the 4th and 5th of which are larger and united with the discal band by rays; the hindwing white with 8 black 
marginal spots. Body and size almost of arctata. Formosa, at an altitude of 7000 ft. 
D. carissima Swinh. (26 i) often flies together with arctata ; in Sikkim and Assam, the Kliasia and 
Naga Hills. At once discernible from arctata by the quadrangular, white subapical spot of the forewing and by 
the abdominal dorsum not being banded black, but spotted in pairs. Pagenstecher simply places the species 
to mulleri of which there are specimens before me with a s p o 11 e d and a transversely striped abdomen (from 
North East Borneo, thus from the same district). As Swinhoe himself, after having described the brown and 
white marking of the wings, adds that ,,the spots of the forewing and the marginal band of the hindwing vary“, 
a separation is in fact scarcely differently to be carried out than according to the origin. 
D. formosana Swinh. In the forewing, with drab markings, the discal band is connected with the 
margin by a band, and this longitudinal band encloses a large dark spot. Before the apex a white spot; the 
marginal band of the hindwing is drab, pierced. Formosa. Not lying before me. 
Appendix. 
We add here two lepidoptera that have wrongly been placed with the Arctiids. Both have an isolated 
position, and one of them has from cogent reasons been regarded as the sole representative of a separate family 
of lepidoptera. Both were described from Himalayan valleys, exhibiting a blackish body being in front and 
behind orange-red, and black wings spotted white. They are common, and so characteristic that we may refer 
to the figures with respect to its characterization. The two lepidoptera have nothing whatever to do with each 
other. The first, Macrobrochis gigas shows relations to certain microlepidoptera, whilst the second exhibits 
only a very slight alliance to some Callidulids, though much too little as to justify its insertion there. As to 
the habits and particularly the larvae of both species nothing has become known. 
Genus: Macrobrochis. 
This genus of which only one species is known *), is found in the most ancient catalogues in the Litho- 
siinae to which it shows a superficial resemblance in the habitus. The slender body, broad head, long forewings 
and large hindwings, which are very much folded when at rest, are indead common in the Lithosia. Hampsox 
in his Fauna of India (Moths II, p. 66) figures also the veins of which ,,vein 8“ is absent on the hindwing, so 
that the species would in fact belong to the Lithosiidae. But in the 14 specimens of my collection I do 
not discover this kind of venation in any of them. Vein 8, however, comes from the base of the hindwing, running 
for some distance along beside the base of the subcostal and only then anastomoses with it. We nevertheless 
insert the species here referring to this behaviour, because it has been dealt with in Kirby’s Catalogue, in the 
special works on India etc. in the Arctiids, and it will therefore be looked for here. 
Head moderately broad; eyes large, antennae in the $ with very fine, short cilia, palpi short, obliquely 
haired, legs short, middle tibiae with a pair of strong, stout end-spurs, posterior tibiae with middle-and end- 
spurs. Abdomen in the g slender, when at rest strongly bent up, in the $ stout. Forewing long-extended with 
a pointed apex and oblique border, completely margined, with short fringes, the proximal margin very slightly 
curved. The 1st subcostal vein anastomoses with the costal, the 2nd with the footstalk of the other branches. 
The cell is long, the discocellular angled. On the broad hindwing the lower radial rises with the upper median 
vein from the lower cell-angle; the margin is slightly concave below the apex. 
M. gigas Wkr. (26 h). This common Himalayan species is distributed across the whole eastern part 
of the mountain-range, from Sikkim to Assam. Black, anterior part of the thorax, body beneath and abdominal 
end orange. Forewing blackish-blue metallic with 3 large white spots in the proximal half and 4 to 7 in the 
distal half of the wing. Hindwing proximally white, distally black. — The spots vary a great deal. In ab. 
interstitialis H.-Schaff. the spots are slightly enlarged, and below the cell of the forewing appears besides 
a white, longitudinal diffuse spot; — in leucospilota Moore the black of the hindwing is much narrower. — ab. 
albicans Btlr. (26 i) has the hindwing nearly all white and also the spots of the forewing much larger. — ab. 
nigrescens Moore (26 i), on the contrary, has the spots of the forewing very much reduced, — and in ab. atrata 
Btlr. (26 i) they have disappeared altogether except faint traces. All the aberrations occur beside each other 
in the same district. They are common, flying in day-time only when they are beaten from the branches hanging 
across the road or from the brushwood; the larva is unknown. 
* Other species recconed hereto are in fact Lithosiids.
