28 LYC/ENIDA. ALLOTINUS. 
inclosure [claus] of the cell, the wfper disco-cellular nervule distinct. Zegs rather long, 
slender, acicular, the hinder tibize nearly equal to the femora.” yes naked. 
‘‘Very distinct from JZiletus, Westwood, on account of the structure of its tarsi.” 
(Felder, 1. ¢.) 
In the forewing the costal nervure terminates about opposite to the apex of the discoidal 
cell; the first subcostal nervule is given off long before, the second a little before the apex 
of the cell, the third subcostal is long and is emitted about midway between the apex of 
the cell and of the wing; the upper discoidal nervule emitted exactly at the apex of the cell ; 
the other neural characters much as in Gerydus, Boisduval, and the prehensores of the 
male similar: that sex also has no secondary sexual characters. 
Allotinus differs from Gerydus in having the tarsi rounded, not widened and compressed, 
and in the position of the upper discoidal nervule of the forewing, in this latter character it 
differs also from Paragerydus. It differs from Paragerydus in having the third subcostal 
nervule of the forewing long, and emitted at one-half between the apex of the discoidal cell 
and the apex of the wing, while in Puragerydus it is short, and is emitted at one-third before 
the apex of the wing only. Ad/otinus agrees with Paragerydus in the structure of the legs. 
Dr. Felder described five species in this genus, inhabiting Singapore, Java, Celebes, 
and Luzon. Of these Mr. Distant takes sadviolaceus as the type, while Mr. Butler following Mr. 
Scudder takes fallax, which “ emits the third and fourth subcostal branches from a long foot 
stalk beyond the cell” of the forewing, while szdvio/aceus has it ‘‘ emitted at or near end of cell.” 
Four species occur within strict Indian limits, and two of these are the largest of the 
group. The males of these two species above are dark brown, with a pale fascia on the 
forewing ; the female of one species is white on the upperside, the apex, outer margin, 
posterior angle, and part of the inner margin of the forewing, with the costa of the hindwing 
black ; the female of the other species is very like the male of the first, having a curved pale 
ochreous fascia on the upperside of the forewing on the disc, Both species in both sexes have 
an immense number of minute and larger-sized brown dots and spots sprinkled over the 
underside. AJlotinus alkamah, Distant, is altogether different from A. drumila, Moore, 
and A. multistrigatus, mihi: it is only a little more than half the size, the upperside of 
both sexes has a large discal and basal patch of violaceous in both wings, and the markings of 
the underside are quite different in character, the ground-colour being profusely sprinkled with 
ochreous-brown spots very similar to those in Parvagerydus horsfieldi, Moore, Allotinus nivalis, 
Druce, is again very distinct : both sexes are plain brown on the upperside without any mark- 
ings whatever, the underside is white, spotted and mottled sparingly with brown, but in quite 
a different manner from 4. a/kamah. It is also smaller than that species. A. mudltistrigatus, 
A. alkamah, and A. nivalis in both sexes have the apex of the forewing simply acute, the 
outer margin entire (4. ziva/is has it scalloped), the inner angle somewhat rounded. A, drumila 
has the apex highly acuminated, the outer margin scalloped, and the inner angle greatly pro- 
duced, The genus is probably strictly confined to the Indo-Malayan region, 
Koy to the Indian species of Allotinus.
