LYCANIDA. THAMALA, 387 
Of this rare species I have only seen three specimens taken by Dr. J. Anderson in the 
Mergui Archipelago in December, January and March, a male from the Khasi Hills taken 
by the Rev. Walter A. Hamilton, and a female from Selangor in the Malay Peninsula, The 
latter differs from the two females from Burma in having tle upperside of the forewing entirely 
smoky-brown, the orange patch being wholly wanting ; on the hindwing the white irroration 
at the anal angle is much reduced. Mr. Doherty obtained a single specimen at Myitta in 
the Tenasserim Valley, Burma. As far as I know it has no near allies, and is very easily 
recognised. It appears to be a very rare species. 
The figure shews both sides of a male specimen from the Khasi Hills in my collection, 
Gonus 149.-THAMALA, Moore. (PLate XXVIII), 
Thasmala, Moore, Proc. Zool. Soc. Lond., 1878, p. 834. 
“MALE and FEMALE. FOREWING, short, broad, trigonate 3; costa convex at base, afex 
moderately acute, exterior margin slightly oblique and recurved, fosterior margin nearly straight, 
anal angle acute ; discotdal cell broad, short ; subcostal nervure four-branched, first, second and 
third arising before the end of the cell, fourth at its end; désco-celular nervules slightly 
curved outwards ; [/ower] radial from their middle ; median nervure three-branched, two upper 
branches contiguous at base from the end of the cell. HINDWING, elongated posteriorly, narrow 
and quadrate below the anal margin ; with two narrow lengthened tails, one at each angle; 
exterior margin slightly waved. Bopy moderate. Antenne stout, uniformly thickened to 
apex. Palpfi long, squamous, second joint projecting half its length beyond the head, apical 
joint slender. Zegs squamous, femora slightly pilose beneath.” 
“ Differs from Deudorix (D. melampus (jarbas, Fabricius), and D. efijarbas, Moore) in its 
shorter and broader forewing and longer hindwing, the forewing having only four subcostal 
branches (there being five in both the above species), and in the antennz being more robust.” 
(Afoore, 1. c.) Deudorix jarbas has been placed by Mr. Moore since the above description was 
written in his genus Vadzsepfa, and is distinct from melampus, Cramer, which Mr. Moore now 
places in his genus Baspa. I include both species under the genus Rapala, Moore. 
Iam indebted to Mr. W. Doherty for the gift of a male specimen of 7. marciana, 
Hewitson, from S.-E. Borneo, which has enabled me to bleach one pair of wings and to 
carefully examine the neuration. In the forewing the costal nervure ends opposite to the apex 
of the cell; the base of the second subcostal nervule is half as near to the base of the first 
subcostal as to the base.of the upper discoidal ; the discoidal cell is long, extending to more 
than half the length of the wing, its outer end rounded ; the middle disco-cellular nervule 
springs from the upper discoidal some little distance from its base, is convex and slightly 
outwardly oblique ; the lower disco-cellular is a little longer than the upper, upright, straight, 
and forming nearly one straight line with the upper; second median nervule given off some 
little distance before the lower end of the cell; submedian nervure recurved, with, in the male, 
a narrow glandular patch of scales differently formed to those on the rest of the wing lying on 
either side of the nervure for a short distance from its origin, below which the inner margin of 
the wing is slightly outwardly bowed. In the hindwing the costa is well arched and formed 
to cover the glandular patch on the forewing, and following its outline ; the costal nervure 
is much curved at the base, slightly so thence to the apex of the wing ; the first subcostal nervule 
considerably arched, arising at a moderate distance before the apex of the cell; disco-cellular 
nervules straight, of equal length, outwardly oblique, the upper slightly sinuous and rather 
more oblique than the lower; second median nervule given off rather near to the lower end 
of the cell ; submedian nervure straight, not extending to the apex of the inner tail; internal 
nervure very long, slightly curved. The antennz are long, more than half as long as the costa 
of the forewing ; the palpi of the female much longer than those of the male ; the eyes are naked, 
As far as I am aware, the genus 7amala comprises but two species, which most pro- 
bably are reducible to one; AZ. ménzata, Muore, occurring in Burma, and JZ. marciana, 
Hewitson, in Malacca, Sumatra, and Borneo. On the upperside, the male of both species is
