202 SEHRICORNIA. [Lycfu*. 



Europe ; the remainder are widely distributed, representatives being 

 found in North, Central, and South America, Ceylon, New Zealand, Ac.; 

 they are narrow and elongate insects, and are found on freshly cut wood, 

 in and about old stumps, &c. 



I. Thorax very closely granulated, dull, with distinct central 



furrow L. CANALICULATPS, F . 



II. Thorax rather closely and coarsely punctured, with central 



furrow less distinct, often more or loss obsolete . . . . L. BB0NNEU8, StfpA. 



It. canaliculatus, F. (ollongus, 01. ; unipunctatus, 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, antennae 

 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 

 distinct ; 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 ; striae 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. 



Zi. 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, which 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 antennae, moreover, are more slender, and terminate in a narrower 

 club. L. 3-5 mm. 



In old oak stumps ; occasionally on oak palings ; very rare ; Norwood (S.Stevens); 

 Forest Hill (Marsh) ; Brockley ; Dulwich (in wasps' nest, Stephen*) ; bunks of 

 Lea ; Crystal Palace ; it has also been taken in Oxford Street by Mr. Watcrhouse j 

 Nottingham (one specimen in a shop window).
