dots, from each of which arises a line yellow hair. While 

 young the caterpillars eat only the green pulpy tissue of the 

 leaves, leaving the net -work of veins entire; later on they 

 consume the whole of the leaf except its coarser veins. 

 They also frequently gnaw holes or irregular cavities in the 

 young apples. These larvse feed on the leaves of the cherry 

 as well as those of the apple. 



" When full grown they are about half an inch long. 

 They then change to chrysalids within the mass of eaten 

 leaves occupied by the larvre, and ordinarily spin a slight 

 cocoon in a fold of a leaf, but when they are very abundant 

 the foliage is so entirely consumed that they have to look 

 for shelter elsewhere. Their chrysalids are then often 

 found under dry leaves on the surface of the ground, in 

 crevices in the bark of the tree, and in other suitable hiding- 

 places. The chrysalis is about a quarter of an inch long; at 

 first it is of a tawny yellow color, which gradually changes

 produced.

 are sprinkled with black atoms, and have four black dots 

 near the middle, and six or seven smaller ones along the 

 hinder margin. The hind wings are dusky above and 

 beneath, with a glossy azure-blue reflection, blackish veins, 

 and long, dusky fringes. The antennse are alternately 

 striped with black and white. Sometimes the fore wings 

 are of a tawny yellow, in other specimens they are tinged 

 with purplish red, and in some the dots are faint or en-

 folded together and laid flat upon their backs."
