tuied, interstices vatlier narrow. ScuteUum curvilinearly 

 triangular, punctate. Elytra rather wider than tlie thorax at 

 the base and becoming gradually wider towards the hind 

 tliighs, from thence much narrowed apicallj ; the sides, as 

 far as these thighs, are evidently concave, but beliind that 

 point they are quite flat or depressed, with transverse foveas 

 and ])unctures ; the suture is plane, but on each elytron there 

 are tiuee more or less dis-tinct discoidal costje, the two outer 

 become convergent behind, there are also indications of other 

 longitudinal interrupted lines between the costai ; the surface 

 is irregularly and coarsely punctured, with narrow and 

 apparently raised intervals as far as the second costs, but 

 outside that area the sculpture is intermingled with numerous 

 small granular elevations, some of which almost form regular 

 series towards the hind slope, so that the general sculpture in 

 certain lights seems somewhat linear; the lateral margins are 

 reflexed and minutely sculptured. 



Legs and tarsi normal, closely and rugosely punctured, 

 with fine flavescent pubescence. Antennce punctate, second 

 joint rather longer than broad, third not twice the length of 

 the following one ; joints 4 to 8 longer than broad, 9 to 11 

 more rufescent and /nore liiiely pubescent, 11 oval. 



Underside a little nitid, distinctly punctate, with a very 

 minute seta in each puncture ; prosternum more coarsely and 

 rugosely punctured. 



The stature is that of C. opacula, but the sculpture bears 

 more resemblance to that of the smaller C. granulosa and 

 C. ritgosa, tlius rendering this species unusually distinct.

Group Rhyparosomidae. 



Htcanus, gen. nov. 



Bostrum rather shorter than thorax, stout, broadest and 

 pterygiate at the point of antennal insertion, so that it af)pear3 

 contracted behind ; its ajjical portion smooth and shining, the 

 remainder rugose-punctate. Scrobes quite open above in 

 front, directed towards but not quite reaching the eyes. 

 Mandibles prominent, laminate. £t/es almost rotundate, 

 flat, distinctly facetted, just free from thorax and widely 

 distant from each other. Antennm imj)lanted before the 

 middle. Scope stout, clavate, attaining the back part of the 

 eye. Funiculus obviously longer than scape, basal joint only
