sandy sliores of Norfolk, Suffolk, and Glamorganshire, it is found 

 abundantly during the months of May and June. It also occurs, as 

 I am informed by Mr. Dale, at Weston-super-Mare, in Somer- 

 setshire.

Ci. riparia. Megerle. — Steph. Catal. No. 3. 



In colour this insect greatly resembles the last (but it is considerably narrower^ 

 although longer) ; it is of a more dusky hue above^ with a very sUght cupreous 

 iridescence on the thorax : the elytra are shagreened^ each being adorned 

 with a slender white external lunule at the base, a broader one at the apex, 

 and a broad, nearly straight and slightly sinuated, white, transverse band in 

 the middle, reaching nearly to the suture. The under parts resemble those 

 of the last species, but the blue tinge predominates: the palpi are nearly 

 coloured as in it, but the basal joints of the labial palpi are of a purer white, 

 and the articulations of the maxillary palpi are less rufescent : the thighs are 

 very rich golden-green; the shanks cupreous, and the tarsi bronzed-blue. 



The disposition of the markings on the elytra agrees precisely 

 with those of Ci. Sylvicola, but the insect is clearly distinct from it, 

 and may at once be readily discriminated by its elongate shape, its 

 pale labial palpi and atropurpureous colour, exclusively of other 

 characters. 



The only indigenous specimen of this hitherto undetected species 

 which has come under my observation, and is in my collection, I 

 formerly conceived to be merely an extraordinary variety of Ci. 

 hybrida, but upon a mature examination its characters appear to 

 be sufficiently marked to constitute a distinct species ; and upon 

 referring to M. De Jean's Species de Coleopt^res, &c., I find that 

 he has described and figured an insect (as the Ci. riparia Me- 

 gerlei) agreeing in every respect with my specimen, whose " local 

 habitation," I regret, is unknown to me, from my having hitherto 

 confounded it with the preceding species. De Jean suspects that 

 it may be simply a variety of Ci. hybrida; but it is of importance 

 to bear in mind that the insect so called by him is totally distinct 

 in form, size, colour, and locality from the true Linnean hybrida, 

 his being an inland while Linne's insect is a maritime species. 



It affords me real gratification to add, from my own cabinet, a 

 second species of this truly elegant and lovely genus to our Fauna. 

 And I wish to call the attention of entomologists to the fact of the
