Genus I : Orphania, Fischer. 

 We have a single species of this genus in western Europe ; it is a 

 very large, fat, heavy, apterous, soft insect, almost invariably green in 

 colour, but varying somewhat in size ; it should be noted that the 

 hinder border of the side lobes of the pronotum are almost straight, 

 that is, there is no sinuation of a pronounced character ; a further 

 generic character is the great width of the frons between the antennae. 



1. Orphania denticauda, Charp. 

 Pale green, large and plump ; rarely reddish-brown, speckled with 

 darker. Length of body, 32mm.-34mm. ^ , 34mm. -38mm. ? ; of 

 pronotum, 10mm. -12mm. cJ , 10mm. -13mm. $ ; of posterior femora, 

 19mm. -28mm, J , 20mm, -32mm, j ; of ovipositor, 18mm. -27mm, $ . 

 This fine insect is found in nearly all the mountain regions of 

 central and southern Europe. In France, it is common enough in the 

 Vosges, also in the Alps and the Pyrenees ; in Wiirttemberg it is 

 numerous at Tiibingen ; in Switzerland it occurs near Neuchatel and 

 Morges, on the Eochers de Naye and the Waadtlander Alps ; in Italy 

 it is recorded from Tuscany. In Austria it is noted from near Vienna, 

 Kahlenberg, Liesing, Maur, Modling, Gaden, Purkersdorf, Schwarzau, 

 Gutenstein and Hohenberg. Also in the Tirol, 



The variety ILmnensis, Saulcy, has a furrow on the vertex, and more 

 spines on the anterior tibige ; it is recorded from Bagneres de Luchon,
