life-histories of new species of Rhopalocera. 313 



of indistinct pale lunules, the one preceding that at anal angle of 

 secondaries sometimes having a black spot in its centre. Fringes 

 pale grey. Exp. 22 to 24 mm. 



This little butterfly was very common at Tongatabu, 

 and it also occurred at Fiji, Samoa, and the New 

 Hebrides ; and I have a worn specimen from Cooktown, 

 Queensland, which I believe is referable to the same 

 species. 



I obtained the first larvte by beating. The butterflies 

 were very local, and only to be found in the neighbour- 

 hood of certain papilionaceous shrubs. I afterwards 

 discovered that the larv£e were easy to find by simply 

 examining the clusters of flower-buds at the extremity 

 of a branch, for wherever there was a larva, there were 

 sure to be half-a-dozen or more red ants crawling over 

 it, and thus betraying its position. Moreover, the larvae 

 took no pains to conceal themselves, but fed quite 

 exposed among the buds. They were also accompanied 

 by numbers of small black aphides. 



The full-grown larva is from 12 to 14 mm. long, 

 onisciform, not much thickened in the middle, but almost 

 of uniform stoutness throughout, is slightly pubescent, 

 and has a few short scattered bristles ; head very small, 

 retractile, pinkish brown, with a dark V-shaped mark on 

 face and black ocelli ; segmental divisions finely though 

 clearly defined ; the colour varies from pale pea-green 

 to a warm pinkish green; a conspicuous purple dorsal 

 stripe bordered on each segment by crescent- shaped 

 purple marks, which are broadly margined below with 

 whitish yellow, forming a pattern down the back ; 

 spiracular line pale yellowish pink, bordered above and 

 below with purple ; space between the dorsal and 

 spiracular lines slashed with short obscure purple 

 stripes ; ventral area and claspers paler ; whole surface 

 more or less irrorated with minute black and white 

 dots, scarcely visible to the naked eye ; legs very small, 

 pale pinkish green. Upon each side of the anterior 

 part of the thirteenth segment, a little above the 

 spiracular line, there is a small whitish tubercle, from 

 which the larva can at pleasure emit a short fleshy 

 tentacle, which is crowned at its summit by a fascicle, 

 or whorl, of fine white bristles. The larvae would not 

 protrude this organ when they were breathed upon, 

 touched, or otherwise annoyed, but only occasionally as
