108 LEPIDOPTERA INDIOA. 



witli wMte. Botli wings with, a broad transverse outer-discal powdery bluish-grey 

 fascia, wbicb is traversed by a submarginal slender black denticulated line, this 

 line being more or less obscurely defined on tlie forewing, tlie fascia itself widening 

 on the biudwing, and extending to the outer margin towards the anal angle ; the 

 ordinary basal marks black and obscure; on the forewing, in some specimens, a 

 small very obsolescent pale discal spot is apparent between the upper and middle 

 median veinlets. Underside yellowish-ochreous, the outer margins slightly suffused 

 with brown ; basal marks slightly defined ; crossed by two discal black diffused 

 sinuous fasciae, which are more or less defined, the inner fascia generally being less 

 distinct, and on the forewing sometimes showing a small pale whitish semi- 

 diaphanous spot (slightly visible in some few specimens also on the upperside) 

 between the upper and middle median ; the outer line most defined on the forewing, 

 the portions increasing in width posteriorly. Body, palpi, and antennse above dark 

 brown, beneath and the legs pale yellowish-ochreous ; antennae tipt with reddish 

 beneath. 



Female. Upperside olivescent ochreous-brown ; basal marks blackish-lined, 

 obscure. Both wings crossed by a discal brownish-grey powdery sinuous fascia, the 

 inner edge of which on the forewing bears a sullied-whitish lunate spot between the 

 upper medians and more or less apparent pale lunate spots above it to the subcostal ; 

 outwardly the powdery fascia, on both wings, is traversed by a more or less defined 

 blackish-speckled narrow sinuous band. Underside yellowish-ochreous; basal marks 

 black-lined. Both wings crossed by a discal and a submarginal moi'e or less 

 distinctly-defined blackish or dusky-brown narrow sinuous diffused line, the discal 

 being most diffused, the outer sometimes dentate. Forewing also with a black 

 ringlet-spot below the cell, and a series of pale whitish discal spots, as on the 

 upperside. Eindwing with the abdominal border washed with pale bluish-grey. 



Expanse, S 2^% to 2^%, ? 2^% to 3i^o inches. 



Habitat. — Sikkim ; Bhotan ; Assam ; Silhet ; Cachar ; Lushai Hills ; Upper 

 Tenasserira. 



We have restricted this species to the form described and figured as above. 

 The typical male (Plate 231, fig. 1, la), and that which we here describe as the 

 female (fig. 1, b, c), are from Sikkim specimens. The insect which was described 

 and figured as the female of Kesaoa, in 1859 (I.e. fig. 3), is, according to our present 

 determination, strictly referrable to the next species (Eangoonensis), and is identical 

 with the type described by Colonel Swinhoe. 



Distribution. — " This is one of the commonest species in Sikkim, at low 

 elevations, from 2000 to 3000 feet, and flies from April to December " (de Niceville, 

 Sikkim Gaz. 1894, p. 144). " It occurs eastward as far as Upper Assam, also in 

 Silhet and Cachar " {id. Butt. Ind. ii. 213). We possess several specimens of both
