and a neiv genus of Rliyncophorous Coleoptera. 17 



stouter than the 8th, so as to be intermediate in thickness 

 between it and the 10th. Thorax about as long as broad, 

 the front part constricted, the sides behind the constriction 

 curved and much narrowed towards the base ; the surface 

 is coarsely punctvired and sparingly clothed with yellow, 

 short setje ; it shows some depressions, which are, however, 

 rather ill-defined and variable, the most distinct and con- 

 stant being one near the front, in the middle. Elytra 

 rather short, reddish, with some irregular black marks, 

 the most distinct of which form a patchy band across the 

 middle ; they are clothed with patches of pale setiform 

 scales, and are rather coarsely but somewhat indistinctly 

 punctured, the punctures being scarcely placed in rows : 

 the base is emarginate, so that the shoulders are promi- 

 nent and acute, and quite disengaged from the base of the 

 thorax : the surface shows, besides the patches of scales, 

 scattered erect setffi. The legs are reddish, with the 

 thicker part of the femora nearly black. The under sur- 

 face is rough on the front parts ; the basal ventral seg- 

 ment is coarsely and distinctly punctured, the other four 

 segments are nearly impunctate. 



Found on a species of Hybiscus, and also on the candle- 

 nut tree. 



Proterhinus Blaclihurni, n. sp. Rufescens fere con- 

 color, setis elongatis, erectis conspicue vestitus, fortiter 

 rugoso-punotatus, opacus; elytrorum humeris promiuulis; 

 antennis articulo 2" quam tertio crassiore et paulo lon- 

 giore; femoribus minus clavatis. Long. If — 2| mm. 



First and second joints of antennae only moderately 

 stout ; 2nd, intermediate in thickness between the 1st and 

 3rd, and slightly longer than the latter. Thorax a good 

 deal narrower than the elytra, very coarsely punctured, 

 and bearing erect setas, which render its outline and sur- 

 face indistinct. Elytra rugose, with fine erect acute setae. 

 Legs of an uniform red colour. 



This species is readily distinguished fi'om P. vestitus 

 by the different basal joints of the antennae, as well as by 

 the slighter characters of colour, scidpture and clothing. 

 I have much pleasure in complimenting Mr. Blackburn, 

 by giving this species his name. 



Proterhinus simplex, n. sp. Minus robustus, rufescens, 

 antrorsum obscuriore, antennis nigris basi rufo; protho- 

 race lateribus curvatis, antrorsum hand vel vix constricto,
