CRYPTOPHAGID.^. 129 



Anterior angles of thorax callose, but not strongly 

 cvip-shaped, bearing a sharp spine directed 

 backwards. Pubescence of elj'tra with longer 

 hairs outstanding fx^om the decumbent pubes- 

 cence. Anterior tibiae of the male triangularly 

 dilated from base to apex . . . ,0. pilosus, Gyll. 



Anterior angles of thorax strongly cup-shaped, not 

 bearing a spine. Pubescence of the elytra short, 

 even, without longer hairs. Anterior tibia^ almost 

 linear in the male, and more slender in both 

 sexes than in C. jnlosus C. badius, Sturm. 



C. bimaculatus, Panz. (Faun. Germ. 57, 7). A small species 

 which may be known from all others by the coloration and the struc- 

 ture of the thoi-ax, which is very transverse, about twice as broad as 

 long, with the sides scarcely rounded, and strongly and I'egularly 

 serrated, there being no trace of the stronger lateral tooth, which is 

 usually such a constant character in the genus. The general colour is 

 reddish-brown, variable in shade, rather shining, with a more or less 

 defined black band across the elytra ; this is divided often at the suture 

 and gives the insect a bimaculate appeai'ance ; the head is thickly and 

 rather deeply punctured^ and the antennae are rather short and slender ; 

 the thorax is somewhat convex, deeply and very thickly punctured, 

 and the elytra are longish oval, gently rounded at the sides, rather 

 strongly and not veiy closely punctured in front, more finely behind. 

 L. lf-2]- mm. 



Taken by Mr. Halbert and the late Mr. C. W. Buckle from June 

 to September 1902 by sweeping amongst large beds of rushes on the 

 shore of Lough Neagh, Ireland, bordering Shane's Castle demesne. 

 Introduced by Mr. Halbert as British (Irish Naturalist, xix. 2, p. 30, 

 February 1910). 



This insect is one of the most distinct of all the members of the 

 genus Cryptophagus. Ganglbauer (who places it first in his table and 

 first in his descriptions of the species) says that it is found rarely in 

 North and Central Europe and Siberia. 



C. loevendali, Ganglbauer = C. pubescens, var. loevendali, 

 Ganglbauer (Die Kiifer von Mitteleuropa, iii. G78 (1899)). This 

 specias very closely resembles C. j)uhe&cens, Sturm., but it has the club 

 of the antenna? three-jointed instead of apparently two-jointed as in 

 the last-named species, the ninth joint being only slightly less dilated 

 than the eleventh ; it may further be known from this species by its 

 darker colour and the rounded sides of the thorax ; it resembles in 

 colour the typical dark form of C. scanicus, from which it difiers in its 

 broader shape, coarser sculpture, and slightly less dilated ninth joint 

 of the antenna?. L. 2|-2i mm.
