(Cassia) which is not a native. It is usually scarce in 
the hill districts, but common lower down, and would be 
extremely abundant if it were not for the tremendous 
destruction of eggs and larve. I doubt whether one egg 
in five hundred ever comes to maturity. I have noticed 
a plant fairly covered with eggs and two days afterwards 
they were comparatively scarce. Ants carry them off by 
hundreds, and the young larve are eaten by a small green 
spider. The larve in the last stadium vary considerably. 
In many, perhaps the majority, the lateral white line is 
tinged with orange and the black lateral line is continued 
as a black collar behind the head; the last two or three 
segments are also more or less crossed by extensions of 
the black lateral lines. I may say that the sex of the 
perfect insect is in no way indicated by the different 
markings of the Jarva. There are two broods in the hot 
weather, at the beginning of December, and another in 
February and March; the pupe from the majority of this 
brood remain over the cold weather and emerge the 
following December. 
Bourson. I did not meet with this insect, and Vinson 
says it is rare.

Mauritius. Scarce above 1,000 feet; common and fre- 
quently abundant below this level, and widely distributed. 
The dry-weather form, Z'erias ceres, Butl., occurs sparingly, 
but so far as I have observed, in the low country only. 
Flies all the year round except in the coldest month, July. 
The same remarks apply to the species in Bourbon.

If it were not for the opinion expressed by Trimen 
(“S. Afr. Butt.,” 3, p. 18, note 1 [1889]), that this is dis- 
tinct from Zerias brigitta, I should certainly consider it to 
be the same species, as I have specimens from Mauritius 
which are indistinguishable from 7. brigitta, or rather 
T. zoé, from Natal. , 
It can, I think, be considered as at most a geographical 
race of that species. The wet-season form (7. zoé) is far 
more frequently met with than the dry (7. brigitta), and
