A. argenticeps sp. nov. (49 g) resembles a small dark lilacina, but the frons is lustrous lead-coloured, 
the collar is yellowish-red, the distal line slightly curved and indistinctly double. Sikkim and Assam. Type 
in the Tring Museum, also in the British Museum. 
A. bicostata Hmps. (49 g) (as bicolorata). Costal margin near the base slightly projecting, distal 
margin concave; forewing purely sandy grey, the lines yellowish-reddish orange, proceeding from black costal- 
marginal spots, the proximal line vertical, the distal line angular towards the apex, in the angle a black spot; 
the. light subterminal line marked with dark spots. Hindwing light yellow, along the hind-margin slightly 
discokmred. Khasia Hills. 
A. vira Mr. ( = erpina Swh.) (49 g as vera). Forewing lilac green with a lustrous reflection; the 
lines dark brown, proceeding from dark brown costal marginal triangles; the proximal line straight and almost 
vertical, the distal line strongly distally angled below the subcostal with an acute angle towards the apex, then 
straight and oblicjuely inwards. Subterminal line whitish. Fringes deep brown; at the upper end of the disco- 
cellular a small white spot and 3 at its lower end, one at the cell-end and 2 behind it. Hindwing: costal-marginal 
half whitish, turning pearl-grey towards the hind-margin, with traces of the line. Face dark brown, collar 
yellowish reddish. Khasia Hills (Assam). 
A. mimetica sp. nov. (49 g) resembles lilacina (49 h and Vol. II pi. ,48 d), but the discocellular is not 
marked with an angular line, but it exhibits 1 small white dot at the upper and 3 at the lower end, as in 
vira Mr.; the distal line is not quite straight, but erect from the hind-margin to vein 2, then oblique, the 
light subterminal line quite feeble. Hindwing as in vira ; base of fringes dark, apically lighter. Khasia Hills. 
A. humerata Warr. (49 g). Forewing greyish fawn-coloured; costal margin as far as behind the centre 
yellowish-reddish, behind it broadly rust-coloured; lines fine, rusty yellow, proceeding from oblique costal- 
marginal streaks, and distally acute-angular below the costal margin, the proximal line vertical, the distal 
line crooked in the centre; subterminal line of small crescents which are filled with black, behind the one at 
the apex a bright white spot; fringes rusty yellow; at the upper end of the discocellular a black spot and a 
heap of small black dots around a grey place at the lower end, which is often marked with whitish. Hind¬ 
wing with a light costal area which is broader in the $; a distal curved dark line does not extend beyond the 
centre. Under surface with a dull yellowish reflection, in the forewing more or less coated with greyish. Besides 
yellowish reddish, vertex metallic black. A small species; separated by the costa of the forewing being very 
convex at the base. Khasia Hills (Assam). 
34. Genus : Clallidrcpana Fldr. 
Separated from Albara with which it corresponds in the neuration by the antennae being bipectinnate 
in both sexes (in the $ longer). Type: C. argenteola Mr. 
C. argenteola Mr. (= saucia Fldr., scintillata Wkr.) (49 i and Vol. II pi. 30 f). Forewing light ochreous, 
strewn with small silvery scales, forming lines along and below the costal margin, as well as behind the distal 
brown line which extends near the distal margin; an oblique double brownish black cellular mark, often accom¬ 
panied by small silvery scales. — In ab. metaleuca B.-Bak. (49 i), from New Guinea, the forewing, particularly 
in the central area, is suffused with a pale brown. This is chiefly an insular species. Moore’s type of argenteola 
was from Java; Felder’s saucia from Amboina; Walker’s scintillata from Ceram; also from Sula Mangoli. 
Suer, Mefor, Kiriwini, the Fergusson Islands; Goodenough Is., Key Is., St. Aignan, Ron, Rock Is.; New r Guinea, 
Salomons, and Queensland. — The form occurring in the Salomons is a subspecies, argentifera Drc. (49 i) in 
which the under surface of both wings is marked with a distinct black thick distal line, whereas in the typical 
form this line is brownish and dull, mostly only recognisable towards the costa of the fore wing. — Another 
form occurs in some (may be all) of the Salomons, which may be separated as ab. subfasciata ab. nov. (49 i) in 
which the black line of the hindwing is sometimes expanded into a broad subterminal band, in others it forms 
a complete black marginal band; but this formation seems only to occur in the which are also darker 
on the forewing above. The $$ presumably never differ from the typical form. In some districts of New Guinea, 
on the Kumasi, Oetakwa, and Setakwa River the predominant form is grey powdered with ochreous, instead 
of the purely pale ochreous typical form which otherwise flies in the island; here the $$ are neither different. 
C. bracteata Hmps. (49 k). Forewing pale or brownish ochreous; the proximal line extends obliquely 
distally to the median, then vertically, feebly undulated, this lower portion only visible in browner specimens; 
the reniform spot is a deep brown oblique line, often double; distal line double, its distal portion thick, brown, 
on vein 6 angular before the apex, then oblique, between its two portions a feeble greenish tint. Before the 
distal margin small feeble dark spots; fringes in the upper half dark brown. In the hindwing the double line
