CRYPTOPHAGID^. 131 



settled a difficulty which has puzzled several coleopterists who have 

 included this insect doubtfull}^ under C. scanicus ; it is considerably 

 duller than that species and diflerently shaped and punctured ; it is 

 rn.ther closely related to G. suhjumatus, Kx\, but is smaller. The 

 anterior angles of the thorax are more strongly callose and more 

 strongly toothed behind, and the elytra are broader, duller, and 

 more strongly punctured than the thorax; from C. hirtulus, Kr., 

 it may be known by the much wider margin of the thorax. In 

 the strong punctuation of the apex of the elytra C. fowleri comes 

 near C. validus, Kr., and C. suhdepressus, Gyll., but is much smaller than 

 the former, and has a quite differently shaped thorax as compared Avith 

 the last-named species {v. Ent. Mo. Mag. xlvi. (2 Ser. xxi.) 1910, 205). 

 C. hirtulus, Kraatz (B. 185S, lo8). Closely allied to C. scanicus, L., 

 and intermediate, as a rule, in colour between the type form of that insect 

 and the var. 2Xifruelis, Sturm. It may be known from C. scanicus and 

 also from the Central and South European species, C. thomsoni, Reitt., 

 by the longer, coarser and thicker pubescence, and by the structure of 

 the thorax, the anterior angles of which are more prominent, and 

 terminate behind in a sharp tooth ; the middle tooth is larger and the 

 sides are strongly angled and more contracted behind. It may further 

 be distinguished from C. scanicus by the much more finely margined 

 sides of the thorax, a character in which it agrees with C. cylindrus, 

 Kies., from which it maybe separated by its much broader form. The 

 head and thorax are usually ferruginous, sometimes brownish, and the 

 elytra brownish-yellow, but the whole body is often ferruginous or 

 brownish-yellow ; the punctuation of the upper surface is strong 

 throughout, and the elytra are somewhat more strongly punctured 

 than in C. scanicus. L. 2-2^ mm. 



Tresco, Scilly Isles, and Reading (Joy) ; Merton, Surrey (Newbery); 

 Woking (Champion). The species was introduced by Dr. Joy as 

 British (Ent. Mo. Mag. xliv. (2 Ser. xix.) 1908, 178). 



C. pallidus, Sturm. (Deutsch. Ins. xvi. 69, t. cccxiii. f. c). Very 

 closely allied to 0. dentatus, and perhaps scarcely distinct from that 

 insect, but it is generally rather smaller, with the thorax narrower in 

 proportion to the elytra, and the elytra shorter and less parallel. The 

 callosities also of the thorax are distinctly less developed ; the differ- 

 ences appear to be constant. The manner of life, too, is diffex'ent, 

 C. dentatus occurring in houses and cellars and under fallen leaves and 

 bark, whereas C. pallidus is found on flowering shrubs, especially a 

 species of Prunus, and in haystack refuse. L. 1 '>-2i mm. 



Lowther Castle, Westmorland, and Great Salkeld, Cumberland^ in 

 some numbers (Britten). It is probably to be found in many of our 

 collections, mixed with G. dentatus {v. Ent. Mo. Mag. xliii. (2 Ser. xviii.)

 field (Joy) ; Bedingfield and Bungay, and other Norfolk and Suffolk 

 localities (Garneys) ; Crystal Palace windows (Garneys) ; Repton, 

 Derbyshire (Garneys) ; Ditchling (Dollman).
