Terias lacteola, Distant, Rhop. Malay, p. 466. n. 8, fig. 129 (1886). 

 Common in some places. 



151. Terias ada, n. sp. 



Allied to T. lacteola^ Dist., but differing in the following 

 particulars : — The ground-colour is pale sulphureous and not 

 whitish, the black marginal borders to each wing are also 

 wider and blacker ; the wings beneath are pale sulphureous, 

 and the markings are similar to those of T. lacteola^ but more 

 obsolete and somewhat obliterated. 



Exp. wings 35 millim. 



This is a well marked species of Terias, the wide black 

 margin to the posterior wings rendering it very distinct. It 

 has been compared with the large collection of Teriads in tlie 

 British Museum and also with the rich collection of species in 

 the collection of Mr. F. Moore.
