and the club of tlie antenuse very broad. In well developed males the 

 tooth on the posterior femora is very large and sharp, but sometimes 

 in the female also it is exceptionally conspicuous and acuminate. At one 

 time I thought these specimens were undeveloped males with almost 

 straight posterior tibiye, but dissection proved them to be females. The 

 thorax is nearly always rather darker than the elytra, and may be much 

 more so (v. nigrescens, Fleisch.), or even almost black. 



L. triepTiei. — This is one of the most distinct species, recognised 

 by its broad roimded form, very large head, short antennae and legs, 

 and strong sinuation at the sides of the base of the thorax. Small 

 specimens of under 2-6 mm. occur, which seem to be a stiunbling- block 

 to many, but there should be no difficulty about them, as in these all 

 the distingviishing points appear to be accentuated. L. trlepliei is not 

 uncommon ; it is generally found, I believe, under fir trees, and has 

 been taken in great abimdance at Woking. 



L. macropus. — The J of L. macropiis differs markedly from the 

 same sex of L. calcarata, but the $ ? of the two species are sometimes ex- 

 tremely difficu.lt to differentiate. The colour of theantennal club seems 

 constant, although it is a little darker than the rest of the antennae ; it 

 is, however, never fuscous or parti-coloured as in L. calcarata. The 

 lower plate of the posterior femora always shows traces of an angle in 

 L. calcarata, but is quite rounded in L. macropus. The punctures of 

 the striae of the elytra are placed farther apart in L. macropus, and 

 their shape is slightly different. The latter species generally has the 

 third joint of the antennae more evenly cylindrical, whereas in L. calca- 

 rata it is distinctly narrowed at the base. L. macropus is a very rare 

 species, which, as far as I know, has only been taken in Kent, Surrey, 

 Hants and Berks. 



L. STENOCORYPHE, Sp. TIOV. 

 Oblong-ovate, ferruginous with head and thoi-ax darker ; head large, almost 

 as large as in L. triepkei, rather closely and distinctly punctured, with four larger 

 punctiires on forehead ; antenna? long, ferruginoiis with the club dark, the latter 

 broad, as broad as in L. calcarata, l)ut with last joint much narrower ; thorax a 

 little narrower than elytra, broadest at the middle, with the sides strongly con- 

 tracted before and behind, base with an extremely shallow sinuation at sides in 

 <J , truncate in ? , posterior angles obtuse, strongly and rather closely punctured ; 

 elytra twice as long as thorax, not much rounded at sides, stritB very strongly 

 and closely punctured, more strongly than in L. calcarata, interstices finely but 

 distinctly pimctured, alternate ones with a few larger punctures ; legs elongate, 

 tibiae narrow, tarsi long and slender. ^ . Under plate of posterior femoi-a with 

 a very small blunt lobe at the apex corresponding with the lobe on the upper 

 plate; tibiae with a double ciu-ve, and inwards near the apex as in L. cu7-ta;
