cone, long and spindle shaped, and near one end of the cone 

 the leaf is prepared for the emergence of the adult. Upon 

 emergence the pupa is thrust through the previously-prepared 

 portion of the leaf, and the empty skin is left protruding from 

 the cone. (See figure in Kellogg's American Insects, p. 378, 

 1908.) 



Gracilaria quercinigrella, new species. 



Venation : Fore wings 12 veins, all separate, 3, 4 and 5 

 somewhat approximate, 2 far from angle of cell ; hind wings 

 with 9 veins, 8 ending at the hump on costa and extra vein 

 arising out of the base of 7 just below the hump. 



Face pale gray. Crown somewhat roughened, expansible 

 tufts above eyes. Labial and maxillary palpi white with a 

 few dark scales which are more abundant outwardly and 

 toward the tips of the joints; the second joint of the labial 

 palpi with a distinct tuft. Thorax and fore wings with a white 

 ground color overlaid by numerous yellowish and black -tipped 

 scales, giving an ashy gray appearance ; the markings very 

 poorly defined, the basal area of the wing above the fold dark 

 gray, below the fold much lighter, just beyond this dark area 

 is a pale gray fascia which extends, slanting outwardly, clear 

 across the wing, beyond this the pattern is indistinct, but there 

 seems to be a faint indication of several concave, whitish 

 fasciae toward the tip of the wing. The cilia are white with 

 two lines about the apex. Hind wings pale gray. On the 

 under side the fore wings, a portion of the hind wings and the 

 legs are heavily shaded with red-brown. The front and middle 

 legs have whitish tarsi annulate with rusty brown at the tips 

 of the segments, the tibiae and femora nearly covered with red- 

 brown, hind legs yellowish, tarsi and tibiae unshaded, femora 

 and coxae shaded with red-brown. Abdomen yellow gray 

 above, whiter on under side speckled with brown. Antennae 

 about as long as fore wings, pale yellow gray annulate with 

 brown. Expanse, 10 mm.
