288 L. de li^lceviWe—Neiv Butterflies from the Indian Region. [No. 4, 



P. helenus, Linnoeus ; a semi-circular red mark enclosing a round portion 

 of the ground-colour at the anal angle ; cilia black, but with a spot of 

 white in the costal, discoidal, and median interspaces. Underside, both 

 wings blackish-brown. Forewing with the streaks in the discoidal cell 

 as above, but more prominent, some scattered ochreous scales on the 

 disc, and a short pale streak on the margin on each internervular fold. 

 Hindiving with the cream-coloured patch as above, a submarginal series 

 of pale yellow lunules from the costa to the third median nervule, each 

 lunule marked in the middle by ochreous ; an ochreous lunule in the 

 first median interspace, and an almost complete ferruginous-ochreous 

 ring-spot at the anal angle, above which is an elongated patch of whitish 

 scales ; there are a few scattered blue scales on the disc from the sub- 

 median nervure to the discoidal nervule. Cilia black, but marked with 

 a white spot in the middle of each interspace. 



Nearest to P. helenus, from which it may be readily distinguished 

 by its smaller size, narrower wings, and the single red lunule on the 

 upperside of the hindwing only ; on the underside by the short inter- 

 nervnlar streaks on the margin of the forewing, by the large subapical 

 cream-coloured patch of the hindwing being entire, not divided as in P. 

 hele7ius into three well-separated spots by the black veins, by the sub- 

 marginal lunules being pale ochreous-yellow instead of red, by there being 

 no lunule in the second median interspace, a single lunule in the first 

 median interspace (in P. helenus there are two), and in the scattered blue 

 scales on the disc, and the patch of whitish scales in the submedian 

 interspace placed against the submedian nervure. It is altogether a 

 narrower insect than P. helenus, and does not agree in shape with any 

 species known to me, though it is perhaps in that respect nearest to 

 P. demolion, Cramer, to which group, on further consideration while this 

 paper is passing through the press, I have come to the conclusion that 

 it belono-s, in which opinion Mr. Wood-Mason, to whom I have submitted 

 the specimens, concurs. 



Two male specimens of P. noblei exactly alike have been obtained 

 one in February and one in March in the Karen Hills by the native col- 

 lector attached to the Phayre Museum, Rangoon. I have named the 

 species after Mr. B. Noble, the Curator of that Museum, who has 

 generously presented one of the specimens to me, besides many other 

 rarities from the Burma region.
