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 Schonherr 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, Cure, flavescens is 

 unquestionably (as he suspected) a pale immature variety of his 

 puncticollisy 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 Cure, 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 f ; 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 in 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 Schonherr 

 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-
