size : — " Towards the end of June 1910, I saw a small robin 

 flying with what was evidently a heavy load across the path 

 of the Parks Road, Oxford, from the elm-trees on the west 

 towards the Parks railing on the east. Just outside the 

 railing it put the load down and began to peck it. I came 

 near gently, and saw that it had captured a specimen of 

 Smerinthus tiliae, L. I watched the bird peck the moth to 

 pieces and eat the whole of it, except the wings. The observa- 

 tion was made just after heavy rain, which may have caused 

 the moth to flutter or fall, and thus to attract the bird's 

 attention." 



Mr. S. A. Neave said with refei'ence to Professor Poulton's 

 interesting remarks on the prevalence of insectivorous birds in 

 Uganda, that he had recently had an instructive experience 

 near Entebbe. On January 12, 1912, at Gabunga's, near 

 Entebbe, he had watched a wagtail, most probably Motacilla 

 cajjensis, catching butterflies on a small patch of damp sand 

 in the bed of a forest stream. The bird was so tame that 

 he stood within 3 or 4 yards of it. In less than half-an-hour 

 this bird captured and ate 19 butterflies and failed to catch 

 many others. The butterflies eaten were nearly all small 

 Lycaenklae, including Tcvrucv^ tellcaniis, Pohjommatus baeticus, 

 Azanus spp., many individuals, Lycaenesthes spp. (2 indi- 

 viduals), Uranothauma (1) j)oggei (1 individual), and a single 

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

 rejected after tasting, a specimen of Acraea 2}elasgius. 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. 



Neptis and ISTeptidgpsis 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
