Several examples of this little species were taken by Mr. Dale and 

 his son at Freshwater, in the Isle of "Wight, on the 5th of November, 

 when the frost was on the ground. It appears to be perfectly distinct 

 from any previously described species, and comes nearest to ohsoletus of 

 Stephens, but is at once to be separated therefrom by its more robust 

 form, by the black markings on the head, thorax and abdomen, and by 

 the much stronger and intensely black antenna), which in the (the 

 only sex I have seen) , are more strongly pilose ; from Jiavidus of 

 Stephens it is abundantly distinct, vide Ent. Mo. Mag. vol. iii, p. 271. 

 It is not a little surprising that so small and delicate an insect should 

 resist a temperature below freezing point.

Notes on four additions to the list of British Coleoptera. — The following species 

 are entitled to places in our Catalogue : — 



1. Amarafusca, Dej. 



I possess an example of this species, given me by Arthur Adams, Esq., who 

 captured it at Swansea. It is allied to A. ingemui, and was presented to mo under 

 that name. All the British specimens of A. ingenua that I have seen are really 

 4. /usca, and come from the same source as my own. Dawson, however, records 

 A. ingenua as occurring in Scotland ; but I have never seen a Scotch specimen ; 

 and, if the species be really indigenous, it must be of the greatest rarity. A very 

 good description of A. fusca will bo found in the Ins. Deutschlands, vol. i, p. 537.
