166 SPOLIA ZEYLANIOA. 
a single trough above and below (h, 7), capable of carrying onvelopes 
of a larger size. 
(In figs. 5, 6, and 7 the two lids have been omitted for sake of 
clearness.) 
These boxes are designed for three sizes of envelopes, which gives 
a sufficient range for butterflies of any size. Size 1 is made from a 
rectangle 8in. by 5in. Size 2 from a rectangle 6 in. by 4in. Size 
3 from a rectangle measuring 4 in. by 2? in. 
It is found in practice that a box made according to fig. 4 will 
carry, without overcrowding, from 100 to 130 full envelopes in the 
larger trough, and from 175 to 200 in each of the two smaller spaces. 
Design 2 will hold in each of the four spaces 225 Lycenide, making 
a total of 900 insects. Design 3 will hold 75 or more filled envelopes 
in each of the two spaces. 
For convenience of examination the insects should be arranged 
in families : the genera alphabetically in each family, and the species 
alphabetically in each genus. Subsequent additions can be slipped 
into their places without disturbing those already in position. To 
keep the envelopes in place when the troughs are only partly 
occupied, triangular blocks of cork about ?# inch thick can be 
employed. For use as collecting boxes the troughs can be charged 
with empty envelopes, and the cork triangles will serve as markers 
to separate the unused envelopes as they are filled. 
The boxes illustrated are of the simplest design, as made by a 
local tinsmith in Ceylon. They can be improved by a coating of 
black japan on the outside. 
Messrs. Watkins & Doncaster have adopted this design, and are 
turning out boxes (to suit, their special-sized envelopes) in stout 
japanned zinc, with perforated partitions at the end of each trough 
for the reception of naphthalene or camphor.

15. On a curious Scolopendriform Caterpillar (‘* Homodes fulva,” 
Hampson).—Three species of Homodes (crocea, Guen. ; vivida, Guen. ; 
and fulva, Hampson) are recorded from the Indian region, but the 
larva of none of these species has been described. 
A small dull-coloured larva was recently found wandering about 
in the verandah of my laboratory, Its form and movements were 
so peculiar that I had to examine it with a lens to assure myself that 
it was really the caterpillar of a Lepidopterous insect. 
Fig. 8a shows a bird’s-eye view of the larva (natural size). The 
lateral processes, which might at first sight be mistaken for the 
limbs of a myriopod, are stout’spatulate hairs.
