observations on Amblyopinus Jansoui, &c. 97 



curious genus. .Since I have liad the opportunity of dissecting 

 and carefully examining its anatomy, t am inclined to think that 

 M. Solsky is right in placing it in the Tachyporina and that it 

 should stand at the end of that Tribe, immediately preceded 

 by Tachinus. But this arrangement must depend upon the 

 comparative value of these two characters, viz. the insertion 

 of the antenna^, and the emarglnation of the labrum. If the 

 latter is the most important, the genus would belong to the 

 Staphylinina ; if the former, to the Tachyporina, to which last 

 it also shows affinity in other important points, especially in 

 the form of the labium, with its inimeuse paragiossa;, and 

 in the maxilla).
