spurs; metatarsi short; tarsi decrease from first to fourth ; fifth longer ; 

 ungues and three pulvilli large. PI. iii., fig. 6 b. Wings large and 

 broad. The costal does not reach the tip of the wing. First longi- 

 tudinal vein small and faint ; the second longer and more distinct ; 

 the third longitudinal simple, proceeding from the angle of the prce- 

 brachial transverse veinlet and meeting the costa at its tip ; fourth 

 and fifth longitudinal veins forked. 



The members of this genus are nearly all found in the spring and 

 early summer, the females are more sedentary than the males ; the 

 former may be taken in meadows and borders of woods by sweeping, 

 the latter are more often taken on the wing. The genus is repre- 

 sented in Britain by fifteen species.
