opposite to it. The cilia very pale yellowish and the scales behind tlie cilia of 

 the same hue tipped with dark brown. Hind wings yellowish-fuscous; cilia fus- 

 cous. 



Imago during the latter part of July. 



LYONETIA Hiibner. 



The hiud wings are setaceous. The subcostal is placed nearly in the 

 middle of the wing, is bifid from about the middle sending a small branch 

 to the costa and a long one along the inner margin to the tip. The med- 

 ian vein is very distinct and simple. 



Fore wings caudate^ when denuded. The discoidal cell is very long 

 and narrow, acute behind. The subcostal vein sends two branches to the 

 costa, a moderately long one from the middle of the cell and one just be- 

 hind the acute angle of the disk. (In European specimens there are three 

 subcostal branches, two of which are given oiF near the end of the disk.) 

 The apical branch and the superior branch of the median vein arise at 

 the angle of the disk, the former of which is trifid, sending a branch to 

 the costa at the beginning of the slender tail, another to the inner mar- 

 gin a little beyond it and a branch to the tip of the wing. (In European 

 specimens the apical branch is represented simple.) jMedian vein two- 

 branched. The sjtbmf'dt'aii in'th a Idiig forii <it its /xisc 



Head smooth with appressed scales, lace broad and retreating, slightly 

 tufted above with erect scales. Antennae ns long as the anterior ivings, 

 slender, with a moderate sized basal eye-cap, partly concealing the eyes. 

 Labial palpi slender, cylindrical, ascending (in the living insect) to the 

 basis of the antennae, much separated ; in the dead insect, drooping and 

 applied to each other. Tongue naked, a little longer than the labial palpi. 



L. speculella. — Head, face and palpi pure white. Antennse slightly fuscous, bas- 

 al joint white. Fore wings pure white, with a bronzy-fuscous streak on the inner 

 margin, which is obliquely inclined to the tip of the wing, extending a little above 

 the fold and pointed In-hind, and a short streak of the same hue behind it and 

 nearly parallel to the inner margin. Near the ajiical j>ortion of the wing are four 

 bronzy-fuscous costal streaks, the most interior one of which is oblique and the 

 others nearly vertical and more or less united in the middle of the wing, and at 

 the extreme apex is a black spot. Hind wings darkish gray, with gray cilia. 

 Imago on wing the 5th of August. 



The larvse of this genus are represented to make long tortuous galleries 

 or tracts in leaves, and to (juit the leaf when full fed. I have never bred 

 an imago of this genus, nor can I say with certainty that I have met with 

 a larva belonging to it. I sus])ect, however, that the mine presently to be 

 described is the work of one ot tlicm, altliouLili the larva much resembles
