196 SERRICORNIA. { Lasioderma. 
gradually narrowed in front, very finely punctured, posterior angles 
rounded; scutellum small; elytra very finely punctured; legs clear 
reddish-yellow, moderately long, with the tarsi short, the first joint 
being twice as long as the second. L. 2 mm. 
A cosmopolitan species, occurring in ginger, liquorice, &e. ; London, and probably 
other large towns into which it has been imported. Mr. Champion says that it is 
not uncommon, but it is very rare in our collections, 
DORCATOMINA. 
The species belonging to this tribe differ entirely in shape and general 
appearance from the rest of the Anobiida, being of a short round oval 
or almost hemispherical form, and very convex; the head when de- 
flexed is received into a hollow in the prosternum, and the mandibles 
are applied to the mesosternum or the prolongation of the metasternum be- 
tween the intermediate coxe ; the antenne are received into a deep cavity 
between the anterior cox; they are short, with the three last joints 
serrate, and, as a rule, much dilated ; the first joint is also enlarged ; the 
first ventral segment is deeply excavated on each side for the reception 
of the hind legs. 
Seven genera and twenty-three species are included in the European 
catalogue as belonging to the tribe; of these, three genera, represented 
by four species, are found in Britain. 
I. Eyes divided beyond middle; antennz 9-jointed . . . Ca@nocara, Thoms. 
II. Eyes entire. 
ji. Antennas 10-jointed, rarely 9-jointed; form oval . Dorcatoma, Herbst. 
ii, Antenne 8-jointed; form nearly hemispherical . . . Awnrrys, Thoms, 
CENOCARA, Thomson. 
This genus contains half-a-dozen species from Europe and North 
America; they may be known from our other members belonging to the 
tribe by having the eyes divided beyond the middle ; the prosternum is 
furnished behind with a very short process, which is broadly emarginate 
at apex. 
C. bovista, Hoff. (subalpina, Bon.; Enneatoma subalpina, Muls.). 
Subglobose, almost hemispherical, convex, but slightly depressed on disc, 
about as long as broad, shining black, with the apex and margins of the 
elytra sometimes reddish, sparingly clothed with rather short greyish 
pubescence, finely but not very closely punctured, the punctuation of 
the elytra being less close than that of the thorax ; head moderately 
large with eyes somewhat prominent, antenne pitchy, 9-jointed, with 
the first joint long and enlarged, the second very much smaller, 
the four following very small, and the last three much enlarged ; 
thorax much broader than long at base, gradually and strongly narrowed 
in front, with base bisinuate, posterior angles blunt; elytra with well-
