MIGRATORY LOCUST. 251 



The very remarkable insect which is shown in Wo(»dcnt 

 XXV. Fig. 2, may be known by the exceedingly small size of the 

 wings and elytra, which in the female are practically absent, 

 and in the male are exceedingly small, not extending one- 

 fourth along the bod}'. 



Its name is Thamnotrizon cinereus, and the name is a very 

 appropriate one. It is composed of two Greek roots, the first 

 signifying a garden, and the other, to sing, or ratlier, to trill, 

 and is o-iven to the insect on account of its habits of sinijinu- in 

 gardens. The colour is brownish or rather grey, wliich in the 

 male is marked with dark brown. The colour is altogether 

 darker in tlie male than in the female. As is often the case 

 with insects of this order, the males are comparatively rare, so 

 that the capture of a perfect male Thamnotrizon may be looked 

 upon as an event in an entomologist's day. The insects are 

 found in gardens, or sitting among logs and brushwood, and 

 they also frequent fir woods. 



We now pass to the true Locusts, of which we shall take one 

 example. In these insects, the antennae are comparatively 

 short, and the female is without the sword-like ovipositor. On 

 Woodcut XXV. Fig. 1, is shown the well-known Migratory 

 Locust {Pachytylus migratorius). The name Pachytylus is 

 composed of two Greek words, one signifying thick and tlie 

 other a knot or hump, and is given to the insect because the 

 front of its forehead is rather projecting, and very hard and 

 thick. Some authors give it the name of (Edipoda, or Swollen 

 Leg, on account of tlie enormous dimensions of the thighs of 

 the hind pair of legs. 



This fine insect is very variable in point of colour, but is ge- 

 nerally as follows : — The colour is pale brown, the elytra being 

 simply spotted with dark brown. The wings are very large and 

 shining, and have a slight green tinge. The legs are brown, 

 banded alternately with black and yellow, as shown in the illus- 

 tration. The thorax is covered with fine down. 



This insect is happily very rare in England, and, although a 

 few specimens make ^heir appearance almost annually, the insect 

 has never fairly acclimatised itself. Daring tlie summer, news- 

 paper paragraphs are plentifid, annovmcing the capture of the 

 Locust, and describing its dimensions. Many of these insects
