by white bands, which give the appearance of a cross on the pronotum ; 

 the distinct triangular spots on the upper side of the hinder femora

1. Stauronotus genei, Ocskay. 



Easy to recognise by its small size and bluish or yellowish posterior 

 tibite. Length of body, 12mni. 3' , 15mm. -17mm. $ ; of pronotum, 

 2-3mm. ^ , 3mm. ? ; of elytra, 10ium.-12mm. <3 , 13mm. -14mm. 2 • 



A southern species. In France, only in the south and southwest, 

 from July to November, Hyeres, Amelie-les-Bains, Cannes, Frejus, lie 

 de Re, Landes de Bordeaux, Carcassonne, Le Pouligueu, Bagnols, 

 Montauroux, le Reyran, Montpellier, and Porto Vecchio in Corsica. 

 In Spain and Portugal it is common nearly everywhere ; in Italy 

 probably common ; recorded from Venice. 



2. Stauronotus maroccanus, Thunberg. 



Extremely varible in size and colour ; the smaller variety resembles 

 S. hrericnllis, but difiers in the more vertical frons, the invariably 

 trapezoidal foveobe of the vertex and the hinder Icnees, which are always 

 pale in the <? ; generally, it is larger, of a reddish-testaceous colour, 

 with darker markings; the elytra always surpass the abdomen, are 

 snbhyaline, with dark spots, and reddish veins. Length of body 

 17mm. -28mm. <? , 20mm. -33mm. J ; of pronotum, 3-2mm.-5-8mm. ^ , 

 4-2nim.-7mm. $ ; of elytra, 12mm.-26niin. ^ , 15mm. -32mm. ? . 



A southern species, occurring in desert places. In France it occurs 

 •commonly along the Mediterranean littoral, from July to October ; 

 Hyeres, dunes of Vias and Cette, Ramatuel, Saint Tropez. It occurs 

 also in Sardinia, is common in Spain <ind Portugal, from June to 

 September ; also in Sicily. It sometimes occurs in such numbers as 

 to form a veritable pest ; this sometimes happens in Spain, though it 

 is not noted in Portugal ; in France, it was so numerous on the 

 Camargue in 1901, as to form a plague ; it is abundant in north Africa 

 and was the locust that formed the famous pest in Cyprus. 



3. Stauronotus brevicollis, Eversmann. 

 A small species, distinguished from its allies as noted. Length of 

 body, 12mm. -18mm. 3, 16mm. -19mm. ? ; of pronotum, 3mm. 3, 

 3-6mm.-4mm. 5 ; of elytra, 10mm. -13mm. ^ , I3ium.-15mm. J .
