RHYXCHOPHORA. Ill 



of the antennae is twice as long as the third, whereas in B. fasciatus 

 it is scarcely longer. L. 2^-4 mm. 



In decaying white-thorn, and also on firs and hazels ; local ; London district, rare, 

 Darenth, Forest Hill, and Ripley (Surrey); Portsmouth district; New Forest; 

 Lhmgollen ; Northampton; Repton, Bretby VVood (on firs, in some numbers and 

 very variable in size) ; Nocton near Lincoln ; Scotland, local, amongst old hazel 

 bushes; Sol way district; Stephens records it as common in the north and in Scot- 

 land, but I know of no localities in that country except the one last mentioned. 



MACROCEPHALUS, Olivier (Anthribus Schonherr). 



This genus contains one large and conspicuous European species which 

 may at once be known by the fact that the antennae are nearly as long 

 as the body in the male; it thus forms a transition between the Longicornia 

 and the Rhynchophora ; the rostrum is deeply incised at apex ; the third 

 joint of the antennae is. much longer than the second and the club is not 

 abrupt ; the eyes are emarginate ; the thorax has no distinct transverse 

 keel before base and the anterior coxae are evidently separated; the 

 species is found in rotten wood. 



IV. albinus, L. Oblong, subcylindrical, dusky brown, sometimes 

 almost black, with the rostrum, forehead, anterior margin of thorax, apex 

 of elytra and a larger or smaller spot on each towards suture thickly 

 covered with white scales ; extreme apex of elytra with a fuscous spot ; 

 antennae dark with the eighth and base of the ninth joints white; 

 thorax with the sides slightly rounded and narrowed in front, with three 

 tubercles on disc, arranged horizontally ; elytra with punctured striae, 

 coloured as above, and further with more or less distinct series of black 

 silken tufts, somewhat widened behind ; legs rather long annulated with 

 brown and white pile. L. 7-10 mm. 



Male with the antennae not or scarcely shorter than the body. 



Female with the antennae comparatively short, not reaching much 

 beyond base of thorax. 



In decaying trees, especially oaks, willows, and birches ; very local and, as a rule, 

 rare; London district, very rare, Ashford (Kent), Eltham, Darenth \Vood, Graves- 

 end ; formerly in Kensington Gardens ; Abbots Wood ; Folkestone ; Guestling near 

 Hastings ; Dorset ; Norfolk ; Bewdley Forest, where Mr. Stevens says it was formerly 

 common ; it does not, however, appear to have been met with by Mr, Blatch, who 

 has collected so much in this locality; abundant n*ar Newcastle (G. Wailes) ; in 

 Mr. Bold's catalogue there is a note to the effect that it used to be met with in 

 plenty at Gibside, but none have been taken for many years past; Mr. Wailes' speci- 

 mens are probably the ones referred to. 



PLATYRRHINUS, Clairville. 



This genus is represented by one large species, which is found in 

 fungi on old ash trees, and also in decaying beech, birch, and alder ; 

 it is the largest representative of the family that occurs in Europe ; the 

 antennae are short and terminate in a well marked three-jointed club ; 

 the eyes are round and entire and the rostrum is not bilobed ; the thorax 

 has a strong projection on each side a little behind middle and the keel
