Hah. Solomon Islands, Alu (C. 71/. Woodford, Esq.). 



This species is quite unlike any with which I am acquain- 

 ted. The comparatively straight acuminate mandibles have 

 a double short tooth at the base, with a trace of another at 

 the middle. The elytra are striated, with the third and fifth 

 interstices very narrow, distinctly and moderately closely 

 punctured, more strongly punctured beyond the seventh 

 stria, the base and the margins rugose. The margins are 

 beset with very short hairs, which are slightly separated from 

 each other. 



Fiqvlinm. 



Nigidius divergens. 



Niger, nitidus. Capite antice leviter concavo, confertim punetato, 

 oculorum canthis retrorsum directis, divergentibus, acutis. Tho- 

 race bene convexo, supra parce subtiliter punetato, ad latera sat 

 fortiter punetato ; margine antico fortiter impresso, creberrime 

 rugoso punetato, linea brevi mediana elevata instructo ; disco 

 medio linea fortiter punctata impresso, ante medium utrinque 

 fovea impresso ; lateribus subparallelis, pone angulos anticos 

 incisura parva, Elytris sulcatis, sulcis fortiter punctatis, inter- 

 stitiis costiformibus Iambus. 



Long. (mand. excl.) 10| lin. 



Hab. Lake Nyassa (Thelwall). 



Very near N. bubalus. The mandibles as in that species ; 

 very closely and coarsely punctured on the inner side of the 

 erect horn, which has the tip turned in nearly at right angles
