658 SARONAGA; HABROSYNE; THYATIRA. By M. Gaede. 
1. Genus: Saronaga Mr. 
Palpi hairy on the first two joints, the third short. Antennae of finely ciliated. Patagia densely 
haired. Forewing oblong. Vein 5 above the centre of the cross-vein, 6 from + 3 of the length of the ac¬ 
cessory cell, 7 and 8 + 9 from its apex, 10 a little before the apex. On the hindwing vein 5 not far off 
from vein 4. 
S. albicosta Mr. (85 a). Thorax and forewing dark red-brown, costal margin broadly brightened by 
white. Transverse line notched, rather indistinct. Hindwing lighter, with a broad dark margin. 55—58 mm. 
Darjeeling, Bengal. — commifera Wan., already treated upon in Vol. II, p. 322 and pi. 55 m, chiefly differs 
only in the reddened costal margin of the forewing. Punjab, also in China. 
2. Genus: Habrosyne Hbn. 
Antennae of $ slightly flattened, scarcely ciliated. Palpi thickly haired on the two first joints. Ab¬ 
domen with lateral hair-tufts at the end. Fore wing with a hair-pencil at the anal angle, the inner margin 
curved, veins 7+8 from the apex of the accessory cell, 9 and 10 from its anterior margin. Vein 5 in both 
wings arises on the centre of the cross-vein. Type: derasa L. from Europe. 
H. derasa L. which has been dealt with in Vol. II, p. 323 and pi. 49 d and 55 n occurs in our district 
in two forms: derasoides Btlr. (= fraterna Mr.) (Vol. II, pi. 55 m), from Dharmsala; judging from the original 
figure it merely differs from derasa in showing somewhat more white below the costal margin of the forewing. 
indica Mr. which has also been treated upon in Vol. II (pi. 55 n), is larger and the strongly undulated 
lines in the distal area are less distinct. 42—48 mm. Sikkim. 
H. armata Mr. (85 a). The white oblique line of the forewing is distinctly bent, the .undulate line 
at the inner margin finely white, less undulated anteriorly than derasa., 40 mm. Khasia Hills. 
H. plagiosa Mr. (85 a). Ground-colour considerably browner. The two light lines broadly faded in¬ 
wards, somewhat pink. Interior line much steeper than in indica and armata, the line from the apex to the 
anal angle uniformly bent. 45—50 mm. Sikkim. 
H. sanguinea Mr. (85 a) differs considerably in the rusty red and rusty brown colour. The distinct 
interior line is incurved at the inner margin. One piece each of the exterior line is yet present before the 
undulate line at the costal and inner margins. 40—42 mm. Sikkim. 
H. argeoteipimcta Hmps. (85 a) is the most similar to sanguinea. Thorax and forewing greyish-brown, 
the broad median area blackish-brown, except at the upper angle. The white silvery spot is distinct at the 
base. The interior border of the median area is uniformly curved from % costal margin to % inner margin. 
Reniform macula of the ground-colour, finely edged with white, with a violet blotch towards the base. Ex¬ 
terior line from vein 2 to the inner margin somewhat distally with a distinct fine yellow colour. The undulate 
lines above it fine bluish-grey, much less undulated than in sanguinea. The marginal area between veins 2 
and 4 darker than the rest, with a faded bluish-grey band, instead of the light line of sanguinea. The light 
arcuate line at the margin is quite obsolete. Hindwing reddish-brown. Vein 5 farther in front than in san¬ 
guinea. $ 38 mm. Htawgaw, Upper Burma. Type in the British Museum. 
H. undularis Hmps. Described as Thyatira, but judging from the sketch it belongs to this genus here. 
Thorax reddish-brown. Forewing with a black line from the base of the costal margin in a bend to behind 
the centre of the inner margin, then upwards to the costal margin near the apex. Before this line brown with 
a pinkish-white triangle at the costal margin. Below the line a white spot from the base to the centre of 
the wing, the rest of the interior area also brown. Distal area pinkish-white with an indistinct undulate sub¬ 
marginal line, faded brown behind it and blackish above vein 2. Hindwing whitish with a dark median line 
and margin. $ 38 mm. Khasia Hills. 
3. Genus: Thyatirsi Hbn. 
Palpi porrect, the third joint long, projecting beyond the frons. Antennae of G finely ciliated. Thorax 
densely haired. Vein 5 of forewing below the centre of the cross-vein, 6 from the base of the accessory 
cell, 7 and 8 + 9 from its apex, 10 arising before the apex. Vein 5 of hindwing likewise below the centre 
of the cross-vein. Type: batis L. from Europe. 
Til. labiata n. sp. (85 b) is between diminuta Houlb. and unipunctata Houlb. which were described from 
the palaearctic region after the publication of Vol. II. The light lobe at the base of the forewing is short. 
A spot before the centre of the costal margin as in transitans Houlb. The apical spot is smaller than in 
diminuta. The indistinct light notched median and exterior lines are finely white at the inner margin. Hind¬ 
wing with a lighter median line and light fringe $ 48 mm. Upper Burma. Type in the British Museum.
