196 SERRICORNIA. [Latiuderma. 



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, &c. ; London, -and probably 

 other large towns into which it has been imported. Mr. Clmmpiou 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 Anobiidra, 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 coxae ; the antennae are received into a deep cavity 

 between the anterior coxae ; 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 ; antennae 9-jointed . . . CCBNOCARA, Thorn*. 

 II. Eyes entire. 



i. Antenna 10-jointed, rarely 9-jointed ; form oval . . . DOBCATOMA, fferbst. 



ii. Antennae 8-jointed j form nearly hemispherical . . . ANITYS, Thorns. 



C02NOCARA, 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. bovlstee, Hoff. (subalpina, Bon.; Enneatoma subalfrina, 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, antennae 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-
