230 Mr. J. Walton on the genus Sitona. 
tion. I find by a recent examination of the typical examples from 
the Marshamian cabinet, that the three synonyms, nigriclavis, 
longiclavis and flavescens of Marsham, belong to the next species, 
and not to the present ; and I regret to have led Schénherr and 
Germar in this instance into an error, which they have published 
on my authority ; it is therefore necessary to state, that accord- 
ing to the manuscript and collection of Kirby, Curc. flavescens is 
unquestionably (as he suspected) a pale immature variety of his 
puncticollis, and referred by him to Marsham’s ‘ Ent. Brit. no. 
212. without doubt; this was my authority. Germar supposed 
that his Sit. octopunctatus was identical with Curc. caninus of 
Gyll. and flavescens of Marsh., and therefore he published the 
former name without characters*. Sitones insulsus is described 
by Gyllenhal as specifically distinct + ; and it appears not to have 
been found hitherto in Sweden, whilst the following is plentiful 
in that country. 
This is a larger and more robust insect than S. flavescens, and 
differs by having the head broader, the front sometimes with an 
obsolete puncture in the middle, or a faintly impressed line, more 
or less abbreviated, never extending to the vertex; the vertex 
commonly has two pale spots and is more convex ; the thorax with 
three distinct pale lines, the lateral ones the broadest, and some- 
times flexuous, between which are two whitish spots placed trans- 
versely, rarely with two near the base, and two on each side an- 
teriorly ; the elytra distinctly longer m proportion to the breadth, 
obscurely lineated, the sutural and the second interstice on each 
elytron very frequently with interrupted fuscous or black streaks ; 
the legs longer and more robust, especially the femora. 
Generally distributed, but more plentifully in the south of En- 
gland ; it occurs in Yorkshire, but I have never seen a specimen 
reputed to have been found in Scotland.

British specimens of this insect were forwarded to Schénherr 
and Germar with the name Sit. canina of Stephens ; the former 
referred them to “ Sitones octopunctatus},” and the latter pub- 
lished the following observations: “ Sitones octopunctatus, Schonh., 
may probably be only a variety of Sitones insulsus, Schonh., punc- 
ticollis of Kirby and of Stephens, from which it is only distin-
