Dr. T. A. Chapman on Zizecria, 
Knysna is a synonym of lysimon ; at least, I have ex¬ 
amined no hnysna that are other than lyaimon. A large 
specimen is illustrated (fig. 18). 
]\raha. — Chandda, diluta, sqiialida, oqmlina, marginata, 
((Ibococrvlevs, argia,japonica,al()pe. I enter all these as syn¬ 
onyms of maha, as I do not profess to be able to discriminate 
whether any of them really belong to ossa, and possibly 
hold priority over that name. I take opalma, Poujade, by 
description to be a form of viaha, and it is very unlikely 
to be anytluTig else, but as I have not seen a specimen, 
I cannot assert that it certainly is maha. Specimens 
labelled opalma in B. M. are from China, and are maha, 
opalina, Poujade, is from Thibet. Butler ])laces mar¬ 
ginata, Poujade, and alhocoernleus, Riiber, as synonyms 
of opalma. By Poujade’s description marginata is either 
sangra or indica, probabl}^ the former. Alhocoernleus (from 
Hong Kong), according to Bober’s figure, is a form of 
maha. It is not a Thibetan form, and is probably a variety 
of argia (= maha), the only species mentioned by Kershaw 
(“ Butterflies of Hong Kong ”) to which it can possibly be 
referred. 
In Kershaw’s “ Butterflies of Hong Kong,” Plate VIII, 
fig. 26, called Zizera maha, is Moore’s sangra, a form of 
Z. lahradus; and Plate IX, fig. 8, called Z. argia, is Z. 
maha, of which argia. is a local form, rather than perhaps 
simply a synonym. In the maha group, de Niceville 
(1890) describes five species, but says he does so merely for 
convenience, and that he is satisfied that there is really 
only one species. 
Butler (1900), gives four species that he places before 
lysimon, and we may assume that these belong to the 
maha group. These four species afford ten names and 
synonyms. I have little doubt they belong to the same 
five species that de Niceville gives. 
Bingham (1907), gives only maha, and adds various 
other names as synonyms. 
An examination of the genitalia shows that we have in 
this group two species, one of which is of course maha. 
The other I shall call ossa, without expressing any definite 
opinion that it may not be entitled to be called dilnta, or 
some other of the list of names quoted above. None of 
tlie descriptions of any of the synonyms attributable (more 
or less) to malm are definite enough to enable me to say 
that they refer to ossa and not to maha. Diluta comes the
