NOVEMBER, 1859. 81 



T. solidagonifoliella. Head, thorax and antennae pale 

 yellowish. Fore-wings yellowish, somewhat tinted with 

 fuscous, with a short line of black atoms along the middle of 

 the inner margin, two small patches or much scattered, iso- 

 lated black atoms toward the base of the wing, a patch near 

 the tip on the inner margin, with a minute patch or a few 

 isolated atoms on the costa between the line and patch on 

 inner margin ; at the tip are a few isolated atoms. Hind- 

 Avings very pale yellowish, cilia the same. The male de- 

 scribed. 



Found in the pupa state August 1st in the leaf of a 

 species of Solidago. The mine was on the upper surface 

 and the leaf not folded. The pupa was contained in a 

 slight circular cocoon, attached to the upper cuticle, which 

 formed its upper walls. On August 9th the imago appeared, 

 the pupa case having been thrust through the under side of 

 the leaf. 



T. Zelleriella. Antennas, head and thorax pale yellow. 

 Fore-wings yellowish, with reddish-saffron along the middle 

 and toward the tip ; cilia reddish-saffron, pale yellow on the 

 inner margin. Hind-wings bluish-gray, tinted with yellow 

 externally toward the tip, cilia yellow on the exterior margin 

 toward the tip, internally pale yellowish-gray. 



Female*? The head, thorax and fore-wings yellowish, 

 suffused with reddish-ferruginous, darkest toward the tip. 

 Hind-wings dark gray. 



The larva mines the leaves of oaks in September, making 

 at first a white blotch on the upper surface, but subsequently 

 the upper epidermis becomes brown and the margin of the 

 leaf curled. The head is dark brown ; the body yellowish, 

 with the dorsum of the first segment blackish, with two lateral 

 minute pale spots ; a vascular dark green line. The imago 

 appears early in May, and there is, therefore, a spring 

 brood.
