( “hxc” ) 
altogether absent in 1913. I think I know the food-plant, 
which seemed to be growing as strongly as ever. 
10. Teracolus eris, Klug. In 1912 I took one im very poor 
condition in a garden near our house and quite away from the 
desert. The next specimen I saw was in my breeding-cage, 
where it emerged from the chrysalis of a small green larva 
which I had unwittingly brought home on the food-plant of 
B. mesentina. I found four more larvae, and two eggs which 
hatched, and the caterpillars from them were almost full grown 
when ants got into the cage and devoured them and other 
treasures. The egg was clear except for an irregular red line 
running round it: it was laid on the upper side of the leaf. 
The caterpillar was green, wood-louse shaped, and hard to 
see, as it generally lay along the midrib of the leaf. 
11. Teracolus ewpompe, Klug. In 1912 this very lovely 
insect was quite common, but in 1913 I took only a couple 
of males, though I was constantly on the look out for it. It 
is a species that varies verv much as to size, and the female 
has a great tendency to vary in the amount of red at the tips 
of the wings; often this is quite absent, but the underside 
appears to be always characteristic. 
12. Teracolus achine, Cram., is never abundant, but in the 
course of an afternoon’s hunt two or three specimens will 
come to hand. I have taken it more commonly at Suakin 
than at Port Sudan. 
13. Teracolus daira, Klug. This inconspicuous little butter- 
fly, so far as I know, is only taken in one spot on the bank of 
a “khor” near Port Sudan, where it sits in the rough grass, 
seldom apparently flying much. 
14. Teracolus liagore, Klug, is another butterfly favouring 
tufts of grass near “ khors.”’ It is a rare insect, and one pair 
in an afternoon is the largest number I have taken at a time. 
15. Teracolus evarne, Klug, is the common butterfly of the 
place. Every winter I have found it abundantly. From a 
long series one may pick out small and pale examples known as 
philippsi, Butl. I have tried to breed this species from eggs 
laid in captivity, but the infant larvae refused to eat. The 
egg was straw-coloured at first, then vermilion, and hatched 
on the fourth day.
