Cholera.'} CLAVICORNIA. 57 



admitted that the first of these 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. cisteloides 

 by the shape of the thorax, and from both that species and C. angustata 

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

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



In moss, dead leaves, &c. ; rare ; Birch Wood, Claygate, Lee, Shirley, Cowley, 

 Highgate ; Dover; Hastings; Wicken Fen; Knowle, near Birmingham; Lan- 

 caster. 



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, antennae 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, 

 margins 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 stria?, and the interstices plainly and rugosely punc- 

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



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

 Surrey (Champion), Cootube Wood (Rye), Shirley, near Croydon, and St. Mary Cray 

 (Sharp); Bishop's Wood, Dulwich ; Holm Bush, near Brighton (Power); Repton 

 (W. (jarneys) ; Driukwater Park, Manchester (Reston) ; Lincoln (one specimen taken 

 in Langworth Wood by myself) ; Scotland, rare, Tay district (Raunoch (Sharp)). 



C. ag'ilis, 111. Shorter, broader, and more convex than C. angustata 

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

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

 ferruginous brown ; antenna? 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 1, 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 tibia? 

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



In dead leaves, moss, haystack refuse, &c. ; not uncommon, and rather widely dis- 

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

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



(Sub.-Gen. Narg-us, Thomson.) 



TFiis 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. VEIOX, Spence.
