margin of the wing divided into two fiuger-like lobes, the upper, or costal oue, being 

 double the leugth of the lower, or dorsal lobe. There is a sligh*; ditference in neura- 

 tioD between the North American and European forms, the species here described 

 having the discal cell of the fore- wing not narrowed to a point, as in iSuellen's figure 

 (Tijd. V. Ent.j XIX, PL 1), and the veins that leave its margins are distinctly separate 

 from each other at their bases ; moreover, the apical vein, which is forked, throws its 

 lower branch almost to the apex of the wing, or very closely above it. The long and 

 slender apical joint of the labial palpi also serves to distinguish the American from 

 the European species. 



Dactylota snellenella sp. u. 



Antennce, simple; basal joint scarcely wider than the stem. 



Palpi, recurved, slender; second joint longer than the head, clothed with short di- 

 verging scales beneath, smooth above ; apical joint very slender, smooth, longer 

 than the second, in this respect differing from khikereUa Snell., which has much 

 shorter palpi. 



Tongue, rather long, scaled at the base, naked beyond. 



Sead and tliorax, greyish, sprinkled with brownish scales. 



Fore-wings, elongate, broadly lanceolate, costa slightly arched near the base; with 1"2 

 veins, 7 and 8 from a common cell ; greyish, sprinkled with brownish scales, hav- 

 ing a slight iridescent hue in a strong light. There are 3 very conspicuous patches 

 of very dark umber scales, the 1st within the basal fourth, adjacent to the upper 

 edge of the fold; the 2nd within the basal half of the disk, slightly above the mid- 

 dle of the wing ; the 3rd, ;it about the end of the cell, larger and more conspicuous 

 thau the preceding two, is followed by an ill-dehned band of very pale grej- 

 scales, stretching from the costal to the dorsal margin ; the apical portion of the 

 wing is faintly sprinkled with similar pale scales; a narrow line of subochreous 

 scales runs nearly parallel with the costa, from the base for about one-third of 

 the length of the wing; a few dark umber scales are also observable about the 

 middle of the fold; cilia very long, rosy-grey, sparsely dotted with brown along 

 their base. 



Hind-wings, $ , shining, pale greyish, also iridescent in a strong light ; as wide as 

 the fore-wings ; costal and dorsal margins parallel ; apex produced, obtusely 

 pointed; apical margin deeply indented, forming a short obtuse second lobe; 

 the fissure is rounded at the base; abdominal angle rounded ; the abdominal 

 margin neaiij' straight; cilia very long, having an ochreous lint. On the under 

 side is a tuft of long, hair-like scales from the middle of the base, lying parallel 

 to the upper edge of the 2nd lobe. 

 In the 2 the hind-wing, although deeply indented below the apex, is not divided 

 into two lobes, its form being rather that of the genus Cleodora ; the tuft of hairs 

 on the under side is also absent. 



Abdomen, greyish, rather wide and flattened; anal tuft faintly ochreous. 



Exp. al, l?^-"". 



Habitat, Arizona. 2 <? and 2 $ received from the late H. K. Morrison in 18S3. 



Type, i 9 , Mus. fVlsm. 

 The species is named after the well-known author of "DeVlinders van Neder- 

 land," who, in one of his numerous and valued papers on Microlepidoptera, first 

 described the European representative of this genus.
