 found an elytron of this beautiful beetle under 

 the bark of the willow in Northern New York 

 in July. 



INJURING THE LEAVES. 

 5. Thedaf sp. 



The larva lives in an oval chamber between 

 two leaves, the upper leaf being concave over 

 the site of the caterpillar. 



A caterpillar of a Tliecla f occurred on the 

 willow September 3, at Brunswick, Me. 



Larva. — Head deeply divided on the vertex, much 

 narrower than the body ; pale horn color, with short 

 hairs ; black around the eyes and mouth-parts, also on 

 the occiput, this black stripe usually concealed by the 



prothoracic segment. Body broad oval cylindrical, pale pea-green, with a slightly 

 frosted appearance, due to numerous fine close white dots ; two whitish subdorsal 

 lines, fading out on the supra-anal plate. On the under side of the body are white, 

 short, unequal hairs. Thoracic feet greenish, amber at tip. Length 17 to 18™"".

6. Thanaos sp. 



This Hesperian caterpillar occurred on the willow at Brunswick, 

 Me., August 20. (See p. 459.) 



Larva. — Like that on the aspen, but the head is not so wide and is rather fuller, 

 and entirely dull black. Otherwise the body, the color, the widely-separated sub- 

 dorsal white lines, and the white granulations are the same. Length, IS"™. 



7. Sphinx liiscitiosa Clemens. 



Rev. Mr. Hulst states, according to Professor Fernald, that this rare 

 species has been bred from the willow, but the larva has not yet been 

 described, and nothing more is known of its habits. 



Moth. — Head and sides of thorax gray. Back part of the head above and the upper 

 part of the thorax black, the latter with a fow blue and gray scales on the back part. 

 A broad brown stripe extends from ihe middle of the palpi back under the wings. 

 The abdomen is dull ocher-yellow (gray in the females), with a black line along the 

 middle and a black band broken by dull yellowish white on the edges of the seg- 

 ments along each side. The under side of thorax and abdomen is pale gray. The 

 forewings are pale brown, with the margins sooty black. The band on the outer 

 margin is narrower towards the apex, and has the inner edge wavy. More or less of 

 the veins are black, and a black line extends in along the middle of the cell from 

 the whitish discal dot. This line is double at first, but the two parts unite inwardly. 

 A short black dash rests on the interveuular spaces as far as the apex, the last form- 

 ing the oblique apical streak. Fringes black. The hind wings are bright ocher- 

 yellow (grayish in the females), with a broad black terminal border and a faint
