NEW BRITISH SPECIES NOTICED IN 1860. 69 



closer, and the antennas with the antepenultimate articulation 

 acutely produced within, its apex deeply emarginate; the 

 penultimate likewise deeply notched at its apex, the terminal 

 slender. 



Messrs. Turner and Waterhouse have no claim either to 

 the discovery or first identification of this species. 



On the 21st of .June, 1849, I accompanied Mr. F. Smith 

 to an old oak in a hedge-row near Peckham, Surrey, in 

 which Mr. Ingall and himself had taken this insect,"^ and 

 where I succeeded in obtaining sevei'al examples, which I 

 referi-ed, as soon as they were set, to the D. chrijsomelina of 

 Sturm, which appellation they have ever since borne in my 

 collection. 



It will be seen by the references above given that this 

 insect was mistaken by Fabricius and others for the Dres- 

 dense of Herbst, and it appears to me that Stephens' descrip- 

 tion of B. Dresdensis, Illustr. Mand. iii. 337, i. (1830)— 

 his diagnosis is copied verbatim from the " Entomologische 

 Hefte" — applies to the species under consideration and not to 

 the true Dresdense, which is a much larger insect, of an elon- 

 gate quadrate form, vvith the thorax much nan-owed anteiiorly, 

 and of which no indigenous example has ever come under 

 my notice. The exponent of D. JDresdensis in the Ste- 

 phensian cabinet is a mere fragment, on a very suspicious 

 looking pin, sa?is head, sums legs, in fact sans everything.

 The genus Hhopalodontus was erected by the late M. 

 Mellie (Z. c. 233) for the reception of the present insect, 

 which diffei-s from Cis in having the tibias dilated and fur-
