184 RHYNCHOPHORA. [Trachyphloeus. 
elytra, as a rule, appear to be darker and much less distinctly punctured; 
the anterior tibie are unarmed in front in both sexes. LL. 25-3 mm. 
Sandy and chalky places, in moss and at roots of Lotus corniculatus ; very local 
and, asa rule, not common; Shirley, Mickleham, Caterham, Box Hill, Crohamburst, 
Chatham, Faversham; Southsea ; Portsmouth, common at roots of grass in spring ; 
Sundown, Isle of Wight; Scarborough; Leland, Waterford (Power) ; Walton records 
it as ‘rather rave, oceasionally found on sandy banks on Windmill Hill, Graves nd ; 
also near Birch Wood, and Bishops Wood, Hampstead, in June;’’ he appears, how- 
ever, to have mixed this species and 7’. aristatus. 
T. scaber, L. (Lifoveolatus, Beck., sguamosus, Gyll.). The largest of 
our species, obovate, dull-brown, sometimes entirely covered with a 
greyish or whitish crusted covering, antennz and legs pitchy or rufescent ; 
scrobes plainly visible from above; thorax very transverse, not con- 
stricted at base, but broader at base than at apex; elytra with rather 
variable strie, interstices usually tessellated with fuscous and cinereous 
seales, furnished behind with small outstanding scale-like sete ; the 
thorax is, as a rule, compressed at each side with a fovea, but is vari- 
able both as to impressions and sculpture and the distinctness of the 
central channel, which is usually present ; according to Walton it may 
be distinguished from every other species “ by having the head invari- 
ably with a transverse striga or constricted at the base, and by the 
anterior tibia being armed in both sexes at their apices, externally and 
in front, with six minute spines.” L. 33-43 mm. 
In moss, &e. ; occasionally found in sand pits and by sweeping herbage ; also at the 
roots of low plants in sandy places ; loca! ; London district, and south-eastern and 
southern counties, common and generally distributed ; Somerset ; Bristol ; Barmouth ; 
Malvern; St. Faith’s, Norwich; Scarborough ; Northumberland and Durham dis- 
trict, rare, Hartlepool, South Shields, Hetton Hall, near Belford, and Tunstall 
Hill; Scotland, rare, tweed, Forth and Moray districts; Ireland, near Waterford 
(Power), 
T. scabriculus, L. (scaber, Schonh., nec L.). Much smaller than 
the preceding, obovate, fuscous black or brownish, thickly clothed with 
greyish scales, head depressed, thickly and rugosely punctured ; rostrum 
rather broad with a deep central channel; thorax very transverse, with 
an oblong fovea towards each side, finely and rugosely punctured, central 
channel obsolete, dise and sides with a few whitish scattered setz ; 
elytra with punctured striz, thickly clothed with narrow erect scale-like 
setae ; in grey specimens the elytra are somewhat tessellated, and there 
is a rather conspicuous white spot of scales on each elytron before middle 
near suture; apex of anterior tibiz with a strong tooth on outer-side and 
another (bifid at apex) in front; teeth small in female. L. 25-3 mm. 
In sandy and chalky places, in moss, at roots of grass and low plants ; common and 
generally distributed in the London and southern districts, but does not apparently 
occur in the midland counties or in Yorkshire, Lancashire, &c.; Northumberland and 
Durham district, very rare, ‘‘ Marsden’? Mr. J. Hardy; Scotland, rare, Solway and 
Tweed districts; Ireland, near Dublin; according to Walton it is ‘‘ certainly the 
most abundant insect of the genus,”
