PLATYSOMA SP. 35 
ee 
(22 
In the third week of the month the beetle was found in some 
numbers beneath the bark and in the wood of dying girdled blue 
pine trees. The trees were infested with the Rhyncholus wood- 
borer (see No. 2, p. 198), and the Platysoma was found in their 
galleries and also on the sapwood beneath the bark. 
This beetle was again found fairly plentifully in the adult 
stage towards the end of June beneath the bark of recently 
felled deodar trees which had been attacked by the two Scolytws 
beetles, S. major and S. minor. These latter with their larve 
were very numerous in the bark and sapwood (see No. 2, pp. 
203-212), and the Histerids were feeding upon the larve and 
possibly upon the adults. 
A few days later I discovered the same Platysoma 
beneath the bark of a large dead spruce tree, the wood of which 
was being attacked by the borers Ahyncholus sp. and Hylastes 
sp. The Histerids appeared to be feeding upon these. 
Locality. 
This Platysoma appeared to be common throughout the 
Jaunsar and neighbouring Tehri-Garhwal forests in the blue 
pine, deodar and spruce zones (about 5,500 to 9,000 feet). 
Further observations required. 
I have not yet found the larval or pupal stages, and [ do 
not know how many generations this insect passes through 
in the year. It is evidently not uncommon in the locali- 
ties above mentioned; but there still remains much to be 
observed on its habits, and it will be of especial interest to 
obtain the other stages of its metamorphosis and to ascertain 
its real importance in the forest.
