T. batis L. This species so very common in Europe and described in Vol. II, p. 323 also occurs in the batis. 
Himalaya in the scarcely different form cognata Mr. pi. 49 e, in which the spots are not so beautifully rosy 
red. — vicina Guen. has somewhat narrower spots at the base and anal angle. Java. vicina. 
T. decorata Mr. (85 a) is similar. The basal spot is divided into three smaller ones. A large spot decorata. 
in the centre of the cell and a small one at its end, both absent in batis. The costal-marginal spot at the 
apex is differently shaped, several small spots are at the margin. 40—42 mm. Sikkim. 
T. geminata sp. n. (85 b). The basal spot is not parted. The two spots in the centre of the cell are geminata. 
much larger, slightly fused. The interior apical spot is larger than the exterior one and fused with it. At 
the centre of the inner margin there is no spot. A series of indistinct spots before the distal margin, the lowest 
more distinct. 48 mm. Sumatra. Type in the Berlin Museum. 
T. arizana Wilem. is probably similar to oblonga Pouj. (Vol. II, p. 56 e). The 5 spots are ochreous arizana. 
brown. The basal spot is oblong, the spot at the centre of the inner margin somewhat double, the spot at 
the inner angle small, 44 mm. Formosa. 
T. sframineata Warr., from the Khasia Hills, has been dealt with in Vol. II, p. 324 and pi. 55 n. Beside siramineaia 
the basal spot it shows one more each at the centre of the costal margin and at the apex. 
T. trimacula Brem. The Japanese nomenclatural form does not occur in our district. — albomacu- trimacula. 
lata Leech has almost white spots. Hindwing paler with a distinct central spot and exterior line. 1 $ from albomaC j c ^ a 
Itchang. — chinensis Leech. The basal spot of the forewing is covered with a few black scales. Hindwing chinensis. 
dark, with a dark central spot and exterior line. 38—41 mm. Changyang. — formosarsa Mats. (85 b) is as formosana. 
large as chinensis. In spite of its size the distance between the basal spot and that at the inner angle is 
smaller than in trimacula. The light notched line before the distal margin is scarcely traceable. The colour 
of the 3 spots as in trimacula. Hindwing, however, not as in the latter, but as in chinensis. Formosa. 
Th. angulifera sp. n. (85 b) is quite differently marked. The light edge of the basal spot on the angulifera. 
forewing of the other species is only represented here by a pink spot at the costal margin, and a fine white 
angle is below the cell, besides the light streak of the Habrosyne- species near the base. Ground-colour dark 
nut-brown. Traces of about 4 dark undulate lines in the median area, being somewhat more distinct only at 
the lighter costal margin. The double black exterior undulate line is better noticeable, its distal branch is 
finely and distinctly edged outside with bluish-white. A yellowish-brown line from the anal angle vertically 
in front and another one to the apex, the space between them of the same colour, enclosing a very dark 
spot at the costal margin. Bluish-white streaks at the margin. Hindwing reddish-brown, fringe spotted lighter. 
The hair-pencil of the abdomen is longer and finer than in batis. <3 38 mm. Hpimaw, Upper Burma, 2500 m. 
Type in the British Museum. 
T. tenuis Hmps. has already been dealt with in Vol. II, p. 325, pi. 56 f, since it originates from the tenuis. 
palaearctic region, but it may also occur in Burma and is therefore mentioned here. 
4. Genus: Cymotrix gen. nov. 
Intermediary between Thyatira and Gaurena. Antennae of ciliated. First and second joints of 
palpus thickly haired, Veins 4 and 5 of forewing close together, 6 from the upper cell-angle, 7 + 8 and 
9 + 10 stalked or 8 and 9 anastomosing and forming an areola. A long hair-pencil beneath near the base 
at vein 1. Vein 5 of hindwing also very near to 4. Type: decora sp. nov. 
C. decora sp. n. (85 b). Forewing dark reddish-brown. The lighter interior line is straight, very obli- decora. 
quely distad to the submedian fold, then introangular. A black basal spot before it, 2 dark lines behind it. A 
black spot in the centre of the cell and at the cross-vein, with a broader bent dark line behind it. Exterior 
line treble, bent in the middle, a yellow spot outside at the inner margin, behind it 3 fine white marginal 
clots, and black dots above the latter. A lighter blotch at the apex. Hindwing grevish-brown. G 48 mm. 
Mt. Kunupi, 2000 m. (Dutch New Guinea.) Type in the British Museum. — indecora form. nov. Forewing indecora. 
very dark. Interior line and the two cellular spots still distinct, the spot at the inner margin smaller. Marginal 
clots present. From the same habitat. Type in the British Museum. 
C. submarginalis sp>. n. (85 c). Ground-colour as dark as in indecora. Interior line the same. A reddish submargi- 
light dot in the centre of the cell. Exterior line reddish, rather sharply reversed at vein 4, distinct. Margin 
narrow reddish-brown, bordered inside by a white line, with black spots before it. Hindwing somewhat lighter 
than in decora. $ 45 mm. Mt. Kunupi, 2000 m. (Dutch New Guinea.) Type in the British Museum. 
5. Genus: Cwaurena Wh\ 
Separated from Thyatira only by vein 6 also arising already from the areola. Type: florens Wkr.
