410 RHYNCHOPnoRA. \_Scolytus. 



with the elytra dull, black, with the apex of the elytra more or less 

 broadly red, the latter sparingly pilose, very closely punctured, the 

 punctuation appearing almost uniform ; thorax comparatively coarsely 

 punctured on disc (the punctures being elongate), strongly and more 

 or less confluently punctured at sides ; abdomen dull, clothed with 

 thick ashy pubescence, gradually ascending from base to apex ; legs 

 ferruginous ; in the male the forehead is rather thickly villose. L. 

 2-2f mm. 



In decaying onk, cherry, apple, pear, elm. &c.* ; very local, hut not uncommon 

 where it occurs ; Esher, Netting Hill, Birch Wood, Diirenth, Whitstable, Forest Hill, 

 Caterham ; Isle of Wight; Monmouthshire and Herefordshire, abundant (Chap- 

 man) ; Bewdley ; Bromsgrove ; Cheshire. 



S. multistriatus, Marsh, (ulmi, Redt.). Black, shining, with the 

 elytra duller, pitchy-red, antennae and legs ferruginous, femora pitchy at 

 base; thorax longer than broad, very finely punctured on disc, more 

 strongly and closely at sides; elytra with close and regular punctured 

 striae, which are deeply impressed, interstices with regular rows of dis- 

 tinct punctures ; abdomen with the third to the fifth segments thickly 

 clothed with ashy pubescence, second ventral segment with a strong 

 horizontal projection on its posterior margin, which, according to some 

 authors, Eicbhoff among them, is confined to the male ; in the latter sex 

 the forehead is thickly villose. L. 2|-3j mm. 



In decaying elm, cherry, pear, oak, &c. ; local, but rather common where it 

 occurs; Mickleham, Birch Wood, Forest Hill, Merton (in plenty, July 8,3865, 

 size very variably (Power)), Dareuth, Esher, Wimble. 'on, Sheerness ; New Forest; 

 Monmouthshire and Herefordshire, common (Chapman); Bowdon, near Manchester, 

 rare (Chappell). 



This species is allied to S. intricatus, from which it maybe known by 

 its narrower form, more finely punctured thorax, and the more regular 

 sculpture of the elytra ; the shape and the sculpture of the elytra will 

 distinguish it from S. pruni, the interstices and the striae being evi- 

 dently more closely punctured ; it may, moreover, be separated from all 

 our other species by the structure of the second ventral segment of the 

 abdomen ; the tooth on the second ventral segment appears, from the 

 weight of authority, to be common to both sexes ; there is, however, a 

 variety, or possibly a separate species (recorded from Thuringia), S. 

 triornafug, Eich. in which the third ventral segment bears a sharp spine 

 behind the middle in the male only. 



HYLESININA. 



This tribe may be easily separated from the preceding by the even 



* Altum says that this species lives on Armeria vulgaris, although it occurs more 

 commonly under plum bark; Mr. Blandford, referring to Altum's statement, tells 

 me that he has taken a single example on Braunton Burrows, Devonshire, a locality 

 far from any plum trees, and close to the sea.
