Pyrausta nubilalis is very widespread in European Russia and in 



Siberia, and is particularly common in the South, injuring maize, 



millet, hemp and hops ; in the province of the Don, where no hemp 



and hops are cultivated, it chiefly injures maize and to some extent 



millet. The various stages of the pest are described and figured ; the 



eggs are laid about the middle of July on the surface of the stems and 



in two weeks the caterpillars emerge, feeding first on the surface and 



then penetrating into the stem, where they remain for the whole of their 



life. The caterpillars winter inside the stem, pupating only in April 



or May of the following year, the pupal stage lasting about three weeks. 



The usual remedy is the burning of the stems after the harvest, but 



in many steppe-estates the stems are purposely left over the winter to 



retain the snow ; it is therefore suggested that experiments should 



be made with insecticides, applied at the time when the young, newly- 



liatched larvae are still on the surface of the stems.

 The adults of Lethrus apterus appear early in spring and prepare 

 'burrows along roads and similar uncultivated places in which each 

 female lays from 8 to 12 eggs. These burrows are stored with food 

 for the future larvae, consisting of fragments cut from plants, vines 

 being especially damaged. The larvae hatch in 12 days and live 

 tor a month or more ; the pupal stage lasts two weeks and the 

 newly emerged beetles remain in the soil over the winter. Against 

 this pest, trenches should be dug round plantations, the sides of the 

 trenches being undercut so that the bottom is wider than the top. 

 Where no trenches are practicable, the plantations should be surrounded 

 with straw bands smeared with tar. Spraying with Paris green or 

 .any other arsenical must be done once as soon as the beetles appear 

 and again during the period of the gathering of food supplies. Hand- 

 picking should also be carried out at this time. The peasants in 

 Bessarabia apply a remedy that is based on the inability of the beetles 

 to creep up smooth surfaces. Each vine-stock is surrounded with a 

 closed ring made of iron or wooden hoops, or specially prepared from 

 sheet iron. These are kept on the plants for not more than one 

 month and, if taken care of during the winter, will last for 10 years.
