Fore wings lO-veined; median vein 3-branched, a single vein repre- 

 senting 4 and 5. Hind wings with 7 veins; 3 and 4 furcate on a, long 

 stem ; 2 before the lower angle of the cell. Tongue present.

<? 9 . Head and thorax dull yellow, more or less stained with rosy- 

 brown. Fore wings with a pale yellow costal stripe 

 running to a point and expiring before the tips ; else 

 the silky primaries are dull roseate, shading to fus- 

 cous below the stripe and fading to yellowish at 

 internal margin. Hind wings very pale yellowish- 

 fuscous. Fringes on both wings yellowish; beneath 

 silky yellowish-fuscous. The species expands 17 to 

 19 mil. I have examined four specimens of both 

 sexes, including Dr. Packard's type. Maine, Massa- 

 chusetts. Whether the maxillary palpi are present, 

 iig.i4. I have not yet been able to decide. 



There is no doubt on my mind, after examining Packard's type, that 

 it is the same species ijreviously described by Zeller. It appears that 

 Zeller has recognized a second closely allied species from a specimen 

 sent him by Packard, which differs from hcematica by the thinner, longer, 

 labial palpi, with a brown stripe from the 2d joint outwardly to the 

 tip. The costal stripe is said to be powdered rather thickly with brown. 

 Packard's type does not show any brown powdering, and I cannot 

 recognize any palpal stripe. The palpi are stained with purplish. I do 

 not think it is likely that these characters are specific. My other speci- 

 mens show a variation in size and distinctness of the j'eddish tinge on 

 primaries, but I cannot see either the character pointed out by Zeller or 

 any others on which to infer two species. 



Of this species, Dr. Packard says in the body of his description : — " It 

 has all the structural characters of NepJiopteryx.''^ But in his remarks 

 upon it a little lower down he says : — "Though the antennse are without 

 the usual tuft of scales, and the palpi are longer than usual, I should 

 judge that it was a Nephopteryx,''^ It is, however, as I have above 

 explained, abundantly distinct from Nepliopteryx in structure. 



It is quite necessary that the structure in this group should be fully 

 reported in describing species. I am prevented from identifying Fern- 

 pelia Hammondi with certainty, because the characters of the maxillary 

 palpi and venation are not given by Mr. Eiley. In the absence of an 

 examination of the generic characters in this group, any opinion on the 

 validity of " modern genera" must, I think, be without value. 

 The following is a provisional list of our species : —
