 2. Division Oxytellna . 

 Labial palpi are simple and normal; mandibles most often short, 

 occasionally however peculiarly strongly prominent; middle coxae nar- 

 rowly separated or contiguous; tarsi 5- or 3- or exceptionally only 

 2-jointed, tibiae, namely the foremost and middle ones, the outer margin 

 in most of the genera spiniferous. 



Key to Jenera. 



1. Fore and middle tibiae in outer margin spiniferous. (Subdiv. Qxytelina 



wuls. et Hey) 2. 



Fore and middle tibiae not spiniferous, only haired. (Subdiv. Tro- 

 gophloeina Muls. et Rey 8. 



2. Tarsi 3- jointed 3. 



Tarsi 5-jointed 7. 



3. Scutellum free before the elytra on the neck-shaped foremost part 



of mesothorax (Fig. 154). Fore tibiae most often with two rows 

 of spines in outer margin, at tip without incision. Antennae 

 after the long first joint strongly geniculate, and the head 

 with antennal groove beneath the eyes. The body rather cylin- 

 drical and often narrow, haired..... 91. Bledius Mannh. 



Scutellum not free, but as usual between the elytra. Fore tibiae 

 as a rule with only a single row of spines and most often with 

 incision at tip. Antennae feebly geniculate, and the head 

 without distinct antennal groove beneath the eyes 4. 



4. Middle coxae rather broadly separated 5.
