their possible function, whilst Scudder had described some 

 glandular structures which might produce the scent, but there 

 did not seem much in either case which amounted to a proof. 

 A resume of the matter was given in a paper entitled 

 " Secondary Sexual Characters in Lepidoptera," by J. W. 

 Tutt, F.E.S. The subject was highly interesting and he 

 should like to hear more from any entomologist who might 

 have studied it. 



Mr. Tngpen suggested that as the attractive scent seemed 

 only to last a short time, might it not be due to something 

 analogous to the pith found in the feathers of birds, which 

 after a time became dried up. 



Mr. Karop said there could be no possible homology between 

 the structure of a bird's feather and that of an insect's scale. 



The Chairman said the subject of insects' scales was a very 

 elaborate question and too wide for them to go into on that 

 occasion ; indeed, he thought it was one which had been so well 

 thrashed out that they would be likely to get very little to add 

 to what was already known. 



Mr. J. D. Hardy described a form of Melicerta found in his 

 aquarium, the peculiarities of which he illustrated upon the 

 board. He would be glad to hear from any of the members 

 present if the species was new, as in that case he would try to 

 find some more of the same kind. 



Mr. Rousselet had not seen anything similar to it, and should, 

 therefore, be very glad to have a specimen for examination. 



Mr. Neville said it was a common thing for Melicerta to have 

 the lobes presented in the horizontal position described, and the 

 condition of the tube was often due to the surroundings. As 

 this specimen was found in an aquarium, it was possible that 

 the difference observed in the pellets might in some way be due 

 to a deficiency of ordinary material in the water. 



Mr. Hardy said this was clearly not so in the present case, as 

 he had a quantity of Melicerta in the aquarium of the common 

 kind which were building their tubes quite in the ordinary way 



The thanks of the Club were voted to Mr. Ingpen and to Mr 

 Hardy for their communications. 



Announcement of meetings for the ensuing month were made 

 by the Secretary, and the proceedings terminated with the 

 usual conversazione.
