Dallington Forest, Hastings ; New Forest ; Lords Wood and Shirley Warren, 

 Southampton ; Portsdown Hill. Portsmouth ; Devon ; Swansea (somewhat doubtful) ; 

 Llangollen (on oak and hazel) ; Forest of Dean (on chestnut) ; Bewdley, Sutton 

 Park, Birmingham, Robin's Wood, Repton and other midland localities ; Burnt 

 Wood, Staffordshire ; York ; Ripon ; Scarborough ; Delamere Forest ; Northumber- 

 land and Durham district, rare, near Gilsland and at Twizell ; Scotland, rare, Tweed 

 and Forth districts ; it probably occurs in Ireland, but I do not know of any record ; 

 this species seems very generally distributed, especially in the Midland counties, and 

 is recorded by many collectors as common, but 1 have never yet seon it alive. 



EHYNCHITINA. 



This tribe contains a few genera of which by far the most important is 

 Rhynchites ; its members are distinguished from the Attelabina by 

 having the external border of the mandibles cut out into large teeth, and 

 by the free tarsal claws, which in most cases are appendiculate, and also 

 by the fact that the* epimera of the mesosternam almost reach the 

 intermediate coxae and the apices of the prosternal epimera either meet 

 or are separated by a small and narrow centro-sternal piece ; the proster- 

 num is very short before the anterior coxae ; a large number of the 

 species are brilliantly coloured and very conspicuous insects ; our three 

 British genera have been by many authors united under Rhynchites, 

 but must be regarded as separate. 



I. First ventral segment of the abdomen lobed on each side 

 between the posterior co\se (the outer portion of which is 

 covered and concealed) and the side pieces of the ineta- 

 sternum ; upper surface glabrous or only finely pubescent 



towards apex of elytra BYCTISCLS, Thotns. 



II. First ventral segment of the abdomen not lobed, so that 

 the posterior coxae appear larger and more transverse and 

 visibly attain to the s ; de pieces of the metasternum ; upper 



surface pilose or pubescent. 



i. Apices of prosternal epimera meeting ; abdomen with 

 the pygidinm only erposed ; vertex of head not or 

 scarcely constricted behind RHYSC KITES, Schneid. 



ii. Apices of prosternal epimera narrowly separated by a 

 centro-sternal piece ; pygidium and propygidium as a 

 rule exposed * ; vertex of head large, strongly con- 

 stricted behind DEPORACS, Lench. 



BVCTXSCT7S, Thomson (JRhinomacer, Geoffroy, nee F.). 



The species belonging to this genus may be distinguished by the 

 formation of the posterior coxae and of the first ventral segment of the 

 abdomen ; the thorax is subglobose and is armed on each side in the 

 male with a long produced spine ; the upper surface is glabrous or almost 

 glabrous ; they are found on various trees; the female rolls the leaves 

 into the form of a cigar and lays her eggs in the dwelling thus con- 



* In Deporavs mannerheimii, as pointed out by Dr. Sharp, the male has only the 

 pygidium exposed (Trans. Ent. Soc. London, 1889, Part I. p. 70.)
