" Lhatso differe do tous les autrcs par la teinte jaunatre de scs tachcs en dessiis, Ic lavis orange 
qui s'etend sur Tangle anal, la couleur jauue ocracee qui fait le fond dea ailes iuferieures efc 
de I'apex des suporioures en dessous. 
" De plus, les ailes sont plus opaques, les parties noires plus accentuc'cs, ct la forme des ailes 
moins arrondie que dans davidis ; elle est eependant moins anguleuse quo chez buddjia. 
" Tse-kou (Thibet), K. P. Dubernard." {OhertMu; I. c.) 
This appears to bo a very distinct species. M. Oberthiir {I. c.) also records 
C. huddha from the same locality, but I am inclined to think that this 
is an aberrant form of C. davidis, a species he previously confounded -with 
C. huddha.

" M(de. Upperside dark bluish green. Auterior wings -with the cell crossed by three black bars, 
that nearest the base nearly obsolete ; beyond the cell, across the disk between the veins, is 
a curved row of indistinct greyish spots, the second and third of which are elongate ; a sub- 
marginal row of sagittate grey markings, elongated inwardly to the extent of about one third 
of the \^■ings, those towards the apex being more elongate and narrower than the others ; 
there are no spots on the outer margin. Posterior wings more bluish green than the anterior 
wings and without grey markings, except three small hastate lines near the apex, with grey 
lines at their base, the lowest almost obsolete ; beneath these, on the outer margin between 
the veins, is a series of black hastate spots. 
" Underside: anterior wings bluish black, with the spots beyond the cell more distinct and the bars 
crossing the cell and a small spot beyond violaceous ; the sagittate markings as on the 
upperside, but more distinct. Posterior wings olivaceous, the hastate spots at the apex as 
on the upperside, and the series of marginal black spots faintly and very narrowly bordered 
with white. 
" Expanse of wings 2| inches. 
" One example. Omei-shan, Western China. 
"Near to D. nesimachiis, Boisduval, but considerably less ma'culate." 
(Grose Smith, I. c.) 
A figure of this species will be given in a future part of ' Exotic Butterflies,' 
by Grose Smith and Kirby.

" Upperside olivaceous green. Anterior wings crossed be}'ond the middle from the costal to the 
submedian nervures'by a pale greenish-yellow band, widest on the costa, narrowest between 
the two upper median nervules ; a small yellowish somewhat elongate spot near the costal 
margin, and a larger oval spot of same colour at the outer edge of the band beneath it ; the 
space between and on each side of the dark bars which cross the cell is also pale greenish 
yellow. Posterior wings with a pale greenish-yellow curved band following the contour of
