which reaches vertex, is triangularly scaled in front; the third, as long as the second, is slender and 
smoothly scaled, but with two slight scale tufts above, at base and near tip. Type D. nigro'punctata Beth- 
BaJcer. 
D. albolineata Beth.-Baker (23 f). Forewing bright brown red; the base grey with a white line close albolineala. 
to base and bounded by a curved white line with a row of brown points on it, emitting a white streak through 
upper part of cell, which typically branches off into three streaks beyond upper angle, where there is a small 
white lunule; outer line white, with a row of dark dots on its inner edge, bent outwards below costa and ex- 
curved between vein 8 and 6, where there are two small wedge-shaped black marks before it, then incurved, 
again excurved between veins 5 and 3, incurved on submedian fold, and excurved to inner margin; subter¬ 
minal line crenulate, incurved and white edged outwardly with blackish from costa to vein 4, then slightly 
oblique and incurved in submeclian interval; terminal area with white patches at apex and between veins 
6 and 4 with a black patch between them and some slight yellow marks beyond subterminal line; some black 
and white points just before termen; fringe with white points at base and white streaks between veins 6 and 4; 
hindwing bright brown red, the terminal area browner; inner margin fringed with white hair; an oblique white 
line at base; cellspot black; the rest as in forewing; ab. subrubra ab. nov. (23 f) has the ground colour subrubm. 
of both wings dull brick red; all the white markings of forewing absent, except veins 6, 7 (which are both 
quite narrowly pale) and the long white crescent before the apical blotch; the basal area dull greyish; 
another ab. lichenosa ab. nov. (23 f) has the basal area of both wings, the metathorax, and the apical blotch lichenosa. 
of forewing, leaden grey, this last with a narrow black patch at middle; the orbicular dot and the 
lunulate reniform snow white; the lines remaining the same in all cases. Aroa River, British Yew Guinea. 
D. nigropunctata Beth.-Baker (23 f). Forewing yellowish tinged with rufous, slightly irrorated and suf- nigropunc- 
fusecl with brown; subbasal and inner lines curved, brownish, punctiform; cellspot large, black, often defined iata - 
by black points; a dark median line, excurved in cell; outer line punctiform, excurved above, then oblique 
inwards, followed by a dentate dark shade from below costa to inner margin; subterminal yellowish, angled 
outwards at 7, dentate and oblique from 5 to inner margin; apical area yellowish; a row of black dots just 
before termen; hindwing yellowish tinged with rufous and irrorated with brown; inner line brownish; 
cellspot double, black; the other lines much as in forewing. Aroa River, British Yew Guinea; Renclova, 
Solomon Islands. Like so many other Yew Guinea species this insect is very variable; the form described 
above, though typical, is by no means the commonest, which is uniformly grey without any yellow 
ochreous admixture, and may be distinguished as ab. uniformis ab. nov. (23f); this is the usual form in the $$ uniformis. 
and many <$<3 ; — theab. semistriganh nov. (23f) occurring, as far as I have seen, only in the has the costal semistriga. 
half of subterminal line pure white; — ab. albifusa ab. nov. (23 f) — a single $ only — has the space beyond albifusa. 
this white striga to termen whitish, and the area beyond median line of hindwing also thickly powdered with 
white, the black subterminal dots being preceded by white wedge shaped markings, as in the apical blotch of 
forewing. 
D. mediopallerjs Beth.-Baker (23 g). Forewing grey brown; basal area with patches of deep red, mediopal- 
a large patch on inner marginal area beyond middle, and a diffuse patch from beyond end of cell to termen lens - 
from below apex to vein 3; two black dots at base; inner line crenulate, limiting the red area; a crenu¬ 
late median line; a round cell spot defined by black points; outer line blackish at costa, then red, bent 
outwards below costa, excurved to vein 4, then incurved and outwardly oblique to inner margin; subterminal 
line white, incurved from costa to vein 4, toothed on veins 7 and 5, then ill-defined and oblique; hindwing 
grey brown; the inner margin white; slight black points at angles of cell; the rest as in forewing; a remarkable 
form of this species — ab. fulvinigra ab. nov. (23 g) has the ground colour bright fulvous yellow, the basal fulvinigra. 
area and space just beyond it and a large triangular apical blotch, including the usual apical patch, all smoky 
blackish; the hindwing Avith basal patch and anal quarter blackish, the rest of wing pale fulvous. The 
lines in the forms of this species and those of albilineata are precisely the same, and I cannot help thinking 
that they will prove to be one species, though the material at present available for comparison is too slight 
to enable one to speak with certainty. Aroa River, British Yew Guinea. 
D. biarmioides Walk. (23 g). Forewing ochreous tinged with reddish brown and irrorated with fuscous; biarmioides. 
a double dark but ill defined snbbasalpine from costa to inner margin; inner line dark, double at costa, oblique 
to middle of cell, then erect, with a slight black mark before it in cell; a small oval cellspot outlined 
with blackish; outer line indistinctly double, the outer arm diffuse, oblique from costa to vein 4, then slightly 
waved; a diffuse dark subterminal shade from costa to vein 4; some black dots just before termen; hind¬ 
wing with terminal area suffused with dark brown; two oblique black discoidal striae; an oblique dark line from
