which I should not be glad of, even to Pieris oleracea, Grapta fait mis, and 

 Danais chrysippus. Thus even the commonest species would be very 

 acceptable. My plan is to send a large box from Liverpool once a year, 

 instead of smaller ones, though I occasionally forward lesser ones by 

 post. Address : — Dr. Jordan, 35 Harborne Road, Edgbaston, Birming- 

 ham, England. [We take this opportunity of thanking Dr. Jordan for 

 the little box, containing 46 species of beautiful English Lepidoptera, that 

 he so kindly sent us. They came by post, and, thanks to careful packing, 

 arrived in excellent order. As soon as we obtain a little leisure we shall 

 return the box — not empty. — Ed. C. E.] 



Pieris rap,*;. — This destructive pest of the cabbage and allied plants 

 has now come as far west as Port Hope ; it is almost as abundant in our 

 garden as the common Colias philodice. No doubt it will proceed as far 

 as Toronto before the close of the season. We have not yet perceived 

 any particular depredation from its larvae in the kitchen garden, but we 

 fear that we shall not long enjoy this immunity. — C. J. S. B. 



Sembling. — On the 19th of June last a fine female Cecropia Emperor 

 moth issued from its cocoon, which had been cut from an apple tree and 

 kept in my study for some weeks. Being anxious to try the virtues of the 

 process of ••'sembling,'' I fastened its wings by an ordinary spring clip 

 and exposed it on my verandah for several nights without success ; the 

 evenings were fine and cool. On the 28th, the evening being warm and 

 misty after a shower, the moth was exposed as usual on an empty flower- 

 stand, just outside of an open window ; inside the room on a table a lamp 

 was kept burning. About 1 1 o'clock, p. m. , I entered the room and 

 observed nothing but a few ordinary Noctuae flying about ; on returning, 

 however, an hour later, I was amazed to find four splendid specimens of 

 the male Cecropia quietly at rest upon the table and lamp ; a few 

 moments after a fifth came in and flew wildly about the room, succeeded 

 in a little while by a sixth ! They were all in excellent order and 

 evidently fresh from their cocoons. As I had kept the female so long in 

 confinement, I determined not to continue the experiment any longer ; I 

 accordingly dispatched five of the males with chloroform, while the sixth 

 was left with the object of his attraction. The result was a large batch 

 of eggs and subsequent larvae. As the female was entirely hidden from 

 view underneath the window, and was not found by the males, who entered 

 the room to the light instead, flying but a short distance over the fair one 

 of whom they were in search, it is evident that they were guided to the
