280 RHYNCHOPHORA. { Dorytomas. 
evenly rounded, closely punctured on the dise, ruzosely punctured to- 
wards the sides, and with a distinct, smooth, dorsal carina; elytra 
rather long ovate, with the shoulders a little elevated, the sides dilated 
and rounded, and with punctured striew, of which the punctures are 
close and rather large; legs rather short, entirely rufous or rufo- 
testaceous ; femora armed with a small tooth lL. 5-35 mm. 
On sallows; in June; rare; Wimbledon Common on dwarf sallows (S. Stevens) ; 
Wimbledon (Power); Coombe (one specimen, June 15, 1862 (Power) ); Yorkshire 
(Walton); Northumberland and Durham district, Hetton Hall, near Belford (W. 
B. Boyd). 
BD, majalis, Payk. According to Walton this is the smallest species 
of the genus, but on the average it does not appear to differ much in 
size from the two preceding ; it is closely allied to D salicis, from 
which it differs in having the rostrum not channelled, the thorax shorter, 
and the elytra darker, especially towards base; the colour, however, is 
very variable and cannot be relied upon, as in VD. salicis the elytra are 
sometimes more or less fuscous in front; the rostrum and thorax are 
also variably coloured, the former being entirely black or partly red, 
and the latter being dark, or reddish with a black patch, or entirely 
red; the thorax is slightly transverse, with the sides very little 
rounded ; the rostrum is rather long and stout, rugose, but without 
channels, and the elytra are variegated as in the allied species ; the male 
has the antenne inserted further in front of middle of rostrum than in 
the female, and the teeth of the femora stronger. UL. 2-3 mm. 
On the catkins of Salix cinerea, caprea, awrita, &c., in May and June; rare; a 
northern species; Northumberland and Durham distriet, Twizell and Castle Eden 
Dene ( Bold) ; near Carlisle (Heysham) ; Scotland, Solway district (Sharp); Walton 
mentions having received many specimens from the Rev. W. Little, taken by him in 
Scotland ; Stephens (Manual, 235), records it from the London district, but this is 
evidently in error; he appears to have confused the male of D. agnathus with the 
species (vide Waterhouse’s Catalogue, p. 75). 
In studying this genus it must be remembered that the general 
colour of the body is extremely variable, the dark species, if immature, 
being coloured previsely like the lighter ones ; this very much increases 
the ditficulty of their determination ; in some respects the genus, for its 
size, is the most difficult of all the British Rhynchophora. 
In many of the descriptions and notes on this and other genera I am 
much indebted to the valuable papers by Mr. Walton, published in the 
Annals and Magazine of Natural History for 1844. 
SMICRONYCHINA. 
This tribe, which contains the genus Smicronyz, is included by Bedel 
under the Erirrhinina, but differs in having the tarsal claws connate ; 
in this latter respect it agrees with the Lixina, from which it may be 
easily separated, apart from the very small size of its members, by
