was tlie larva of Chaetocnema, next to wHch came Oscinella 

 {Oscinis) frit, which in the previous year had occupied the first place. 

 The Hessian fly {Mayctiola destructor) was practically absent. Con- 

 tarinia tritici, Kirby, is recorded as a new pest and proves to be 

 widely spread. Sitones spp. and the caterpillars of Cydia (GraphoJitha) 

 dorsana injured peas and other leguminous plants. Linseed crops 

 suffered seriously from Aphthona eiqjhorbiae, F., and market-gardens 

 from Barathra (Mamestra) brassicae, the caterpillars of which 

 attacked cabbages, onions and other plants. Orchards were attacked 

 by Hyponomeuta malinellus. Lymantria (Ocneria) dispar practically 

 disappeared in the year under report, probably owing to parasites 

 and fungus diseases. A fuller report is in contemplation.

In the year under report the most serious pests of orchards were 

 Hyponomeuta malinellus, Cydia pomonella and Rhynchites auratus ; 

 other species of Rhynchites, as well as Aporia crataegi, Psylla and 

 Euproctis chrysorrhoea, were not numerous. The branch has organised 

 lectures on horticulture for the benefit of the local population, has 

 published pamphlets on the control of pests, and has also been 

 instrumental in supplying the population with sprayers.

This work, in which several assistants of the Station in addition 

 to the author have been associated, is the result of observations 

 extending over three years ; a second part will be devoted to the 

 control of this pest. In Russia, Cydia pomonella first attracted 

 attention in 1840-50, when it was noticed in the Crimea and in the 

 government of Petrograd ; it is now prevalent throughout the whole 

 region in which apples are cultivated. There is no doubt that it 

 occurred in Turkestan before the arrival of the Russians and that it 

 spread independently of the construction of railways. I21 addition 

 to apples, it also breeds in pears and quinces and occasional!}' in 

 apricots, cherries, peaches and plums. 



Early varieties of apples suffer less than late ones, as they are 

 only attacked by one generation, while the latter are injured by 

 three in Turkestan. It appears to be certain that this moth hibernates 

 in the larval stage only and that some individuals begin to do so as 

 early as May. A number of tables dealing with the distribution in 

 time of the various stages are given. Pupation in nature may begin 

 as early as the middle or second half of February, caterpillars 

 exposed to the sun's rays pupating earlier than those in more
