C. confusa Warr. (14 k). Also closely like chlorargyra, but with the terminal band of the forewing confusa. 
markedly bent inward between the indentation in cellule 3 und that in cellule 5. Ceylon. If this distinction 
is reliable, races of confusa occur also in the Khasis, the Andaman Islands, probably Siam and (together with 
typical chlorargyra ) Malaya. 
C. chlorargyra Walk. (14 k). Described from Sarawak but widely distributed — India, Singapore, the chlorargyra. 
Philippines and again in New Guinea and North Queensland. Abdomen above brown, discocellulars character¬ 
istic, terminal band regular throughout. The obliquely transverse markings of the forewing (on discocellular 
and from hindmargin) are generally less variable than in minutata. 
C. minutata Druce. Variable. The name-type, from Guadalcanal', has the midcostal projection of the minutata. 
border of the forewing very small, the hindmarginal one large and broad, the borders very little mixed with 
white. Probably a mere aberration, possibly a race. — conchylias Meyr. (14 k). Almost always distinguishable conchylias. 
from chlorargyra by the recession of the terminal band from the distal margin in the middle of the forewing, 
which suggests that confusa may be a race of it; but very rare aberrations have this terminal band regular 
throughout, as in conchylias. In such cases, the different ground-colour may be observed when examined in a 
good light (fresh conchylias are absinthe-green or almost apple-green, chlorargyra more bluish — scarcely brighter 
or yellower than “Rinnemann’s green” of Ridgway, but difficult to match exactly) and confirmation is found 
in the short midcostal mark and the form of the white border at the apex. Central markings of forewing shorter 
also than in confusa. Little Kei Island, New Guinea (type) and its islands, the Bismarck Archipelago, Bougain¬ 
ville and Tulagi. 
C. cedilla Prout (14 k). This elegant species differs from chlorargyra in the much shorter antennal cedilla. 
pectinations of the <$. The white element in the borders is less interrupted and has a differently shaped ending 
at the costal margin (2 or 3 mm from apex) and posteriorly (at a similar distance from tornus). British New 
Guinea (loc. typ.), Mindanao, Borneo, E. Sumatra and the Malay Peninsula. 
103. Genus: Pyrrli orach is Warr. 
Similar to the two preceding genera, distinguishable from the second section of Comostola by the simple 
discocellulars, from Comostolopsis by the much more convex distal margin of the hindwing; 1st subcostal of 
forewing from near the apex of the cell or near the base of the stalk of the other subcostals. Both wings almost 
always without cell-dots and lines, but always with red borders. Exclusively Indo-Australian. 
P. caerulea Warr. (12 c). Much larger than the other species and with a distinctive postmedian costal caerulea. 
mark on the forewing. Sikkim, rare. Structurally distinguishable from the rest by having the 1st median of 
both wings separate, not stalked. 
P. deliciosa Warr. Forewing slightly more rounded than in pyrrhogona (141), the red marginal mar- deliciosa. 
kings larger, brighter red, the blackish terminal line rudimentary. Natuna Islands, only the type $ known. 
P. pyrrhogona has already been differentiated in effect from the two preceding, with which it almost 
agrees in its blue colour. The red terminal markings are narrowed, dulled by a (generally thick) black terminal 
line, the paler fringes generally show more or less strong dark spots. Widely distributed, apparently with some 
differentiable races. A few of these have received names. — pyrrhogona Walk. (14 1), described from S. India pyrrhogona. 
and known also from Ceylon, is a small form, with the borders of nearly uniform breadth throughout. The form 
from Formosa has not been separated from this. — turgescens Prout, from the Khasis and Sikkim, has the turgescens. 
border markedly thickened behind the 2nd median of the forewing and slightly at the apex and anal angle 
of the hindwing. — marginata T . P. Luc., from Queensland, seems only distinguishable from the S. Indian marginata. 
type by its larger size. — According to Turner this race has sometimes a red, ochreous-ringed cell-dot on each 
wing, a very unexpected development in this genus, ab. punctata nov. — augustata Prout, from the Loyalty punctata. 
Islands, agress with marginata in size but has the borders still narrower, scarcely expanding into lunules between augustata. 
the veins. 
P. comuta Warr. (14 1) possibly represents a further race (or series of races) of pyrrhogona, but is readily cornuta. 
distinguished by the “horn” from which Warren named it, a small posterior projection from the boi’der of 
the forewing which suggests that of Comostola sect. 2. The name-typical form, from Fergusson Island (type), 
Goodenough Island, the Louisiades and New Guinea, has the “horn” moderate or small. A few specimens from 
Borneo have it perhaps smaller still. — ab. viridescens nov. is much less blue than the type, approaching (though viridescens. 
not quite reaching) the yellow-green of viridula. The <$ of this aberration, from Mt. Goliath, presents such 
a sharp colour-contrast to most of the material from the mainland of New Guinea that one might believe it 
a separate species, but some of the island forms are similar or intermediate. — pisochlora subsp. nov. (14 1). The pisochlora. 
green colour seems here constant and the race further differs in having all the red markings somewhat extended.
