edgworthii. The larva is a fat reddish one, but I did not make 
any careful notes regarding it. 
_ “ TouAUS NURSEI. 
This Butterfly was not common, and I never saw it except at 
Shaik Othman, where the few specimens I got were taken. 
** TOLAUS GLAUCUS. 
These were the only specimens I took. 
6¢ THRIAS CHALCOMIETA. 
Common at Lahej. 
«‘TRRACOLUS CALAIS, var. DYNAMENE, 
I suppose all these are 7. dynamene. I found the larve on 
Salvadora persica, and I also bred some from the egg. The 
following is a description of the larva :— 
Pea-green, very slightly rough: lower part lighter green; a 
slightly darker mark along back. Some of the larve have two 
black spots dotted with white behind the head, and on some the 
first half of the streak down the back is whitish, others have it 
whitish the whole length. Some of the larve have black heads, 
others green heads. 
The pupa also is very variable. Some are very pale green, 
others yellowish brown dotted with black. 
The eggs are laid in batches of 20 or 30 on the leaves of the 
food-plant, and the larve remain gregarious for at least half the 
larval stage. They remind one of Sawfly larve. I bred larvee of 
all the colours mentioned above from the same batch of eggs. 
“‘TpRACOLUS PHISADIA. (Plate X. fig. 13.) 
Common at Aden and in the interior. I found the larve 
feeding on Salvadora persica. The following is a description of 
it :— 
Pea-green ; when young, two black spots on back of head; a 
white mark, almost the shape of an ace of diamonds, but rather 
longer, on second segment; when older the black spots on head 
disappear, and the white mark gets clearer and is outlined with 
black. ‘There are two similar marks just beyond the centre of the 
back, the front being the smaller, and another similar mark on 
eleventh segment. 
‘“‘ THRACOLUS VI. 
I did not get many specimens of this species and I could not 
succeed in finding the larva, though I. searched carefully many 
times. 
«¢ TERACOLUS PLEIONE (and T. MirtAM). (Plate X. fig. 18.) 
Very common at Aden, but, like Col. Yerbury, I never saw it 
elsewhere. I found plenty of the larve’ feeding on Cadaba
