10 THE entomologist's RECORD. 



Synopsis of the Orthoptera of Western Europe. 



By MALCOLM BURR, B.A., F.L.S., F.Z.S., F.E.S. 

 {Continued from vol. xvi., p. 323). 

 Genus VI : Chrysochraon, Fischer. 

 Characterised by the pointed head, absence of foveola?, xevy slant- 

 ing frons, shining- colour, and long pointed horizontal subgenital plate 

 of the (? ; the elytra are short in the J , lobiform in the 2 , and the 

 wings abortive in both sexes, but examples with fully developed organs 

 of flight occur occasionally. 



Table of Species. 

 1. Larger ; pronotum rough ; hinder knees dark ; 

 elytra of ? lobiform, greyish, pointed ; upper 

 valves of ovipositor short, inflated at base, curved 1. dispar, Heyer. 

 1.1. Smaller; pronotum smooth; hinder knees same 

 colour as femora ; elytra ? lobiform, rosy, 

 rounded ; valves of ovipositor long, straight, 

 compressed . . . . . . . . . . . . 2. brachyptekus, Ocsk. 



1. Chrysochraon dispar, Heyer. 



Grey, shining. Length of body, 18mm. ^ , 25mm. $ ; of prono- 

 tum, 8mm. J , 6mm. ? ; of elytra, 10mm. -15mm. S , 7mm. -9mm. J ; 

 of wings, 3-5mm.-14mm. 3" , 3mm. -16mm. 5 . 



The 2 is easy to distinguish from the following species, but the <y s 

 of the two kinds resemble each other more closely. C. dispar may be 

 recognised by the rough pronotum and dark posterior knees. It occurs 

 in wood-clearings in central Europe. In France, it appears to be 

 commonest in the Paris basin, in the forests of Senart, Bondy, and 

 Saint Germain ; also at Langrange, Fontaine bleau, Episy, Males- 

 herbes, Mont Dore, Soissons, Marne, Nantes, Senlis, and Tarbes. In 

 Germany, it is common in Thuringia and the Hartz Mountains ; also 

 at Stettm. In Switzerland, it occurs, apparently, only round the 

 Lake of Geneva. It is found throughout Austria, near Vienna, com- 

 mon at Bisamberg, near Weidlingen, Mauer, Baden, Neusiedlersee. 

 It is unknown in the Iberian Peninsula. The fully-winged form is 

 exceedingly rare. Brunner records it from elevated dry places in the 

 Wienerwald. 



2. Chrysochraon brachypterus, Ocskay. 



Distinguished from the preceeding chiefly by the smooth pronotum. 

 Length of body, 18-5mm. -15mm. (?, 18mm. -22mm. $ ; of pronotum, 

 2mni.-3mm. ^, 3-6mm.-4mm. $ ; of elytra, 5-5mm.-14mm. 3, 

 3mm. -16mm. ? ; of wings, l-3mm.-13mm. 3, l-8mm.-16mm. 2. 



This is a mountain insect found in similar localities to the last, 

 but generally a little commoner. In France it is rarer, recorded from 

 Cauterets, the Jura, and Mont Dore. It does not occur in the north 

 of Germany. In the Tirol it has been found at Igls, near Innsbruck. 

 In Spain, it is represented by the variety intermedia, Bob, distinguished 

 by the pointed elytra of the 2 , discovered at Collsacabra at about 

 3300 ft. 



Genus VII : Stenobothrus, Fischer. 



We now come to the most difficult genera. Stenobothrus, sensu stricto, 

 as defined by Bolivar, corresponds to Brunner's first subdivision of the 

 genus in the wider sense. Bolivar has divided the old large genus
