MALE IMAGO (PI. XV, fig. 3). --In general bright 

 green in colour, except along the middle of the dorsal 

 aspect of the body from tip of head to end of abdo- 

 men, this being dull crimson. Length some 13 mm. 

 Head greenish, dull crimson dorsally, with the vertex 

 produced considerably between the antennae as a 

 flattened vertical plate. An ten nse, very long and slender. 

 Pronotum rounded, without carinaB ; an inflated spot, 

 resembling 1 a small bubble at the hind margin of 



O O 



each flap ; a broad, mid-dorsal, dull crimson stripe. 

 Prqsternum with two spines. Eli/trn nearly hyaline 

 particularly in the costal region, in the middle region 

 pale reddish brown with brown nervures ; acute ; 

 produced at the anal angle ; shorter than the abdo- 

 men. U7///-/X considerably shorter than the elytra, with 

 brownish nervures. Fore cox% with a long curved 

 spine. Fore tibise without spines ; tympana almost 

 hidden. Hind ///'///'long, slender, with two apical spurs 

 above and four below. Hind femora swollen towards 



*/ 



the base, then very slender ; without spines below. 

 Anal segment with two prominent blunt teeth, hiding 

 the supra-anal plate. Cerci stout, pointed, rough, with 

 a curved tooth near the tip. Styles short, straight. 



FEMALE IMAGO (PL XV, fig. 4). --Colour i 'nn similar to 

 that of male. Length some 14-16 mm. Elytra reduced 

 as in male. Wings reduced far more than elytra. 

 Cerci not toothed. Ovipositor, nearly 8 mm. long ; pale 

 brown ; gradually turned upwards ; slightly crenulated 

 at the tip. 



EGG. --One egg which I possess (extracted from the 

 body of a female) is pale in colour and therefore 

 probably not ready to be deposited. It is cylindrical 

 with rounded ends, and somewhat more curved and 

 slender than those of Locustids already noticed. Still 



/ 



it quite preserves the " family-likeness."
