order to show that the apparent thickening of the median 

 nervules and submedian nervure, in that sex of the species, 

 was due to the dense covering of broad scales, bent over and 

 concealing some very narrow clavate black scales, or andro- 

 conia; these appeared to be of a different substance to the 

 ordinary scales of the wings, so that when, by the Water- 

 house process, he had denuded the wings of the ordinary 

 scales the androconia remained intact, and were removed by 

 the use of the camel's hair brush, considerable friction being 

 necessary. Mr. Jenner Weir remarked that he had been in- 

 duced to bring this matter before the Society, because he 

 found that some British Entomologists appeared to think 

 that in the restricted genus Argynnis there was a real dilata- 

 tion of some of the median nervules, and occasionally of the 

 submedian nervure, but a reference to Mr. Scudder's work on 

 the " Butterflies of the Eastern United States and Canada," 

 and to the " Exotische Schmetterlinge von Dr. Staudinger 

 und Dr. Schatz," would show that neither the American nor 

 German Entomologists named had fallen into such an 

 error. 



Mr. Croker exhibited dark forms of GnopJios obscuraria, 

 Hb., from the New Forest, and a specimen of TcBniocampa 

 gothica, L., closely approaching ^2S. gothicina, H.-S., taken at 

 West Wickham Wood. Mr. C. Fenn mentioned having 

 taken a similar variety at Lewisham. 



Mr. Turner exhibited a pinkish variety of Hypsipetes sordi- 

 data, Fb., also dark forms of Boarmia geimnaj'ia, Brahm., 

 from Ashdown Forest, and specimens of Cabera rotundaria, 

 Haw. 



Considerable discussion took place as to whether the last- 

 named was a distinct species or a variety of Cabera pusaria, 

 L., in the course of which Mr. R. Adkin referred to an exhibit 

 by Mr. Atmore at the Society's Exhibition in 1888 of a long 

 series of C. pus aria, in which were two specimens having the 

 primaries on one side of the body approaching C. rotundaria, 

 and on the other ty^'xcd^ piisaria ; these were bred from larvae 

 taken in i!
