c??. On comparing the types of suboccllata, tiirhata, thiixiitesi and Butler'.s 

 moorei (not tlie same as Boi-sdnval's vioorei, wliicli lias priority) we find that they 

 l)elon<r to one species. The Malayan individuals which we have seen do not seeni to 

 present any constant character by which they conld be distingnished from the Indo- 

 Cevlonese ones. There is considerable individnal variation in the marlnngs both on 

 the fore- and hindwing. The blackish olive stripe across the mesothoracic tegula 



is apparently never quite alisent. Forctibia with a few spines at and near apex 



exteriorly ; hindtibia 1 to "2 mm. lonu'crthan. long apical spur three-fifths the length 

 of, the first tarsal segment. 



c?. Eighth abdominal sternite with an obtuse mesial lobe which is very faintly 

 sinuate ; the edge of the lobe internally incrassate to two tubercles which stand 

 closely together, not being visible in a ventral view (PI. XXII. f. 23). Harpe 

 (PI. XXXI. f. lU) extending basally from the ventral to the dorsal edge of the clasper, 

 this ventro-dorsal ridge low, produced at end into a long pointed process which evenly 

 curves ventrad ; there is generally a tooth at the base of this hook ; ventral part of 

 harpe produced distad into an irregularly spatnlate process, of which the upper edge 

 is dilated into a large triangular tooth. Penis-sheath without external armature ; 

 duct with a ribbon-like organ which is densely beset with minute, sharply pointed, 

 teeth (PI. XXX. f. 1). Tenth sternite (PI. XXIII. f. 13) separated into two lobes 

 whicli are somewhat widened at end and incline towards each other. 



¥ . Eighth tergite mesially less chitinised than at sides, but not membranaceous, 

 shallowly sinuate. Vaginal cavity (PI. XV. f. 1) large, the ridge before it irregularly 

 folded, mesially sinuate, continued laterad to the base of the tergite, lateral part 

 higher, hollow at its ventral end, forming a kind of roof over the end of the lower 

 ventral ridge. 



Larva (fig. by Moore, I.e.) more slender tiiau in (>. .tiib.sfrn/ilis, hurn hmg : a 

 white dorso-lateral line from pronotnm to liorn, seven white oblique side-bands, 

 a series of red dorso- and ventro-lateral ])atches, besides some lateral dots on the 

 first segments, dorsal part of larva green between the white dorso-hiternl lines, rest 

 more whitish ; edges of anal segment yellow.
