PART II. 
On some new and other species of non-parasitic Hymenoptera in the 
Collections of the Zoological Branch of the Forest 
Research Institute, Dehra Dun. 
By P. CAMERON. 
Introduction. 
I N this paper I have enumerated and described the specimens con¬ 
tained in a collection of non-parasitic Hymenoptera sent to me by 
Dr. A. D. Imms ; Forest Zoologist. 
It includes a description of a new species of Saw-fly and an enumera¬ 
tion of the Aculeate Hymenoptera in the collection with description of 
the species which seem to be undescribed. The Saw-fly belongs to a 
genus, some species of which have proved very destructive to pine trees. 
I have also added descriptions of three new species from Simla and 
one Masuri (Mussoorree?) from my own collection. These are indicated 
by an asterisk.
