His division Fossores, therefore, comprises the sub-genus 

 Blediusy and the species congenerous with O.fracticornisj from 

 both of which the habits of Siagonium are entirely distinct, as I 

 have shewn in my former Paper. And with reference to the note 

 placed after 0. bicornis, it is evident that if the figure in Ahrens' 

 Fauna referred to be a correct one, and that species really be the 

 same as our quadricorne, Nicolai has inadvertently introduced it 

 amongst his Fossores, with which group it has not the slightest 

 connexion. Should, however, Ahrens' figure be that of a true 

 Btedius, Nicolai cannot have seen the figure of Siagonium in the 

 Introduction to Entomology. 



With regard to the number of eyes in the Larva; of the Brack' 

 elytra, and which I had considered to be four, two being placed 

 on each side of the head, I have to add that it is not easy io 

 ascertain distinctly their number in dark coloured specimens, 

 since they appear as irregularly formed minute tubercles. In one 

 which I possess, having the head lighter coloured than usual, I 

 perceive on each side, (behind the insertion of the antennae), four 

 of these tubercles placed in an irregular square, and of a black 

 shining colour.

At page 60, I have observed that I was not acquainted with 

 any author, who had figured the Larva of any of the Staphi/linidce. 

 I was not aware, however, at the time, that, notwithstanding Mr. 

 Marsham and Mr. Walford's opinions upon the subject, snbse-
