434: RHYNCHOPHORA. [ Pityophthorus. 
lum small, depressed, shining ; elytra as wide as thorax and less than 
twice as long, with humeral angles rounded, sides straight to near apex 
which is bluntly rounded, moderately shining, with rows of rather deep 
punctures, interstices impunctate, the inner ones subrugose transversely, 
especially round scutellum; sutural stria impressed throughout its 
lenecth; apical impressions wide and deep, with their central portion 
elabrous and shining, and their lateral margins abruptly raised and 
bearing five or six setigerous tubercles, as also do the sutural margins 
which are slightly raised at the apical declivity; underside thinly 
pubescent ; femora and tibie pitchy brown, tarsi and antenne testa- 
ceous. L, 2-21 mm. 
Under bark of Scotch firs, &c.; rare, Scotland, Dee and Moray districts, 
Braemar, &c. 
The points in which this species appears to differ from the continental 
P. Lichtensteinii are its greater size, the more abundant and yellower 
frontal pubescence, the greater narrowing of the thorax in front, and its 
more sparse and less rugose punctuation behind; these hardly seem, 
however, to be sufficient to justify its separation as a distinct species. 
P. pubescens, Marsh. (ramulorum, Perris ; micrographus, Brit. Cat. 
nec Gyll.). Somewhat elongate, pitehy or pitchy-ferruginous, shining, 
with thin grey pubescence, antenne and legs testaceous or reddish, 
femora and tibize sometimes with a fuscous tinge ; head in female with 
a conspicuous brush of greyish-yellow hair ; thorax as long as, or slightly 
longer than, broad, narrowed towards apex, which is rounded, scabrous 
and dull in front, finely and sparingly punctured and shining behind, 
with asmooth central line, the punctures being large and deep, base 
distinctly bordered ; scutellum distinct; elytra cylindrical, with con- 
spicuous rows of strong punctures, interstices with slight transverse 
wrinkles, sutural stria not impressed, suture slightly raised at apex with 
a narrow, somewhat rounded, depression on either side, the lateral walls 
of which are only slightly raised and are punctured by the continuation 
of the striz of the elytra and are not furnished with conspicuous setigerous 
tubercles. L. 13-15 mm. 
Several authors assign the villose forehead to the male, but it appears 
to be characteristic of the female. 
In dead branches of Scotch fir; local, but common where it occurs; London 
district, Kent and Surrey, not uncommon; Kew, Shirley, Esher, Forest Hill,

myself in early summer in great abundance from small twigs collected from the 
ground under fir trees in January; Leominster; Repton ; Burton-on-Trent; Ire-

species.
