latter having a narrow, straight, longitudinal white line, 

 exactly in the middle. The punctuation of the thorax, 

 moreover, is stronger, and the striae of the elytra are more 

 evident.

 Mr. Crotch, as anticipated, withdraws this as a British 

 species ; and states it was re-introduced by him on receiving 

 a MS. list of Sitones from M. Allard, in which it was given 

 as distinct; and, knowing that there were specimens existing 

 in several British collections under its name, he imagined 

 they probably belonged to the true species; which, however, 

 appears not to be the case. 



All the so-called British lineellus seen by me are varieties 

 of tibialis: the true species of that name appears to be tho- 

 roughly boreal, very like small crinitus, but with less pro- 

 minent eyes, finer and more closely punctured thorax, elytra 

 contracted towards the base, more strongly punctured and 

 deeply striated, and with only a iew small very shoi't hairs at 

 the hinder extremity. 



From Mr. AValton's remarks it would appear that both 

 Gyllenhal and Schonherr were confused as to this species ; 

 some exponents of which, sent by those authors, were, in his 

 opinion, merely examples or varieties of tibialis.
