admitted that the first of tliese characters is not easy to distinguish ; in 

 colour it is more or less fuscous with the elytra and sides of thorax 

 sometimes lighter; it may also, as a rule, be separated from C. cideloides 

 by the shape of the thorax, and from lioth that species and C. aiujudata 

 it may be known by the shape of tlie elytra^ which have the sides dis- 

 tinctly less parallel and more dilated. L. 5 mm.

C. spadicea, Sturm. A rather broad and robust species ; head, 

 thorax, and under surface pitchy black, elytra chestnut brown ; in some 

 specimens the thorax also is more or less brown ; head rather long, with 

 prominent eyes, antenucB long and slender, reddish-testaceous, darker 

 towards apex ; thorax plainly narrower than elytra, broader than long, 

 with the sides rather strongly rounded, upper surface strongly punctured, 

 margms broad and explanate, posterior angles obtuse and rounded ; elytra 

 rounded and dilated at sides, broadest, as a rule, a little behind middle, 

 with rather distinct strite, and the interstices plainly and rugosely punc- 

 tured ; legs ferruginous, posterior trochanters gouge-shaped. L. 5 mm. 



In de;id leaves, fungi, &c. ; rare; Highgate (Waterhouse and Power); Bexley,

 in Lungworth Wood by myseU') ; Scotland, rare, Tay district (llaunoch (Sharp)). 



C. ag'ilis, 111. Shorter, broader, and more coiivex than G. cmr/ustafa 

 and its allied species, and easily distinguished by its short thorax, Avhich 

 is broadest at or just before base; colour variable, lighter or darker 

 ferruginous brown ; antenmie reddish, usually darker towards apex ; 

 thorax finely punctured, with the lateral margins not raised, about as 

 broad at base as elytra, with posterior angles obtusely rounded ; elytra 

 convex, very feebly striate', closely but rather distinctly punctured; 

 legs ferruginous, male with the posterior trochanters armed on the inner 

 side with a short curved strong pointed tooth, and the middle tibiie 

 bent strongly inwards. L. 4|-8 mm.

 tributed throughout the southern and midland districts ; less common further north ; 

 Scotland, rare, Clyde district and Isle of Arrau ; Ireland, near Belfast. 



(Sub.-Gen. Kargrus, Thomson.) 



This sub-genus contains sixteen European species, of which three are 

 British ; they are much smaller and more ovate than the members of the 

 preceding sub-genus, but by their slender antennae and in other points they 

 much resemble them ; they are easily distinguished from the species 

 belonging to the other sub-genera. 



I. Posterior angles right angles ; upper surface dull ; 



size larger C. Velox, Spence.
