LEPIUOPTERA, ETC., AT SCOTTISH LIGHTHOUSES 63 



place in England. Tutt, commenting on a presumed 

 immigration in May 1892, says, "we noticed then that many 

 of the specimens were exceedingly pale, a striking character- 

 istic of the south European examples which we have 

 frequently observed." Two Geometers {Hybernia defoliaria 

 and H. aurantiarid), both common here and in which the 

 females are "wingless" (a curious fact in this connection), are 

 also stated to pass over Heligoland in large numbers. 



Two further examples, and I have done with the 

 Lepidoptera. At daybreak on 27th June 1878, thousands of 

 Satin Moths {Liparis salicis) were seen to arrive at Harwich, 

 coming in from the sea ; they " resembled a fall of snow, they 

 were so numerous." On 27th March 1885, the sailing vessel 

 " Pleione," which was homeward bound from New Zealand 

 and had not touched at any port since leaving there, was 

 surrounded in about mid-Atlantic by a swarm of moths 

 identified from a specimen brought home as Deiopcia 

 pulchella many hundreds of which alighted on the ship. 

 The ship's position at the time was 440 miles from the 

 nearest point of the South American coast, and 960 miles 

 from the Cape Verde Islands, the nearest land in which 

 the species is known to occur (M'Lachlan, Ent. Mo. 

 Mag., 1885). Nearly related to our well-known Cinnabar, 

 and like it usually looked upon as a weak flier, D. 

 pulcJiclla is nevertheless not an infrequent immigrant on the 

 south coast of England, and has even been twice reported 

 from Scotland. 1 It, is common in the Mediterranean region 

 (many years ago I had the pleasure of seeing it at Gibraltar), 

 and with the above extraordinary flight on record, it is not so 

 very surprising that a few occasionally manage to reach our 

 shores. 



1 One near Aberdeen in 1S40, and one near Kelso in 1876 (see 

 Scot. Nat., x., p. 262, 1890).
