The habitat of this variety is chiefly the West Coast of Italy, from 

 Genoa to Tuscany ; it is also known from Bologna, Elba, and Mt. 

 Meta, Terra di Lavoro. It has been reported by Camerano from 

 Naples, but the specimen has since been mislaid, as I am informed by 

 Count Peracca. .According to the latter the var. hrueggemanni occurs 

 in Liguria only near the sea ; on the hills, from 100 metres upwards, 

 only the ordinary grey brown typical form is found. In the Aruo 

 valley it follows the plain which extends inland rather far from the 

 sea, and it even extends as high up as Florence, where examples inter- 

 mediate between it and the typical form occur, as near Genoa. 



In the province of Eome it is replaced by the following variety, into 

 which it gradually merges.
