as in melicerta, divided at its distal extremity. There could 

 be no reasonable doubt that metella was a mimic. To one 

 unfamiliar Avith the species, it was a great surprise to see 

 the under surface for the first time, and then to realise that 

 the pattern of the upper side had given an entirely false 

 impression of affinity. The three remaining species, nico- 

 medes, nysiades ab. continuata, and puella, were closely similar, 

 and would be indistinguishable upon the wing. The two 

 Hypsid moths presented a rough approximation to the pattern 

 of agatha. 



Neptis Swynnertoni, a new species from S.E. Rhodesia. 

 — Professor Poulton exhibited the male and female types, 

 described below by Mr. Roland Trimen, F.R.S., together with 

 a specimen captured in the garden at Chirinda (3,800 ft.) 

 on March 28, 1911, by Mr. C. F. M. Swynnerton. The 

 "paper" bore the note "continually settling on the ground. — 

 C. F. M. S." Two specimens of the closely allied N~. incongrua, 

 Butler, captured by Rev. K. St. Aubyn Rogers on Feb. 16, 

 1911, at Chawia, British East Africa (5,000 ft.), were also 

 exhibited, so that they might be compared with the new 

 form from the south. The far narrower bar of the hind wing 

 of incongrua, together with the much smaller size of the 

 principal fore wing marking, at once served to distinguish 

 the two forms.

 size — the first (minute subcostal) spot is wanting, the second 

 is smaller and narrower, but the third larger and rounder 

 than in incongrua, ; the fourth and fifth are very much

 This species was originally described from Nyassaland (6 6) examples, 

 but has since been found in British East Africa, two examples in the 

 Hope Department having been taken by Rev. K. St. A. Rogers at Taita 

 and Tuso (Kikuyu Co.) respectively (see also above). — R. T.
