and most likely pener.il; it pp<ars to be more widely distributed bat less common 

 where it occurs than several of the other species. 



O. saliceti, Payk. This very small species differs from all the 

 others found in Britain in not having the posterior femora sensibly 

 dilated ; in this respect it resembles O. poi/idi, a larger species, which 

 occurs in Xorthern, Central and Southern Europe, and has been wrongly 

 introduced into our lists by Stephens (and on his authority referred to 

 Britain by M. Brisout), on specimens of O. stigma, in which the posterior 

 femora are comparatively slightly dilated ; subovate, black, rather 

 shining, slightly pubescent ; head opaque, finely punctured ; rostrum 

 shining, delicately punctured ; antennae red, Avith the club dark, inserted 

 a little behind middle of rostrum, funiculus seven-jointed ; thorax 

 scarcely transverse, convex, strongly and not closely punctured, with the 

 sides rounded, hardly narrower at apex than base ; elytra oval, much 

 broader than thoras, with very strong and deep punctured striae, inter- 

 stices almost narrower than the striae, convex and shining ; femora 

 black, tibia? and tarei red, the latter sometimes pitchy ; the species has 

 more the facies of TanysfJiynis than of an Orch-eates and certainly seems 

 distinct generically at first sight. L. H mm. 



On various willows and sallows (Salix cinerea, alba, caprea, &c.) ; local and, as a 

 rule, not common ; Putney (Champion) ; Snodland, Kent ; Wimbledon Common 

 (S.Stevens); Hammersmith (Power); Norfolk and Somersetshire (Stephens); 

 Portsmouth district ( Jloncreaff) ; Repton, Burton-on-Trent (W. Garueys and myself) ; 

 Chat Moss (Chappell) ; Southport (Reston) ; Northumberland and Durham district 

 (Bold) ; Scotland, local, on sallows, Solway, Tweed, Dee and probably other districts 

 (Sharp); Ireland, Glasuevin, near Dublin (ili-Xab's list); it appears to be very 

 scarce in the Midland counties, but to become commoner in the North. 



RHAIVIPHUS, Clairville. 



The members of this genus are small insects which closely resemble 

 Orchestes, but differ in having the antennae straight and inserted at the 

 base of the rostrum between the eyes, and the upper surface of the 

 body glabrous, and by the very short scape of the antennae the anterior 

 coxae are plainly separated ; about four are known, which all inhabit 

 Europe ; the larva of the single British species is found on the leaves of 

 various trees, willow, apple, cherry, birch, &c. 



R. flavicornis, Clairv. (putteorfll*, Herbst.). Obovate, rather 

 depressed, black, glabrous, slightly shining ; antennae ferruginous or 

 reddish testaceous, with the club, which is rather elongate, dark ; 

 scape very short, shorter than the first joint of the funiculus, which is 

 globose-ovate ; thorax transverse, narrowed in front, with distinct 

 punctuation, which is scanty, as a rule, on disc ; elytra with strongly 

 punctured striae, interstices narrow and flat ; legs entirely black, 

 posterior femora rather strongly thickened. L. l-l-k mm. 



On willows, cherry, birch, apple, &c. ; locally common throughout the greater 

 part of England and Wales; Scotland, local, Solway, Tweed, Forth and Moray 

 districts ; Ireland, Dublin, Queenstown, Waterford and probably general ; it appears 

 t o be f ouud in most localities in the Midland counties of England.
