Coleoptera from the Hmcctiian Islands. 95 



and not easily seen, are not rounded, but somewhat 

 obtusely rectangular: the blackish elytra form a striking 

 contrast in colour to the head and thorax. The whole 

 surface is smooth and shining and nearly free from punc- 

 tuation. 



Found near Honolulu; sent as No. 43. 



Cls evnnescens, n. sp. Suboblongus, parum convexus, 

 nitidus, subla^vigatus, nigricans, pedibus fusco-testaceis, 

 antennis basi testaceo, apice fusco. Long. 1| mm. 



The antennae are stout, with rather thick short club. 

 The minute head is without raised margin, but has a 

 very distinct transverse impression in front. Although 

 the thorax is but little produced over the head, it is a 

 gofjd deal longer in the middle than at the sides, and the 

 front angles are extremely rounded and indistinct ; it is 

 distinctly narrowed behind, and the hind angles, though 

 very obtuse, are not rounded. The surface is almost free 

 from ])unctuation. 



This species seems closely allied to C. Iceficniiis, but in 

 addition to its black head and thorax, the more obtuse 

 hinder angles of its thorax characterize it as a distinct 

 species. 



Found on the mountains of Oahu and Kauai; sent as 

 Nos. 32 and 213.

Proterhinus( Sharp, Trans. Ent. Soc. Lond. 1878, p. 20). 



Proterhiuus nujricnns, n. sp. Latiusculus, nigricans, 

 setis depressis, submaculatim vestitus, setis erectis pamun 

 conspicuis; antennarum articulo basali magno; prothorace 

 latiusculo, anterius })arum distincte constricto, lateribus 

 valde rotundatis, dense profundeque punctato, anterius 

 impresso; elytris brevibus, basi subplanato, versus hiimeros 

 leviter angustatis (his sat acutis), crebre profundeque punc- 

 tatis. Long. 2\ — 3 mm. 



This species differs fi-om P. vestitus in the following 

 points : it is darker in colour, even the legs and antennas 

 being blackish ; it has the eyes larger, the antennae rather 

 longer and thicker, with larger basal joint, and the punc- 

 tuation of the surface has a more distinct and definite 

 appearance, owing, perhaps, to the seta; being lesa deve-
