Of this species Thorell remarks, Ann. Mus. Genov. p. 291: 
—“ Feminam unicam, que nondum adulta videtur, ad Bhamd 
cepit Fea.—C. (Leptocteno) valvularis, Van Hass. (Midden 
Sumatra cet. p. 45, pl. v. fig. 12), valde aftinis est hac species, 
colore ventris tamen plane alio facile dignoscenda.”’—It seems 
a pity to base a new species on a young female, confessedly 
so closely allied to another already described form, in a group 
in which the species run so closely together; for Thorell says 
of pulvinatus and fungifer that they also are both closely 
allied to valvularis. Although I have not been able to see 
the type, there are before me specimens identified by 'Thorell 
as CU. trabifer, Thor., from Mr. E. W. Oates’s collection 
from Burmah. These are distinctly different from C. valvu- 
laris, van Hass., judging by the figure of the vulva of the 
latter. They are also quite distinct from any of the other
