12 MANDIBULATA. — COLEOPTERA. 



tioribus, antennis palpis pedibusque rufo-brunneis, articulo ultimo antennarum 

 conico. (Long. corp. l| lin.) 



Ca. Spencii. Steph. Catal. 73. No. 792. 



Rather less than the last; obovate, black-brown, with the elytra paler, clothed 

 with a pale hoary fulvescent down ; palpi rufo-brunneous ; antennae rather 

 slender, longer than the thorax, with the club not much thickened, the 

 eighth joint very short and narrow, the terminal conic-acute, elytra dilated 

 a little way from the base, and then somewhat suddenly acuminated to the 

 apex, which is a little rounded, and distinctly striated ; legs rufo-brunneous. 



Shorter and comparatively broader than the preceding, which it most resembles, 

 the thorax more narrowed behind, and the base of the elytra also very narrow 

 the middle dilated, and the apex acuminated; antennas more slender. 



A single specimen taken by myself near London, some years 

 since. 



Sp. 11. caliginosus. Oblongo-bvalis, atro-niger, antennarum basi apiceque, fe- 



moribus anticis, tibiis tarsisque rufo-testaceis. (Long. corp. 2 lin.) 

 Ca. caliginosus. Steph. Catal. 73. No. 793. 



Oblong-ovate, deep black, clothed with fusco-grisescent down ; labrum, palpi, 

 base of the antennas, and the terminal joint of the latter, with the anterior 

 femora, tibiae, and tarsi rufo-testaceous ; elytra obsoletely striated, the apex 

 rounded ; antennae rather slender, longer than the thorax, the eighth joint 

 not very much slighter, but shorter, than the adjoining. 



In form somewhat resembling Ca. chrysomeloides, but more elongate, of a 

 deeper black, smaller, the antennae more attenuated in proportion, and with 

 the eighth joint larger. 



Two specimens found near London. 



b. With the sides of the thorax rounded from the base to the apex : the hinder 

 margin without excision. 



Sp. 12. Marshami. Oblongo-ovalis fuscus, antennis, thoracis longitudine, pedi- 

 busque flavo-f errugineis ; elytris apice obtusiusculis. (Long. corp. 2^ lin.) 



Ch. Marshami. Spence.—Ca. Marshami. Steph. Catal. 73. No. 794. 



Oblong-oval, fuscous, clothed with a griseous-yellowish pubescence, labrum 

 and palpi yellow-ferruginous, antennae the same, darker in the middle, sub- 

 clavate, as long as or rather longer than the thorax, the eighth joint con- 

 siderably less than the adjoining, the terminal ovate; thorax transversely- 

 subquadrate; elytra very obsoletely striated towards the apex, the latter 

 somewhat obtuse ; legs yellow-ferruginous. 



Var. j3. Pitchy-black, with the antennae and legs ferruginous. 



Longer, with the thorax less transverse, than the following species, which is 

 the only one of the genus with which it can be confounded, if due attention 

 be paid to the form of the thorax, which in this genus is essential. 



I possess a pair of this insect : one from the Marshamian cabinet
