Terias, probably T. senegalensis. The bird also seized, but 

 rejected after tasting, a specimen of Acraea pelasgixus. This 

 individual, with one hind wing torn off, was subsequently pro- 

 cured. Except for the loss of the wing it appeared to be 

 uninjured. 



Mr. G. A. K. Marshall and Dr. G. B. Longstaff also 

 spoke on the subject, the latter giving an account of a 

 struggle he had witnessed between a bird and a large grass- 

 hopper, in which the latter was eventually successful. 



Nbptis and Nbptidopsis in the Lagos District. — Refer- 

 ring to his recent communication (in these Proceedings 1912, 

 p. xxvi) on the proportion of the species belonging to these two 

 genera in the neighbourhood of Entebbe, Professor Poulton 

 called attention to a statement received in a letter from Mr. 

 W. A. Lamborn, dated March 22, 1912 : — " Neptidopsis would 

 lvi] 



I am sure outnumber all the species of Neptis put together 

 at any season. I have not taken any more because I thought 

 I had probably sent enough." 



Eurytela Hiarbas and E. Dryope. — Professor Poulton 

 said that his friend Mr. Roland Trimen, F.R.S., had pointed 

 out to him that Mr. Lamborn's results published in these 

 Proceedings (1912, p. xviii) are "confirmatory of Miss Foun- 

 taine's experience in Natal, given in Trans. Ent. Soc. Lond., 

 1911, p. 59. She records that although she had bred both 

 forms indiscriminately from every variety of the larva, she 

 nevertheless found that ' the ova laid by E. hiai-bas always 

 produced hiarbas, whereas those of a dryope ? invariably 

 produced dryope. 1 " 



Paper. 

 The following Paper was read : — 



" On the Colour-Groups of the Hawaiian Wasps," by Dr. 

 R. C. L. Perkins, M.A., D.Sc, F.Z.S., F.E.S. 



Prof. Poulton, in introducing the paper, said that Dr. 

 R. C. L. Perkins had illuminated a problem of the most 

 fundamental interest and importance for the student of 

 evolution. His work was of equal interest to the follower 

 of systematics and of bionomics.
