OKEITICUS KIRBYI. 115 
strong ; the abdominal feet are ten in number, two 
of them anal. The body consists of twelve segments, 
the sides somewhat prominent, the whole with 
thinly scattered hairs. The three anterior segments 
and the head are yellowish variegated with brown 
marks, the rest of a dull livid colour. When the 
larva is alarmed, it very rapidly shuts up the purse- 
like aperture of its dwelling by means of its man- 
dibles and fore legs, and thus remains in security 
suspended only by a few threads. (Plate IX. fig. 1 
represents a female larva in its case, in the act of 
creeping. Fig. 2, the same larva withdrawn from its 
case.) Having attained its full growth, and about 
to undergo metamorphosis, it fixes one end of its 
habitaculum firmly to a branch by means of silk 
threads spun for the purpose, and allowing itself to 
hang perpendicularly, awaits in this position the 
pupal sleep. (Plate IX. fig. 3 represents the habi- 
taculum of an adult male thus suspended.) The 
pupa of the male is elongated, brown, the abdomi- 
nal segments with a rust-coloured ring, the front 
somewhat carinated, and each segment furnished 
with a double series of dorsal spinulse ; that of the 
female is of the same colour, but much tbicker. 
When the male appears in the winged state, he 
is found to be of a uniform black colour glossed with 
purple ; the upper wings rather narrow and elonga- 
ted, the under pair small and slightly produced at 
the anal angle. The abdomen is extensile and 
elongated; tarsi rufescent; mouth pale; antennae 
strongly pectinated from the base to the middle,
