EXPLANATION OF PLATE XXVI. 
Lycaenesthes lachares, Hew., both captured and bred in the Lagos 
district. 
All the figures are slightly below the natural size. 
Fies. 1-10. Females taken (1910-11) in the neighbourhood of Oni; 
all except the specimen represented in fig. 3, differ 
from the normal form of this sex in the absence or 
very slight development of the yellow patch in the 
centre of each wing (see pp. 478-9). 
1 & 2. Mar. 26, 1910. Flitting together in a dry swamp } mile 
N. of Oni. 
3. Apr. 5, 1910. In the forest within 3 miles of Oni. The 
yellow patches strongly developed especially in the 
fore-wings. 
4. May 24, 1910. On a path, Oni Clearing. 
5-10. Jan. 1, 1911. All taken at the same spot in the forest 
1} miles E. of Oni: evidently freshly emerged from the 
pupa. 
11-30. Females bred from larvae taken in the neighbourhood of 
Oni. The figures are arranged to show an increasing 
development of the yellow patches from left to right. 
The majority of the bred specimens are shown to con- 
trast strongly with all of the captured ones except fig. 3, 
and are as a matter of fact the normal form of the 
species. It is probable that something in the arti- 
ficial conditions has acted as a shock and caused 
reversion to the normal type. It will be noted that 
the development of yellow patches runs with re- 
markable constancy in each of the little families bred 
from larvae found together. 
“No. 615,” and each of the following numbers 
denotes a separate family.
