NEW BRITISH SPECIES, ETC., IN 1869. 83 



in a former "Annual" as taken at Bristol and Gravesend. 

 It is of about the same size and colour as L. rnfiipenney but 

 is more slender than that species, with longer joints to the 

 antennas and a narrower and more densely and finely punc- 

 tured head. 



Erichson and Kraatz state it to be so like L. scutellare 

 (not yet recorded as British) that this dense punctuation of 

 the head, only interrupted by a narrow vertical smooth space, 

 is its only distinguishing character.

M. Fauvel, who informs me that he has seen the original 

 type of Mr. Crotch's species, is decidedly of opinion' that it 

 is only L. pallidum^ of a rather darker colour than usual, 

 and states that variations in this respect occur on the Conti- 

 nent. He does not, however, allude to the discrepancy in 

 the length of the elytra between these two insects. 



Tiie sexual characters are so strongly marked in this genus, 

 that an examination of them in a male of Z/. Jansoni would 

 surely suffice to settle the question of its specific value.

 I give the above synonymy on M. Fauvel's authority. 

 Supposing his determination to be right, and also that 

 Mr. Crotch's proposed deposition of Marsham's species 

 (1802), because the name is supposed to. clash with that of
