should regard it, judging from the rather meager description, 

 as closely related to the present species. 

 Types in my collection. 



Nepticula ulmella, n. sp. 



Palpi creamy white. Tuft ocherous tinged with red above, 

 and sometimes with a few dark brown scales behind. Antennae 

 creamy white, broadly banded above with dark brown, so that 

 only a narrow line of the pale color appears between the an- 

 nulations. Eye-caps creamy white. Thorax brownish, some- 

 what peppered. 



Scales of the fore wing creamy white, shading to dark 

 brown at their tips, except where they form a creamy white 

 oblique fascia at the middle of the wing. The general color 

 of the fore wing is thus a somewhat mottled dark brown. 

 The fascia, beginning at the middle of the wing on the costa, 

 reaches the dorsum somewhat behind the middle, and is some- 

 times broken with a few dark-tipped scales. Cilia creamy 

 white. Hind wings pale gray, with a pale bluish luster. 



Legs creamy white. Abdomen above .gray, beneath pale 

 straw-colored. 



Expanse : 4-4.5 mm. / 



The two type specimens of this species were bred from 

 mines on red elm, Ulmiis fiilva Michx., at Cincinnati. The 

 mine starts as a very fine brown, or rarely whitish, line, not 

 very winding in its early course, and at about half its length 

 abruptly enlarging to a breadth of 1 

 mm. From thence it continues to in- 

 crease gradually in width, until it at- 

 tains a breadth slightly in excess, of 2

mm. The broad portion of the mine 

 is usually so much contorted, that it is not possible to trace 

 the course of the mine, the whole having the appearance of an 

 irregular blotch. The cocoon is reddish brown, much flat- 

 tened and is almost circular in outline. Contrarv to the usual
