was found on imported vines. Professor Comstock reports it 

 from Indiana, and describes it as infesting the lower part of the 

 grapevines from the ground to the shoots of the second year's 

 growth. In comparison with the red scale it is smaller, and 

 the color is lighter, being a yellowish-brown.

[Grubs from three to five lines in length, found in decaying

Between the months of October, 1S82, and March, 1S83, 

 several specimens of grubs were received that were found in 

 decaying wood of fruit trees and grape-vines.

 (Fig. 156/>), l.iut did not succeed in rearing the perfect insect 

 (Fig. loK), as the insects died when casting the pupa skins; 

 however, they were sufhciently matured that they could be 

 identified as to family and genus. The s])eeimens belonged to 

 the genus Lijeliis of Latreille (in Crotcli's Check List, the Bitimia 

 of Hu])ner). Those insects whose grul)S are found boring in 

 decayed wood are not injurious to trees of a healthy growth.
