Two ^ ppecimens, one taken by Mr. E. A. "Waterhouse, at Studley, 

 near Eipon, in May last, the other by Mr. Cliamjjion, taken at Ca- 

 terham, in June, 1873, have been returned to me by M. Henri Tournier, 

 of Geneva, as C. Barnevillii, a species new to our list. It is described 

 as much resembling G. Zehii, but of a constantly smaller size, with the 

 antennae always entirely testaceous, the thorax darker than the elytra, 

 which are more strongly punctured, and the shorter and less regularly 

 curved hind femoral spine of the male. This spine differs in develop- 

 ment in these two examples, so that I have been induced to examine 

 further specimens of C. Zehii, and can only come to the conclusion 

 that C. BarnevilUi is an undeveloped form of it, and not a good species. 

 As to size, I have examined undoubtedly ^ Zehii, only one line long (it 

 varies to over Ij liu.), as small as the smallest 5ar?ieye7Z/i' ; the an- 

 tennae are often entirely testaceous also in Zehii; the thorax is not 

 darker than the elytra in one of the two British BarnevilUi above 

 noted, and is often darker in Zehii ; I see no difference in the punc- 

 tuation ; and I find among Mr. Champion's specimens a ^ with the 

 spine intermediate in curvature and length between Zehii and Barne- 

 viUii, there being, moreover, a distinct difference in these respects 

 between the first mentioned two specimens, as above noted. 



PiiALAcnrs.— M. Tournier, who is still engaged upon a Monograph 

 of this genus and its allies, now considers the insect referred to as P. 

 Ihimhcrti, Tournier, Ent. Mo. Mag., ix, p. 37, to be a variety of P. 

 corruscus (I have further British examples). A very email fdrm of 

 P. corruscus, scarcely three-fourths of an English line long, has come 

 under my observation recently (in some numbers) ; this only differs 

 in size from the type. I have found another example of P. Brisouti, 

 mihi, taken at Deal, and several specimens of P. hrunnipes, Bris.,from 

 Bait marshes at Chatham and Sheerness, among some insects belonging 

 to iVIr. Champion. 



OLinnrs HELVETicus, Tournier, MS. 



A single example, taken by Mr. Champion at Caterham, in 

 July, 1872, has been returned to me with this nanu; l)y M. Tour- 

 nier. Its shining black colour, and rather evident elytral punctuation, 

 distinguish it from all known British species except O. particeps, from 

 which its broader and shorter form will suffice to separate it.
