This species differs from 7. clarissa, in the anterior wing, by 
having a larger portion of it covered with the plush-like scales. In 
T. clarissa they extend upwards very little beyond the lower discoidal 
nervure. In 7’. teuthras they go beyond the upper discoidal nervure. 
The two species are, however, so closely allied that I should have 
hesitated to describe this as a distinct species if I had not discovered 
that the third disco-cellular nervure meets the median nervure dif- 
ferently. In T. clarissa the lower disco-cellular meets the median at 
some distance before the base of its second branch ; in 7’. feuthras 
exactly at the base of the said branch. 
TERINOS TERPANDER, 0. 8S. 
Alis fuscis: harum anticis versus marginem costalem purpureo 
micantibus ; posticis magna parte dimidii posterioris fulva, 
fascia anali nigra. 
Upper side: male, brown. Anterior wing slightly tinted with purple 
near the costal margin. Posterior wing, without a tail, with most of 
its outer half pale orange, traversed near the margin and the anal 
angle by a curved brown band. 
Under side rufous brown. Both wings crossed at the middle by a 
broad rufous band bordered on both sides with lilac-white. Ante- 
rior wing with some indistinct rufous bands near the base, bordered 
with lilac white, followed towards the anal angle by two other indi- 
stinct bands; a white spot near the apex. Posterior wing with two 
spots, a broad band, and a narrow zigzag band, all rufous and bordered 
on both sides with lilac white ; crossed beyond the middle by a band 
of five brown spots, followed by a narrow zigzag rufous band bor- 
dered on both sides with brown, by a zigzag broad band of white, and 
by a narrow submarginal line of lilac-white.

This species, which is much smaller than the others, is closely 
allied to 7. clarissa. The plush-like scales extend above the higher 
discoidal nervure, as in 7’, teuthras ; the lower disco-cellular nervure 
meets the median, nearly as in 7. clarissa. 
In this genus the nervures, which are generally closely examined 
as affording materials for generic distinction, give most valuable aid 
in determining closely allied species. I have in this paper described 
four new species of a genus which before contained but one, and find 
that they all differ in the position of the disco-cellular nervules. It 
would almost seem as if the variations of these nervures were only 
specific, as I have before found them a valuable aid in separating 
two very closely allied species of Callithea. 
In Terinos clarissa, the lower disco-cellular nervure meets the me- 
dian nervure considerably before the base of its second branch. 
In Terinos terpander, the lower disco-cellular nervure meets the 
median nearly at the same point as in 7’. clarissa, but somewhat nearer 
the base of its second branch.
