THE CANADIAN ENTOMOLOGIST. 31 



(beneath the caudate tip) have a metallic lustre. Al. ex. j£ inch. This 

 species is so similar in the position of its markings to luteostrigella, that 

 it may prove to be the same species, but its greater size and fuscous 

 instead of golden markings induce me to consider them as distinct. 

 Texas ; Belfrage. 



GRACILARIA. 



G. rhoifoliella. N. sp. 



Face and palpi white, with the apex of each joint of both pairs of the 

 palpi, and some scattered scales along the under surface brown. Anterior 

 and middle tarsi white, with the joints faintly tipped with brown ; tibiae 

 of the hinder pair whitish beneath, and with white spurs tipped with 

 brown ; tarsi white. Thorax and primaries brown with a yellowish 

 tinge, but becoming darker brown towards the apex and on the costa near 

 the base, and with bright purplish reflections in some lights ; along the 

 extreme costa and sometimes on the fold is a series of dark brown dots ; 

 trigonal mark absent ; ciliae fuscous ; venter white, dusted with dark 

 brown. AL ex. y? inch. 



My first specimens came to the light at the Bee Spring Camp of the 

 Kentucky Geological Survey, near Mammoth Cave, but a few weeks later 

 I bred it in Northern Kentucky from larvae mining the leaves both of the 

 "Poison Oak" (Rhus toxicodendron ) and the Sumach (Rhus copalina.) 

 It mines either side of the leaf, and the mine, at first linear, is at some 

 part of it widened and excavated like the tentiform mine of some species 

 of Lithocolletis ; sometimes the tentiform mine is not connected with the 

 linear mine. After it has ceased feeding in the mine, it rolls the leaf 

 rather clumsily downward from the tip. 



G. inornatella. N. sp. 



Palpi white stained with ochreous yellow towards the tip of the second 

 joint, and with an ochreous yellow annulus before the tip of the third ; 

 head and antennae white, the antennae annulate with pale yellowish 

 ochreous. Thorax and fore wings white, suffused with pale reddish 

 ochreous, the basal part beneath the fold more whitish ; and there is an 

 oblique white fascia before the middle nearest the base on the costal 

 margin. In some lights the wings show a purple gloss. The hind legs 

 are missing in the single specimen before me ; the anterior and middle 

 pair are of the general hue on their anterior surfaces and white behind,
