SYNOPSIS OF THE ORTHOPTERA OF WESTERN EUROPE. 231 



A native of northern Africa (Zanzibar, Abyssinia, etc.,) and eastern 

 Europe. In Italy it has occurred at Venice. Rudow records a 

 specimen (probably accidental) from Malchin in Mecklenburg. 



Genus IX : Sphixgonotus, Fieber. 

 This genus is characterised by the flattened pronotum, and whitish 

 velvety covering of the body ; the pronotum is strongly constricted 

 anteriorly, and the keel is almost or entirely absent. 



Table of Species. 



1. Wings blue, with no fascia 1. c;ekdlans, L. 



1.1. Wings blue, with a dark band or spot. 



2. Band of wings dark, smoky, indistinct . . . . 2. cyanopterus, Charp. 



2.2. Band of wings black, distinct. 



3. Pronotum almost smooth, with the central 

 keel hardly raised in the metazona, absent or 

 nearly so, in the prozona ; intercalate vein 



of elytra very near the radial 3. azurescens, Ramb. 



3.3. Pronotum rugose, with the central keel 

 visible throughout the length, cut by the 

 two transverse sulci. Intercalate vein of 

 elytra distant from radial 4. callosds, Fieb. 



SpmNGONOTUS c^rulans, L. 



This is the only species with no black or smoky band or spot 

 on the wings, which are tinted with blue. Length of body, 18mm.- 

 21mm. S- , 25mm. -27mm. $ ; of pronotum, 3-5mm.-4mm. <? , 5mm.- 

 5-7mm. ? ; of elytra, 17mm. -24mm. ^ , 27mm.-30mm. 2 . 



Found in stony or sandy places under a hot sun, in many 

 localities in southern and central Europe. In France it is commoner 

 in the south than in the centre ; it has been taken as far north as 

 Paris, also at Fontainebleau, and in all the southern departments, 

 and nearly all the centre. In Germany it has occurred at Mannheim, 

 Erlangen, Brieg in Silesia, Saxony; also in Bohemia; in Austria 

 near Vienna, Oberweiden, Marchegg, Modling, Steinbriick in Lower 

 Austria ; in Switzerland, in Valais, on the Lake of Geneva, on the 

 banks of the Aar in the Urserenthal ; also in Corsica and Sardinia. 

 Throughout Spain and Portugal. 



2. Sphingonotus cyanopterus, Charpentier. 



This is a northern form of the latter, from which it differs in 

 having a smoky band on the wings. Length of body, 17mm. J , 

 20mm. 5 ; of pronotum, 3-2mm. J , -Imm. $ ; of elytra, 17mm. 3 , 

 21mm. ? . 



A rare northern species, found in summer and autumn in hot 

 sandy places. In France it has been taken in the Forest of Fontaine- 

 bleau, in the valley of la Solle, Long Rocher, Rocher de Gros 

 Sablons and the forest of Ermenonville. In Sweden, in Gottland at 

 Stencumla ; also Appelsate, Bohuslan, and Tingstade. In Germany at 

 Liineberg, in Thuringia, the upper Harz and Glogau in Silesia. 



3. Sphingonotus azurescens, Rambur. 



Differs from the two preceding by the clearly marked black band 



on the wings ; the var, arenarins, Lucas, differs in having a vague 



spot instead of a band, but all the specific characters of this kind are 



of very doubtful value. Length of body, 17mm. -20mm. <? , 23mm.-
