edgworthii. The larva is a fat reddish one, but I did not make 

 any careful notes regarding it. 



" lOLAUS NUBSBI. 



This Butterfly was not eomiiion, and I never saw it except at 

 Shaik Othman, where the few specimens I got were taken. 



" lOLAtJS 6LATJCUS. 



These were the only specimens I took. 



" TerIAS OHAtCOMl^ETA. 



Common at Lahej. 



"Tbbacolus CALAIS, var. dynimbne. 



I suppose all these are T. dynamene. I .found the larvce on 

 Salvaddra persica, and I also bred ^isome 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 larvro have two 

 black spots dotted with white behind the head, and on some the 

 first half of the streak down the back is wliitish, others have it 

 whitish the whole length. Some of the larvfB have black heads, 

 others green beads. 



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 'SO on the leaves of the 

 food-plant, and the larvse remain gregarious for at least half the 

 larval stage. T'hey remind one of Sawfly larvie. I bred larvoe of 

 all the colours mentioned above from the same batch of eggs. 



" TEEACOLrs phisadia. (Plate X. fig. 13.) 



Common at Aden and in the interior. I found the larvse 

 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. 



" Tbracoltjs VI. 



I did not get many specimens of this species and I could not 

 succeed in Hnding the larva, though I. searched carefully many 

 times. 



" Teracolus plbione (and T. miriam). (Plate X. fig. 18.) ' 



Very common at Aden, but, like Col. Yerbury, I never saw it 



elsewhere. I found plenty of the larvae feeding on Cadaba
