Cleonus.~] RHTNCHOPHORA. 241 



Shirley, Leith Hill, Weybridge, Wimbledon, Chobbam, Sandbarst ; Norwich ; 

 Suffolk; Catubrklge; New Forest. 



C. g-laucus, F. (turbatus, Fahrs.). Very like the preceding, but 

 shorter, with the vertex not distinctly carinate, the posterior tibiae with 

 a longer spur, the prosternum without distinct tubercular prominences 

 before coxae, and the elytra shorter in proportion to the thorax, with the 

 alternate interstices less raised ; in size, general appearance, and mark- 

 ings, the species appears to closely resemble C. nebulosut. L. 12-13 

 inm. 



Heathy places ; at the roots of Ericaceae ; extremely rare and requires further con- 

 firmation as British ; Oekham and Kipley, Surrey (Steph. Man. 281); on a common 

 between Chobham and Ripley, seven specimens taken bj Mr. Xeale ill June, 1815 

 (Sccph. 111. iv. 155) ; Chobham, taken by Mr. Standish (8. Stevens). 



(C. uplitJialmif-us, Rossi (momus, Scop. ; quaflripunctatus, Schrank ; 

 distinctus, Steph. 111.). This species is now omitted from our lists ; it 

 is allied to C. albidus and C. sulcirostris in having the second joint of 

 the posterior tarsi short, and differs from the former in having the first 

 joint of the funiculus of the antenuse at least as long as the second ; 

 from the latter it may be known by having the mesosternal projection 

 broadly truncate between .the intermediate coxae, instead of being 

 terminated in a sharp or obtuse point (on this character Motschulsky has 

 placed it in a separate genus. Leucosomus) ; the colour is black, varied 

 with ashy pubescence ; the thorax is white at the sides and the elytra 

 are obscurely striated with several rows of elevated ashy hairs, and each 

 is furnished with two distinct white spots behind the middle, the 

 anterior of which is somewhat divided ; towards the base are some 

 rather lighter dashes ; on the breast are some fascicles of ashy down, 

 and the margins of the abdominal segments are pale ; legs black, 

 pubescent. L. 9-15 mm. 



Cooiube Wood and Epping Forest (Stephens) ; Stephens, however (III. iv. 153), says 

 he had only seen two specimens, one of which, from Coombe Wood, had been taken 

 about twenty years before. 



ZiZXUS, Fabricius. 



This is a very interesting genus which in some respects is closely 

 allied to Cleonus but differs in the fact that the scrobes cease at a 

 distance from the apex of rostrum, and also in the usually more elongate 

 form, the absence of the definite variegation of the elytra which is so 

 conspicuous in many species of Cleonus, and the fact that many of its 

 members have the power of secreting the dusty pollen-like matter 

 before referred to ; the sexual differences are unimportant ; the species 

 are very numerous, upwards of three hundred in number, and are very 

 widely distributed throughout the world from Siberia to the Cape of 

 Good Hope and Brazil ; in fact it appears to be one of the most uni- 

 versally distributed genera of the Rhynchophora ; as in the case of
