their last moult. A friend of mine has also found two in his garden 

 at Tooting, S.W. — A. J. La.wrance ; 65, Malyon Road, Ladywell,

Larv^ in Durham. — This year has been one of the most successful 

 years for larvae I have had. We have taken within a very few miles 

 of Newcastle-on-Tyne about fifty larvffi of Tripha;na fimbria, one hundred 

 of Argijnnis euphrostjne, eighty of Eupithecia tcmdata, and one of A. 

 selene. These figures are rather remarkable, for the local records say 

 that A. cuphrosyne is disappearing from this district, and similarly with 

 A. selene. We obtained larvse of the two Argynnids mentioned in about 

 two hours, for we only sought one day. — J. W. Harrison ; 1, Craig

SOCIETIES. 



Entomological Society of London. — April IGth, 1902. — The Rev. 

 Canon Fowler, M.A., D. Sc, F.L.S., President, in the chair. — Mr. 

 James Roland Charnley, of Howick House, Howick, near Preston, 

 Lancashire ; and Mr. A. T. Gillanders, of Park Cottage, Alnwick, 

 were elected Fellows of the Society. — Mr. 0. E. Janson exhibited 

 specimens of both sexes of Ornithoptera victoria, from Ysabel, Solomon 

 Islands, recently taken by Mr. Albert Meek; and remarked on the 

 variation in the colour and markings iu the males.— Mr. H. W. 

 Shepheard-Walwyn exhibited variations of Euchelia jacobaa taken by 

 him at Winchester in July, 1889. — Mr. Willoughby Gardner exhibited 

 Ccelioxijs mandibularis, Nyl., from the Cheshire coast, a species new to 

 Britain ; and Osmia xanthomelana, male and female, and Osmia parie- 

 tina. Curt., male and female, from North Wales. — Mr. A. J. Chitty 

 exhibited a specimen of Aglais urticm taken at sallow on March 28th, 

 having a large portion of the hind wings cut off, so that when folded 

 they were symmetrical in outline. From their appearance he con- 

 cluded they had been bitten off by some animal, probably during 

 hybernation. — Dr. T. A. Chapman called attention to the remarkable 

 bilateral asymmetry in the male appendages of the Hemarid Sphinx, 

 Cephonodus hylas, Linn. He said that bilateral asymmetry in insects 

 was sufficiently rare to make it always notable. In the male apo- 

 physes of Lepidoptera he had only been able to find records iu the 

 case of the Hesperid genus Thanaos, to which Scudder and Burgess 

 first called attention — though it seems highly probable that the facts 

 can hardly have been unobserved in so common a species as C hylas. 

 In hylas the right clasp is larger, rounded, but very imperfectly articu- 

 lated to the base, so as to be capable of very little movement, other- 

 wise, and compared with other Hemarid genitalia, one would call this 

 the normal clasp. The left clasp looks at first as though it had been 

 the same as the right, but had met with some accident that had 

 removed a large terminal disc, leaving two lateral cusps. It is shorter 

 than the right as about three to five, and the arrangement of bristles 

 and spines is quite different to that on the right, if it is indeed possible 

 to compare these very different forms. It is much more movable 

 than the right clasp. The arrangement suggests that it is intended to
