Trachyphleus.] RHYNCHOPHORA. 185 
T. laticollis, Boh. (spinimanus, Thoms., nee Germ.). Ovate, black, 
antennz and legs brown-red, closely covered with grey scales; rostrum 
and thorax even; thorax very broad, with sides strongly rounded 
and a broad deep curved transverse impression near apex; elytra with 
distinct punctured strie, interstices level, each with a row of erect white 
sete ; anterior tibie with two not very strong teeth at apex ; the species 
superficially resembles 7. spinimanus, from which the much shorter 
armature of its anterior tibize at once separates it, but it is more closely 
allied to 7. alternans, from which it may be known by having the elytra 
distinctly striated, with level interstices, all moderately thickly set with 
fine scale-like setee, whereas in the latter species the striz are indistinct 
and the alternate interstices only are setose, and somewhat elevated. 
L. 23-3 mm. 
Extremely rare ; Weston-super-Mare (five examples, Crotch) ; Scotland, extremely 
rare, Solway district (Sharp). 
T, spinimanus, Germ. (nec Thoms. ef Gyll.). Black, antenne and 
legs red-brown ; upper surface covered with a thick white or lighter or 
darker brown crusted covering, which almost completely hides the 
obsolete interstices ; rostrum flat; thorax very transverse with sides 
rounded, constricted in front, without central furrow ; elytra with the 
alternate interstices sometimes very slightly raised, and with a series of 
small clavate scale-like setze on each interstice ; anterior tibie with a 
long spine near the apex externally, and with two diverging spines in 
front. L. 23-3 mm. 
Chalky hill sides; at the roots of Helianthemum vulgare; very local, but common 
where it occurs; Chatham (taken by Mr. Champion and Mr, Walker in great profu- 
sion in various parts of the district); Hampstead ; Mickleham; Southend ; Sheppy ; 
Dover ; Arundel; Southsea beach, near Cumberland Fort; chalk hill, near Ports- 
mouth ; Walton records it somewhat doubtfully from Cromer, Norfolk. 
T. alternans, Gyll. Closely allied to the preceding, but with the 
strie (if the crusted covering be removed) more distinct, the alternate 
interstices only furnished with erect scale-like sete, and somewhat 
elevated, and the spinose appendages at the apex of the anterior tibiz 
smaller: the rostrum is almost as broad and rather longer than the 
head, and finely channelled in the middle ; the thorax is short, transverse, 
narrowed and transversely impressed in front, much dilated and rounded 
at sides, without central furrow; elytra ovate ; legs pitchy or dark 
testaceous. L. 23-2} mm. 
Chalky hill sides; in moss, and at roots of Helianthemum vulgare ; occasionally 
by sweeping herbage; very local and, as a rule, not common ; Box Hill, Mickleham, 
Ashford, Eastry, Southend, Chatham; Margate; Dover (common, J. J. Walker) ; 
Folkestone ; Arundel ; Southsea beach, near Cumberland Fort; Sandown and Vent- 
nor, Isle of Wight; Portland; Weymouth.

This genus contains rather more than twenty species, of which all 
but three or four are found in Europe, the others occurring in Algeria
