72 SPOLIA ZEYLANICA. 
fungus at Peradeniya. It looks more like a worm than a 
Dipterous larva, and it flows along with a motion resembling 
that of a snake. It spins silk wherever it goes. It is uni- 
colorous, shining, covered with mucus, and it leaves an 
iridescent mucus wherever it has been feeding. 
The anterior end of the body can be expanded and contracted, 
and when expanded shows two distinct, dark, longitudinal 
bands one on each side of a light-coloured area. When the 
larva is moving, a wave is to be seen passing rhythmically 
along its body towards the posterior end. The puparium, 
which is of much the same colour as the larva, is suspended in 
a thin, mist-like web of silk. It is about 6 mm. long, and has 
a prominent hump in the thoracic region. 
From the puparium, which was formed on May 15th, the 
imago emerged on the 18th. 
Anisodes nebulosata, Walk. (Geometride)—The caterpillar 
was feeding on Ficus sp. 
It is about # inch long, and tapers towards the anterior end. 
The head, thorax, and first segment of the abdomen are 
yellowish-brown, the rest of the abdomen grayish-purple. 
Four lateral oblique, reddish-purple bands occur on segments 
two to five, the three most anterior being edged ventrally 
with yellow. Two narrow, yellowish, longitudinal stripes are 
situated on the dorsum of the head. The anal prolegs have a 
whitish band on the lateral side. 
The pupa is about 4 inch long, and squarely truncate at the 
anterior end. The wing cases, head, and thorax are of a 
dark purple colour, the rest of the body being greenish-purple. 
There is a yellow, transverse stripe at the anterior extremity, 
and this is continued along the wing cases. The pupa is 
suspended by a loop of silk and by silk at the anal region. 
From a pupa formed on October 4th the moth emerged on 
October 11th. In wing expanse it is about 25 mm. The body 
is grayish-white, the wings grayish-white, with large, bluish- 
black blotches and smaller purplish dots. 
Dioptoma adamsi, Pase.—On the night of July Ist I took 
what proved to be the female of this species of Lampyrid. It 
was underneath a hedge, and my attention was attracted to 
it by its very bright, steady light. The luminous organ is a
