318 CLAVICORNIA. [Cryptophagus. 



appears to be the C. grandis of Kraatz, which has been before now in- 

 troduced into our lists as a distinct species. 



SECTION III. 



The four species contained in this section are distinguished by having 

 a longitudinal fold at base of thorax before scutellum, the transverse 

 impression being deep ; the elytra are not setose, and the pubescence 

 and punctuation are fine, both being more marked in G. badius than in 

 the other three species. 



I. Anterior angles of thorax scarcely reflexed, forming no 

 distinct tooth behind ; upper surface very convex j form 



almost ovate ; punctuation of elytra very fine .... C. SAGINATUS, Sturm. 



II. Anterior angles of thorax scarcely reflexed, forming a 



blunt tooth behind ; punctuation of elytra less fine. 



i. Thorax subquadrate with sides almost parallel, usually 



darker than elytra C. UMBRATUS, Er, 



ii. Thorax rather strongly transverse, distinctly widened 

 iu middle, and thence contracted to base, usually 

 lighter than elytra C. SCANICUS, L. 



III. Anterior angles of thorax broadly reflexed and produced 

 behind into a more or less distinct sharp tooth ; punc- 

 tuation of elytra moderately strong ... . . . . C. BADIUS, Sturm. 



C. sag-inatus, Sturm. Subovate, convex, entirely ferruginous or 

 reddish-testaceous, rather thickly clothed with short depressed pubes- 

 cence ; head and thorax thickly and rather deeply punctured ; antennae 

 with a moderate club ; thorax transverse, with the anterior angles cal- 

 lose but scarcely reflexed, and with a distinct tooth at sides before 

 middle, from which the sides are gently contracted to base; elytra 

 finely punctured ; legs ferruginous or reddish-testaceous. L. 2-2^ mm. 



Male with the anterior tibiae scarcely dilated, and the anterior tarsi 

 slightly widened. 



In haystack and vegetable refuse, fungi, &c. ; occasionally found in birds' nests J 

 it often occurs in warehouses ; not uncommon and generally distributed throughout 

 England ; Scotland, rare, Forth and Tay districts ; it is probably general in Ireland. 



This species rather closely resembles light specimens of C. scanicus, 

 but may be distinguished by its more ovate and convex form, the less 

 distinctly callose and reflexed anterior angles of thorax, and the fact that 

 the lateral tooth is situated before the middle ; in some respects it is 

 related to C. pilosus; its differences from that species have been above 

 referred to. 



C. umbratus, Er. Oblong, slightly convex, shining, with short 

 fine pubescence, nigro-fuscous at least on the under-side ; the colour of 

 the upper-side is somewhat variable, but the thorax is usually distinctly 

 darker than the elytra ; thorax not very transverse, subquadrate, with 

 the anterior angles scarcely reflexed and produced in a blunt angle
