laceous, deep blue, cyaneous-black, or black ; head diffusely punctured, 
antennz black, with the first joint coloured like the upper surface ; thorax 
short, narrower in front than behind, thickly and finely punctured ; 
elytra irregularly, thickly and rather strongly punctured, with an inter- 
mixture of finer punctures; legs metallic. L. 4-5} mm. 
Male with the last ventral segment truncate at apex and impressed with 
a small fovea.

London district, rather widely distributed ; Hastings; Holm Bush, Brighton ; New 
Forest ; Swansea; Barmouth; Dean Forest; Bewdley Forest; Burnt Wood, Staf- 
fordshire; Matlock; Teesdale (an entirely green variety taken by Rev. W. C. 
Hey) ; Northumberland and Durham district ; Scotland, local, Solway, Tweed, Forth,

Cc. goettingensis, L. Oval, violaceous, with the base of the 
antenne, the palpi, and the tarsi ferruginous ; head diffusely and finely 
punctured, antenne rather long ; thorax very transverse, with sides 
shghtly rounded, more narrowed in front in the male than in the female, 
thickly and finely punctured, sides more strongly punctured ; elytra 
thickly punctured, the punctuation being fine and consisting of larger and 
smaller punctures intermingled ; legs, except tarsi, obscurely violaceous.

error, as it has not been recorded from any of the more northern counties of Eng- 
land, nor does Dr. Sharp include it in his Scotch list.

very convex, of a bright golden-green colour, with the thorax, suture,
