102 Tineina of the Central United States. 



dorsal streaks all faintly dark margined before, the dark margin of the 

 first costal being the most distinct ; wings not dusted, but with an exceed- 

 ingly minute and indistinct apical spot. Al. ex., one fourth inch. 



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

 under surface of the black jack (Quercus nigra). This species ap- 

 proaches most nearly to L. argentinotella, Clem. It is one of the Avil- 

 low oak miners mentioned in the Canadian Entomologist, vol. v., p. 1G6. 



L. quercibdla (n. sp.) 



Glistening snowy white; extreme tips of the antennae brown. A 

 pale golden basal streak begins on the costa, at the base, and passes 

 l)ack parallel with the fold to the golden apical portion of the wing, 

 and is interiorly very faintly dark margined ; apical third of the fore 

 wing pale golden, with a black apical spot, and dark brown hinder mar- 

 ginal line at the 6a.se of the dorsal and apical cilice. In the pale golden 

 portion of the wing are three silvery costal and one silvery dorsal 

 streak, all dark margined before. The first costal streak is larger than 

 the others and its dark margin is somewhat oblique ; the dark mar- 

 gins of the other streaks are straight ; the dorsal streak is opposite to 

 the first costal. Extreme costal cilias tipped with fuscous. Al. ex., 

 one fourth incli. 



Tlie larva is cylindrical, and mines the under surface of the leaves of 

 black jack {Quercus nigra), and the mine is usually near to the edge. 

 It is one of the. mines mentioned as mining willow oaks. Can. Ent., 

 vol, iii., p. 166. 



This species is between L. Clemensella and L. lucidicostcUa, having 

 the basal streak as in the latter, but having a less portion of the wing 

 golden, and a larger portion white, as in Clemensella. 



L. fuscocosteUa (n. sp.) 



Glistening snowy white ; antennse pale yellowish ; primaries snowy 

 white, with the apical half pale golden, with a pale golden basal streak 

 extending from the base of the costa along the costal margin to the 

 golden apical half of the wing, and internally very faintly dark mar- 

 gined ; in the golden apical part of the Aving are fo%ir short and (except 

 the first) straight costal streaks, all faintly dark margined before, the 

 dark margin of the first being more distinct than those of the others, 

 and also being oblique and produced along the extreme costa to the 

 base. The streaks are nearly equi-distant. There are two short and
