Ips longifolia and scale-insects affecting chir pine {Pinus longifolia) 

 were investigated. The seasonal history of the Pyralid, Hypsipyla 

 robusia, which bores in the shoots of toon {Cedrela ioona) was studied. 

 Sack-banding of older trees during the first generation of the moth 

 proved an effective control measure. This method, in combination 

 with early pruning during the third generation, is being tested. 



The following miscellaneous pests were recorded : — Grasshoppers 

 belonging to the genera Oedaleus, Chrotogonus, Teratodes, on chir 

 seedlings in the Punjab ; the Noctuid moth, Hypocala subsaturaia^ 

 Guen., defoliating Quercus incana in the Punjab ; cockchafer larvae 

 on deodar seedlings in the Punjab ; Scolytus (Eccoptogaster) major y. 

 Steb., and S. deodar a on deodar in Madhan State ; an unidentified 

 Lymantrid defoliating chir pine in the United Provinces ; Cistelo- 

 morpha andrewesi, injuring kail in the United Provinces ; the Longi- 

 corns, Derolus volvulus, F., and Glenea spilota, Thom., bred from- 

 Bomhax malabaricum from Kheri ; the Noctuid, Selepa {Plotheia) 

 celtis, Mo., defoliating sal in the United Provinces ; the Longicorn,. 

 Coelosterna scabrator, ¥., on babul seedlings at Kalpi ; an unidentified 

 Lamiid in sandal wood from Madras ; Saissetia nigra, Nietn., on 

 shoots of sandal in Travancore ; the bark-eating caterpillar, Arbela 

 tetraonis, Mo., on young casuarina in Bombay ; the Lasiocampid,. 

 Metanastria repanda, Wlk., on Pinus khasga in Assam ; Cyrtotrachelus 

 sp. on Phoenix paludosa from Burma ; the Longicorn, Aristobia 

 approximator, Thom., on Lagerstroemia flos-reginae seedlings in Burma 

 and scale-insects, including Tachardia lacca, on shoots of Albizziau 

 lebbek, in Burma.

The Capsid, Calocoris angustatus, Leth., does considerable injury 

 to Sorghum vulgare (cholam) and also occurs on a variety of other 

 cereals and grasses, such as Pennisetum typhoideum (cumbu), Seiaiia 

 italica (thenai), Zea mays (maize) and Eragrodis abyssinica (Abyssinian, 

 grass). C. angustattis makes its appearance as soon as the yoang ears 

 begin to push their way out of the enfolding leaf -sheath. In the young 

 florets the eggs are laid under the glumes or in the middle of the floret 

 by means of the long scimitar-shaped ovipositor. The time when 

 the most damage is done is probably when the young grains are in 

 the " milk " stage. The continual sucking of large numbers of nymphs 

 and adults at this time causes the grain to shrivel and often the whole 

 ear is seen to be dry and blackened. Eggs are never laid in seed which 

 is set, and when the grains are hard, it is only the young and immature 

 ones which are chosen for oviposition. In the laboratory, oviposition. 

 always took place at night, and began from two to three days after 

 pairing. Females were never observed ovipositing in the field, so 

 that eggs are probably laid at night under natural as well as artificial 

 conditions. Incubation takes from five to seven days. Great 

 difl&culty was at first experienced in getting the eggs to hatch, and 

 it was eventually found that an extremely moist atmosphere was 

 necessary for them. The eggs hatch in from five to seven days 

 after oviposition, A brief description of each of the five instars 

 is given. The first moult takes place three days after the eggs have-
