NEW BRITISH SPECIES, ETC., IN 1873. 101 



the punctuation of the elytra in front and on the disc vague, 

 and on the sides and behind very thick. Thomson (vrho 

 does not blindly follow other authors) considers the two as 

 very strongly separable, on account of 0. monticola having 

 transverse second and triangular third joints to the tarsi, 

 a more closely punctured rostrum (which is broader in the 

 middle), more dorsally depressed elytra^ and, in the $ , an 

 evident fovea before the apex of the otli ventral segment, 

 the tibioe more pubescent on the inner side, and with a 

 stronger mucro at the apex. 



It may not be out of place to note here the existence in 

 Scotland (both at Rannoch and Braemar) of a pretty variety 

 of the variable O. maurus (not exactly answering to the 

 recognized vars. comoselliis and demotus, Schon., or 

 Briicteri, 111., but very near them), in which the thorax is 

 more rounded outwardly than usual, the tibire are pitchy-red, 

 the elytra are much more finely and rather more remotely 

 punctate-striate, and with wider and flatter interstices, which 

 exhibit scarcely a trace of transverse rugosity, and are 

 adorned with conspicuous patches of greyish-yellow pube- 

 scence.

This insect, although from its lighter colour (the thorax, 

 especially, is often clear red) it may seem only to be an im- 

 mature stage of the type, is, however, apparently always 

 smaller, v/ith fuscous or rufo-testaceous legs, with darker 

 tips to the femora, the legs themselves rather longer and of 

 more feeble build, having the femoral tooth not so much 

 developed, rather longer antenme, and the punctuation of the 

 thorax apparently not quite so close. 



It is not uncommon near London ; and Mr, John Scott
