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 margin a little beyond it 

 and a branch to the tip of the wing. (In European speci- 

 mens the apical branch is represented simple.) Median 

 vein two-branched. The submedian with a long fork at its 

 base. 



Head smooth with appressed scales, face broad and re- 

 treating, slightly tufted above with erect scales. Antennas 

 as 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 antennas, much separated; in the dead insect, 

 drooping and applied to each other. Tongue naked, a little 

 longer than the labial palpi. 



'Li^UjL. speculella. Head, face and palpi pure white. An- 

 tennas slightly fuscous, basal 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 behind, and a short streak 

 of the same hue behind it and nearly parallel to the inner 

 margin. Near the apical portion 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. 

 Imagos on wing the 5th of August. 



The larvas of this genus are represented to make long, 

 tortuous galleries or tracts in leaves, and to quit the leaf 

 when fidl 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 suspect, however, that the mine presently 

 to be described is the work of one of them, although the larva 

 much resembles Phyllocnistis in its habits.
