Mr. Hubert W. Simmonds contributed some " Notes on 

 an Unusual Emergence of ChrysopJianus scdustius in New 

 Zealand," as follows : — 



" A few notes on the very unusual appearance of our New 

 Zealand Chrysojohanus salustius this winter may be of interest 

 to Fellows of the Entomological Society. This butterfly 

 generally appears about the beginning of November, the 

 males first and the females becoming common a few weeks 

 later. There seem to be a series of emergences throughout 

 the summer, for fresh specimens are frequently taken up to the 

 end of March, and it lingers on well into April on the sea-coast 

 and other favoured spots. I was therefore very much surprised 

 to find a perfect ne.vly emerged 9 ^^ rest on a blade of grass 

 under the cliff at Titahi Bay early in July, and still more so 

 when on the 29th of that month (which was after a bright 

 sunny week but with cold nights) I again visited that locality 

 and found C. salitstius almost common flying in bright sunshine. 

 Nearly all the specimens were in perfect condition, and of the 

 four I caught (I had no net with me) all were $ s and two 

 more of the variety having the blue hind-marginal spots well 

 developed. Several others that I got close to were $ s and I 

 did not observe a single ^ . The locality was at the base of 

 some sloping cliffs sheltered from the south winds and getting 

 the sun all day. I have nob since visited this spot, and 

 although I have been in several similar localities in the 

 neighbourhood, I have not seen a single specimen. 



" The variety of the $ having the blue spots in the black 

 hind-marginal spots seems peculiar to the sea-coast, for all 

 that I have taken of this variety have been on the sandy 

 cliffs that form the coast-line in this district." 



Professor E. B. Poulton, F.R.S., communicated some 

 "further notes on the choice of a resting site by Pieris 

 rapse," by Mr. A. H. Hamm, as follows : — 



"On July 10th this year I observed a male of this species 

 at rest on the under-side of a dahlia leaf in my garden, 22 

 Southfield Road, Oxford. In no case had the dahlias bloomed
