5. Sroup Euaesthetini. 



( Euaesthetina Thorns. Skand. Col. Ill, 1861, 114. - Evesthetiens 

 Kuls. et Rey Erevip. 1878, 299. - Kuaesthetinae ianglb. Kaf. U. II, 

 1895, 542). 



Prosternum behind the fore-coxae is entirely chitinized, and pro- 

 sternal spiracula covered; antennae 11-jointed, inserted at base of 

 mandibles, under the corner of anterior margin of forehead far in front 

 of eyes, which are small, round, rather strongly protruding, and are 

 placed far back, at posterior margin of the head. Posterior coxae are 

 "tap-shaped", prominent posteriorly, only narrowly separated. 



The body of the European genera small; the head prominent and pro- 

 portinately large, with very short, broad neck or posteriorly scarce- 

 ly constricted; antennae short, clavate, inasmuch as the two (or more) 

 last joints are more or less strongly thickened; anterior margin of 

 labrum most often finely toothed; mandibles sickle-shaped; the last 

 (fourth) joint is unusual small, finely spiculiform, often hardly vis- 

 ible. 



Pronotum is most often heart-shaped; elytra rather short, hardly 

 reaching out over metasternum; legs short; coxae small, fore-coxae 

 rounded-conical, prominent and contiguous; tibiae without spines; all 

 tarsi 4-jointed. 



Of those to the group belonging few European genera only 1, Euaesthetus i 



-1.
