PHAUDOPSIS; AKESINA; CALLIZYGAENA. By Dr. Iv. Jordan 
igneola. 
basalis. 
tiivimacula. 
3. Genus: I*haudopsis Hamps. 
Tongue short and thin. Frons broad. Palpi thin and very long, extending to the base of the 
antennae. Ocelli wantig. Antenna setifonn, very pointed, in the d* bipectinated, the last 6—8 segments 
feebly dentate; in the ? with one row of pectinations, on the underside with the exception of these roughly 
scaled. Spurs of all the tibiae long, hindtibiae with 2 pairs, the proximal pair before the last third of the 
tibia. Wings long; veins of the forewing branching off from the cell, 5 subcostals, the 1. directly behind 
the middle of the cell; apex of the cell feebly angled; 2. and 3. radials confluent, 2. median from the angle 
of the cell. In the hindwing 3. radial and 1. median stalked. — One North Indian species. 
P. igneola Hamps. (If). <? and ? different in the colouring of the wings. Body purple-black; head, 
with the exception of a frontal spot, and the upper and underside of the thorax red. Antenna with white 
tip. Forewing in the c? bronze-brown, a broad costal streak and 3 thin longitudinal lines red; the forewing 
of the ? red, the narrow distal margin, as well as a proximally pointed longitudinal spot in the middle of 
the marginal band black. Hindwing smoky black, proximally somewhat glassy and in the ¥ reddish. — 
Assam: Khasia Hills, in April. 
4. Genus: Akesiua Moore. 
Mouth-parts quite aborted. Ocelli wanting. Antenna of the cd with very long thin pectinations. 
Foretibia without spur; spurs of the middle and hindtibiae veiy short, only the apical spurs of the hind- 
tibia present. The body and the broad rounded wings covered with hair-scales. In the forewing only 
3 subcostal veins present, the first anastomosing with the costa, the other two stalked, the upper submedian 
weakly developed. — One species, from North-West India. 
A. basalis Moore. Body and base of the semitransparent wings brownish yellow, rest of the wings 
blackish. — Kangra. 
G. Subfamily: Ghalcosiinae. 
Tongue and palpi present; the latter often short, separated from the eye by a stripe on the face which is 
usually scaled. The stripe which surrounds the eye at the back broad, sometimes without scales, always with fine 
erect hairs. Ocelli present. Antenna in cd and ¥ pectinated and dentate at least before the tip. Foretibia 
always without spur; middle and hindtibiae with one pair of short spurs. Anal segment of the ¥ usually modified 
into an ovipositor. — The species of this central subfamily are almost all more or less metallic green or blue, with 
red, yellow or white markings. The subfamily includes very diverse looking elements, all of which, however, can 
be distinguished from the Zygaeninae by the absence of the spur of the foretibia. The species are partly very 
variable, even in the neuration of the wings, and in many genera the sexes are so dissimilar that until quite recently 
cd and $ were placed in different genera. The subfamily is developed principally in the Indo-Malayan Subregion. 
Many of the genera which occur there reach into the Palaearctic Region. Only very few extend into the Papuan 
Subregion, which possesses a few endemic genera that do not occur in the Indo-Malayan district. In their habits 
the Chalcosiids are very similar to the Zygaenids. The larger, broad-winged species have mostly a still heavier 
flight; of only very few forms is it known that they fly rather high above the ground in company with other 
Lepidoptera, e. g. Pierids. Many dark forms are fond of resting on tree-trunks. The bizarre markings of many 
species suggest that they mimic spotted flowers. The forms which resemble Geometrids, Arctiids and other Hete- 
rocera, are much more rare than these. This may in part be due to the fact that the Chalcosiids are much less 
easily started up and consequently escape the net of the collector. The rarity of the Chalcosiids in comparison 
with the similarly marked Geometers in New Guinea collections for instance is very striking. In India on the 
contrary the Chalcosiids which resemble the Euploeids and Danaids are mostly very common, as are also the forms 
resembling the Fulgorids. — The short thick larva bears on all the segments, with the exception of the small head, 
narrow or broad tubercles covered with bristles. The pupa lies in a fii’m cocoon, which is fastened on the upper- 
side of a leaf, more rarely on the stem, but is also sometimes concealed low down on the plants close to the 
ground, or even under its surface; before emergence, as in other Zygaenids, the anterior third of the pupa is pushed 
out of the cocoon. 
1. Genus: Callizygaeua Ilamps. 
H and ¥ similar; frenulum simple also in the ¥. Head broad, frons flat; antenna with long thick 
pectinations, which are much shorter towards the base. Distal segments only weakly dentate, reminding one of 
Procris statices. Legs short, foretibia broad, first tarsal segment short. Abdomen broad, laterally covered 
with hairs. Forewing elongate-triangular, cell truncate, all the veins arising from the cell or the 2. and 
3. subcostals stalked, 1. median near the angle of the cell; in the hindwing all the veins from the cell. 
Ovipositor of the ? broad. — Pretty species, with partly transparent hindwing and red-marked abdomen. 
Indo-Malayan. 
C. auratus. Black, collar and two bands on the abdomen red or the latter yellow above; thorax 
and forewing covered with metallic green scales, which are thickened into an indistinct band on the fore¬ 
wing before the middle. A white spot in the cell of the forewing. Hindwing thinly scaled, semitransparent. 
2. and 3. subcostals of the forewing stalked. Ceylon and South India. — nivimacula Fldr., from Trincomali 
in Ceylon, has a rather distinct metallic band before the middle, but has otherwise no metallic scales and
