Tincina of the Central United States, 103 



nearly straight white dorsal streaks, respectively, opposite the second 

 and third costal streaks, both dark margined before; the dark margin 

 of the second being at its apex, confluent with the dark brown hinder 

 marginal line, which extends along the base of the dorsal and apical 

 cilise. Extreme costal ciliae tipped with dark brown, ciliae white, apical 

 spot black. Secondaries pale yellowish white, cilia? white. Both j)airs 

 fuliginous beneath. Al. ex., one fourth inch, Kentucky. 



The larva is cylindrical, and makes a small tentiform mine on the 

 under surface of leaves of white oaks (Q. alba and Q. bicolor). The mine 

 is at the edge of the leaf, and the leaf is folded down over it. 



This species resembles the preceding one very closely, and I would 

 place it between that species and L. lucidicostella. 



L. unifasciella (p. sp.) 



Face, palpi, and under surface of the antennae, silvery white. Upper 

 surface of the antenna3 dark brown, tuft silvery white, mixed above with 

 pale golden, which becomes deeper at the sides ; thorax and anterior 

 wings rich reddish orange ; there is a silvery white, slightly oblique 

 fascia just behind the middle of the wing, nearest the base, on the 

 dorsal margin, and curving slightly toward the base, near the costal 

 margin, with small dark brown spot on the costa, margining it before, 

 and distinctly dark, margined behind, the dark margin being produced, 

 both as a streak along the costa and a parallel one along the middle of 

 the wing, the streaks spreading and uniting about the beginning of the 

 costal ciliis, thus inclosing an oblong patch, which is not dusted; the 

 fascia is but little angulated, and does not have the appearance of two 

 confluent streaks ; apical margin, along the base of the dorsal cilise, 

 very densely dusted with brown — the dusting in some specimens being 

 connected with the dusted streaks above mentioned. A dark browu 

 wider margined line at the base of the dorsal and apical cilise. CiViSQ 

 yellowish. Al. ex., one fourth inch, Kentucky. 



The larva belongs to the second or flat group, and mines the upi)er 

 surface of leaves of the black oak (Q. tinctoria). The maculae and 

 transparent spots are distinct. Head whitish. First and second maculae 

 dark brown, the others pale yellowish or pale brown. Frass scattered, 

 mine oval at first flat, but afterward corrugated along the middle. 

 It belongs to the same group as L. bethunella, which also mines the upper 

 surface of leaves of Q. tinctoria ; and it resembles bethwiella closely as 

 to the fascia, dusting and general color, but it lacks the costal and 

 dorsal streaks of that species, and the fascia of bethunella is formed by
