Germar's two genera Notaris and Dorytomiis are incorpo- 

 rated by Schonherr with his genus Erirhinus. I shall in part 

 adopt his views, but the typical species oi Dorytomi differ so 

 materially in their contour and in the great length of the an- 

 terior legs, especially in the males, that I shall still keep them 

 separate. The following are British species. 



Gen. 358. Ekirhinus: with all the tibiae curved. 

 1. Festucae Herh. — Caricis Thunh. 



Oblong, fuscous, densely clothed with cinereous scales, ros- 

 trum and legs reddish-ferruginous : 3^ lines long. 

 Gyllenhal says it inhabits the flowers of Carex acuta and 

 other aquatic plants in rivers and lakes.
