its eggs upon a plant of potato growing by the side of a Skimmia bush, 

 on which it was ovipositing. 



From 11 a.m. to 2 p.m. seems to be the usual time both for E.

Synopsis of the Orthoptera of Western Europe.

{Continued from vol. xviii., p. 185). 



Genus II : Poecilimon, Fischer. 



This genus contains a large number of apterous, plump species, 



generally green in colour, of medium or small size, and mostly very 



locally distributed ; the genus is characterised by the transverse sulcus 



of the pronotum being situated before the middle, and by the hinder 



margin of the pronotum being rounded. The distinction of the species 



is very difficult, but there are only four recorded from western 



Europe, and these are quite distinct.
