156 SERRICORNIA. [ Malachtus. 
reddish ; legs rather long, dark, metallic, with tarsi sometimes pitchy. 
L. 6-7 mm. 
Male with the second joint of the antenne produced in a point inter- 
nally at apex, third joint armed at apex with a long curved hook, nearly 
meeting the produced process of second joint, forehead with a deep 
transverse impression in front, clypeus swollen. 
Female with the antenne and forehead simple. 
On flowers, &c., especially in woods; local; London district, rather common ; 
Darenth Wood, Woking, Horsell, Belvedere, Tilgate, Epping, Chatham, Sheerness, 
Southend, Tonbridge; St. Leonards; Gosport; New Forest ; Glanvilles Wootton ; 
Barnstaple ; Swansea ; Knowle, near Birmingham; Repton; Knutsford, Cheshire; 
Northumberland and Durham district, rare, Stockton and Newcastle ; the species has 
not, apparently, been found in Scotland. 
M. bipustulatus, L. Of a bright metallic green colour, rarely 
bluish, with the mouth parts yellow, and the apex of elytra, and the 
extreme anterior angles of the thorax, orange-red ; the extensible vesicles 
at the anterior angles of thorax are always visible in this species, and, as 
they are of a bright orange-red colour, they make the anterior angles 
appear more broadly red than they really are; head very finely punc- 
tured, dull; thorax transverse, with the sides and angles rounded, 
depressed at posterior angles; elytra feebly rugose, with very faint 
traces of raised lines; pubescence much as in the preceding species ; 
under-side dark, metallic, with sides of mesosternum yellowish-red ; 
legs metallic green. L. 5-55 mm. 
Male with the basal joints of the antenne whitish-yellow beneath, 
second joint furnished beneath with a large broad curved appendage, 
third joint small, with a projecting tooth, fourth joint with a large 
hooked process nearly meeting the process of the second joint, fifth joint 
somewhat dilated ; forehead with a deep transverse impression, clypeus 
swollen. 
On flowers, and by general sweeping; very common and generally distributed 
from the Manchester district southwards; it is, apparently, not uncommon in the 
Northumberland and Durham district, but Dr. Sharp records it as very rare in the 
Forth and Tay districts of Scotland; he has not apparently met with it at all in the 
Solway or Tweed districts. 
I. viridis, F. Very like the preceding in general appearance, but 
smaller, with the thorax subquadrate and not transverse and quite uni- 
colorous, and with the apex of the elytra only narrowly reddish ; the 
sexual characters, moreover, are very slight, the male only having the 
first joint of the antennz incrassate, and the rest simple, and the fore- 
head and clypeus somewhat swollen in front; the apex of the elytra is 
occasionally concolorous. L, 4 mm. 
On flowers, &c.; local; London district, rather common and generally distributed ; 
Whitstable; Margate and surrounding district; Deal; Brighton ; Portsmouth 
district ; Weymouth; Devon; Cambridge; Trench Woods; it has also been recorded 
from Carlisle.
