16 MANDIBULATA. — ORTHOPTERA. 



in the female with a long, straight, compressed ovipositor; both 

 sexes have two elongate, sharp, spiniform processes on the breast, at 

 the base of the anterior legs, and four other long and obtuse lobes 

 behind.

 Catal. 301. No. 3313. 



Bright grass-green; head shining, yellowish beneath the eyes, the vertex 

 rusty-brown, which colour extends in a rather broad fascia along the back 

 of the thorax, which has an abbreviated ridge behind, and some transverse 

 wrinkles j suture of the elytra, and sometimes the strong longitudinal 

 nervure, rusty-brown or testaceous; the elytra themselves, as also the 

 wings, much longer than the body, and extending in the female to the apex of 

 the ovipositor; abdomen brownish-green, or dusky, sometimes with yellowish 

 wrinkles ; ovipositor greenish, with the apex brownish ; antennae with the 

 basal joints green, the rest testaceous ; eyes brown; legs generally green. 



In some examples the legs are yellowish-brown, with the hinder femora green. 



A very common species in most parts of the country, especially in 

 grassy places by the side of woods, and in meadows, towards the end 

 of August and beginning of September. I have frequently taken it 

 in Battersea fields and near Hertford : it also occurs in the New 

 Forest and in Devonshire. 



Genus VI.— DECTICUS, Sermlle. 



Body stout and short ; forehead broad, very obtuse in front, glabrous ; eyes 

 sessile, not prominent ; antennce inserted in a cavity on each side, rather 

 shorter than the body, the two basal joints rather stout, the basal one the 

 most robust ; thorax flat above, with a longitudinal central ridge and one on 

 each side, the sides suddenly deflexed, the hinder margin produced and 

 rounded ; elytra not much longer than the body, rather suddenly deflexed 

 and maculated; the base at the suture flat, and in the males furnished with 

 an ocellar spot, transparent on the right elytron; wings short, rounded, tri- 

 plicate ; abdomen rather short and stout ; in the male with four styles at the 

 apex, in the female with two, and a longish more or less incurved ovipositor; 

 legs nearly as in Ph asgonura. 



The insects of this genus are shorter, but comparatively more 

 bulky than those of the foregoing, from which they differ in having 

 the head obtuse in front, the eyes sessile, the thorax flat above, and
