SIDERIDIS. By W. Warren. 
pale, finely lined with dark, the terminal intervals also with dark streaks; the median nervure and veins 3 and 4 
more prominently whitish; a dark streak on each side of median vein, continued above vein 4 to termen, 
where it is widened; outer line indicated by black points on veins 6, 5, 3, 2; hindwing pale ochreous with 
mediofusca. rufous tinge; dark outer points on veins 6, 4, 3, 2; in the ab. mediofusca limps. (12 f) from the Nilgiris, the 
median streak and the other dark shades are more fuscous, and the hindwing is paler without points; in ab. 
roseata. roseata ab. nov. (12 g) dark streaks are replaced by pale rosy brown along cell and above inner margin. Occurs 
only in Ceylon and S. India. The species is characterised by the presence of a bed of hair and scales along 
vein 1 on the underside of the fore wing of the <$. 
gonio- S. goniosigma limps. (12 g). Forewing pale ochreous; a streak of mixed reddish and black scales 
sigma. a l 0 ng and above median vein from base of cell to outer line; a black dot at base of costa; inner line interrupted, 
marked by slight black lines at each extremity; outer line a double row of black vein points, the outer of the 
two joined at vein 4 by a dark oblique shade from below apex; interspaces of terminal area with brownish 
streaks; the veins whitish; small black terminal lunules; fringe chequered black and Avhite; at end of cell a 
prominent white rectangular mark on median vein, containing a black dot; hindwing fuscous, with the base 
and inner margin ochreous; the fringe ochreous. Described from a single $ from Ceylon. 
dharma. S. dharma Moore (= rufescens Moore) (12 g). Forewing ochreous suffused with rufous, and dusted 
with blackish along costa and inner margin; streaks of terminal intervals rufous, and the pale veins lined 
with rufous; inner line marked by black dots, oblique; outer line strongly lunulate dentate, the teeth forming 
prominent black marks on veins, met at vein 4 by an oblique dark shade from termen; median vein fuscous, 
only the extremity white, and slightly hooked on discocellular, with a black dot before it and a small blackish 
patch beyond it; veins 3 and 4 whitish; hindwing ochreous, suffused with fuscous except at base and along 
costa; fringe ochreous. Found in the Punjab and Sikkim, N. India, and in the Andaman Islands-. 
rufisirigosa. S. rufistrigosa Moore (12 g). Forewing ochreous, with the cell and area just below and beyond it bright 
rufous, produced obliquely to apex; costa and inner margin dusted with blackish; nervules defined by rufous 
and the intervals streaked with rufous; inner line formed by oblique dark dots on costa, median vein, and sub- 
median fold, and one nearer base on vein 1; outer by a curved row of dark dots, joined by an oblique dark 
shade from apex; median vein fuscous, its extremity only whitish, slightly hooked on discocellular, and followed 
by a small fuscous patch, with no black dot before it; hindwing ochreous with fuscous irroration; the fringe 
ochreous. Found at Dharmsala and Umballa in the Punjab, and in the Nilgiri Hills, Madras. Probably a form of 
the preceding, with the end of the median vein more lengthily white. 
ignita. S. ignita Hmps. (12 g) d'. Forewing orange yellow, suffused throughout with purple red, the ground 
colour appearing only along inner margin and terminal area, in the end of cell, and at base below cell; costal 
area white dusted with black, suffused below with greyish fuscous; median vein greyish fuscous, the extremity 
only white; a patch of same colour beyond cell between veins 3 and 5; inner line an oblique row of vein 
points angled on submedian fold; outer line a curved row of points, joined at vein 4 by an oblique dark 
shade from apex; veins of terminal area pale; hindwing ochreous suffused with dark, the termen tinged with 
pink; the fringe ochreous; the $ night easily be mistaken for a distinct insect, so different is its coloration; 
pale ochreous and pale grey brown taking the^place of the orange yellow and dull red of the <$. Khasia 
Hills, Assam, N. India. 
formosana. S. formosatia Btlr. (= adusta Moore) (12 h). Forewing ochreous, with sparse dark irroration and parti¬ 
ally suffused with fleshcolour; the streaks of terminal intervals and on each side of the veins fuscous; inner line 
marked by black points oblique to submedian fold, then angled to vein 1; outer line obscurely lunulate dentate, 
the teeth distinctly black; an oblique dark shade from apex; orbicular and reniform stigmata ochreous, very 
obscure, the reniform with a black dot in lower part and a short yellow streak below it at end of median vein; 
hindwing whitish, the veins and terminal half brownish; its underside with costal and terminal borders tinged 
with purplish pink and dusted with black; an outer row of short black vein dashes and black terminal 
semicana. points below apex; the form semicana Pag. (12 h) is strongly marked, with the end of the median vein white. 
A widely spread species recorded from the Punjab, Sikkim, and Assam in N. India, and from Travancore 
in the South; Ceylon; Formosa; Selangor; Borneo; the Bismarck Archipelago, whence the type of semicana. 
Pag. ; the Solomon Ids; the Louisiades; Trobriand Islands; New Guinea; and Queensland; in the form from 
confcrta. Queensland, - — subsp. conferta subsplnov. (12 h), the rufous tints are obsolescent and the $$ are thickly 
powdered and striated with grey.
