SYNOPSIS OF THE ORTHOPTERA OF WESTERN EUROPE. 69 



the species is somewhat difficult, and the synonymy is rather confused. 

 One species, A. florezi, Bol., is characterised by having the presternum 

 unarmed, but yet it requires, provisionally at least, to be ranged in 

 this genus. 



Table of Species. 

 1. Prosternum unarmed, with no spines . . .. ..1. florezi, Bol. 



1.1. Prosternum with two spines. 



2. Plantulse about as long as the first tarsal segment.

3.3. Ovipositor curved downwards; lateral vein 

 of elytra <? blackish ; left elytron a with 

 no tympanal area . . . . . . . . 3. kradssi, Bol. 



(nee Brunner). 

 2.2. Plantula? much shorter than first tarsal seg- 

 ment. 

 3. Elytra a about as large as broad, the outer

1. Antaxius florezi, Bolivar. 



Chiefly characterised by the unarmed sternum, though possessing 

 the other characters of the genus ; dark chestnut or greyish- fuscous ; 

 the side flaps of the pronotum have a black spot in front and behind, 

 and a short white stripe behind ; the posterior femora have a broad 

 black stripe on the outer side, and are not spined beneath. Length of 

 body, 20mm. ? ; of pronotum, 5mm. $ ; of elytra, l-5mm. $ ; of 

 posterior femora, 17mm. ? ; of ovipositor, 15mm. ? . 



This species was recently discovered by Bolivar on an excursion 

 from Puerto de Leitariegos to the Monastery de Hermo, in Spain. 



2. Antaxius spinibracchius, Fischer. 



Dark greyish ; pronotum with side flaps black, entirely bordered 

 with yellow ; hinder femora not spined ; cerci of male with the 

 internal lobe broadened from the base to the inner tooth ; subgenital 

 lamina of female sulcate in the middle ; the veins of the elytra of the 

 male are brighter than the ground colour, and the left elytron has the 

 tympanum developed ; anal segment of the male with an angular 

 excavation in the middle ; ovipositor quite straight, longer than the 

 body. Length of body, 19mm. $ and $ ; of pronotum, 5-5mm. $ , 

 6 - 5mm. $ ; of elytra, 4 - 5mm. J , 4mm. $ ; of posterior femora, 

 17mm. J , 20mm. $ ; of ovipositor, 21mm. $ . 



Widely distributed through Spain and Portugal; the species seems 

 to be variable, and has been discussed by Pantel (An. <h la Soc, 

 A'*//, de Hist. Nat., xxv., p. 103).
