78 SPOLIA ZEYLANICA. 
When handled it emitted a loud continuous note. Speaking 
of this subject, Sharp says (Insects, Pt. I1., p. 382): “ Sphin- 
gidze have been recorded as capable of producing sounds in 
the larval and pupal, as well as in the perfect, instars ; but 
the method in which this is done has not been ascertained, 
except in the case of the imago of the Death’s-head moth, 
which is well known to emit a very audible cry when not on 
the wing ; in this case it is highly probable that the method is 
the friction of the palpi against the proboscis, as stated by 
Réaumur and Landois ; the inner face of the palp is said to 
be marked in this case with fine ridges or striz.”’ 
The above was not the method in the case of the insect 
which came under my observation. It continued to produce 
the noise when the proboscis was held away from the palps, 
and when the palps had been removed. Just where the seat 
of sound production is located I am not prepared to say. 
It seemed to me possible that the source was located in the 
thorax, perhaps internally. 
Some recent Peradeniya Records. 
Legnatia concinna, Morl. M. 8. (Ichneumonide). Reared 
from Lepidopterous pupa. Previously recorded only from 
Dehra Dun, India. 
Pammene isocampta, Meyr. (Tortricide). New species. 
Limnacia metacypha, Meyr. (Tineidze). New species. 
Idiophantis chiridota, Meyr. (Tineide). Larva feeds on galls 
of Trioza sp. (Psyllidze), on Eugenia. 
Argyroploce erotias, Meyr. (Tortricidze). Larva feeds on galls 
of T'rioza sp., on leaves of Eugenia. 
Tinissa torvella, Walk. (Tineidze). Larva feeds on fungus on 
bamboo. 
Batrachedra psilopa, Meyr. (Tineide). Larva feeds in 
interior of galls on the leaves of Heptapleurum stellatum. 
These galls are probably caused by a species of Thrips. 
Cryploblabes proleucella, Hmp. (Pyralidee). Caterpillar feeds 
underneath a web on Coccus viridis, Gr.
