and the tibiz and tarsi clear testaceous-red ; the finely punctured head 
and thorax will easily separate it from C. hortensis. L. 24-22 mm, 
Marshy places; by sweeping herbage, and in moss; very local, but occasionally 
not uncommon where it occurs; Wimbledon, Esher, Tilgate; Ashdown; Shipley, 
near Horsham; New Forest; Quy Fen, Cambridge (one specimen only (Power) ) ; 
Portland ; Manchester district (Chappell). 
C. hortensis, Fourc. (aridella, Payk.). Oblong oval, moderately 
convex, of a coppery bronze colour, not very shining ; head with strong 
aud very close punctuation, antenne dark with the base clear red (a 
character that will distinguish it from mature specimens of all our other 
species); thorax short, in the male almost twice as broad as long, in the 
female about half as broad again as long, with sides slightly rounded 
and narrowed in front, very thickly and rather deeply punctured ; wings 
present ; elytra more shining than thorax, and distinctly broader at base, 
with rows of rather strong punctures, the central ones being more or less 
irregular and double towards base ; legs testaceous, with all the femora 
dark. L. 2-2? mm. 
By sweeping herbage; generally distributed and common in the London and 
South-eastern districts, and probably from the Midlands southwards ; it apparently 
becomes rarer further north, and is only recorded from one locality in the North- 
umberland and Durham district, viz. ‘‘ Wooler Haugh, Mr. J. Hardy ;” Dr. Sharp 
only records it from the Moray district of Scotland, but is of the opinion that it 
probably occurs in several other localities. Ireland, near Dublin and Waterford. 
C. Sahlbergi, Gyll., nec Wat. Cat. Oblong-ovate, convex, of a dark 
bluish or greenish-blue colour, sometimes cyaneous or violaceous, and 
occasionally geneous green ; it resembles C. swbewrulea, from which it may 
easily be known by its more strongly punctured head and shorter and 
stouter antenne ; antennee dark with the base more or less red, the 
upper surface of the first joint and of the apex of the second, and some- 
times of the following, being dark ; thorax convex, closely and strongly 
punctured ; elytra a little broader at base than thorax, with coarse rows 
of punctures, the central ones being more or less irregular and double 
towards base, interstices very finely alutaceous, shining ; legs somewhat 
variable in colour, femora all dark, tibie and tarsi ferruginous or 
testaceous, clear or more or less infuscate. L. 2-21 mm. 
On Caren, and occasionally on the Cranberry (Vaccinium Oxycoccos); very rare, 
and often represented in collections by C. subcerulea ; it has been taken by Dr. Power 
at Quy Fen, Cambridge, and by Mr. Wiikinson and Mr. Lawson near Scarborough, 
and I found one specimen of the neous green variety at Westward Ho! * N. Devon, 
at the end of August or beginning of September, 1883; it has also been recorded 
from Wimbledon, Blackdown (Devon), and the Bollin Valley, Cheshire, but I have 
not closely examined any of these specimens. 
* Herr Reitter, to whom I submitted this specimen, is of opinion that it is a 
variety of C. hortensis, but the general form and appearance is certainly rather 
that of C. Saklbergi, and the colour of the basal joints of the antenne is also that of 
the latter species ; C. hortensis appears always to have the basal joints clear red,
