PAN.ETHIA.— URAPTEKYX. 49 



PAN.ETHIA, Gum. 



Panaethia iridicolor. (Plate CXIII. fig. 3.) 

 Panaetkia iridicolor, Bailer, Ann. § Mag. Nat. Hist. ser. 5, vol. vi. p. 227. n. 03 (1880). 



J 1 $ . Wings above pale emerald-green, crossed in the middle by a broad angulatcd and 

 widely sinuated chrome-yellow belt; a widely undulated discal stripe, white internally and 

 yellow externally ; external border washed with yellow, the veins and a series of internervular 

 longitudinal rays beyond the discal stripe blue-black : primaries with a large and nearly 

 complete annulus at the base, its inner edge yellow and its outer edge white ; a small spot at 

 the base of the costal border and a curved transverse line on the discocellulars blue-black : 

 secondaries with the upper half of the discocellular slightly blackish : body bright yellow : 

 frons greenish, bright green just in front of the ajitennie, the latter testaceous with the scapi 

 white; posterior margins of abdominal segments silvery white. Under surface pure white ; 

 primaries with a dark-green line on the discocellulars. Expanse of wings 59 millim. 



Darjiling (Lidderdale) . 



This beautiful and delicate species is nearer to P. hernionata of Guenee, from North 

 China, than to any other known species; it is, however, entirely dissimilar in colour to any 

 moth vet described. 



UllAPTERYGIDiE. 



URAPTERYX, Leach. 



Urapteryx primularis, sp. n. (Plate CXIII. fig. 4.) 

 Urapteryx picticaudata, Butler (nee Walker), Jburn. Linn. Soc, Zool. vol. xvii. p. 11)8. n. 3 ( 1883). 



Nearest to U. sciticaudaria; but considerably larger, of a bright primrose-yellow 

 colour, with broader bands across the wings, and with the disk of the wings more strongly 

 striated with brown; the caudal process on the secondaries comparatively broader and 

 shorter. Expanse of wings 63 millim. 



Nepal; Darjiling (Russell, 3fc.). 



In the Supplement to his Catalogue Mr. Walker wrongly identified a Darjiling example 

 of this species with his U. picticaudata, and remarked — "This and U. sciticaudata (sic) are 

 varieties of one species, and are connected by U. multistrigaria with U. sambucaria." 



U. multistrigaria is a white species, and belongs to the same group as U. maculicaudaria of 

 Japan and not to the U.-sambucaria group, so that it does not form a connecting-link between 

 the present species (which Walker had before him) and U. sambucaria, or U. sciticaudaria 

 and U. sambucaria; indeed the two latter are, as Walker says, "closely allied, but the former 

 may be distinguished by the additional line on the fore wings, and by the longer tails of the 

 hind wings."
