ACIDALIID.E—^TIMANDRA. 75 



This species seems to have been recognised as British from 

 very early times: Haworth describes it as extremely rare, 

 but gives no locality ; and Stephens agrees, adding that his 

 specimens were taken near Darenth, but he calls it Varir- 

 (jafn, Scop. ; and he supplies two localities in Cumberland. 

 which were doubtless erroneous. With the exception, there- 

 fore, of Stephens's locality, next to nothing was known of it 

 here till the years 1850 and 1S(jO, when a few specimens 

 were taken in the Warren, near Folkestone, Kent. Here it 

 was found to be, in some seasons, fairly common, and from 

 this locality our cabinets were supplied, and the eggs obtained 

 from which we have learned something of its natural history; 

 but with the unfortunate result that the insect has been 

 nearly exterminated in that district; by 1892 it had almost 

 totally disappeared. The only capture in any other locality 

 in these islands of which I have any knowledge is of a speci- 

 men — which I have seen — taken in 1876 on the ground which 

 is now the Alexandra Park at Hastings, Sussex. Abroad it 

 has an extensive range through Central Europe, Southern 

 and Western France, the northern half of Italy, Livonia, 

 Southern Russia, Dalmatia, Greece, Tartary, China, Japan, 

 and the Corea.
