off towards the posterior end. Viewed dorsally, the frontal head-piece 

 is scarcely visible, and only traces of the wing-cases can be seen, the 

 hindwings alone showing base of attachment. The mesothorax 

 extends backwards, in the shape of a wedge, into the metathorax, 

 causing this latter to appear much broader laterally than dorsally. 

 The hindwings, attached to the lateral angle of this segment, extend 

 as far as the 2nd abdominal segment. The antennas curving backward 

 are 2mm. apart immediately below the glazed eye ; from this point 

 they gradually converge, until, at 6mm. from the anterior end, they 

 meet and run parallel for a length of l-7mm. to the rear of the 4th 

 abdominal segment, ending apparently Hush with the wing-cases ; on 

 careful examination, however, they may be seen to be continued under the 

 surface of the 5th abdominal segment for a short distance. The maxilbe 

 are about 32mm. in length, ending at the junction of the antenna?. 

 On both the antenna? and maxilla? the sculpturing is very plain, and 

 consists, in the main, of transverse veins with small side branches; an 

 actual network is less apparent than on the other portions of the pupa. 

 The legs are rather indistinct owing to their veining being less marked 

 than on the antenna? and maxilla?. The first pair abut against the 

 eye and the antenna? — the former surface being much the broader — 

 and join the maxilla? at about half their length. The remaining space 

 is occupied by the second pair of legs. 



In conclusion, I may state that the average length of each instar 

 was twelve to fifteen days, and that emergence took place early in June. 

 This is naturally a period far in advance of the actual appearance of 

 the imago in its habitat, so that in all probability the growth and 

 development is much slower in nature than in confinement. 



Synopsis of the Orthoptera of Western Europe.

(Continued from vol. xviii., p. 329). 



Genus II : Amphiestris, Fieber. 



Distinguished from Locusta by the characters given in the table ; 



it is not likely to be confused with that genus. It contains a single 



species. 



1. Amphiestris b.etica, Rambur. 



Green, varied with yellowish, and darker ; pronotum spotted with 

 yellow; elytra green, with blackish network. Length of body, 31mm. 

 $ , 32mm. $ ; of pronotum, 7'8mm. $ , 9mm. $ ; of elytra, 10mm. 

 S , 5mm. $ ; of ovipositor, 23mm. $ . 



Occurs on shrubs in the south of Spain, at Malaga and in Anda- 

 lusia. Also in Algeria. 



Family V : Decticil\e. 



This is an important and extensive family, including a large 

 number of active and powerful grasshoppers in the temperate regions 

 of the Old and New Worlds. Southern Europe appears to be the 

 headquarters of the group, but a few isolated genera occur in South 

 Africa and Australia. 



All the genera have a well-marked family likeness ; they are active 

 and powerful insects, with especially well-developed hindlegs; the head 

 is more or less rounded, and the frons slightly enclined ; in the
