FAMILY iEGERID^. 223 



The cocoon is constructed partly out of the castings of the larvjr, which, |.y means of 

 gum ami silk, is fornud into i> common oval shell suiTdUmling tlie jiujia : these may he 

 tlestri)yed at once. 



To jirutect a tree. Dr. 1 Iakius long ago recommended the use ol' slieathing paper, secured 

 by strings and matting to the neck of the tree after removing the earth. This paper should 

 be cut in strips eight or nine inches wide, and fixed below the soil by means of mortar and 

 fresh loam. Tho application requires renewal every spring ; l)Ut whatever means may be 

 adopted, careful examination during the months of June and July should not l>e neglected. 

 Wounds that may be made in the removal of living bark and wood, should be covered 

 with grafting wax, or something to protect the surface from water. 



The currant-bnsh is injured by the JEgcria (ipt/Nfcnnis, which is not a native of this 

 country, but is of European origin. The eggs are laid near the biuls, and, when hatched, 

 the larv.T penetrate the bark and wood, and even into the pith : the stems become brittle ; 

 but, belbre this, they show marks of disease by yielding an inferior fruit. 



Dr. H.\RRis describes another insect allied to the iEcERiA, the TrochUium denudatum 

 ( H.\Ruis) : the color is brown ; the edges of the collar and of the abdominal rings, the 

 shins, the feet, and the underside of the antennae are yellowish ; the forewings opake,and 

 the hindwings transparent. It attacks the ash : this tree, especially the english mountain 

 ash, when planted for ornamental purposes, seems to be quite as lialde to the attacks of 

 these borers, as the peach ; and hence it requires the same attention and treatment. 



Glaucopis pholus. ( Plate xl, fig. 3.) 



Glaucopis (Fabricius). Sphinx pholus ( Drury). 

 Antenna black, and thickest in the middle. Upper side black : basal half of the wings 

 orange. Beneath the color is paler, but after the same pattern. 

 The larva feeds on lichens growing upon stones, and hence is more common in bleak 

 stony places.
