224 LONGICORKIA. [Callidium. 



C. alni, L. (s.g. Pivcilium, Fairm.). One of the smallest of the 

 British Longicorns, short, rather shiny, pubescent; head black, anti-nine 

 ferruginous ; thorax pilose, closely and distinctly punctured, with sides 

 strongly 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 antennae three-quarters as long as body, and the 

 posterior femora curved; female with the antennae 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, Blackheuth, Forest Hill, Shirley, 

 llorsell, Coomb*; Wood, Maidstone, Wester-hum (in hop poles), Tonbridge, Siieerness, 

 Chatham, &c. ; Dover ; Glanvilles Wootton ; Llungollen ; Knowle, near Birmingham ; 

 Oxfordshire; ilepton, Burton -on -Trent 5 Cumberland; Northumberland district, 

 Gibside. 



C. sanpruineum, 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, antennae 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 antennae are a little shorter 

 than the body, and in the female they are considerably shorter. L. 

 6-11 mm. 



Very rare; in old 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 iny 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.

This genus is one of the largest and most important of the whole 

 Longicoruia ; 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 

 larvae of C. mysticu* and C. arcuatus are described by Schiodte (Pars ix.
