between the second and third dark line, a conspicuous white patch below the 

 apex. Expanse 13.5 ram. ; .54 inch. 



Hab. — Washington, D. C. 



The specimen, a male, was bred from apple. 



O. kaliniella n. sp.— PI. IV, fig. 3.— Palpi white. Face silvery white, 

 intermixed with fuscous. Head fuscous, sparsely intermixed with white. Thorax 

 and forewing golden brown, with considerable lustre, the latter with six costal 

 and three dorsal, silvery white, obliquely placed spots, with pearly lustre; fir.'^t 

 costal spot at one-sixth, second at one-third, third about the middle and the 

 fourth at two-thirds; these four spots are nearly equidistant, extend obliquely 

 backward to or beyond the middle of the wing, except the third, which does not 

 quite attain it. The second costal spot unites with the first dorsal and forming 

 thus an obtusely angulated fascia. Just before the apex are two approximate 

 costal spots, pointing obliquely forward. First dorsal spot at two-fifths and 

 unites as before stated with the second costal spot. Second dorsal spot beyond 

 the middle, third spot at three-fourths, the last two spots are rather short and 

 somewhat oblique. A small round dot in apical part of wing. Cilia dark brown, 

 a pale periapical line and a white patch below the apex, some silvery white 

 scales at the base, corresponding to the second and third dorsal spots, forming a 

 short line. Hindwings fuscous, cilia concolorous. Underside of body and legs 

 fuscous, with considerable lustre; ventral segments edged with white scales pos- 

 teriorly. Femora and tibise spotted with whitish. Tarsal joints at base and 

 more or less beneath, whitish. Expanse 7.5-S.5 mm. ; .3-. 34 inch. 



Hab. — Penna. (Hazleton) ; Conn. (East River). 



Larva pale green, each segment with a transverse dark line, i 

 with four transversely placed dots ; it makes a pale, orange colored 

 blotch-mine in upper side of leaf of Kalmia angustifolia (sheep- 

 laurel) ; August, September. Imago the following May. 



O. preciosella. n. sp. — PI. IV, fig. 2. — Palpi white, second and third joint 

 with a white, dark fuscous band occupying the middle portion of each. Face 

 silvery white, vertex dark brown, sparsely interspersed with white. Antennae 

 dark brown, finely annulate with white. Thorax dark brown, intermixed with 

 silvery white scales. Forewings dark bronze-brown, with some lustre, markings 

 pure silvery white ; five costal spots, first close to the base, slightly oblique out- 

 wardly and crossing the fold ; second at one-third, obliquely outward and form- 

 ing with the first dorsal spot a curved fascia, widest on the dorsal margin ; third 

 spot about the middle, obliquely outward and not reaching the fold ; fourth spot 

 approximately midway between the preceding and following spot, perpendicular 

 to the margin, triangular and reaches to middle of wing; the fifth spot is just 

 before the apex, extends into the cilia and reaches nearly to the dorsal margin. 

 Three dorsal spots, the first a little further from the base than the second costHl 

 spot; second and third approximate, two-thirds and three-fourths lespt-ctively, 

 triangular, and midway between tneir free ends is the apex of the fourth costal 

 spot. Basal half of cilia pale fuscous, margined externally by a dark fu.scous 

 line, outer half whitish, with a dark line half-way, free margin not tipped with
