(??. On comparing tlie types of subocellala, turbata, thwaitesi and Bntler's 

 mowei (not the same as Boisduvars moorei, which has priority) we find that thoj' 

 belong to one species. The Malayan individuals which we liave seen do not seem to 

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

 Ceylonese ones. There is considerable individnal variation in the markings both on 

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



is apparently never qnite absent. Foretibia with a few spines at and near apex 



exteriorly ; hindtiliia 1 to ',' mm. lonaer than, long apical spur three-lifths the length 

 of, the first tarsal segment. 



(?. Eighth abdominal stcrnite with an obtnse mesial lobe which is very faintly 

 sinnate ; the edge of the lobe internally incrassato to two tubercles which stand 

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

 (PI. XXXI. f. 10) 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 jirodnced distad into an irregularly spatulate process, of which the upper edge 

 is dilated into a large triangular tooth. Penis-sheath withoirt e.xternal armature ; 

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

 teeth (PL XXX. f. 1). Tenth sternite (T\. XXIII. f. 13) separated into two lobes 

 which 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 than in 0. substrigilis, horn long ; a 

 white dorso-lateral line from pronotura to horn, seven white oblique side-bands, 

 a series of red dorso- and ventro-lateral jiatches, besides some lateral dots on the 

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

 more whitish ; edges of anal segment yellow. 



Pupa (fig. by Moore, I.e.) insufficiently known, slenderer than in SKb.ifriyiUs.
