(new?) species, of which there is a single worn specimen; while, as 

 above stated, I have found but a single Dcpressaria among over three 

 hundred species found in Kentucky. Of the twenty-eight species in the 

 Fernald collection, fourteen are believed to be new; and, in addition to 

 the Bepr essar he above mentioned, I recognize in it the following 

 species : — Tinea biflavimaculella Clem., T. grisseella Cham., T. carnariiella 

 Clem., Amadrya effrenatella Clem., Adela biviellu Zell., Gelechia dubitella? 

 Cham., Ypsolophus straminiella Cham., Gracilaria purpuriella Cham., 

 and Hyponomenta evonymella auct. Eight of the fourteen new species 

 belong to Gelechia and two to Cryptolcchia. 



D. EUPATORIIELLA, n. Sp. 



Second joint of the palpi iucrassate beneath toward the apex, the 

 scales rather long and loose, scarcely forming a brush, and in the dead 

 specimens not divided. Palpi, head, thorax, and fore wings dark or 

 fuscous-gray; the palpi and wings dusted with blackish atoms, each of 

 which is a minute tuft, and which along the costa take the form of small, 

 obscure, and indistinct streaks ; on the disk, before the middle, one of 

 the blackish atoms is very obscurely margined behind by one or two 

 whitish scales, and about the end of the disk is a minute whitish speck ; 

 apex of the wings rounded ; hind wings not emarginate beneath the 

 apex, pale grayish, with a faint purplish lustre — perhaps pale grayish- 

 yellow would be as correct as pale gray ; abdomen above of the same 

 color, with the hind wings depressed, scarcely tufted at the sides; be- 

 neath it is gray, with a blackish spot on each side of each segment ; 

 legs dark gray or fuscous; under surface of the fore wings grayish-fus- 

 cous; that of the hind wings gray on the disk, the margins pale ochre- 

 ous-yellow, dotted with blackish atoms. Antennas fuscous, scarcely 

 pectinate. The upper surface of the thorax is not dusted, and has a 

 small double or bifid tuft at the apex. Alar expansion eleven lines. The 

 larva feeds upon the under surface of the leaves of Eupatorium age- 

 ratoides, much in the same manner with that of Nothris eupatoriiella 

 Cham. I did not observe it, as the leaves, when gathered, were sup- 

 posed to be folded by the Nothris larva. The imago emerges in the lat- 

 ter part of July. 2 (?, 1 $. Kentucky. 



Both atr odor sella Clem, and lecontella Clem, have the minute bifid 

 tuft on the thorax, as in this species, and the antennas scarcely pectinate. 

 The second joint of the palpi is, however, more brush-like in those 

 species. 



D. FERNALDELLA, W. sp. 



Palpi slender, scarcely brush-like; antennas scarcely pectinate; ab- 

 domen flattened above, scarcely tufted at the sides ; apex of fore wings 

 more acute, and the costa more arched than in eupatoriiella, lecontella^ 

 atrodorsclla, or pidvipenella, and the wings also wider; indeed, in these 

 respects it exceeds perhaps any of the species figured in Nat. Hist. Tin., 

 vols. 1 and 12. The palpi are also unusually slender. Nevertheless, I
