NEW BRITISH SPECIES, ETC., IN 1866. 67 



ceous aTitenn?E, and the thorax i-ather longer and distinctly 

 narrowed towards the base. 



27. Thinobius LINEARIS, (Waltl.) Kraatz, Ins. Deutschl. 



ii, 883, 2; D. Sharp, Proc. Ent. Soc. 19 Nov. 

 1866. 

 Found in Scotland by Mr. Sharp, in company with 

 Somalota suhtilissima (to which it bears a grifeat superficial 

 resemblance) among the clean sand at the banks of rivers 

 and lochs. I have also found it among some insects taken 

 by Mr. T. Wilkinson at Scarborough. 



28. Anthophagus pyren^us, Ch. Brisout de Barne- 



ville, in Grenier's Cat. Col. de Fr. et Mat. &c. 41, 

 54 ; T. Blackburn, Ent. Mo. Mag. vol. iii, p. 139. 

 Mr. Blackburn has (accompanied by remarks exhibiting 

 a most judicious caution) brought forward this species on the 

 authority of a few examples, answering to M. Brisout's de- 

 scription, and taken on Grayvel, Rannoch, in July last. 

 The distinguishing characters between A. fyrenceus and 

 A. alpinus given by him are that, in the former, the thorax 

 is a little more contracted behind, and, with the elytra, 

 somewhat more deeply punctured ; also that the head in the 

 male is more deeply emarginate, with the mandibles much 

 larger and more suddenly dilated at the base, and the 

 frontal horns longer, more slender, and inclined somewhat 

 outwards. 



Supposing Mr. Blackburn's insects to be identical with 

 M. Brisout's (though the characters given do not entirely 

 accord with the description), I should certainly be inclined 

 to consider them as merely well developed males of A. alpi- 

 nus; with which, in the present instance, they must have 

 been taken in company indiscriminately.
