HypophlceuiJ] HETEROMERA. 23 



closely and unevenly punctured in front with traces of fine striae, the 

 punctuation becoming obsolete behind ; antennae and legs red or 

 ferruginous red. L. 3-3^ mm. 



Under bark of elms ; very local ; London district, rather common, Carnberwell, 

 Kennington, Forest Hill, Lee, Chatham, Sydenham, Charlton, Wimbledon, Horsell, 

 Epping Forest, Brockley, &c. ; Norfolk ; near Manchester, Dukinfield, under pine 

 bark (Chappell). 



XiATHETICUS, "VYaterhou.se. 



This genus, which has comparatively recently been described by Mr. 

 Watcrhouse, appears to be an evident importation, and ought not perhaps 

 to be considered indigenous ; for the same reason, however, several of 

 the other genera, whose members live on meal and flour, might with 

 reason be excluded ; the single species known may at once be dis- 

 tinguished by its very short antennae, which are partially concealed by 

 the clypeus which is almost as long as the rest of the head ; the eyes 

 are only slightly emarginate ; the thorax is suhquadrate, and the elytra 

 are parallel-sided and depressed, and completely cover the abdomen ; the 

 first joint of the posterior tarsi, if viewed sideways, is evidently longer 

 than the second, but if viewed from above appears almost equal to it. 



Zi. oryzae, "Wat. A small testaceous or rufo-testaceous species, 

 elongate-oblong, very linear and parallel, slightly shining ; head large, 

 finely punctured, together with eyes as broad as thorax, antennas stout 

 and extremely short, not or scarcely as long as head ; thorax subquadrate, 

 closely and finely punctured ; elytra with fine rows of punctures, 

 interstices minutely sculptured, very finely rugose, at least in parts; legs 

 slender, clear reddish-testaceous. L. 2| mm. 



A cosmopolitan species ; occurring in rice, flour, &c. ; it has occurred in the neigh- 

 bourhood of London ; one example has been taken by Mr. Marsh at Lee, Kent, by 

 sweeping; it ought perhaps to be excluded from the British list, but a considerable 

 number of others might be excluded on the same grounds. 



HELOPINA. 



This tribe is represented by a large number of tropical genera ; 

 eighteen are assigned to it in the European catalogue of Heyden, Reitter, 

 and Weise, but several of these are considered by most authors as 

 merely divisions of the large genus Helops ; the members of the tribe 

 may be distinguished superficially by having the front separated from 

 the clypeus by a distinct coriaceous band ; they are large or moderate- 

 sized oval or oblong-oval insects, with the eyes transverse, the front 

 more or less dilated before eyes, and the antennae gradually thickened 

 towards apex; the epipleurse of the elytra are narrow or moderate ; the 

 anterior coxae are rounded, the middle coxae are furnished with a distinct 

 trochantin, and the posterior coxae are not widely separated ; the tibial 

 spurs are short or very short, and the tarsi are pubescent beneath, the
