The only other form of the genus Binsitia described 
is niviferana, Walker, a much smaller insect (exp. ¢ f 
30-88 mm.) with the hind-wings of a buff-yellow colour, 
palpi white, and wing-markings which, though similar in 
character, are different in many ways. 
A single unnamed ¢ of a larger form from the Anda- 
mans is in the collection of the British Museum. This 
may possibly be conspecific with barrowi, but seems to 
differ in the colour of the palpi, which are white. The 
specimen, however, is very much rubbed, though otherwise 
in good condition. 
This very beautiful moth was discovered by Colonel 
Waller-Barrow, R.A.M.C. The specimen described had 
just emerged and was seated on the empty shell of the 
pupa, which was fixed, as shown in the plate, on the twig 
of a small silk-cotton tree (Bombax malabarica, D. C.). 
Colonel Barrow found two other similar pup on other 
branches of the same tree; one of these had unfortunately 
been parasitised, but the parasite (Ichnewmon or Bracon) 
had already matured and escaped. In colour the pupa is 
yellowish-brown, the head is blunt, and with the thorax 
and wing-cases broad and flattened. On the ventral side 
the 4th segment has two closely-approximate tubercles 
placed transversely, between which 1s a longitudinal short 
white streak; 5th to the 12th segments with transverse 
rows of small conical projections ; constrictions between 
the segments strongly marked ; 7th segment with a large 
conspicuous rounded black tubercle on each side, behind 
each of which is a larger pale yellow, or in one of the 
pupze white, tubercle; on the broad flattened truncated 
head, dividing the ventral from the dorsal side, is an im- 
pressed dark line. The pupa is fixed by its tail end ina 
semi-erect position to the twig on which it was found, and 
bears, as can be seen by the illustration, a striking re- 
semblance to the head of a snake and, strange to say, of a 
bird-eating tree-snake (Lycodon aulicus, Linn.) which is far 
from uncommon in Burma. 
At first I was inclined to think that this likeness might 
be protective, but the fact that the pups of Lepidoptera 
are often curiously, almost fantastically, like other natural 
objects is well known. I would instance the pupe of two 
forms of the little Lyczenid butterflies, Spalgis epius, West- 
wood, from India, and Spalgis s-signata, Holland, from
