ticed in this connection consisted in the fact that the structure 

 of the mandibles after moulting was very different from that

 the Trans. Amer. Entom. Soc, Vol. v [see Rec, No. 324]. 



§ 19. Protrusile Abdominal Appendages of Moths. 

 Mr. B. p. Mann read extracts from a letter of Fritz Mliller 

 to Chas. Darwin, published in Nature, vol. x, No. 241, p. 102 

 (June 11, 1874), i-especting the presence and character of ab- 

 dominal appendages in several Glaucopid moths, similar to those 

 described by Mr. H. K. Morrison in Psyche, vol. i, p. 21-22, 

 as found in the male Leucarctia acraea. (Febr. 12, 1875.') 



Mr. H. K. Morrison showed a specimen of Chamyris 

 cerintha, which has an appendage, whose use is problematical, 

 at the base of the abdomen beneath. (^Api'il 9, 1S75.')
