SYNOPSIS OF THE ORTHOPTERA OF WESTERN EUROPE. 



117 



Schreb. 



elytra are strongly abbreviated, or rudimentary and lobiform ; the veins 

 are almost or entirely obsolete. The classification of this genus is 

 difficult, since, as in many apterous genera, the characters are few 

 and the species many.

1. Aphlebia marginata, Schreber. 



This is the only species of the genus in which the elytra reach the 

 end of the abdomen in both sexes ; it is easy to recognise by the white 

 border to the black elytra. The J has the feet all black, except the 

 tarsi which are pale ; the $ has yellow feet. The var. erijthronata 

 has the pronotum red instead of black. Length of body 6-5mm. <? , 

 9mm. $ ; of elytra, i-Smm. 3 , 5mm. $ . 



This is strictly speaking an east European species, but occurs in 

 Italy at Naples, Messina, and in Sicily and Tuscany. The var. 

 erythronata occurs with the type at Naples and Messina. The type 

 form is found also in Corsica. 



2. Aphlebia maculata, ISchreber. 



Blackish ; elytra testaceous, rounded at the apex, with a large dark 

 spot ; the elytra surpass the abdomen in the 3 , and are shorter and 

 truncated in the $ . The rare variety schdfferi, Fischer, has the elytra 

 entirely black, testaceous only at the base ; the feet are black in the 

 3 , with the spines and tarsi testaceous ; in the $ they are testaceous, 

 the tibiaj dark towards the apex. Length of body 6'5mm. J" $ ; of 

 elytra, 5-6mm. 3 , 3mm. 5 . 



Common in July under dead leaves throughout Germany, but does 

 not occur south of the Alps, nor in the west (Belgium, France, etc.) ; 

 in Austria, near Petersdorf, Mauer, Kalenderberge, Modling, Bruhl,
