It is probable that the eggs of P. undulata are also laid in the 

 ground near turnips and allied plants. They hatch in 6-11 days and 

 the larvae begin feeding on the roots of various crucifers, spending 

 the whole larval life of 18-30 days underground. Probably the 

 numerical preponderance of this latter root-feeding species is due to 

 its protection from Ichneumonids and other parasites, from the 

 attacks of which P. nemorum suffers severely.

In this bulletin the methods of dealing with San Jose scale [Aspi-^ 

 diotus perniciosus] and other insect pests that have been increasing 

 in the orchards and gardens of West Virginia are systematically and 

 conveniently arranged ; the treatment of the principal trees and 

 plants are briefly described and reference is made to the proper remedies 

 to be applied. It is hoped that by following the plans outlined the 

 process of spraying may be greatly simplified.

The principal pests of cotton are dealt with in this bulletin, the 

 particular damage done by each being indicated. These include the 

 cutworms, Lycophotia (Peridroma) margaritosa (variegated cutworm), 

 Laphygma friigiperda, (southern grass worm), and Agrotis ypsilon ; 

 the May beetles, Lachnosterna {Phyllophaga) lanceolata and L. cribrosa. 

 Growth of the plant is checked by Aphis gossypii, Glov. (cotton aphis) ; 

 the growing tip is damaged by Chalcodernms aeneus, Boh. (cowpea 

 pod weevil) ; leaf injuries are caused by Alabama argillacea (cotton 

 leaf worm), the grasshoppers, Melanoplus differentialis, Thos., and 

 Brachystola magna, Gir., Tetranychiis telarius, L. (cotton red spider), 

 Atta texana, Buckley (leaf-cutting ant), Estigmene acraea, Dru. (salt-
