8. Hypolimnas errabunda, sp. n. 



Male (PL II, fig. 5). Upperside very dark brown, apical third of fore- 

 wing and a broad terminal border strongly suffused with red-brown ; a series 

 of three very small preapical white dots in interspaces 5-7 ; hindwing with a 

 broad ochreous-brown sub-terminal border. Underside brown, apical third 

 of f orewing and a very broad postdiscal band on hindwing paler ; preapical 

 white dots larger than on upperside, and continued as a postdiscal series of 

 dark-ringed bluish-white spots on both wings ; sub-terminal and terminal 

 narrow dark lines ; in cell of forewing a triangular white spot, followed by three 

 rather irregular white lines. Cilia white, alternated with black. 



Female (PI. II, fig. 6) similar, but paler ; on upperside preapical dots much 

 larger than in male, and continued as a postdiscal series of white spots in all 

 the interspaces of forewing, and very faintly in interspaces 5-7 of hindwing ; 

 on underside markings as in male, but postdiscal white spots much larger and 

 not bluish. Cilia as in male. 



Type male from Malololelei, Upolu Island, 2,000 feet, 27.iv.24, allotype 

 female from same locality 4.V.24 ; 9 male and 4 female paratypes from same 

 locality, various dates. Maximum, mean and minimum expanse of males (exclud- 

 ing two bred specimens) 77, 72, and 66 mm., of females 92, 87, and 82 mm. 



Variation is very slight ; in the male the postdiscal series of white dots 

 is sometimes very faintly developed on the upperside in some of the interspaces 

 of both wings, and there is slight variation in the width of the ochreous-brown 

 subterminal border of the hindwing, and in the development of the red-brown 

 suffusion of the forewing ; in the female the spots in interspaces 2 and 3 of the 

 hindwing upperside (never very distinct) are sometimes almost obsolete. The 

 underside is almost invariable in both sexes. 



An uncommon species and never seen below 2,000 feet, although the food- 

 plant occurs down to 1,000 feet and probably below. Only found in Upolu 

 Island at Malololelei, Lake Lanuto'o, and probably other localities at high 

 elevations, though the food-plant is common in Tutuila. Both sexes frequent 

 the flowers of Lantana. The colour and markings give this insect a distinct 

 resemblance to Euploea schmeltzi, but the female is very much too large to be 

 mistaken for that species. In the male, however, owing to its much smaller 

 size, the resemblance is much greater, and it is quite possible to mistake one 

 species for the other on the wing. Odd specimens (sometimes only one) were
