mimicry of one species of the Pieridinse by another species of the same 

 sub-family. 



Mr. Bates suggested that the resemblance between the Mylothris and 

 the Beleuois was only a relation of affinity. And the President also doubted 

 whether this was a case of mimicry. 



Mr, W. C. Boyd exhibited some varieties of several British Lepidoptera; 

 amongst them, a female Colias Edusa with the black spot on the front wings 

 almost obliterated, captured in the Isle of Wight in 1859 ; a dwarf Pieris 

 rapse, captured at Cheshunt ; a dwarf Liparis auriflua ; the dark form of 

 Miselia oxyacanthse ; a very pretty and curious Polia chi (?) ; and an 

 Agrotis aquiiina with the stigmata joined by a distinct brown line. 



Mr. Verrall exhibited a specimen of Plusia interrogationis, captured by 

 Mr. Jenner at Battle, Sussex — a new locality for the insect. 



Prof. Westwood called attention to the fact that in the continuation of 

 Sepp's Nederlandsche Insecten (Ser. 2, vol. ii. pi. xhi.), Dr. Snellen van 

 Vollenhoven had recently figured an Agrotis with a Dipterous parasite 

 of the genus Anthrax. Though familiar as a parasite on Coleoptera 

 and Hymenoptera, Anthrax had not hitherto been known to attack 

 Lepidoptera.
