TrachypkUetu.] RHYXCHOPHORA. 185 



T. laticollis, Boh. (sj_>inimanus } Thorns., ner, Germ.). Ovate, black, 

 antennae 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 striae, interstices level, each with a row of erect white 

 setae ; anterior tibiae with two not very strong teeth at apex ; the species 

 superficially resembles T. spinim.anus, from which the much shorter 

 armature of its anterior tibiae at once separates it, but it is more closely 

 allied to T. alternans, from which it may be known by having the elytra 

 distinctly striated, with level interstices, all moderately thickly set with 

 fine scale-like setaa, whereas in the latter species the striae are indistinct 

 and the alternate interstices only are setose, and somewhat elevated. 

 L. 2i-3 mm. 



Extremely rare ; Weston-super-Mare (five examples, Crotch) ; Scotland, extremely 

 rare, Sol way district (Sharp). 



T. spinimamiSj Germ, (nee Thorns, et Gyll.). Black, antennae 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 setae on each interstice ; anterior tibiae with a 

 long spine near the apex externally, and with two diverging spines in 

 front. L. 2|-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 

 stria? (if the crusted covering be removed) more distinct, the alternate 

 interstices only furnished with erect scale-like setae, and somewhat 

 elevated, and the spinose appendages at the apex of the anterior tibia? 

 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. 2|-2f 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, 

 Asbford, Eastry, Southend, Chatham ; Margate; Dover (common, J. J. Walker); 

 Folkestone ; Arundel ; Southsea beach, near Cumberland Fort; Sandown and Veut- 

 nor, Isle of Wight ; Portland ; Weymouth.

 but three or four are found in Europe, the others occurring in Algeria
