 



Long, Corp. fere unc. 2 ; mandib. Hn. 8. 



Hab. Ins. Gilolo. Coll. Wallace. 



Mandibles nearly straight, slightly curved from the base to the 

 apex, which is bifurcate, the general surface flattened ; internally 

 at the base deeply emarginate, with one strong tooth just before 

 the middle, and two smaller ones behind and before it. 



Head with a large oblique flattened space on the crown, emar- 

 ginate in front, anterior angles obliquely truncate, sides slightly 

 swollen behind the eyes; labrum short, subtriangular, general 

 surface shining, but very delicately shagreened, covered beneath 

 with ferruginous hairs. Prothorax considerably wider than the 

 head, smooth, anterior angles somewhat produced, and truncate ; 

 anterior and posterior margins bisinuate, sides slightly waved, 

 posterior angles obliquely truncate. Elytra widest just below 

 the humeral angle, deep chestnut brown, narrowly margined with 

 black, with a widish yellow vitta extending from the shoulder 

 nearly to the apex, the vitta narrowest at the humeral angle. 

 Legs black, anterior tibiae armed externally with two teeth and 

 a few slight crenulations, intermediate and posterior tibiae unarmed ; 

 femora and trochanters of intermediate and hind legs furnished 

 behind with a narrow line of brownish hairs. 



This unique and fine species is named after A. R. Wallace, Esq., 

 to whose indefatigable exertions natural history in general is so 

 much indebted. Although somewhat approaching in general 

 appearance the gigantic species of the genus Odontolahis, it bears 

 nevertheless, I think, a nearer affinity to the species of that section 

 of the genus Cladognathus which Mr. Hope in his Catalogue 

 designated as Prosopoco'tlus, and of which Cladognathus Lafertei 

 may be considered the representative.
