In the course of further work on the occurrence of the Longicorn, 

 Hoplocerambyx spinicornis, in the sal [Shorea robusta] forests of Dehra 

 Dun, particular attention was paid both in the insectary and in the 

 field to the effects of soil and rainfall conditions on the incidence of 

 the borer. It is now known that in a series of years of high rainfall, 

 the increase of the borer is encouraged and the resistance of the plant 

 is lowered, while in years of low rainfall the reverse occurs. If the 

 monsoon fails during a borer epidemic, the proportion of trees fatally 

 attacked is reduced (in spite of the relatively increased incidence of 

 the borer) to such an extent that the pest receives a marked check. 

 Remedial measures have been based upon these facts and are being 

 tested. During survey tours it was discovered that Hoplocerambyx is 

 rare or absent in the dry and hill type of sal forests, and that in the 

 moist and valley type of sal its presence is usually secondary to 

 attack by Polyporus shoreae. The frequent mortality of sal where 

 borers are absent indicates that these insects are essentially secondary 

 factors that under epidemic conditions may cause the death of 

 weakened trees. 



Studies have been made of the development and economic importance 

 of Aeolesthes holosericea, Xylotrechus smei, Platypus spp., Diapns spp. 

 and Xyleborus spp., and of the effect on their prevalence of chmber- 

 cuttings and of girdling and felling without removal of inferior species. 

 Calandra shoreae (seed weevil) is found to have many dipterocarp 

 food-plants.

This paper describes the following species of a group of Chalcids 

 that the author is inclined to regard as parasitic rather than phyto- 

 phagous: — Otitesella digitata, Westw., 0. epicarioides, Grnd., 0. africana,
