species or for the ja/ra of Godart. The latter is clearly synonymous with C. freja, but as 
Mr. Butler has spelt this name differently to what Godart did, it can be retained for his (Butler’s) 
species. 
The figure shews both sides of a male specimen of this species from Ceylon -in my 
collection. 
I give below a description of a remarkable genus and species occurring in the Malay 
Peninsula‘and Borneo,* 
The eighth division that I have made in the Indian Zycenide I have called the Horaga 
group ; it contains six genera within Indian limits, and one in the Malay Peninsula. In this 
group of genera both sexes of all species have three tails to the hindwing. ‘They can be split 
up into two subgroups each containing three Indian genera. The first has the middle tail short, 
under a quarter of an inch in length, all the tails filiform and not ciliated ; the forewing with 
two subcostal nervules only. The second subgroup has the middle tail longer, over a quarter 
of an inch in length, and all the tails strongly ciliated ; one genus has three subcostal nervules 
to the forewing, the other two genera have two only. It is probable that all the genera are 
strictly oriental, although it is possible that some of them may be found in Africa.

in some lights ; marginal line black. AHixdwing witha large anal black patch bordered above and below 
by slender white lunules. Cz/ia and tail white. UNDERSIDE, both wings entirely white. Forewing with a 
very indistinct slender black discal broken line and linear submarginal line. Aindwing with a similar slender 
discal and submarginal sinuous line, and marginal lunules ; a large inner and outer anal black spot and two 
smaller intervening spots, each speckled with metallic-green scales. FaMALE. UPPERSIDE, both wings violet- 
brown, with broad white borders to black anal patch.” UNDERSIDE, doth wings as in the male, (JZoo0re, |. c.) 
“* Kornegalle and Lower Ambegamoa. Scarce’ (Wackwood). 
* Genus Ritra, nov. Allied to Chevitva, Moore. Male differsin the outer margin of the forewing being 
slightly concave not straight, and in having a large round silky patch of scales differently formed to those on 
the rest of the wing in the middle of the wing, the patch occupying the outer end of the cell, bounded pos- 
cononly by the first median nervule, anteriorly by the upper discoidal nervule. Type, Sithon aurea, 
ruce. 
As far as Iam aware, this genus contains but a single species, which occurs in Borneo and the Malay 
Peninsula, and of which the male alone is known. On the upperside it is coloured just like a male Cuveiis, 
Hiibner, being of an orange-coppery shade, the forewing with the large silky patch above described concolorous 
with the rest of the wing, but noticable at once by the scales of which it is formed catching the light in different 
directions ; it is also strongly visible when the butterfly is held up to the light owing of the opacity of the 
scales. The hindwing has the anal region white, marked with two black spots, the tails white, witha 
black medial line.

UprersIDE, oth wings dark orange. Forewing with a silky spot at the end of the cell. Hivdwing with the anal 
angle, which is marked with two black spots, and the ¢aéZ white witha black centre. UNDERSIDE, doth wings 
sooty-brown. Hindwing with the posterior half white, crossed by two broken black bands, the lower one slightly 
marked with blue. Allied to Wyrina orpheus, Felder,” from Luzon. (Druce, 1. c.) 
On the upperside both wings have a fine anteciliary black line on the outer margin, the cilia of the 
forewing black, of the hindwing white. On the underside the inner margin of the forewing is paler than 
the rest of the wing, in the hindwing the outer series of black spots are centred with metallic blue, and 
there is a fine anteciliary fuscous line. 
There isa single male of the species captured by the late Herr Kiinstler in Perak in the collection of the 
Indian Museum, Calcutta. The species is not included in Mr. Distant’s ‘* Rhopalocera Malayana,”’ this speci- 
men was sent to him, but he returned it unnamed, stating that as the tails were wanting it would be better to 
await the receipt of a perfect specimen before identifying it. Ihave but little doubt, however, that I have 
correctly named the specimen. The JZ. orfheus of Felder, from the Philippines, is quite a distinct species, 
and moreover apparently lacks the male sexual patch of scales on the forewing, and, therefore, in my opinion, 
should be placed in a different genus. Its description is appended.*

the veins and the margin of a delicate copper-yellow, the forewing of the female yellowish-brown on the 
disc. Hiadwing in both sexes black in the anal region, in the male with two spots, in the female with three 
much larger spots marked with white. UNpeERsSIDE, doth wings whitish, margined with yellow. Hindwing with 
a very oblique macular streak, and with three shapeless spots in the anal region, sprinkled with metallic leaden- 
green atoms, beyond this, black.”’ 
‘* This extraordinary species has the size of M. jaffra, Godart. On the waderside it is very like 
M. | Neocheritra\ amrita, Felder, from Malayana, but it differs much from it in the straightness of the wings, in 
the arrangement of the veins, and the form of the palpi. As regards the branching of the subcostal nervure of 
the forewing, it is allied to 17. [Tajuria] longinus, Fabricius (which we referred to erroneouly as pseudolonginus 
in our Lepidoptera Malayica, in Wien. Ent. Monatsch., vol. iv, p. 395), but really it has palpi extremely like 
those of M7, [Zooxylides] tharis, Hiibner. We have seen two females and one very lovely male specimen 
collected by Mrs, Anna Semper.” (/e/der, 1. c.)
