A new pest has been observed upon Sweetpeas in gardens, viz. the Pea Aphis (Nectaro- 

 phora destructor) which was very bad on some hedges of sweetpeas late in the season. 

 Owing to the wet season in July injury by red spider was only complained of in a few 

 places. Some damage was done by the Green Olover Weevil (Phytonomus nigrirostris) 

 a serious attack having been noticed in the experimental plots 

 at the Central Experimental Farm. The Black Armyworm 

 (Noctua, fennica) attacked both peas and clover, and was also 

 troublesome in gardens. 



Fruit. — The Currant Aphis (Myzus ribis) was rather 

 abundant, but was largely destroyed by the larvae of various 

 lady-birds (Coccinellidae) — The Currant Sawfly (Nematus 

 ribesii) also continues to greatly defoliate currant and goose- 

 berry bushes whenever prompt measures are not taken to destroy 

 the broods. The last brood of the Cherry Slug (Eriocampa 

 cerasi) was very abundant upon both plums and berries. The 

 Oyster-shell Bark-louse (Myrtilaspis pomorum) has been bad 

 in neglected orchards, but such places are naturally breeding 

 grounds for many pests. 



Forest Shade Trees. — The Tent Caterpillars (Clisio- 

 campa) were again enormously destructive, and large areas 

 were completely stripped, and tbe woods were rendered

uninviting by the quantities of webs and larvse. Parasites, however, seem to be 

 nc reasing, and many caterpillars also died from a fungous or bacterial disease,
