Genus II : Ukomenus, Bolivar. 



This genus contains fourteen species, of whieh only two occur in 



Europe, but between these two there reigns great confusion. Serville 



originally described, under one name, forms from Sardinia and from the 



Pyrenees, but the characters he gives are common to the two forms. 



The synonymy is consequently very confused. We will follow Bolivar 



is retaining Serville's original name for the Sardinian species, and 



applying Bolivar's name to the Spanish species. 



Table of Species. 



1. Subgenital lamina ? with short triangular lobes; 



cerci c? cylindrical, obliquely truncate at apex and 



toothed there . . . . . . . . . . . . 1. rugosicollis, Serv. 



1.1. Subgen. lamina 2 with attenuate triangular lobes; 



cerci cT conical toothed at the base . . . . 2. durieui, Bolivar. 



1. Uromenus rugosicollis, Serville. 



Green ; pronotum very rugose, hinder margin with a broad 

 triangular emargination. Length of body, 24mm. <? , 28mm. $ ; 

 of pronotum, 7'5mm. J , 8mm. ? ; of anterior tibia?, 8mm. <? , 

 12mm. 5 ; of posterior femora, 21mm. <? , 20mm. ? ; of ovipositor, 

 14mm. ? . 



Found in Sardinia (Serville), and Corsica (Mus. Vienna) and also 

 in Algeria. The records of this species from southern France probably 

 apply to the following species, although Finot refers them here. 



2. Uromenus durieui, Bolivar. 



Closely resembles the preceding, but the pronotum is much more 

 smooth and convex ; the anterior tibiaj are shorter, the cerci of the <? 

 are longer : the lobes of the subgenital lamina of the $ are longer and 

 more slender, and the cerci of the ^ are longer and more cylindrical. 

 Length of body, 31mm. <? , 32mm. ? ; of pronotum, 8-3mm. 3 , 

 8mm. 2 ; of anterior tibife, 9mm. 3" , 10mm. $ ; of posterior femora, 

 17mm. 3 , 17-5mm. ? ; of ovipositor, 12-5min. 5 . 



Fairly common in Catalonia ; recorded by Bolivar from Tordera 

 and Calella ; taken by the writer at Vildarau, on Monseny near 

 Barcelona ; recorded by de Bormans from Beziers in southern France ; 

 also the records from Perpignan, Eoussillon, Caraman (Haute-Garonne) 

 and Toulouse probably refer to this species. 



Genus III : Steropleurus, Bolivar. 

 This genus consists chiefly of species inhabiting northern Spain, 

 but there are some species in Ital}" and northern Africa. 



Table of Species. 

 1. Metazona of pronotum very convex, with carinse 

 absent or almost obsolete. 



2. Lower border of side Haps of pronotum straight ; 

 supraanal plate d round. (Ovipositor long.) 

 3. Cerci j with a black apical spinule ; Catalan 



species .. .. .. .. .. ..1. catalaunica, Bol. 



3.3. Cerci <j with only basal tooth ; Italian 



species 2. cavann.e, Targ.
