SURREY ORTHOPTERA. 51 



The long rod-like process of the clasper is longer in salinellus than 

 the elongate sole-shaped main portion of the clasper, and shorter 

 than that flap in contaminellus . Moreover, the rod-like process is 

 thicker in contaminellus than in salinellus. 



A long series of specimens from Flamenda, Deliblat, Hun- 

 gary, collected in June, 1909, by Mr. Geza Uhryk, and which did 

 not appear to me to agree with what I knew as contaminellus, 

 prove on closer examination to agree with salinellus from the 

 east coast of England, except in some minor points. The speci- 

 mens, taken all round, are larger than British salinellus, and 

 are less marked with black on the fore wing. The black streak 

 which is situated below the cell, and connects the two lines 

 extending towards the base, is much fainter in the Hungarian 

 specimens than in British ones, and the angle formed by the 

 outer line below the lower vein is much less prominent in the 

 former. Moreover, the patagia have fewer black scales on the 

 whole ; some females are altogether without black on the patagia, 

 and have also no black marginal dots on the fore wing. The 

 genitalia do not differ from those of British salinellus, except 

 that the rod-like process of the clasper appears to be a little 

 longer. 



A large series of both sexes taken in June, 1909, at Flamenda, 

 Deliblat, Hungary, by Mr. Geza Uhryk. (Type in the Tring 

 Museum.)

SUEREY ORTHOPTERA. 



(Earwigs, Cockroaches, Crickets, and Grasshoppers.) 



By W. J. Lucas, B.A., F.E.S. 



In the Orthoptera we have a particularly interesting group of 

 insects, since, with the exception of a few very primitive species, 

 which themselves have sometimes been placed with the Ortho- 

 ptera, this Natural Order probably contains the oldest insects 

 which have come down to the present geologic age. 



Those which breed in the British Isles are but thirty-nine, 

 while of these eight are not indigenous and are therefore not 

 usually to be met with under natural conditions. Casual 

 visitors, especially from amongst the Cockroaches, often appear, 

 but of course must not be looked upon as British insects. Out 

 of the thirty-nine some twenty-seven are at present known to 

 occur in Surrey.
