Glanvilles Wootton; Devon; Monmouthshire; Llangollen; Barmouth; Trench 
Woods; Knowle, near Birmingham ; Repton; Dunham Park, Manchester ; Northum-

Waterford. 
XYLETINUS, Latreille. 
This genus cannot be confused with any other by reason of its short 
broad form, strongly serrate antenne, and strong elytral strie; it con- 
tains between thirty and forty species, of which twelve are found in 
Europe, and the remainder are very widely distributed, having been 
described from Siberia, North and South America, the Canary Islands, 
Ascension Island, and North Africa; our single British species is very 
seldom met with. 
X. ater, Panz. (serratus, Panz.; Sternoplus ater, Muls.). Oblong 
ovate, rather short and broad, black, dull, clothed with extremely fine 
greyish pubescence; head large and broad, with eyes prominent, antennze 
moderately long, black, with base red, strongly serrate; thorax broader 
than long, as broad at base as elytra, strongly narrowed in front, very 
finely sculptured ; scutellum rounded behind ; elytra broad, subparallel 
or with sides feebly rounded, with strong but rather feebly punctured 
strize; interstices very finely rugose ; legs rather robust, femora black, 
tibia and tarsired, L. 23-4 mm. 
Male with the antenne more strongly serrate than in the female; 
female larger than the male, with the last ventral segment of the abdomen 
furnished with two granules which are distant from one another. 
In decayed wood; rare; Charlton, Kent (Janson) ; Cobham (Stephens) ; Tonbridge 
(Horner) ; Ascot Heath, on old fence (S. Stevens) ; Cowfold (Power); Mickleham ; 
Hertford ; Shipley, near Horsham, and Rusper (Gorham); Spitchwick, Devon, in 
moss (Leach) ; Newark-on-Trent (Hadfield) ; in the latter locality it has occurred 
not uncommonly on old palings. 
LASIODERMA, Stephens. 
This genus contains about a dozen species, which are mostly found in 
Europe ; one or two, however, have been described from North America; 
they may be known by their finely, but distinctly, serrate antenn, 
coupled with the fact that the elytra are not striated; one species is 
reputed to be British, but it is almost certainly an importation. 
L. serricorne, F. (festacewm, Duft.). Oval, convex, short and 
broad, of a ferrugino-testaceous colour, rather shining, clothed with fine 
greyish pubescence; head large and broad, deeply sunk in thorax, 
antenne yellowish-red, with the first joint much enlarged, finely but 
very distinctly serrate ; thorax much broader than long, convex, even,
