marginated and nearly straight, front angles rectangular and sub- 

 acute, the posterior rectangular, base sinuate. AntenncB stout, 

 second joint as stout as but shorter than first, oviform, third almost 

 as long as fourth but much more slender. 



Its most natural position is near G. parviceps.

1730. C. aethiops, n.s. Convex, rather broad, unimpressed, 

 covered with fine, inconspicuous, cinereous hairs ; body shining, 

 wholly black, joints 2-6 of the antennee testaceous, the other joints, 

 palpi, tarsi, and knees brown. 



Head broad, no sub-ocular line, genal space sculptured, bearing 

 very minute distant granules. AntenncB stout, third articulation 

 nearly as long as but more slender than fourth. Thorax short, as 

 broad as elytra at base, margins fine, hind angles rectangular, 

 anterior obtuse, base sinuate, its sculpture like that of the head. 

 Elytra widest behind, moderately punctured. 



This species resembles G. rectangiUus, but in it the granules are 

 easily seen, whereas in this species the granules, when examined 

 under the miscroscope with a half-inch lens, appear like acute 

 prominences scarcely thicker than hairs. 



Length, i|- lines ; breadth, quite f. 



Mount Egmont, 3,200ft. Tolerably common. 



1 731- C trivialiSj n.s. Convex, neither broad nor narrow, 

 covered with fine, pale-yellow hairs, slightly shining, fuscous, the 

 sides of elytra generally more or less testaceous ; antennae, palpi, and 

 legs testaceous. 



Head broad, with very minute distant granules, genal space 

 sculptured, without any distinct carina. Antennce stout, third joint 

 nearly equalling the fourth in length but more slender. Thorax 

 short, nearly as broad as elytra at base, its angles rectangular, 

 sculptured like the head. Elytra widest behind, indistinctly im- 

 pressed near the base, moderately punctured. Underside fuscous, 

 with fine, pale-yellow hairs. 



The proper place for this little species is, I think, near C, 

 oscillans.

1732. C. coloratum, i^-s. Lanceolate, finely and densely 

 reticulated, shining ; thorax and elytra fusco-niger, head and legs 

 obscure-red, underside piceous ; the palpi, a sub-apical fascia, and an 

 elongate vitta on each elytron yellow ; the posterior edge of the 

 vitta, and most part of the elytral margins, rufous. 



Head rather small, bearing some fine punctures and minute 

 greyish hairs. Antennce long, blackish. Thorax considerably con-
