240 CLASS INSECTA. 



culation, narrowed into a point at the end. The mandibles 

 are advanced a little beyond the labrum. The tarsi are 

 identical in the two sexes. 



The anterior extremity of the head forms a small muzzle. 

 The upper part of the body is plane, with the corslet trape- 

 zoid, almost as broad as the head, and a little narrowed 

 posteriorly.

 Our second general division of this tribe (Subulipalpi) 

 is distinguished from the preceding by the form of the ex- 

 ternal palpi, of which the last articulation but one, in the 

 form of a reversed cone, is united with the following, and 

 comprises with it a common ovaliform, or fusiform body, 

 terminated, either insensibly or suddenly, in a point, or oval- 

 like form. The two anterior legs are always emarginated at 

 the internal side. These insects resemble the last very much, 

 both in forms and manner of life. 



Bembidion, Lat. Bembidium, Gyll. Dej. 



Have the last articulation but one of the external palpi 

 large, swelled, and somewhat cone-formed, and the last 

 much more slender, very short, conical or acicular. The 

 first articulation of the two anterior tarsi is dilated in the 



males. 



M. M. Ziegler and Megerle, have divided this sub-genus 

 into many others, but without giving the characters, and 

 restino- solely, as it appears, on the changes of form in the 

 corslet.-f-
