In the characters of the tibiae, this curious little insect some- 

 what resembles Pachytrachelus but it belongs undoubtedly to the 

 great Pterostichide section of the family and in spite of the pe- 

 culiar form and armature of the tibiae I think it comes nearest 

 to the Trigonotomae and Ahaceti. Being unable to dissect the 

 mouth I am unable to give the ligular and other characters; 

 the very shallow and broad emargination of the mentum (a 

 character of the Trigoiiotomi a.nd Abaceli) is, however, perceptible 

 without dissection.

The second joint of the antennae being articulated on the 

 edge of the first, proves that this species belongs to Abacetus
