when alarmed, of causing tlieir femora to droop, as it were, and 

 project at a right angle from the body— by the pectoral groove be- 

 neath the thorax being abbreviated, the femora canaliculated, &c.

Cu. cyaneus, LinnL— Or. cyaneus. Steph. Catal. 152. No. 1526. 



Black, glabrous, very shining, beneath with white scales: rostrum punctate, 

 substriate: head punctured: thorax sometimes tinged with bluish, or violaceous^ 

 very obsoletely punctulated : scutellum with white scales : elytra very convex, 

 deep black-blue or violaceous, very faintly striated, the striae and interstices 

 impunctate, the latter flat ; legs pitchy-black, with cinereous scales; tibiae and 

 tarsi pale rusty-brown : antennae the same. 



The sandy lane leading into Darenth-wood is the only locality I 

 have ever found this insect in ; I have there taken several examples 

 at different periods during the month of June : the insect occurs, but 

 sparingly, near Bristol. " On Salix argentea, and among herbage 

 on Crwmlyn Burrows, not very uncommon." — L. W. Dillwyn, Esq. 



Genus CCLXXXIII. — Ceutorhynchus, Schuppel. 



Antennce geniculated, 12-jointed, rather slender, inserted towards the apex or the 

 middle of the rostrum; the funiculus seven-jointed, its basal joint longer than 

 the rest and somewhat obconic ; the remainder short, lenticular : club ovate, 

 acuminated, four-jointed. Rostrum inflexed, elongate, curved, inserted during 

 repose in a pectoral groove, which is continued to the base of the intermediate 

 legs, and is strongly margined; thorax considerably attenuated anteriorly, 

 bisinuated posteriorly : scutellum minute : bodi/ somewhat rhomboid, scabrous : 

 elytra subtriangular, shorter than the abdomen : legs moderate, stout ; femora 

 clavate, sometimes dentate ; tibia; truncate at the apex, unarmed ; tarsi with 

 two claws. 



This obscure genus differs from Orobitis in having the body more 

 or less rhomboid in shape, and rugose or scaly : the rostrum is of 

 dissimilar form, more lengthened, and is inserted during repose in a 

 pectoral groove, which reaches to the base of the intermediate legs, 

 by which it differs from Nedyus : the thorax is very much con- 

 stricted in front, and is sometimes tuberculated : there is consider- 

 able diversity of appearance amongst the species, which frequent 

 trees and herbs. 



A. With the thorax not tuberculated, nor reflexed in front.
