390 LYCAINIDAL. HYPOLYCANA, 
Kirby in his “Synonymic Catalogue,” pp. 406 and 782, included also twenty-eight species, 
of which twenty-seven are identical with those of Hewitson’s list. Of these species, eight only 
Indian, two being admitted into the genus as herein restricted, three (or rather two, as 
othona and eltola are opposite sexes of one species) are here placed in another genus (CH/zarda, 
Moore), /reja is placed in the genus Cheritra, Moore, while améa, Kirby, is placed in the gentts 
Sinthusa, Moore, and eto/us becomes the type of anew genus, Ze/tus, dz Nicéville, Two species 
(tharis, Hiibner, and z/gzrtca, Moore) do not appear in Hewitson’s or Kirby’s lists of 
fypolycena ; the former species is in this work made the type of a new genus (Zooxylides), while 
the latter remains in Hyfolycena. In 1884 Mr. Moore redescribed the genus, enumerating seven 
species as appertaining to it. One of these, 4. andamana, Moore, is strictly conspecific with 
another species, H. ery/us, Godart ; while Mr. Moore omitted from the genus his H. nilgirica, 
which he erroneously placed in the genus Chliaria. Of these species, now reduced to six—H. 
tmolus, Felder, from the Philippines ; 4. sifylus, Felder, from Amboyna; H. tharrytas, Felder, 
from Luzon ; 4. astyla, Felder, from the Philippines ; A. evy/us, Godart, and HZ. thecloides, 
Felder, both Indian—the two last are included in this work in the genus Ayfolycena. Mr. 
Distant added two species tothe genus, ¢havis, Hiibner, and efo/us, Fabricius, but, as stated above, 
I have made each the type of anew genus, as neither species is strictly congeneric with AHyZo- 
lycena ; the latter of these two species has lately been placed by Mr, Moore in his genus Cheritra, 
but erroneously, as in that genus the forewing has three subcostal nervules, while efo/us has but 
two. This completes the list of the genus as now restricted, unless, as Mr. Distant surmises, 
there are a number of strictly congeneric species occurring in Tropical Africa, which should be 
added to it, as was done by Mr. Hewitson. Mr. Trimen in his ‘‘ South-African Butterflies,” 
takes a very comprehensive view of the genus (though he restricts it to species with two sub- 
costal nervules to the forewing), as he includes init species with three, with two, and with 
one tail. He admits five species as occurring in South Africa. 
H. erylus, Godart, has a very wide range, and is certainly the commonest species of the 
genus where met with. A. wi/eivica, Moore, has the most restricted range of the Indian 
species, occurring only in the Nilgiri hills and in Ceylon; while A. thecloides, Felder, is 
confined to Burma, the Malay Peninsula, and the Nicobar Isles ; both species are rare even 
where they are found at all. A. evy/us hasa glandular discal patch of modified scales in 
the middle of the disc of the forewing on the upperside in the male, which the other species 
lack. This patch appears to be superficial only, and the wing-membrane to which it is 
attached is not affected to the extent it is in many genera of the Zycenide, in which that portion 
of the wing to which the modified scales are attached is raised on the under surface into a 
shallow projecting disc, and correspondingly depressed on the upperside. There is no sign 
of the membrane being affected in any way in Z. evylus. 
Key to the Indian spocies of Hypolyccona. 
A. Male with glandular discal black patch of modified scales on upperside of forewing. Male, upperside, 
deep blue; female, upperside, hindwing smoky-black, with irrorated white patch at anal angle. 
944. H. erytus, Sikkim, Assam, Burma, Andamans, Malay Peninsula and Archipelago. 
B. Males without secondary sexual characters. Males, upperside reddish-brown, glossed with purple in 
some lights, with orange markings at anal angle of hindwing on upperside. 
a. Both sexes with markings on underside bright ochreous. Sexes alike in coloration. 
945. H. THECLOIDES, Mergui Archipelago, Nicobars, Malay Peninsula.
