Hypophleus. HETEROMERA. 23 
closely and unevenly punctured in front with traces of fine strie, the 
punctuation becoming obsolete behind; antenne and legs red or 
ferruginous red. L. 3-31 mm. 
Under bark of elms; very local; London district, rather common, Camberwell, 
Kennington, Forest Hill, Lee, Chatham, Sydenham, Charlton, Wimbledon, Horsell, 
Epping Forest, Brockley, &c.; Norfolk; near Manchester, Dukinfield, under pine 
bark (Chappell). 
LATHETICUS, Waterhouse. 
This genus, which has comparatively recently been described by Mr. 
Waterhouse, 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 antenne, which are partially concealed hy 
the clypeus which is almost as long as the rest of the head; the eyes 
are only slightly emarginate ; the thorax is subquadrate, 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. 
L. oryze, 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, antenne 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 antenne gradually thickened 
towards apex ; the epipleurz of the elytra are narrow or moderate ; the 
anterior coxe are rounded, the middle coxz are furnished with a distinct 
trochantin, and the posterior cox are not widely separated ; the tibial 
spurs are short or very short, and the tarsi are pubescent beneath, the
