248 LONGICORNIA. [ 



insects, with the elytra oval and convex, and the antennae very robust 

 and comparatively short, not reaching much beyond the middle of the 

 body ; the thornx is rather bluntly spined at sides ; the anterior coxal 

 cavities are narrowly closed behind, and the legs are rather short and 

 very stout; the average size is from about 12-15 mm. 



XiAIKIA, Fabricius. 



This genus only contains one species, which gives its name to the 

 whole family ; it is widely distributed in Europe, and is found very 

 locally in Britain in old willows ; it is a large and conspicuous species, 

 with the antennae shorter than the body, robust at base and tapering to- 

 wards apex, and widely distant at their insertion ; the thorax has a strong 

 spine on each side ; the anterior coxal cavities are closed behind ; the 

 elytra are broad, and the legs rather stout. 



The larvn of Lamia tertor is described and figured by Chapuis and Candeze (Lnrves 

 des Coleopteres, p. 245, pi. viii., fig. 1); it is broad in fivot and narrowed behind, 

 about 40 nun. in length ; Lend small, about a third as broad as prothorax ; prothorax 

 nbout as broad as meso- and metathorax, and as long as these two segments and the 

 first abdominal segment together; antennae very short; mni.dibles strong and tri- 

 angular; legs wanting; abdominal segments nine in number, with the first seven 

 furnished with a transverse oval furrow ; anal segment very small ; the lnrva lives in 

 old willows, where it changes to the pupal state, in which it remains for rather more 

 than a month before it emerges as the perfect insect. 



It. textor, L. A large and robust species, oblong, rather convex, 

 entirely of a dull fuscous black or black colour, with the under-side 

 moderately thickly clothed with yellowish pubescence ; head large, 

 eyes strongly divided, antennae stout, tapering to apex ; thorax trans- 

 verse, together with head closely rugose, with a sharp spine on each 

 side ; elytra broad, coarsely granulate (the granules being rather shiny), 

 and scantily powdered with dots of yellowish pubescence, which in 

 places are confluent, and are often more or less obsolete ; legs very stout 

 and comparatively short, black. L. 18-28 mm. 



Male with the elytra subtruncate at apex, and the scutellum rather 

 narrower than in the female, in which sex the elytra are obtuse at apex. 



In decaying willows ; rare ; Fair-light, Hastings (Butler); Hampshire; Bath and 

 Bristol (in this locality it has been taken in some numbers) ; Burmouth ; Scotland, 

 local and rare, amongst tallows, Argyle and Tay districts. 



IKONOCHAMMUS, Latrcille. 



The two species belonging to this genus which are reputed as British 

 are almost certainly importations ; as, however, they are retained in all 

 our catalogues, I have not omitted them ; the genus is a very large and 

 important one, containing more than a hundred species, which are widely 

 distributed from Siberia to New Guinea ; no species, however, appears to 

 have been described from South America, although one or two have
