Eedeagus broad, parallel-sided, except for a slight constriction in middle, apex 

 evenly roiinded, quite obtnse, side margins somewhat thickened. Length 

 2'75 mm. 



From L. calcaratasindL.triejjkei the present species is distiu^aushed 

 by its practically truncate base of thorax, smaller last joint of antennae, 

 and more strongly punctured stria; of elytra ; and from the former also 

 by its larger head, more rounded sides of thorax, and very different (^ - 

 characters ; and from the latter by its longer legs and narrower tibiae. 

 From L. curta, the only other nearly allied British species, it may be 

 knowai by its larger head, much narrower last joint of antennae, more 

 strongly punctured striae of elytra, and longer and more slender first 

 joint of posterior tarsi. From L. disti/iguenda, Fairm., which also has 

 a large head and truncate base of thorax, it differs in its larger size, the 

 longer antennae, the more contracted thorax, the more strongly punctured 

 elytral striae, the longer legs, and the much more bent posterior tibiae 

 in the cj. 



The aedeagus, too, is very distinct ; it is broader and more parallel- 

 sided, and more rounded at the apex than in any of the above species. 



Mr. W. E. Sharp took a pair of this interesting insect last year at 

 Forres, Inverness- shire. I submitted the (^ to Dr. Fleischer, who 

 returned it as L. calcarata v. nigrescens, in spite of the markedly 

 different characters given above. 



L. curta. — This is a rather broad species, with the sides of the 

 thorax strongly rounded in the middle, and distinctly contracted to the 

 base in typical examples. The elytra are nearly parallel- sided for 

 about two-thirds of their length, and sometimes appear to be dilated 

 behind ; in small specimens (and particularly in the var. donisthorpei) 

 they are shorter and more rounded ; the punctures of the striae are not 

 large, but are deep and placed very close together. The colour is dark 

 ferruginous, with the thorax generally darker. The club of the antennae 

 is hardly as broad as in the other members of the group, and the last 

 joint is not quite so narrow in proportion, so that this species may be 

 mistaken for one of the second group. It most closely resembles L. 

 picea, the distinguishing characters of which are given below, and 

 differs from dark specimens of L. duhia in having the thorax more 

 strongly rounded at the sides and contracted behind, and more strongly 

 ptnictured ; the tarsi are thicker, and the first joint of the posterior 

 pair is more strongly dilated at the apex. L. eurtoh appears to be not 

 rare in the Oxford district and near Hartlepool, where the type form 

 occurs, as well as the var. donisthorpei.
