NYMPHALID^. NYMPH ALIN/E. BYBLIA. 13 



The late Mr. A. de Roepstorfif sent several specimens of both sexes of this species to the 

 Indian Museum, Calcutta. Captain C. T. Bingham has taken a single male in the Meplay 

 Valley in October, which differs from South Andaman specimens on the upperside in having 

 the marginal blue band obsolete, and in its much lighter colouration on the underside. 

 E. horsfieldii also occurs in Java. 



The figure shows both sides of a South Andaman male in the Indian Museum, Calcutta, 

 A very beautiful species of the genus has been described from Malayana ; the original 

 description is given below.* It is quite distinct from E. horsfieldii, the ground-colour of the 

 upperside being entirely rich ultramarine-blue to judge from the published figures of it.

"Body, slender, moderately woolly ; 7vings, of moderate size, of a rich orange colour above 

 with black markings, but not ocellated, alike in both sexes. Head, rather small, finely hairy 

 in front. Eyes, prominent, naked. Palpi, elongate, rather slender, not compressed, finely 

 hairy, porrected considerably further than the length of the front of the head ; the terminal 

 joint horizontally porrected, not elevated above the level of the middle of the eyes ; middle 

 joint with a small conical tuft of hairs in the middle, next the face. Antenucs, short, scarcely half 

 the length of the forewing, slender ; joints indistinct, not annulated, with pale scales ; termi- 

 nated by a rather long gradually-formed club, formed of very short joints, obtuse at the tip, 

 which is curved outwards. Thorax, rather small, woolly in front. Ahdotnen, very slender. 

 Forewing, of moderate size, subtriangular ; the costa moderately arched ; apex rather rounded • 

 outer margin about two-thirds of the length of the costa, convex, very slightly scalloped ; 

 inner margin nearly straight, rather longer than the outer. Costal tierviire dilated at the 

 base ; subcostal with the first and second branches arising before the anterior extremity of the 

 discoidal cell ; third and fourth beyond it, at considerable distances apart. Upper disco- 

 cellular nervule very short, oblique ; iniddle disco-cellular considerably longer, less oblique, 

 slightly curved ; ^Z6^r disco-cellular much longer, transverse, the lower extremity curved J 

 little outwards ; uniting with the median nervure at the origin of the third median nervule 

 andclosmgthe^«mVa/^^// at two-fifths of the length of the wing. Hindwxng subtrian' 

 gularly ovate ; outer margin scalloped ; inner margin forming only a slight gutter for the 

 reception of the abdomen ; prcBcostal nervure curved, lightly furcate at the tip ; costal nervure 

 extendmg to the outer angle of the wing ; subcostal nervure branching at a moderate distance from 

 the base, followed quite closely by the upper disco-cellular nei-uule, which forms the slightly curved 

 base of the discoidal nervule ; lower disco-cellular very slender, strongly arched, uniting with 

 the median nervure at a little distance in advance of the origin of its third branch, and closing 

 the discoidal cell at about one-third of the length of the wing. Forelegs,' of the male 

 very small, slender, and delicate, very slightly and finely hirsute ; the femur rather longer than 

 the tibia ; tarsus rather more than half the length of the tibia, quite simple, and destitute of 

 articulations and claws, or terminal spines. Forelegs of the female half as long again as 

 those of the male, slender, scaly, and destitute of hairs ; the proportions of the different parts 

 as in the male, the tarsal portion as thick as the tibia, slightly dilated towards the tip, and 

 armed with three pairs of short spines, indicating the second, t hird, and fourth articulations.
