20 NYMPHALID/E. NYMPHALIN^. EURIPUS. 



spots round except the fust six (which have the form of linear streaks), and the last (which is 

 elongJterancl arranged two in each interspace except the eighth from the apex (m wh.ch 

 there are three), and the last, in which there is only one. Hind-wiug uniformly coloured, w.th 

 a d sc-rl series of seven violet-white spots and dots, arranged in two series, an mterjor curved 

 one oft le and a posterior straight one of four, the three foremost of winch latter. wUh 

 the last of the anterior series, coincide with the four impressed spots of the upperside ; 

 and with a submarginal series of spots of the same colour, situation, and extent as in he 

 forewing but differing somewhat in shape, the last three being linear streaks parallel to the 

 outer margin, and the rest more or less elongate, and those of each pair divergent externally 

 as if they were the remaining outer ends or horns of lost lunules." (Wood-Mason, I.e.) 



This form is also variable; on the upperside of the forewing in £. «,'././/«. described 

 from Sylhet there is a distinct submarginal series of pale streaks placed in pairs between the 

 nervules, and two pale suffused discal spots in the lower median and submedian inter- 

 spaces, which are not present in E. cinnamomeiis, the hindwing in E. nyctelms is also much 



paler outwardly. 



Female III Form. Upperside. foreiving hair-brown, the outer margm towards the 

 anal angle very slightly paler, and showing just the faintest trace of the discal band from the 

 costa which is present in E. isa, the marginal dots and streaks present, but hardly visible. 

 Hindioing hair-brown, a discal series of whitish spots between the veins, the four upper ones round 

 and equal-sized, the fifth in the second median interspace larger and diffused inwardly, the one 

 in the space below elongated into a streak, the one in the submedian interspace still longer 

 and bifurcated outwardly, some obscure streaks on the abdominal margin above the anal 

 an"-le. The usual whitish spots in pairs on the margin. Underside, both wings paler, the 

 inner margin of the forewing pale purple, the marginal streaks and spots more distinct than 

 above. Hindwing with a discal series of even round whitish spots, somewhat blurred at the 

 anal angle, marginal spots as above. 



The sin<Tle specimen described above, which is in Major Marshall's collection, was taken 

 in the Thoungyeen Forests in Upper Tenasserim in April by Captain C. T. Bingham, and 

 apparently mimics Euplcea akathoe, which occurs with it. As the other female forms have been 

 named I propose for the sake of convenience to call this one E. alcathoSoides. 



This species with both female forms isa and cinnamomeiis occurs in Sikkim, there are 

 males in the Indian Museum, Calcutta, from Sylhet. Cachar ( Wood-Mason) ; Naga Hills ; 

 Sibsagar ('5. ^. /'c-rt/^ ; Mr. Sherwill has taken ^. /ja at Jorehat. Assam, in June; Shillong 

 (also type oi E. cinnamoineus), and Upper Burma (taken by the Yunan Expedition). Mr. 

 E. F. T. Atkinson records it from the outer ranges of the Himalayas of the North- Western 

 Provinces. 



The fi<Ture shows the upperside of a male and a female I. Form, both from Shillong, in the 

 Indian Museum, Calcutta. 



A very slight variety of E. halitherses has been described from the Malay peninsula 

 under the name of E. euplceoides. The male appears to differ from the Indian form only in 

 having three or four marginal dots only at the anal angle of the forewing on both sides, in the 

 Indian species these dots usually extend as far as the third median nervule. The ground-colour 

 of the female is even paler than the first female from Shillong described above under the name 

 E. isa, though the white portion of the hindwing is less extended in the Malayan form. 

 The description is appended.*
