202 SERRICORNIA. [ Lyctus. 
Europe ; the remainder are widely distributed, representatives being 
found in North, Central, and South America, Ceylon, New Zealand, &c.; 
they are narrow and elongate insects, and are found on freshly cut wood, 
in and about old stumps, We.

IJ. Thorax rather closely and coarsely punctured, with central 
furrow less distinct, often more or less obsolete. . . . UL. BRUNNEUS, Steph. 
L. canaliculatus, F. (oblongus, Ol.; uwnipunctatus, Herbst.). 
Elongate, subcylindrical, narrow, somewhat depressed on upper surface, 
of a lighter or darker brownish or reddish-brown colour, with the head 
and thorax sometimes a little darker, and sometimes a little lighter than 
the elytra ; head rather large, with eyes large and prominent, antenne 
ferruginous, rather short and robust, with strongly marked 2-jointed 
club ; thorax quadrangular, a little longer than broad, gradually and 
slightly narrowed behind, with the front angles blunt and the hinder 
angles sharp right angles, sides finely crenulate, central furrow broad and 
distinet ; the pubescence on head and thorax is yellowish-grey, rather 
thick, and the upper surface is very thickly and finely granulose and 
dull ; scutellum small; elytra long, parallel-sided, with the shoulders 
strongly marked, square, in darker specimens lighter than the rest of the 
upper surface ; striz fine and finely punctured, interstices very finely 
punctured, with regular rows of short upright hairs ; legs ferruginous, 
rather slender, first abdominal segment much longer than the following. 
L. 3-5 mm. 
On fresh oak palings, also on and about trees, and under bark, especially of oak 
and beech; local, but occasionally abundant where it occurs; Lee, Greenwich, 
Mickleham, Norwood, Croydon, Dulwich, Forest Hill, Tonbridge; common in parts 
of Kent on hop poles; Wroxham, Norfolk; Windsor; Birmingham; Repton; 
Church Stretton ; Dunham Park, Manchester ; Northumberland and Durham district, 
on oak wood, rare; Mr. Blatch informs me that it abounds in Birmingham in ash 
wood used for spade and other tool handles, gun-stocks, &c., and does immense mis- 
chief to both the raw and finished materials; one manufacturer showed him a pile of 
handles which had been completely destroyed by the borings of this beetle. 
L. brunneus, Steph. (Xylotrogus brunneus, Steph.). Closely allied 
to the preceding, which it much resembles in general appearance, but 
easily distinguished by the sculpture of the thorax, whieh is rather 
coarsely punctured and not granulose, and has the central furrow much 
less marked and more or less obsolete ; the head also is finely punctured, 
and not granulose as in L. canaliculatus ; the thorax is more widened in 
front, and the pubescence is more sparing and finer both on this part 
and on the head, and the rows of hairs on the elytra are less marked ; 
the antenne, moreover, are more slender, and terminate in a narrower 
club. L. 3-5 mm. 
In old oak stumps ; occasionaliy on oak palings ; very rare ; Norwood (S. Stevens); 
Forest Hill (Marsh); Brockley; Dulwich (in wasps’ nest, Stephens); banks of 
Lea; Crystal Palace; it has also been taken in Oxford Street by Mr. Waterhouse ; 
Nottingham (one specimen in a shop window).
