154 THE entomologist's record. 



common everywhere, especially in the north, the Alps and Pyrenees; in 

 England, somewhat local, but recorded from Eadley, near Oxford, 

 Dormans in Surrey, Folkestone Warren, Newquay, in Cornwall ; in 

 Spain, common everywhere, except, perhaps, the extreme north. 



8. Tettix bolivaei, Saulcy. 



Differs from the above in the less prominent vertex, and edges of 

 hinder borders of pronotum raised into a little keel. 



A doubtful species, recorded from Azam, Aude, Dieuze, Lorraine, 

 and the Basses-Alpes, in wet fields. 



9. Tettix fuliginosus, Zetterstedt. 



Larger ; dark, with black spots ; pronotum somewhat flat, with a 

 black triangular band on each side ; central crest gibbous, near base, 

 but elsewhere slightly elevated, the hinder part easily surpassing 

 posterior knees ; all femora with undulated keels ; hinder femora with 

 four black spots above ; first segment of posterior tarsi with pads quite 

 straight underneath, the third pad longer than the first two together. 

 Length of body, 11mm. ? ; of pronotum, 15mm. $ . 



Only the female appears to be known of this rare species, which is 

 distinguished, among other things, by its size. It occurs at Alten in 

 Norway, and Umeii and Toruea in Lapland, also in Siberia. 



10. Tettix ceperoi, Bolivar. 



Allied to T. suhulatas, but the anterior femora have the edges 

 undulated. Length of body, 6mm. -9mm. ^ and ? ; of pronotum, 

 8mm. -10mm. ^ and 2 ■ 



Southern Spain ; according to Azam, fairly common in France ; 

 Basses-Alpes and Var, Ille-et-Vilaine, Sologne, and the Loire- 

 Inferieure, Metz. 



Genus II : Paratettix, Bolivar. 



Distinguished from Tettix by the narrower vertex, which is not 

 produced between the eyes. One European species. 



1. Pahatettix meeidionalis, Rambur. 



Pronotum rather flattened, the crest distinctly gibbous, abruptly 

 depressed in front, the hinder part easily surpassing hinder knees ; 

 wings very ample ; all femora, especially the middle pair, with 

 undulated edges. Length of body, 6-5mm. ,3" , 11mm. ? ; of pronotum, 

 10mm. 3 , 13-5mm. $ . 



Common in southern Europe ; in France, the imago is met with 

 nearly all the year round in the south, generally in swampy places ; 

 all Portugal and all Spain ; Corsica, and in eastern Europe and the 

 Caucasus. 



Letting in the City. — Some Notes on the Rhopalocera of the 



London District. 



By ALFRED SICH, F.E.S.
