322 CLAVICORNIA. [Cnj ptophagus . 



C. cylindrua, Kies. (parallelus, Bris.). Allied to the preceding 

 species, but readily distinguished by its narrower and very cylindrical 

 form and longer elytra, which are much more closely and finely punc- 

 tured ; the lateral teeth of thorax, moreover, are situated a little 

 behind the middle of side instead of evidently before middle as 

 in C. dentatus ; it is one of the most distinct of our species. L. \\ 

 mm. 



Under bark of Scotch fir ; rare ; Scotland, Highlands, Tay and Dee districts, 

 Raunoch, Braemar, Aviemore, &c. 



C. distingruenduSf Sturm. A small and rather broad species, 

 somewhat variable in colour, being either rufous or occasionally brownish, 

 thickly clothed with fine pale pubescence ; antennae with the third joint 

 equal to the second ; thorax not very transverse with the anterior 

 angles not or scarcely visibly callosely reflexed, but projecting in the 

 form of a blunt tooth, lateral teeth situated a little behind middle of 

 sides, thickly and finely punctured ; elytra oval rather convex but 

 depressed on disc, very thickly and finely punctured, the punctuation 

 being occasionally slightly rugose in parts ; legs ferruginous, male with 

 the anterior tibiae and tarsi slightly dilated. L. 1-1 \ mm. 



In haystack and vegetable refuse, fungi, &c. ; not uncommon, but apparently 

 somewhat local ; Sheerness, Lee, Maidstone, Shirley near Croydon, Dulwich ; 

 Soham, Cambridgeshire ; Hastings ; Edgbaston, Sutton and Knowle, Birmingham 

 district ; Scarborough ; Northumberland district, scarce but rather widely dis- 

 tributed ; not recorded from Scotland or Ireland. 



The shape of the anterior angles of thorax, and the relative length 

 of the second and third joints of the antennae, as well as the very fine 

 punctuation, will serve to distinguish this species from most of the 

 others ; it is very closely allied to C. umbratus, and may very easily be 

 mistaken for that species ; the punctuation, however, is evidently finer, 

 and the base of the thorax is not furnished with a fold before scutellum, 

 which is very distinct in C. umbratus ; according to Thomson the 

 thorax is shorter than this latter species, but this hardly appears to be 

 correct. 



C. acutangrulus, Gyll. (Waterhousei, Rye). Elongate, rather 

 depressed, parallel-sided ; fusco-testaceous or rufous with the head and 

 thorax occasionally darker ; head and thorax very thickly punctured ; 

 thorax narrower than elytra, very transverse, with the anterior angles 

 strongly reflexed and produced in a large hook-shaped tooth, lateral 

 tooth situated in middle of sides which are narrowed towards base ; 

 elytra very long in proportion to thorax, thickly and finely punctured, 

 with a fine sutural stria behind, thickly covered with short and fine 

 pubescence ; legs ferruginous, anterior tarsi of male scarcely dilated. 

 L. 2-2f mm. 



In haystack and vegetable refuse, in fungi, &c. ; not uncommon, but apparently 

 somewhat local, and becoming rare towards the north ; London district, generally
