224 LONGICORNIA, [ Callidium. 
C. alni, L. (s.¢. Pecilium, Fairm.). One of the smallest of the 
British Longicorns, short, rather shiny, pubescent; head black, antenne 
ferruginous ; thorax pilose, closely and distinctly punctured, with sides 
stronzly rounded, depressed at base ; elytra depressed, red and distinctly 
punctured at base, black and very finely punctured behind, with two 
white lunulate bands on each which nearly meet at suture; legs ferru- 
ginous, femora strongly clavate, with the club dark. L. 4-6 mm. 
Male with the antenne three-quarters as long as body, and the 
posterior femora curved; female with the antenne scarcely longer than 
half the body. 
In dead hedges and faggot stacks in woods, on flowers, &c.; local; London 
district, not uncommon; Darenth Wood, Peckham, Blackheath, Forest Hill, Shirley, 
Horsell, Coombe Wood, Maidstone, Westerham (in hop poles), Tonbridge, Sheerness, 
Chatham, &e.; Dover ; Glanvilles Wootton ; Llangollen ; Knowle, near Birmingham ; 
Oxfordshire ; Repton, Burton-on-Trent ; Cumberland; Northumberland district, 
Gibside, 
Cc. sanguineum, L. (s.g. Pyrrhidium, Fairm.). Oblong, depressed, 
black, clothed with thick and close and rather shining sanguineous 
pubescence, which gives the insect a bright scarlet appearance ; head 
nearly bare with only a few scattered scarlet hairs, antenne black ; 
thorax strongly angled at sides, with central line more or less bare; 
legs black, with femora clavate ; under-side black, with sides and apex 
clothed with reddish hairs; in the male the antenne are a little shorter 
than the body, and in the female they are considerably shorter. L. 
6-11 mm. 
Very rare; inold wood; Stephens records it from London and North Wales, and 
a fine series from Exeter; two specimens found in an outhouse at Plaistow, by 
Mr. Hindley (S. Stevens). I have a specimen in my collection given me by Pro- 
fessor Meldola, and sent to him by the proprietors of ‘* Land and Water” (to whom I 
believe it was sent to be named), but I do not know in what locality it was taken. 
CLYTUS, Laicharting. 
This genus is one of the largest and most important of the whole 
Longicornia ; it contains nearly four hundred species, which are widely 
distributed throughout the world both in tropical, temperate, and cold 
climates ; there are about thirty European species, of which three occur 
in Britain; they are distinguished by having the anterior coxal cavities 
transverse and very strongly angulated externally ; the thorax is scarcely, 
if at all, longer than broad, and the legs are very long, with the femora 
clavate but strongly petiolate; the species as a rule are brightly varie- 
gated with yellow or whitish bands ; C. arietis is one of our commonest 
Longicorns ; it is black, brightly banded with yellow, and in flight so 
much resembles a wasp that it is usually known as ‘‘ the wasp beetle.” The 
larve of C. mysticus and C. arcualus are described by Schiddte (Pars ix.
