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. As it was I secured examples of several 
new species, Papilio bridget being among them. The most plentiful 
were a Precis near P. ada, but very differeut ‘to the Ugi form, 
Hypolimnas alimena, very fine, and several species of Zuplea. Danais 
archippus 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 little 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, 0D. gen. 
Head moderately large, hairy between the eyes; eyes rather 
prominent, smooth ; antenne 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 sinuate ; inner margin slightly 
grooved. First pair of legs imperfect, rather pubescent, pale green ; 
second and third pairs long, slender, smooth. 
This interesting genus does not appear to come very near any 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 surface. They were 
rather restless, and generally walked several times round the margin 
of the leaf, and then flitted off to the next. While so engaged their 
wings were kept erect, and the bright metallic spots and stripes made 
them very conspicuous.
