346 MR. G. F. MATHEW ON NEW [June 29, 



weak for much exertion. My hunting-ground was therefore confined 

 to a slope on the hillside at the back of the native village, which 

 had recently been cleared for yam-planting. Here Butterflies were 

 more numerous than at Ugi ; and if the weather had been more 

 favourable, and I had been able to get about more, I believe I should 

 have taken a large number, xis it was I secured examples of several 

 new species, Papilio bridgei being among them. The most plentiful 

 were a Precis near P. aria, but very different to tlie Ugi form, 

 Hypolininas aJimena, very fine, and several species ofEuplcea. Danais 

 arcJiippus was not seen at all in this place, although it was so common 

 at Ugi ; perhaps its migration had not yet extended so far in a north- 

 westerly direction. 



From the httle I have seen of the Solomon Islands, I feel quite 

 convinced that when they are properly worked they will yield a large 

 number of new and interesting Rhopalocera, and I hope on a future 

 occasion to be able to describe some more new species. 



Argyronympha, n. gen. 



Head moderately large, hairy between the eyes ; eyes rather 

 prominent, smooth ; antennae long, slender, extending to beyond two 

 thirds of costa, with a long, gradually-thickened club : palpi 

 conspicuous, pea-green, porrect, ascendant, clothed outwardly at their 

 base with fine short white hairs, the hairs less numerous towards the 

 tip and dark grey; tip black, finely pointed: thorax rather short: 

 abdomen almost as long as hind wings, slender, pinched in at base, 

 and with a brush-like tuft of hairs at base of genital organs in male. 

 Fore wings rather long and narrow in male, broader in female ; costa 

 moderately arched, convex at base ; apex somewhat acute in male, 

 truncated in female ; hind margin entire, oblique ; inner margin 

 straight, hairy to beyond the middle ; anal angle slightly obtuse ; 

 nervures of fore wings dilated at base ; cell narrow, rather long ; first 

 subcostal nervule emitted just before end of cell ; discocellular 

 nervules pointing outwards ; median nervure and first discocellular 

 nervule forming a moderately acute angle. Hind wings : costa 

 elbowed at base, very slightly concave at one third, and rounded off 

 at apex ; hind margin very moderately sin\iate ; inner margin slightly 

 grooved. First pair of hgs imperfect, rather pubescent, pale green ; 

 second and third pairs long, slender, smooth. 



This interesting genus does not appear to come very near an}- yet 

 described, but bears some relationship to Hypocysta, Westw., and 

 Nissanga, Moore. 



These beautiful little Butterflies were local in their habits and of 

 retiring disposition, frequenting shady spots in the dense forest. 

 "When disturbed, they flew but a short distance and settled upon the 

 leaf of some low shrub, always on its upper sur/'ace. They were 

 rather restless, and generally walked several times round the margin 

 of the leaf, and then flitted off to the next. While so engnged their 

 wings were kept erect, and the bright metallic spots and stripes made 

 them very conspicuous.
