84 TAPERS BY DR. B. CLEMENS. 



white, slightly golden toward the tip, with a blackish dorsal 

 patch on the inner margin near the base. Somewhat behind 

 the middle of the wing is a black oblique costal streak, and a 

 black line curving from the costa to the inner margin. At 

 the tip is a circular black spot, and before it on the costa two 

 short, straight, black streaks. At the extreme tip of the 

 wing are two blackish, diverging streaks in the cilia, with 

 one of the same hue in the cilia beneath the apical spot, 

 nearly joining a black hinder-marginal line ; cilia silvery. 

 Hind-wings silvery, cilia the same. 



The larva mines the upper side of the leaf of Vitis cordi- 

 folla, and perhaps other species, in September and October. 

 The imago appears in September. 



Leucanthiza. 



Head slightly hairy above on the vertex. The front 

 smooth, covered with closely appressed scales, broad, even 

 beneath and somewhat inclined. The forehead or vertex 

 rather acutely rounded above or ridge-like. Ocelli none. 

 The eyes scarcely visible in front, partially concealed by 

 scales. Antennas simple, nearly or quite as long as the 

 anterior wings, the basal joint squamose and but little larger 

 than the stalk. Maxillary palpi none. Labial palpi very 

 slender and drooping. Tongue naked, as long as the anterior 



COX83. 



The fore-wings are almost caudate at the tip ; the posterior 

 lanceolate. The discoidal cell of the fore-wings is acute 

 behind, with tivo veins emitted at its point, one to the costa 

 before the tip, the other to the inner margin. The subcostal 

 nervure sends three short veins to the costa, and the median 

 two approximated veins to the inner margin. In the hind- 

 wings the subcostal and median are both simple, and the 

 latter extended to the tip. 



The head of the larva is very thin and flat, with projecting 

 mandibles in front. The body is much flattened, tapering 

 anteriorly and posteriorly, the rings separated by rather deep
