The remedial measures planned for the control of Locusta {Pachy- 

 tyliis) migratoria, L., in 1921, consist chiefly of poisoning the food- 

 plants.

The life-history of Nygmia phaeorrhoea, Don. {Euproctis chrysorrhoea, 

 L.) as studied for the most part under laboratory conditions in Stavro- 

 pol, is described at length. Although this moth occurs every year, it 

 is not apparently a very serious pest of fruit trees. It breeds in 

 abundance on wild shrubs, the preferred food-plant being hawthorn. 

 It also occurs on roses, plums and pears, but seldom on apples and 

 cherries. 



Under laboratory conditions pear leaves are preferred to those of 

 apple. Whereas most authors give the number of moults of the 

 larvae as four, seven are recorded in the present observations. This 

 may possibly be due to abnormal conditions in the laboratory.

The caterpillars of Stagmatophora serratella, Tr., are recorded from 

 roots of Antirrhinum majus at Mentone, apparently for the first time. 

 They were found in company with the weevil, Mecinus sicardi, Hust. 

 Previous records and the geographical distribution of S. serratella are 

 reviewed.

 no. 18, 23rd November 1921, pp. 269-271. 



Stagmatophora serratella, Tr., infesting Antirrhinum majus, appar- 

 ently hibernates in the larval stage inside the gaUery. The galleries 

 are made longitudinally upwards, seldom below the collar of the plant. 

 The larvae may ascend and mine the smaller branches, which soon 

 die in consequence, without showing any gall formation. Oviposition 

 occurs in July. 



Mecinus sicardi, Hust., remains at the base of the plant, the whole 

 life-cycle occurring apparently in the plant. The adult weevils emerge 

 from the end of July onwards, those developing towards the end 

 of the summer remaining in the gallery until the following spring. 

 Two different species of Braconids, evidently parasites of Mecinus, 

 were found in the galleries. The structure of the galls produced by 

 S. serratella and M. sicardi is described.
