Genus CCLIV. — Gibbium, Kugellan. 



Antennae approximating, subsetaceous, the articulations cylindric ; the second, 

 third, and fourth rather thickened ; the terminal joint slightly elongate and 

 obtusely acuminated at the apex : head deeply inserted in the thorax, which 

 is short, transverse, smooth, produced in the middle behind, in place of the 

 scutellum, which is wanting : eyes minute : body ovate, gibbous, compressed 

 laterally: elytra connate, glossy, smooth: legs elongate : femora suddenly 

 clavate at the apex. 



Gibbium may be readily known from Mezium, which it re- 

 sembles in having the elytra connate, glabrous, and shining, by the 

 short, smooth thorax, the incrassation of the second, third, and 

 fourth joints of the antennas, the obtusely acuminated terminal joint, 

 and the compressed form of body.

Shining castaneous, impunctate : with the antennae and legs pubescent. 



Rare in the south, but apparently not very uncommon in the 

 north of England. " Bristol." — Mr. Millard. " Newcastle-on-

Genus CCLV. — Dorcatoma, Herbst. 



Antenna? with the basal joint robust, somewhat elongated and bent; the second 

 small, nodose, or slightly produced within : the six following extremely mi- 

 nute and slender ; the remainder very large, compressed, triangular, the two 

 basal ones more or less produced within. Palpi four, unequal, securiform ; 

 head short, transverse: thorax transverse, sinuated or rounded behind; elytra 

 striated laterally, punctate on the back : legs short, simple ; tarsi very short. 



The singularly constructed antennae of Dorcatoma sufficiently 

 distinguish this genus from the rest of the family, the first joint 

 thereof being incrassated, the second small, but still comparatively
