from the origin of 6 ; 9 out of 8 a very short furcation ; 1 more or less 

 distinctly furcate at base 5 5 prolonged inward beyond the point where 

 the closure of the cell is indicated above and below. Hind wings with 

 vein o joined to 4 by a very short cross-vein ; cell open.

c? $. Fore wings dusty yellowish-gray with powdery black lines. 

 Inner middle line marked on costa by a black dot ; below it is obsolete, 

 or partially indicated. A black discal dot near the costal spot of the 

 inner line. Outer line irregularly denticulate, better marked superiorly, 

 where it runs obliquely outward to median nervules, produced about 

 vein 4, thence running inwardly below vein 3, whence it descends, very 

 slightly outwardly projected, to internal margin. Terminal field wide; 

 a diffuse, broad, brownish or blackish shade-band marking the veins. 

 A terminal series of distinct interspaceal black marks becoming con- 

 tinuous inferiorly. Fringes pale, interrupted with brown and with a 

 dotted line. Hind wings fuscous, the veins darker marked ; a discal dot 

 very near the base and costal border ; a terminal distinct line ; fringes 

 pale, with a dotted brown line. Beneath yellowish-gray, sometimes 

 suffused with blackish ; a corumou line and discal dots ; the terminal 

 shade on fore wings less prominent than above, and here also continued 

 on secondaries. Several specimens examined from Oldtown, Me., Mr. 

 Charles Fish ; also one male from Kansas, Prof. Snow, and one female. 

 Long Island, N. Y., July 6. The type of horealis was from Cambridge, 

 Mass., Mr. J. C. Merrill. Dr. Clemens's type was from 

 Farmington,Coun., Mr. Edw. Norton. The average 

 expanse of my specimens is about 22 mil. 



MoCHLOCERA Zellcr. 



Male antennal process as long as the thorax, or 



nearly so. Male maxillary palpi scaled. Labial palpi 



a little exceeding the front, curved upward, with the 



third joint shorter and more distinct than in JEpipa- 



schia. Neuration of EpipascMa, but on primaries viein 



rig 2. 1 is simple at base; vein 5 is not inwardly prolonged, 



and vein 8 is thrown off at about one-third from the origin of 6, a little 



nearer to the origin of 9, which latter is longer, being here thrown off 



before the point of its origin in Epipascliia.
