T, virescens Hamps. (81). Greenish black, the 4 th and 5 th rings of the abdomen yellow. Hindwings 
unicolorous; in the forewings four transparent spots, of which one is before the tip and three from the apex 
of cell to near the anal angle, the latter of these three very small. Ceylon, Southern India. 
15. Genus: (PI aty zygaena Swinh. 
?: Antennae simple. Palpi very small. Spurs short. Body heavily built. Wings rounded, broad; in 
the forewings the 3 rd and 4 th subcostals stalked, the 5 th arising close to the stalk, end of cell angled between 
the 1 st and 2 nd radial; in the hindwings the 1 st radial is present, all the veins arising from the cell. One 
North Indian species. 
P. moelleri Elw. (8 1). Body blue black, whith white rings. Wings black; forewings with grey veins 
a broad white band near to the base bears four white dots; hindwings from the border to the cell white. 
North India; Sikkim and Assam. 
16. Genus: Zygaena F. 
Antennae of the cY and ? strongly clubbed. Hind tibia with two pairs of spurs. Wings ample; the' 
3 rd and 4 th subcostals of the forewings with a long stalk; the subcostal of the hindwings seperated from the 
costal, running obliquely from the connecting vein (= 1 st subcostal) to the apex of cell, 1 st radial present 
Af phlaearctic <®enus, which is represented by one species on the border of the oriental region. 
Z. rubricollis Hamps. Pronotum and spots of the forewings red. Resembles Z. dorycnii. Chitral in 
the Britith Museum. 
17. Genus: Epizygaena gen. nov. 
A further clevelopement of Zygaena F. Rear tibia with one pair of spurs. The forewings with the 
2 nd —4 th subcostal nervures stalked. Northwest India; South Afghanistan. 
E. caschmirensis KoU. (Vol. 2, PI. 8 k). Forewings with five pale yellow spots. Hindwings red with 
generally two interrupted black transverse bands. The 5 th and 6 th abdominal rings or the 5 th to 7 th have broad 
red borders above. The ab. asoka Moore (Vol. 2, PI. 8 k) has more extensive black on the hindwings 
Afghanistan to Nepal. 
E. erythrosoma Hamps. (81). As before, but the prothorax without the yellow lateral spots. Kumaon; 
in the British Museum. 
E. afghana Moore (Vol. 2, PI. 8 f). Pronotum and abdomen red; spots on the forewings red, with 
white border; hindwings red, with narrow black margin. Afghanistan; Quetta. 
18. Genus: Clialeosi opis ’ Swinh. 
Antennae of c? and ? simple, only very slightly swollen towards the tip, with very loose scaling on 
the dorsal side. Forehead flat. Eyes longer (in a vertical direction) than broad. Ocelli are wanting. Palpi 
pointed. Rear tibia with two pairs of long spurs; claws at the base with tooth. In the forewings the cell 
is widely seperated from the costal border, the 1 st to 2 nd subcostals branching from the cell, the 1 st far before 
the centre, the 4 th and 5 th subcostals are stalked with the l sl radial. In the hindwings no transverse veins 
between the costal and the cell, the costal gradually bending towards the costa beyond the middle of the cell, 
the 1 st radial stalked with the subcostal, the 5 th radial before the centre of the cell end. North India. The 
insect appears to me to belong in the heighbourhood of Callidula rather than to the Zygaenids amongst which 
it is placed on account of the developement of the upper submedian vein. 
C. variata Sicwh. (81). c? and ? resemble one another. Brownish black; forewings with white transverse 
bands and a bluish submarginal line, which is white in front; -hindwings white, with hollowed out brownish 
black marginal band, which sometimes extends over nearly half the wing. Khasia Hills, Assam. The specimens 
in the Tring Museum where captured in March, April, May, June, July and December. 
19. Genus: Leptotlirix Heyl. 
Antennae of the <Y long, very finely feathered. Eyes prominent. Rear tibia with two pairs of spurs. 
In the forewings the 5 th subcostal and the 1 st radial and in the hindwings the 2 nd subcostal and the 1 st radial 
as well as the 3 rd radial and the 1 st median on long stalks; the cells on both wings long; outside the end of 
cell on the underside of the forewings, a round cavity covered with a lid (scent organ). ? not known. One 
species from Sumatra. Not known to me in nature; whether it really belongs to the Zygaenidae? 
L. tettigonioides Heyl. With closed wings very much resembles a Homopteron occurring in the same 
region. Body brown, somewhat greenish metallic; the thorax red spotted. Wings long and narrow, brownish 
black; forewings with carmine red oval spot in the cell; a large triangular transparent spot in the centra of 
the hindwings. Expanse 51 mm. Padang-pandjang Sumatra; in the Heylaerts collection.
