expected, from butterflies being dried for the cabinet, though 

 I have found it still strong in a specimen of G. napi, ^ , that 

 had been eleven days in a cyanide bottle. 



" I have here specimens of some of the common Pierine 

 odours preserved in both ways — G. brassicfe, G. rapie and G. 

 napi in rectified spirit, G. o-apx and G. napi in starch powder. 

 There are also, in similar bottles to the scents, samples of the 

 spirit and starch used, in order to help in distinguishing any 

 odour attaching to these substances from that due to the 

 butterfly scales. I produce these specimens with some hesita- 

 tion, because I am well aware that the perfumes are faint, and 

 indeed are probibly quite imperceptible to many people. That 

 the bottles still retain sufiicient odour to be easily discriminated 

 by some persons, at any rate, I had proof this morning before 

 bringing them here, and also this evening since entering the 

 room." 



Prof. R. Meldola, F.R.S., mentioned that he had already 

 detected the scent of Zanclognatha tarsipennalis. The Rev. F. 

 D. MoRiCE said the scent of some species of Hymenoptera 

 was characteristic and well known. Mr. J. E. Colltn said 

 that some Diptera emitted a musky scent, and Col. Bingham 

 instanced the case of certain Eastern Euploeinx. Mr. J. W. 

 TuTT, Mr. M. Jacoby, the President and other Fellows joined 

 in the discussion. 



Mr. H. J. Turner exhibited examples of the larva of 

 Phorodesma smaragdaria, which he had met with in some 

 numbers on the Espex marshes while searching for Coleo- 

 phorid larvpe. The protective resemblance attained by the 

 attachment of numei'ous small portions of the food, Artetnisia 

 tnaritima, was well exhibited in a photograph sent to him by 

 Mr. Edwards of Worcester, of several larvae at rest on sprays 

 of that plant. He stated that most of those he had met with 

 were in situations which would necessitate their being under 

 water at each high tide. 



Mr. Turner also exhibited a further contingent of the 

 living larvae and cases of the Lepidopterous genus Coleophora, 

 and contributed the following notes : — 



" C. therinella. — A number of larvpe of this local species 

 were very kindly sent me by Mr, Eustace Bankes from
