APODERUS SP. 35 

Localtty from which the insect has been reported. 
The writer obtained this beetle in June r1rgor on the banks 
of the Sutlej river, where it flows between the Kulu and Bashahr 
States, at elevations of between 2,500 and 3,500 feet. 
Relations to the Forest. 
Whilst marching up the Sutlej Valley between Nirth and 
Rampur the writer noticed that the sissu trees on either bank 
ef the river were being heavily defoliated. The trees were 
growing either in clumps or scattered here and there in the 
river bed and on the terraces existing on either side of the 
stream. An examination showed that the defoliation was not 
due to any ordinary leaf*feeding insect. A certain amount 
attributable to the latter cause was certainly going on, but the 
serious part of the work was due to quite a different form 
of attack. The first thing that attracted notice was the fact 
that the crowns and ends of all the branches of the trees, 
consisting of long yellowish green shoots just developed, or in 
the course of development, were either totally leafless or rapidly 
becoming so, The effect to the eye was as if one had taken 
the new leaf-bearing twigs into the hand and pulled them 
through the closed palm so as to remove the new leaves, 
leaving behind only the long, bare, whippy, yellow-green new 
shoots, A closer inspection, however, showed that these 
shoots were not entirely bare. In many cases small portions 
ef a leaf, looking as if they had been snipped off either 
just above the juncture of the stalk with the leaf or at the stalk 
itself, were visible and often hanging down from these a 
small bundle of rolled-up leaf. These latter enabled me to 
perceive what was taking place. A leaf-rolling insect was at work 
and in each of these bundles, as already described, an egg had 
been placed by the mother beetle, and in so laying their eggs the 
beetles were stripping the sissu trees of the entire crop of their 
new leaves, In some cases the little bundles had dropped, in 
ethers they had turned black and were ready to do so, whilst 
others again were stil] green and fresh, and I was able myself to 
see Others inthe course of formation. Every tree on the 16 miles 
of river I inspected, both on the Bashahr and Kulu sides of the
