The cliief interest of these notes, apart from the night movement 

 of V. cardui, lies in the fact that they indicate almost unlimited possi- 

 bilities in the way of an interchange of insects of various orders 

 between the south-eastern shores of England and those of the Con- 

 tinent. Some of the fortuitous migrants named are of extreme 

 delicacy, and that they should have been wafted so far across the 

 waters of the North Sea was a matter of great surprise to me. 



Many other insects came on board during my sojourn, and I wish 

 it had been possible to pay more attention to them, but T was much 

 otherwise engaged with the investigations which were the main object 

 of my visit to the Lightship.

[It appears to us impossible to over-rate the importance of Mr. 

 Eagle Clarke's notes, so far as the nocturnal migration of F. cardui is 

 concerned. If our Entomologists would only take up the subject of 

 migration in the business-like manner in which it is being investigated 

 by our Ornithologists, many unexpected results would follow, and 

 much that is now mysterious would be solved. — Eds.]. 



XYLOPHASIA ZOLLIKOFERI AT MIDDLESBEOUaH, YORKS. 

 BY T. ASHTON LOFTHOUSE, F.E.S. 



Being from home on the afternoon of September 26th last, and 

 it being fine and mild, I left instructions for " sugar " to be placed on 

 a few posts and stems of trees in the garden at Linthorpe, Middles- 

 brough. "When I arrived home in the evening I examined the sugar, 

 and took a Noctua off which I could not make out from anything in 

 my collection, or from any of the books at my disposal. After 

 taking it off the setting board I sent it to my friend Mr. G. T. 

 Porritt, who, after examining it and comparing with insects in his 

 collection, was unable to determine it, but he suggested it might 

 be Xylopliasia ZolUkoferi, and advised me to send it to Mr. Barrett 

 for determination, and on doing so, Mr. Barrett kindly examined it, 

 and he being uncertain as to its identity, took it to the South Ken- 

 sington Museum and, in company with Sir Geo. Hampson, compared 

 it with continental specimens in that collection, the result being that 

 they pronounced it to be Xylopliasia ZolUkoferi, a species of which 

 Mr. Barrett says " there is one certain previous British specimen in
