species, ? S. plistonicus, Plot/, (it is not S. motozi, Wallengr.), 

 in some numbers under the verandah at Kirokwe. This house 

 has a thatched roof and the verandah is very dark. I have 

 also seen the dry form of Precis sesamus, Trim., resting there. 

 At the same time I have found this last species quite freely 

 at flowers at all times of the day, even the hottest hours. 



" I fancy the habit of resting on rocks, and by no means 

 exclusively dark rocks, is even more universal in Sarangesa 

 at all seasons. 1 have little doubt that there are nocturnal 

 Hesperidae, e.g. Comities cylinda, Hew., and more particu- 

 larly Ploetzia cerymicd, Hew., which only appear at the same 

 time as the Hawk-moths come to light (see my note in Ent. 

 Mon. Mag., June 1913, p. 130). All the species of Rhopalo- 

 campta fly at least up till dark, though they are also on the 

 wing by day. I am inclined to the opinion that all this 

 group are more truly nocturnal than Sarangesa, though I 

 should agree that this last has to some extent adopted 

 nocturnal habits in extended dry seasons. 



" It looks as if the rains were near, but we have had 

 nothing more than quite light showers here yet, not enough to 

 make any difference. I have been up to Kiboriani this week 

 and saw several much-worn dry-season forms of Precis sesamus, 

 and P. antilope, Feisth., and one or two P. artaxia, Hew., but 

 have not seen a single wet form of this genus yet." 



Prof. Poulton said that a similar observation on P. cerymica 

 had also been made by Capt. G. D. H. Carpenter, who had 

 captured the insect coming to light at 9 p.m., although there 

 was evidence that the species was by no means exclusively 

 nocturnal or even crepuscular (Proc. Ent. Soc. Loud., 1915, 

 pp. xliv, xlv). 



The conspicuous Catocaline moth Egybolis vaillan- 

 tina, stoll, seized and dropped by a bird, at durban. 

 Prof. Poulton said that Mr. C. N. Barker had sent to him 

 the following observation recorded by Mr. Harold Millar, 

 who had written, Nov. 27, 1917, from the Zoological Gardens, 

 Mitchell Park, Durban : 



" I was in scrub bush yesterday, sitting quietly watching 

 a 'Noisy Bush-Chat' [Cossypha bicolor, Sparrm.], when 

 ( another of same kind came along, perched itself about 12 in.
