 most often rather thickly bounded; middle coxae in Oxyporus very broadly, 

 in the rest more or less narrowly separated; legs rather short; fore- 

 legs in several genera equipped for digging and the fore- and middle- 

 tibiae then at outer margin more or less robustly spiniferous; tarsi 

 either all 5-jointed or all 3-jointed, in a single genus ( Thinobius ) 

 only 2-jointed. Sex-characters of various sort found in most of the 

 genera in OO • 



Oxytellni prefer for the most part damp ground, and many dig or 

 root in the mould of sandy earth, others seek nutriment at manure, 

 decaying stuff and the like. Of middle and North 3uropean species 

 (about 140) more than 50 are heretofore found in this country. They 

 fall in two divisions. The larvae of different genera ( Oxyporus, Bledius , 

 Platystethus , Oxytelus , Haploderus ) are known.

 Key to Divisions. 

 1. Last joint of labial palpi large, semicircularly dilated. Middle 



coxae very broadly separated 1. Division Oxyporina . 



Last joint of labial palpi normal. Ptliddle coxae more or less nar- 

 rowly separated or contiguous 2. Division Oxytelina . 



1. Division Oxyporina . 



Last joint of labial palpi semicircularly dilated; clypeus short, 

 evenly truncated; mandibles peculiarly prominently protruding; middle 

 coxae very broadly separated; tarsi 5-jointed, tibiae not spiniferous. 



To this only 1 genus.
