 upright setae on the interstices ; head without white spot, rostrum long, 

 ferruginous, antennae red ; thorax long, closelyand rather deeply punctured, 

 without lateral tubercles, not strongly constricted before apex, posterior 

 margin slightly sinuate, nearly straight ; elytra subquadrate, narrowed

 posterior with a larger one ; last ventral segment slightly depressed. 



On Plantago lanceolata, and other species of Plantain ; common and generally 

 distributed throughout the kingdom. 



C. Chevrolati, Bris. (minimus, Walton 1). This species has been 

 by many authors considered a variety of the preceding ; it may be at 

 once known by the variegated colouring of the upper side, which is 

 covered with a thickly set pattern of white scales, the central and side 

 lines of thorax, a patch on each side of the scutellum and certain 

 markings behind the middle of the elytra being most conspicuous ; the 

 head between eyes is thickly covered with scales ; the thorax is furnished 

 with obsolete, but visible, lateral tubercles and the elytra are rather 

 broader in proportion to the thorax ; these characters, however, are 

 eomewhat variable, and it must be confessed, that, apart from the 

 clothing of scales, the species is extremely closely allied to C. troglodytes. 

 L. 2 mm.
