occupy the space where the carinse 

 would be if they were developed, and 

 have the appearance of carinas. 

 •5. Foveolse of vertex trapezoidal or 

 rhomb >idal, quite distinct; carinee 

 of pronotum obliterated in second 

 half of prozona, represented by 

 two yellow stripes forming a cross. 

 5.-5. Foveolae of vertex obtuse, tilled 

 in ; carinsB of pronotum more 

 or less angled, even in front of 

 typical sulcus, covered with 

 little tubercles . . 

 ii.'S. Discoidal area of elytra generally provided 

 with a thick intercalated vein, entire 

 and distinct, very rarely feebly developed, 

 in which case the metasternal lobes are 

 united behind the corresponding foveolse. 

 Metasternal lobes united behind ; foveolae 

 of vertex represented by almost tri- 

 angular spaces ; carinte of pronotum 

 straight ; wings rosy ; vena inter- 

 calata of elytra variable 

 Metasternal lobes distant ; foveolse of 

 vertex triangular ; vena intercalata 

 stout; wings hyaline, tinged with 

 greenish or bluish. 

 5. Vena intercalata of elytra situated 

 in middle of discoidal area, or 

 at least nearer to the radial than 

 to the ulnar vein . . 

 5.5. Vena intercalata of elytra nearer 

 to ulnar vein . .

Genus I: Acrida, Linn., Stal. [—Tri/.mlis or Tni.raiia, Fabv., 

 Brunner, et auctt.). 

 This genus, which is widely distributed in the Old World, is repre- 

 sented in southern Europe by two species, which are not difficult to 

 distinguish. The genus is unmistakable, on account of the large size 

 and curiously-shaped head, which is produced into a long and narrow 

 elevated cone, at the extremity of which are the eyes, and sword-like 

 antennte. 



Table of Species. 

 1. Elytra alike in each sex; mediastinal and scapular 

 areas opaque, irregularly reticulated, not dilated ; 

 carinae of pronotum straight and imrallel ; claws of 

 tarsi short, the pad equal to them in length, large, 

 dilated at the apex . . . . . . . . . . 1. nasuta, Linn. 



1.1. Elytra of o" with mediastinal and scapular area 

 dilated, hyaline, the transverse veinlets parallel 

 and regular ; lateral carinse of pronotum bowed ; 

 claws of tarsi a little shorter than the third seg- 

 ment, the pad compressed and very small . . 2. unriiiculata, Ramb. 



1. Acrida nasuta, Linn. { = tiirn'ta, Linn.). 



In this species the wings are tinted with green in both sexes ; the 

 general colour is green, or brownish, variegated with darker bands.

Fairly common in south Europe, it occurs also in Asia, Africa and 

 Australia. In the Iberian Peninsula it is found only on the east and
