366 RHYNCHOPHORA. [ Ceuthorrhynchidius. 
distinct lines of grey scales, elytra with blackish suture, and with rows of 
upright sete on the interstices ; head without white spot, rostrum long, 
ferruginous, antenne red ; thorax long, cluselyand rather deeply punetured, 
without lateral tubercles, not strongly constricted before apex, posterior 
margin slightly sinuate, nearly straight ; elytra subquadrate, narrowed 
behind, with rather strong punctured strize which are nearly as broad as 
the interstices, interstices slightly convex, apex with distinct tufts of 
yellowish-white bristles ; legs red, femora toothed. L. 2-25 mm. 
Male with the anterior tibize armed with a small tooth and the 
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. 
Cc. Chevrolati, Bris. (minimus, Walton’). 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 seales ; 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 
somewhat 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. 
On Achillea millefoliwum; very local; Lee, Weybridge, Cowley, Claygate, 
Boundstone, Brentford, Chatham, Birch Wood, Forest Hill; Dover; Hythe.

not strongly constricted in front, posterior margin almost straight, 
lateral tubercles small but distinet; elytra with rather strong punc- 
tured striz, interstices convex, with rows of recumbent hairs ; legs red.

On Artemisia maritima and Plantago lanceolata; also found at the roots of
