greatly lengthened and sagittiform, and, near the posterior margin, a gently curved striga of 
minute arcs. indwing has a delicate dash at the inner costal curve, then a very large 
oblong longitudinally-disposed spot with irregularly-defined edges, narrow at its basal extremity, 
enlarged into a rounded head as it approaches the middle of the costal margin, the exterior 
edge being deeply sinuated and the interior produced into a lengthened process stretching at 
right angles to the disc; behind this an irregular striga extending in an arch across the en- 
tire surface at the interior boundary of the gray anal area, commencing near the middle of 
the costa with a large irregular dot, continued over the disc by four or five wedge-shaped 
marks, and then passing in two slightly diverging acutely flexuose linesto the inner margin ; 
lastly near the hinder margin a double striga, the interior one undulated, enclosing a few oblong 
reddish-br own marks terminating near the external tail, all of a shining white tint, being succeed- 
ed by a large oblong transverse patch of adeep black colour and a stripe closely dotted with 
white, both which are regularly parallel with the posterior margin, while the anal appendage 
itself is covered by a large circular black spot, and two marks of the same colour, edged with 
white, are disposed along the oblique portion of the inner margin. ody brown above and 
hoary underneath. Axtenne uniformly brown to a short ferruginous tip. Zaz/s black with a 
delicate medial line and a white extremity,” (orsfeld, l.c.) FEMALE. UPPERSIDE, both wings 
dull purplish-black, unmarked. UNDERSIDE, doh wings as in the male, except that 
the large silvery band on the hindwing is completely joined to the spot beyond, while in the male 
the two are well separated. The female has three tails to the hindwing, while the male has 
but two. 
My knowledge of this species is confined to a single female collected by Dr. J. Ander- 
son in March on Elphinstone Island in the Mergui Archipelago, and now in the Indian 
Museum, Calcutta. Iam quite unable to say how this specimen, which has been identified by 
Mr. Moore, differs from Mr. Distant’s 7. doswelliana, of which a description is given below.*

1°55 female, x8 inches, DescripTion: “*Mate. Uppersmpe, both wings dark fuscous. Forewing with a 
large patch of dark bluish scales occupying the base of the celf and extending along the inner half, but not 
reaching the outer margin. Hindwing with a very large and similar dark bluish patch occupying the whole 
discal area; ¢az/ and the angulation at the apex of the second median nervule dark fuscous, with the apex 
greyish-white. UNvERSIDE, Jo/h wings warm brownish, shaded with purple. Yorewzng with seven white 
spots, situated one largest and elongate in the cell, one at the end of the cell, and five in a somewhat curved 
series between the end of the celf and the outer margin, of which the third is the largest and extends out- 
wardly ; anda submarginal, somewhat obscure, macular series of smalf greyish spots; towards the inner margin 
the ground-cohour becomes much paler. Hindwing with the basa} half dark purplish, bounded by a media} 
silvery white fascia, which is widest at the abdominal margin and contains some irregular purplish markings; the 
basal dark purplish area also contains two silvery white fasciz, the first short and costal, the second very large, 
extending from near the base of the abdominal margin to the apex, with a concave depression above and a 
narrow media} continuation beneath, which reaches the medial silvery fascia ; beyond this the colour is ochraceous, 
with some purplish marginal spots, bordered with white near the apex, and a broad bluish marginal fascia bor- 
dered with white, extending from about the third median nervule to the anal angle, and containing a darker spot 
at either end. Body above and beneath more or Jess concolorous with the wings. Zegs pale brownish. FEMALE. 
Uppersipe, both wings pale uniform ochraceous-brown. Hindzwing with the costal area paler, ¢az/s and angu- 
Jar [? anal] prolongation darker brown, with their apices greyish. UNDERSIDE, Zoth wings asin the male, but 
brighter in hue and markings.” 
“ Although the female is decidedly larger than the male, it is probable, if a large series could be measured, 
that the diversity is not so great as the above dimensions advocate. The male also possesses a more elongate 
zppearance than the female.” 
“ Considerable confusion has ensued by several distinct species having for a long time been placed under 
one name. Thus Mr. Hewitson (Il). Diurn. Lep., p. 25 (1869) has not only considered 7. timmoleon, Stoll, 
I. rochana, Horsfield, and /. dazarena, Felder, as one species, but has also included the species described here, 
as is evident from the mention of Penang asa locality. In this opinion he has been copied by Mr. Kirby (Cat. 
Diurn. Lep., p. 418 (1871), All these species are, however, clearly distinct and easily determinable by the em- 
phatic markings on the underside of the wings, which, in the Rhopalocera, are the surest guide for specific 
difference.”’ (Distant, 1. c.) 
*“'Tn naming this species I have taken a hint from Dr. Johnson. The great lexicographer once remarked 
to his future biographer, ¢@ Avofos of a moth which fluttered into a candle, ‘That creature was its own tormentor, 
and I believe its name was Boswell.’ This is probably the whole condensed *entomological’ observation 
of Dr, Johnson, and as such may be remembered,” (Distant, |. c.)
