Sept. 28, 1915.—The Euphaedras were found as larvae 
in a company on their host-plant. They were a curious 
chocolate-brown colour with processes like those of 
Hamanumida or Aterica of a vivid sulphur-yellow colour, 
which gave them rather a fearsome look. 
5. Harma (Cymothoe) theobene Dbl—Hew.—{The material, 
bred in 1915, includes 3 ¢ emerging Aug. 1, 9, 11; 2 
nigrolutescens Q forms (p. 469)—Aug. 4, 21; 2 theobene &. 
forms—Aug. 10, 11. The g and 9 of Aug. 1 and 4 pupated 
July 22 and 26, respectively. All except the 2 of Aug. 
21 have precise pupa-cases. For an account of the 9° 
polymorphism of this species and Lamborn’s families from 
known female parents see pp. 469-72. ] 
Sept. 28, 1915.—I am most interested in what I think 
must be a Cymothoe. The caterpillars were all found on the 
same host-plant in the bush, and were all identical. There 
would appear to be three imaginal forms. 
6. Neptis nemetes Hew.—{Two specimens with precise 
pupa-cases were sent, bred from larvae found on the same 
plant in the bush :—1 9, emerging 1.0 p.m., Aug. 11, 1915; 
1 g—Aug. 12. The 2 pupated Aug. 1.] 
7. Acraea lycoa Godt. and A. pentapolis Ward.—{ A bred 
series of lycoa, 2 $ 4 9, emerging Aug. 22, 1915; 2 5— 
Aug. 24 and 25, these two latter with precise pupa-cases. 
One  pentapolis, emerging Oct. 2, 1917, from a pupa found 
at Agege. | 
B. Tue UNDER SURFACE OF THE NYMPHALINE BUTTERFLY 
CRENIS AMULIA CR. 
[The following letter was written from Kew. Two 
specimens are labelled “ Aro-Chuku 13.v.14,” the third, 
undated, “E. Prov. of S. Nigeria. Bonny, Aba, Aro- 
Chuku, Azumini. Butterfly showing H amanumida-like 
variation.” The resemblance to a common form of the 
variable under-surface of Hamanumida daedalus F. is 
certainly strong, and it is probable that Farquharson was 
suggesting mimicry of the abundant by the rarer species. 
It must, however, be remembered that daedalus could only 
act as a model during the daylight hours of complete rest. 
In the intervals of the active state it invariably rests with 
expanded wings, as Farquharson well knew (Proc. Ent. Soc., 
1914, p. xxxix).] 
Oct. 26, 1914.—I am sending three butterflies—not in 
good condition, I regret to say, and to be effective I ought
