402 L. de Niceville & Dr. L. Martin — Butterflies of Sumatra. [No. 3, 
so named, bnt not described, in Dr. O. Staudinger’s sale list No. xxxiii 
(1889). Wallace as viola. Wallace described T. viola from Singapore 
and Sumatra, but pointed out that the male lie described from Sumatra 
differed somewhat from his specimen from Singapore. The latter 
equals T. teuthras, Hewitson, teste Distant, the former T. atlita. 
135. Terinos Clarissa, Boisduval. 
Snellen as larissa [sic], Boisduval. 
136. Terinos teos, de Niceville. 
T. teos, de Niceville, Jonrn. Bomb. Nat. Hist. Soc., vol. viii, p. 41, n. 4, pi. K, 
figs. 5, male ; 6, female (1893). 
Grose Smith as robertsia. Snellen as robertsii [sic]. Hagen as robert¬ 
sia, var. ? sumatrana, so named, but not described, in Dr. 0. Staudinger’s 
sale list No. xxxiii (1889) as var. sumatre?isis. Wallace as robertsia , local 
form A. This species is a local race of T. robertsia , Butler, from the Malay 
Peninsula. Without knowing the habits of the species of the genus 
Terinos, one would know from their rich violet-blue coloration that one 
has to deal with true inhabitants of large forests, which never go to 
small jungle as the foregoing Gethosice often do. T. clarissa, Boisduval, 
is very rare, and no exact locality for it can be given except one 
specimen from Bekantschan, as all the specimens procured were brought 
in with numerous specimens of T. teos, de Niceville, Dr. Martin not 
noticing the difference between these two species till I pointed it out 
to him. T . atlita, Fabricius, occurs more in the plains, but not at a 
lower elevation than Bindjei and Selesseh, but does not extend higher 
than Namoe Oekor. T. teos, de Niceville, commences to appear at the 
same places and is found as high as Bekantschan and the lower hills. 
The butterflies are very restless, and fly round certain trees, on which 
they rest for a moment and then fly off again, so are not easy to 
catch, besides which they usually settle high up and fly high too. In 
November and December both the common species appear in large num¬ 
bers, while in all the other months they are only procured singly, and are 
very worn, so Dr. Martin thinks that they may be only single brooded. 
At Namoe Oekor in October Dr. Martin and I caught only worn females, 
males being entirely absent, and in December of the same year the 
collectors brought in many males and a few fresh females from the same 
spot. Otherwise females are always rarer than the males, especially 
that sex of T. atlita . The female of T. clarissa is unknown to us from 
Sumatra. No Sumatran species of the genus shew the beautiful whitish- 
violet patch on the upperside of the hindwing found in T. teuthras , 
Hewitson, and T. robertsia , Butler, from the Malay Peninsula.
