damelli, Macl., though both Gestro and de Cliaudoir have agreed 

 in regarding it as so. The present species has the fascies of a 

 Ifurus, but can readily be distinguished by the want of a basal 

 border to the elytra, and absence of squaraulse on the lower surface 

 of any of the joints of the anterior tarsi in the ^. 



NuRiDius, n.gen. 



Head large, with strong frontal impressions, the sides not pro- 

 tuberant behind the eyes ; two supra-orbital punctures on each- 

 side ; eyes convex. 



Lahrum sexsetose, broad, rounded in front. 



Palpi as in Homalosoma ; penultimate joint of labial palpi with 

 5 long setse in front, and two short setse (one at each side) near 

 the apex. 



Mentum, clyj)eus, mandibles, and antennae not differing from 

 Homalosoma. 



Protliorax subquadrate, transverse, a little narrowed behind ; 

 a flattened space along the base between the lateral basal impres- 

 sions ; basal angles rounded ; posterior marginal puncture placed 

 within the lateral margin. 



Elytra subcostate, convex, broad, not narrowed behind ; apex 

 broadly rounded, not sinuate ; base without a border ; shoulders 

 subdentiform. 



Body apterous, subpedunculate. 



Prosternum and mesosternum setigero-punctate. 



Metasternal episterna broader than long. 



Legs : anterior femora with a row of setigerous punctures in 

 front, extending to near apex ; anterior tarsi in ^ hardly 

 dilatate and without squamuliB below, basal joint as long as two 

 succeeding joints taken together ; posterior trochanters short, 

 obtusely rounded at apex. 



NuRiDius FORTis, n.sp. 



Black, shining, the elytra a little opaque ; elytra without a 

 basal border ; body subpedunculate.
