SYNOPSIS OF THE ORTHOPTERA OF WESTERN EUROPE. 87 



N. ARCNDixETA, Schmidt, " Stett. Ent. Ztg.," xix., p. 369. — Larva: Shaped like 

 that of neurica, dirty white, back of a light reddish tinge. Upon tho 2nd and 3rd 

 segments are always eight line brown tubercles in a slanting row, upon the hack of 

 the following segments there are always four black tubercles occupied with one short 

 bristle. Spiracles white, edged with black, surrounded with three fine little black 

 warts ; similarly coloured very fine little warts on the outside of the light-coloured 

 hindlegs, studded with one row of brown hooks. Scutellum and anal plate brown- 

 grey, always with four larger and many smaller brown warts. Prolegs yellow-grey 

 with brown hooks. Head round, slightly curved, dark brown. Pupa : Brown- 

 yellow, slender, with the last segment rounded off, with two long diverging bristles 

 and two short little bristles, also two similar liner ones on the subdorsal portion of 

 the last segment. Lives in June in the stem of Phragmitea, and pupates in the lower 

 part of the stem, or in the old steins, at the beginning of July, placing itself head 

 downwards ; the emergence-hole below, with a web under and above itself forming 

 a puparium.

Genus III : Pterolepis, Bam bur. 



This genus resembles Gampsolceis in the somewhat long plantulae, 



but differs in the rudimentary and squamiform elytra, and slightly 



upcurved and sharply pointed ovipositor. In appearance it more closely 



resembles the genus Rhacocleis. There are two species known, both 



confined to Spain. 



Table of Species. 

 1. Posterior femora long and slender ; elytra <? not 

 covered by pronotum ; anal segment of <J termina- 

 ting in an obtuse triangular lobe, ending with two 



small spinules ; cerci strongly curved in d 1. spoliata, Rambur. 



1.1. Posterior femora shorter and stouter; elytra <? 

 almost entirely covered by pronotum ; anal seg- 

 ment of s prolonged in middle to acute and very 

 spiny triangular lobe ; cerci <? nearly straight, 

 but slightly curved at the apex . . . . 2. cokdubensis, Bol.

Smaller and darker, anterior femora with only two spines ; length

Recorded from Chiclana. 



2. Pterolepis cordubensis, Bolivar.

 shorter and nearly completely covered by the pronotum ; the posterior 

 femora are relatively shorter and stouter. Length of body, 26mm. $ ;
