THE CONVOLVULUS HAWK-MOTH. 3I 



the irregular way in which this migratory species visits our 

 islands, it will suffice to note the records only since 1S94. 

 Previous to that year it was common, more or less generally, in 

 1846, 1868, 1875, 1885, and 1887. 



In 189$ an invasion seems to have effected a landing in the 

 autumn, on the south-west coast, chiefly, perhaps, in the Port- 

 land district, where some tifty individuals were captured 

 between August 12 and October 7 ; twenty-three were caught 

 near Bournemouth in August and September ; sixteen were 

 taken at Christchurch, August 1 1 to October 2 ; and eight were 

 recorded from Milford. Several were reported from Devon, but 

 only two from Cornwall, although four larvie were found in 

 October at Port Wrinkle in the latter county. At Cork, in 

 Ireland, ten specimens were obtained in October. Eastward, 

 the captures in September were Norfolk (seven), Essex (one), 

 Lincoln (one). Odd specimens were taken here and there in 

 Kent, Surrey, and Herts. Several were reported from Gloucester- 

 shire, and one from South Wales. The northward extension 

 was evidenced by the capture of one example at Alnwick, in 

 Northumberland, in September, and of two in Aberdeenshire, 

 one as early as August 31, the other September 9. 



The moth was almost a defaulter in 1896, but in 1897 about 

 forty specimens were taken, twenty-seven of which occurred in 

 the Scilly Isles and eleven at Portland (August 14 to Sep- 

 tember 16. One example was reported from Yorkshire and 

 another from Sutherlandshire, both in September. 



A female was taken at Brighton, July 18, 1898, and in the 

 autunm of that year a good many specimens were obtained in 

 various parts of England but chiefly in the south. Portland 

 again heading the list with over fifty (August 4 to October 3) 

 and a number were taken in the Isle of Wight during September. 

 Captures in 1899 seem to have been only pretty good. Portland 

 twenty, August 25 to September 20, perhaps less than a dozen 

 in other parts of England and one in Scotland, all in September
