Widely but locally distributed in northern Europe. It has not yet 

 been recorded in Britain, but it is noted from Scandinavia. In France, 

 it is common in the centre and north : Boulogne-sur-mer, Fontaine- 

 bleau, Malesherbes, Episy, Bourray, Lardy, Cauterets, Amelie-les- 

 Bains, Monte-Dore, Montreuil-Bellay, lie de Re, Saint Mammes, 

 Pouligueu, Coulanges, Vincelles, Noirmouthiers, Nantes, Pornic, 

 Soissons, Saint-Genis-Laval, Allier, Senlis, Le Blanc, Creusot, 

 Valenciennes, and Lyons. In Belgium, it is common at Condroz, Lim- 

 bourg, Arlon Spa, Campine, Charleroi, Rouge Cloitre, Hesbayenot. 

 In Spain, it is quoted from Gayangos, Barcelona, and Parga, 

 and in Portugal at Condeixa. Search will probably record a large 

 number of new localities. 



10. Stauroderus bicolor, Charpentier. 



Extremely variable in colour ; green, red, purple, yellow, grey, 

 brown, or black ; this is the most abundant and generally distributed 

 European grasshopper, and is met with nearly everywhere, in a variety 

 of colours ; the student would do well to capture a number of its 

 varieties and carefully note the identity of structure and use this 

 species as a starting-point for the determination of others ; it is most 

 likely to be confused with the preceding species, but may be known by 

 the characters mentioned in the table.

Excessively common throughout Europe ; Norway, Sweden, 



Lapland, Denmark, England, Scotland, Ireland, Holland, Belgium, 



France, all over Spain, Portugal, Switzerland, Germany, and Austria.

Genius X : CnoRTrnpFus, Fieber. 

 Bolivar restores Fieber's name for Brunner's fifth group of Steno- 

 bdtln-K^, characterised by the nearly parallel carina? of the pronotum 

 and short and dilated mediastinal area of the elytra.
