the exhibit was arranged so as to show the parallelism exist- 
ing between many species of these genera, a parallelism which 
it could hardly be doubted was in most, if not in all cases, of 
mimetic significance. The genera included in the exhibit 
were Mylothris, Phrissura, Pinacopteryx, Belenois and Leucer- 
onia. The members of the same genus were arranged in 
vertical rows, while the species of different genera showing a 
similar appearance were set out side by side, horizontally. 
The various assemblages, each presenting a distinct pattern, 
with their constituent species, were as follows :— 
I. White with dark marginal spots. Mylothris agathina, 
Cram., 6; Pinacopteryx rubrobasalis, Lanz., 3; Belenois thysa, 
Hopff. ¢; Leuceronia argia, Fabr., 2. 
II. Brownish-yellow with dark marginal spots. MV. agathina, 
9; Pinacopteryx vidua, Butl.,2; B. thysa,? (dry season). 
Some specimens of Pinacopteryx astarte, Butl., 9; of Belenots 
theora, Doubl., 2 ; and alsoa form of L. argia, 2, belong to this 
group, but were not shown. 
III. White with dark apical patch and dark marginal 
spots. Phrissura phaola, Doubl.,¢; Pinacopteryx dixey?, 
Neave, 6; Belenois theuszi, Dewitz, 6; L. argia, ¢. 
IV. The same, with a slight brownish-yellow basal suffusion. 
M. poppea, Cram., 6; P. dixeyi, 2; Belenois :anthe, Doubl., 2 ; 
Leuceronia thalassina, Boisd., 2. 
V. White; marginal dark spots tending to become streaks ; 
an orange or pinkish basal flush. J/. poppea,? ; Phrissura 
isokant, Gr. Smith, 9 (= P. phebe, Butl.); B. ianthe, Q; 
Belenois sp. (allied to B. thysa), 9; L. argia, 2. 
VI. Fore-wings brownish-yellow with dark margins ; hind- 
wings white or creamy with dark marginal spots. J/ylothris 
spica, Mésch., 2; Phrissura sylvia, Fabr., 2? ; L. thalassina, ¢ .

Specimens of B. theuszi,?; of B. theora, Doubl.,?; and of 
L. argia, 2( form semiflava, Auriv.) also come into this group, 
but were not included in the exhibit. 
VII. Bright yellow with dark marginal spots or (on fore- 
wings) an irregular marginal band ; fore-wings with orange 
basal flush. Mylothris riippellii, Koch, ¢ (yellow form) ; Z. 
argia, 2 (form sulphurea, Auriv.).
