36 LYCAINID.®. i 4 ZARONA, 
Z. bradamante, Doherty, MS., occurs in Lower Siam. Its description is appended.* It was 
drawn up from a single specimen. All the species of the Poritia group occurring in the 
Malay Peninsula seem to be extremely rare. 
T append as a foot notet a description of the genus Deramas, Distant, which belongs to 
the Poritia group. This group is a very small and interesting one: it would be very desirable 
to monograph it, and to place in their proper genera the various species which have been 
described as Poritia, but which do not belong to that genus. 
* Zarona bradamante, n.sp.. Doherty, MS. Hapirat: Lower Siam. ExpanseE: Not given. Descrip- 
TION : ‘* MALE. Uprersipe, doth wings black, basal part of forewing and half the hindwing bright bluish-green, 
the tint varying in different lights. (This is caused by the scales being slightly bent downwards at the end. the 
basal three-fourths being green. the terminal fourth blue. Viewed from certain directions, only the blue tips 
of the scales are visible ; from others, only the green bases.) This green space occupies the lower part and end 
of the discoidal cell, the basal part of the median interspaces, the interno-median interspace where it projects to one 
fifth from the margin, and the interspace from the submedian nervure to the inner margin, not extending so 
far outwards ; an oblique dark streak in the green in the middle of the interno-median interspace, and a longer 
one along its upper edge; the veins slenderly black. Hindwing has the green colour extending over most of the 
disc from the second subcostal nervure to the submedian nervure, marginal line black, the discoidal cell powdered 
with green basally; a black submarginal transverse streak in the interno-median interspace, the veins not 
perceptibly black ; abdominal margin clothed with long hairs. Cz¢/a black. UNDERSIDE, doth wings, ground dark 
rufous-brown with a slight violet lustre, paler outwardly, a transverse discal line, of darker streaks bordered 
outwardly with paler, the three upper streaks on the forewing placed beyond the line of the others, those on 
the hindwing placed very irregularly ; an obscure series of paler lunules, somewhat irregular on the hindwing, 
that inthe interno-median interspace broadly sagittate, enclosing a white-powdered spot ; a paler line close to 
the margin ; marginal line anally on the hindwing black, inwardly defined with whitish. C7/a rufous. PREHENSOR KS, 
seen from the side. Umcus quadrate, the angles rounded, branches very slender. hooked at the tip, angled in the 
middle. Clasfs irregularly quadrate at the end, the lower angle acute, a long hirsute process or beak deflexed 
at the tip, proceeding from the upper angle. above the base of which is a tubercle.” 
“* One male, taken in deep forest at Kulim, State of Kedah, Lower Siam, not much above the sea level. 
It differs from Deramas livens, Distant, in the colour of the upperside, which is bluish-green instead of ‘dark 
cerulean-blue,’ in the colour of the underside which is dark rufous-brown instead of ‘ pale brownish-ochraceous, 
suffused submarginally with grey, in the presence of the two black marks on the forewing above, and in 
the absence of the sexual tuft.” (Doherty, MS.) 
Mr. Doherty placed this species in Mr, Distant’s genus Devamas, but as that genus possesses a tuft 
of hairs in the male which is lacking in bradamante, 1 have thought it better to place it in Zavona, mihi. 
Mr. Doherty gives the following description of the structural characters of his type specimen of é6radamante. 
These differ in several particulars from the two species I have placed in Zarona, and hence it appears to me 
probable that dradamante should have made the type of anew genus. i x 
“ Forewing with the costa strongly convex at base, thence straight nearly to apex, not emarginate in the 
middle as in Porttia, Moore; apex rather acute ; outer margin slightly convex, inner margin strongly convex 
near the middle; costal nervure thickened, strongly bent in the midd!e. ending two-fifths before the apex ; the 
first subcostal nervule short, slender, originates one-third before the end of the discoidal cell. anastomoses with 
the costal nervure not far from its origin and does not again separate from it; second subcostal from one-sixth 
before the end of the cell; third subcostal originates at two-fifths of the distance between the cell and the 
apex ; fourth subcostal thence halfway to the apex; upper discoidal nervule from the upper angle of the cell ; 
middle disco-cellular nervule less than one-third as long as the lower; median nervules with their bases 
remote from each other, the second median originating well before the end of the cell; submedian neryure, 
Straight ; discoidal cell widest two-thirds fromthe base, the end regularly concave. Hindwing elongate, 
triangular, the costa, apex and anal angle rounded, the outer margin nearly straight for some distance, no 
tails ; costal nervure robust at base, strongly bent beyond it, not attaining the apex ; first subcostal nervule 
originates considerably before the end of the cell; second median nervule from its end; upper disco-cellular 
nervule half as long as the lower; discoidal cell with its end oblique ; internal nervule rather long. Antennz 
rather thick, gradually clavate, the end abrupt, articulations about forty-four. Palpi with the Jast joint one- 
third as long as the preceding one, slender, acicular, with few scales. Eyes naked. Hindlegs with the first 
joint of the tarsus enlarged, thicker and about as long as the tibia, longer than the other joints united, the 
pulvillus very broad. Forelegs as in Massaga, Doherty, the tibia and tarsi thicker, the tarsi less clavate, with 
longer spines, not articulate ” (Doherty, MS.)

“Closely allied to Portia, Moore. FoREWING, differs in possessing five instead of four subcostal nervules ; 
Ji st subcostal nervule very short, emitted at about one-third before the end of the discoidal cell, and joins 
the costal nervure ; second subcostal emitted nearer first than third ; ¢/zad subcostal from the end of the cell; 
Sourth subcostal bifurcating from third at about half its length; #4 subcostal bifurcating from third about 
midway between the base of the fourth and the apex of the wing.’”” (Distant, |. c. in Rhop. Malay.) : 
As far as is known but a single species comes into this genus. D. ivens, Distant, 1s described as 
possessing a cellular tuft of long hairs on the upperside of the hindwing in the male. It is recorded from Singa- 
pore. On the upperside the lower discal area of the forewing occupying rather less than one-third the total 
area of the wing and the disc of the hindwing are rich blue ; the underside is very inconspicuously marked.
