410 RHYNCHOPTIORA. [ 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 dise (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. IL. 
2-25 mm. 
In decaying oak, cherry, apple, pear, elm. &c.*; very local, but not uncommon 
where it occurs ; Esher, Notting Hill, Birch Wood, Darenth, Whitstable, Forest Hill, 
Caterham; Isle of Wight; Monmouthshire and Herefordshire, abundant (Chap- 
man) ; Bewdley ; Bromsgrove; Cheshire. 
S. multistriatus, Marsh. (w/mi, Redt.). Black, shining, with the 
elytra duller, pitchy-red, antenne 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 
strie, 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, Eichhoff among them, is confined to the male ; in the latter sex 
the forehead is thickly villose. L. 23-3} mm. 
In decaying elm, cherry, pear, oak, &e.; Jocal, but rather common where it 
occurs ; Mickleham, Birch Wood, Forest Hill, Merton (in plenty, July 8, 1865, 
size very variable (Power) ), Darenth, Esher, Wimbledon, Sheerness; New Forest ; 
Monmouthshire and Herefordshire, common (Chapman); Bowdon, near Manchester, 
rare (Chappell). 
This species is allied to S. intricatus, from which it may be 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. prunit, the interstices and the strie 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. 
triornatus, 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.
