ANNETTE F. BRAUN. 311 



larva is pale greenish yellow, with a darker head. The mine is 

 rectangular, often nearly square, and placed between two veins and 

 uuwrinkled. When complete, the mine is transparent, and the 

 pupa, which is contained in an oval cocoon, is plainly visible.

Antennae grayish, broadly annulate with dark brown. Face and palpi shining 

 yellowish white. Tuft reddish golden. 



Thorax and (brewings shining brownish golden. Pale markings shining with 

 a faint golden lustre. There is a short indistinct median basal streak. Just 

 before the middle is a slightly curved fascia, inwardly margined with blackish 

 scales and outwardly shading into the ground color of the wing. At the begin- 

 ning of the cilia is a second fascia, sometimes divided into a costal and an oppo- 

 site dorsal streak by a line of dark scales. Just preceding the dusted apex is a 

 rather indistinct costal streak. Cilia around the apex, of the wing color, becom- 

 ing gray at the tornus. Alar expanse 5.5-6 mm. 



Hindwings and cilia gray. Abdomen gray. Legs shining gray, tarsi spotted 

 with whitish. 



The form described by Frey and Boll is that in which the pair of 

 streaks at the beginning of the cilia do not unite to form a fascia. 



While only reported from Ohio, Kentucky and Texas, its range 

 is probably co-extensive with that of its food plant. 



The larvae form very small tent mines on the underside of leaves 

 of Symphoriearpos Symphoricarpos (L.) MacM. The mine is placed 

 between two veins, and when mature is much wrinkled. Just 

 before pupation, one half of the mine is lined with silk, and par- 

 titioned off, thus forming an ovoid silken chamber in which the 

 pupa is formed. When the imago emerges the pupa case is thrust 

 through the upper epidermis.
