and slender and ends in two opposing points like a pair of pincers. As to the egg, in that of eo- 
pithecops the raised lines form triangles laterally, in that of Pithecofs quadrangles. Both genera 
are apparently more or less protected, and are mimiced by certain rare species of Logania ( Gery- 
dine) and Cyaniris (Lycenine ).” (Doherty, 1. c.) 
P. fulgens is a very beautiful little species, of which Mr. Doherty has kindly given me twe 
pairs. It is perhaps one of the most interesting new species that he has hitherto discovered, 
T give below* a description of the genus Una, mihi, which contains a single species oc- 
curring in the Malay Peninsula. The male sex of U. usta, Distant, is alone known up to the 
present. On the upperside it has a strong superficial resemblance to the tailless form of Macaduba 
ardates, Moore, the outline, as also the colour, being much the same ; it also agrees in size and 
shape with JZegisba, Moore. The coloration and markings of the underside are, however; 
quite different from either of these genera, and are unlike those of any Indian butterfly. 
Neopithecops, Distant, is a very remarkable little genus which hasa strong superficial like- 
ness to Pithecops, Horsfield, and moreover similar habits and flightin the perfect state. It 
has the costa of the forewing more strongly arched than in any other genus of this group, thus 
permitting of the wide separation of the costal nervure and first and second subcostal nervules. 
The males have no secondary sexual characters. The genus occurs in India, Ceylon, the Anda- 
man Isles, Burma, and the Malay Peninsula and Archipelago. 
Genus 103.—NEOPITHECOPS, Distant. (PLatz XXVI).

“ FOREWING, small, very broad, elliptical ; [costa] much arched from the base, exterior 
margin convex, fosterior margin of equal length with the anterior, [sinuous]; costal nervure 
extending to less than half length of the margin ; szdcostal nervules very short, first subcostal 
emitted at one-half before the end of the discoidal cell, second at one-third before its end, third 
at one-sixth before its end, fourth at one-half beyond the cell and terminating on the costa 
* Genus UNA, nov. 
Outline of wings almost exactly as in Asanus ubaldus, Cramer. FOREWING, triangular ; costa nearly straight, 
apex acute, outer margin very slightly convex, zzxer margin straight; costal meruure terminating beyond 
the apex of the discoidal cell ; /irs¢ subcostal nervule immediately after its origin anastomosed completely 
with the costal nervure as in the genus Pithecofs, Horsfield, and not again becoming free; second subcostal 
nervule with its origin half as far from that of the first as that of the second is from that of the upper 
discoidal ; ¢4zvd subcostal nervule with its origin a little nearer to the apex of the wing than to the apex of 
the cell ; #zddle disco-cellulay nervule arising from the upper discoidal some distance beyond _ its base, 
concave, upright ; dower disco-cellular as long as the middle, also concave and upright ; second median nervule 
originating some little distance before the lower end of the cell; sxbmedian nervure nearly straight. H1nb- 
WING, coséa slightly arched, outer margin convex, apex rounded, anal angle rather acute, abdominal margin 
nearly straight ; cos¢tad nervure strongly arched at base, thence straight to apex ; Jirst subcostal nervule originat- 
ing some little distance before apex of cell ; upZer disco-cellular nervule slightly outwardly oblique and slightly 
concave, /ower disco-cellular upright, slightly concave ; second median nervule arising a little before the lower 
end of thecell; swbmedian nervure straight ; zaternad nervure recurved, short. Palpz with the first and 
second joints furnished with long bristly hairs, third joint long, naked, acicular. Ayes hairy. Antenne about 
half the length of the costa of the forewing, distinctly annulated with white, with a large spatulate club. Body 
rather robust, not quite reaching to anal angle of hindwing. 
It is very difficult to say to what genus Uma is nearest allied. In neuration it is very close to Pitkecofs, as 
it has the costal nervure and first subcostal nervule anastomosedin the same way, but it differs widely from 
Pithecops in outline and facies. On the upperside U. zsta is nearest to the tailless form of Nacaduba ardates, 
Moore, andto NV. ampsoniz, mihi. In outline it agrees with Azanus ubaldus, Cramer. On the whole it is 
perhaps nearest to Vacaduéa, but the spotted underside of the type species reminds one more of the genug 
Zizera, Moore, than anything else. On account of its neuration, I place it next following Pithecops.

at the end of the cell, and five spots of the same colour in a curved submarginal series. Ainxdwing with two large 
black spots near the costal margin, the outermost with a small fuscous spot beneath it, a small fuscous spot in the

one beneath and near the base of the cell, two near the abdominal margin, one near the anal angle, and four in 
acurved series beyond the cell, and with a double series of pale fuscous, linear, submarginal spots [which are 
continued on to the forewing]. Cé/ia of both wings fuscous. Body and Zegs more or less concolorous with wings.” 
“I place this species provisionally in the genus Zizera, from which it differs by having the first subcostal 
nervule completely anastomosed with the costal nervure [except a short free basal portion]. The typical specimen, 
however, is not only unique, but also not my own property, thus preventing that detailed structural examination 
which is necessary for exact generic determination, but which is liable at the same time to injure the specimen,” 
(Distant, 1. c. in Rhop. Malay.) 
The sex of the type specimen is not stated, it is probably a male.
