Range. S. Europe, Africa, Southern and Western Asia. 



General characters of Acrida, but the tegmina are differently 

 formed in the sexes. In the males the mediastinal and scapular 

 areas ai'e enlarged towards the middle of the tegmina, and their 

 spaces are usually transparent, and traversed by more or less 

 regular nervures ; the third radial nervure of the tegmina and 

 the first branch of tlic radial nervure of the wings branch 

 beyond the middle of the tegmina and the wings respectively. 

 The lateral carinas of the pronotum are ilexuous, and curve 

 upwards in front, being convex and divergent towards the 

 metanotum. The upper inner terminal spur of the hind tibiae 

 is one-half shorter than the lower inner spur; claws of the tarsi 

 sometimes half as long as the third joint of the tarsi ; arolium 

 small. Wings generally brightly coloured ; always wdth the 

 transverse nervures thickened.

 are t« o waved carinse on the upper part of the pleura, and on the 

 hinder half an oblique white one below them. Antennae broadly 

 flattened, tapering at the extremity. Tegmina narrow, pointed, 

 longer than the wings, green, with the costal area subhyaline, 

 especially in the male ; a brown bar, undulated above, and followed 

 by detached spots, runs longitudinally through the middle of the 

 M"ing ; the inner marginal area is often reticulated with reddish 

 in the male. Wings moderatel}^ broad, pointed at the tips,
