THE YOUNG NATUKALIST. 



251 



Eup. Oursoni. — This species had special attention, the result being the cap- 

 ture of a most magnifient series of beautiful specimens, taken as they 

 emerged from the pupa, they are quite equal to bred ones. Some are 

 broad banded, some narrowly strigate, but all are bright silvery steel 

 greys. 



Eup. Nanata. — Tt is now conclusively shewn by the close observations of 

 Mr. Curzon and Mr. Salvage that no specimens of this species can be 

 found on the Isle of Unst, in fact Nanata does not occur so far north 

 as any of the Shetland Isles. 



Musculosa. — Bright silvery but small specimens. The hind large blotch often 

 reduced to a small dark patch. Yar. Splendance of my collection. 



Gelechia tetragonella. — N.S. taken May 20th, as per note-book, amongst 

 stunted heather. 



P. crucifera, — A perfect pest in 1884, not seen in 1886. 



Cosciata. — Abundant in 1884, only one specimen seen in 1886. 



Dalella. — Common in gardens, feeding on the underside of cabbage leaves, 

 eating round holes in the leaf, and laying along the ribs in its web. 

 The disputed Agrotis Cursoria Tritici, searched anxiously and persistently 



for where it occurred so freely in 1884, could not be found in 1886, either 



as larva or imago.

EXCHANGE. 



Exchange now-a-days is funny. Casting one's eye down the column of an 

 exchange list, we see many things that make us smile. We will see for in- 

 stance one gentleman who will sacrifice such insects as L. marginata, Testata, 

 Polyodon f Plecta, and Atalanta, and all he requires are a few Scoliceformis, 

 Expallidata, and Coronata. Another gentleman offers Orbona, Oleracea, 

 Brassicce, all bred, and Polyodon, and informs his intended correspondents 

 that his wants are numerous. Now, this generous collector must have wasted 

 his valuable time in setting a tremendous supply of these rarities or he finds 

 it difficult to dispose of insects that any incipient of half-a-years experience 

 can take in his own garden, be it only a window-box; whichever it may be he 

 thrusts his advertisement before the Entomological public no less than seven 

 or eight times in succession. Another misguided individual three oi four 

 times informs Entomoligists that he might be induced to part with V. urticce, 

 Io, Brumata, Didymata, Grosulariate, Lubricipeda, Menthastri, and Typica, 

 for his numerous wants. One gentleman goes as far as to offer P. brassicce. 

 Surely there ought to be some line drawn. It is an insult to the science to
