CATALOGUE OF ORTHOPTEROUS INSECTS. 



This obscurely-coloured species is easily distinguished by 

 its conical head, short legs, and rather thickened hind 

 thighs. The general colour is obscure brown, slightly 

 varied with buff and luteous. The head is conically ele- 

 vated in the hind part of the disc, the surface being armed 

 with acute granulations ; the face is marked with a small 

 triangular black spot. The antennae are long and slender, 

 multiarticulate, finely setose, the joints very short. The 

 pro- and mesothorax are slender and finely granulose. The 

 tegmina are small and ovate ; the median carina rather 

 strongly angulated between the middle and base ; the chief 

 veins are varied with buff and black spots ; they are not 

 straight, but slightly undulated throughout their whole 

 length. The wings are moderately large, stained blackish 

 brown, with the longitudinal veins somewhat darker-co- 

 loured ; the costal area is darker brown, the chief vein not 

 furcate, blackish, with numerous small luteous dots. The 

 abdomen is long, slender, and simple; the terminal segments, 

 especially the eighth, strongly elevated and angulated at 

 the summit, the ninth joint obliquely deflexed ; the three 

 terminal ventral segments are not swollen beneath, the 

 ninth extending beyond the extremity of the ninth dorsal 

 segment. The legs are slender and short, resulting chiefly 

 from the shortness of the tibia?, which are not so long as 

 the femora ; the hind femora are rather thickened and den- 

 ticulated along their whole length ; the basal joint of the 

 tarsi iu all the legs is about the length of the three follow- 

 ing joints united.

This species is at once distinguished by the great length 

 of the abdomen and the comparative shortness of the me- 



sothorax, with its recurved spines. The head is rather 

 flat and simple ; the three ocelli are very minute, but 

 distinct. The antennae are very long (at least 4 inches) 

 and slender. The prothorax is the same size as the head. 

 The mesothorax is about 2-i- times the length of the pro- 

 thorax ; it is rather narrower than the prothorax in front ; 

 its disc is rather flat, each side having about eight thin 

 acute recurved spines. The metathorax is oblong, wider 

 than any other part of the body, its hinder portion rather 

 longer than the anterior. The abdomen is long, narrow, 

 and simple (twice the length of the entire thorax) ; the 

 three terminal segments are widened (they have, however, 

 been crushed) ; the seventh and following ventral plates 

 extend only to about the middle of the eighth dorsal 

 segment. The anal styles are short and obtuse. The teg- 

 mina are short, broad, and subtruncate at the extremity. 

 The wings are large ; the anterior area pale dull green, the 

 median vein furcate ; the posterior area is pale brown, with 

 a large, somewhat triangular pale buff spot near the apex. 

 The legs are long, slender, and simple ; the femora finely 

 serrated ; the tarsi with the basal joint as long as all the 

 remainder together. The body beneath is pale and simple, 

 except the mesosternum, which has two rows of deflexed 

 spines. 



The pupa is smaller (3£ inches long), with the meso- 

 thorax similarly spined ; the rudimental tegmina are very 

 minute (about one line long), oval, and the rudimental 

 wings are subovate, 5-J lines long, touching each other along 

 the inner margin in the middle of the back.

This obscure species is distinguished by the granulose 

 surface of the anterior part of the body, and by the ante- 

 rior half of the mesonotum being armed with six small black 

 spines arranged irregularly in pairs. The head is oblong,
