Auriv., Avhilst the male of this Lycaenid accurately resembled 

 a male Planema allied to that which formed the model of the 

 female alciope. All the species involved were exhibited, the 

 female Lycaenid being represented by an imitation specimen 

 made of paper and copied from Aurivillius's figure, there being 

 no example of the female in this country. The mimetic 

 relations might be illustrated diagrammatically in the follow- 

 ing manner, the arrows expressing the connection of model 

 and mimic, and pointing from the latter to the former.

One result of the investigation was that the alicia of Smith 

 and Kirby could no longer stand, firstly because it was an 

 Acraea and not a Planema, secondly because the name was 

 preoccupied, thirdly because the alleged male was a female, 

 and fourthly because the female was the same as aurivillii, 

 and aurivillii was alciope. The latter might be retained as a 

 varietal name for the East African female.

Mr. Eltringham said he would like to express his sincere 

 thanks to Dr. Jordan, to whom to a great extent the result 

 of the investigation was due. 



Probable Mimetic association of Aculeate Hymenoptera. 

 — The Eev. F. D. Morice brought for exhibition a number 

 of specimens of Aculente Hymenoptera which he suggested 

 formed probably a Mlillerian group. Though belonging to 

 several widely separated genera they were on the whole very 

 similarly coloured (most of them e. y. having yellowish-hyaline 

 wings with black tips). All were taken on a single occasion 

 visiting the small yellow flowers of one particular tree in the 

 alluvion of the Wady Kelt, near Jericho. Another specimen
