spot in their interspace; in continuation of the line connecting the 

 median spots are two minute roundish or transversely oval obso- 

 lescent spots above, and a small roundish spot below; in the place ol 

 these, the S has the sexual bar, which is indistinct, black, inter- 

 rupted; it starts from the median nervure, just within, or at its last 

 divarication, and passes in a straight, or very slightly incurved line, 

 directed sharply inward to the first median nervule, so as to form with 

 the latter an angle of about 45°; continuing fi'om a point as far out- 

 side of this as its own width, it crosses the interspace between the 

 median nervules, making a slight outward curve nearly parallel to the 

 outer margin. 



Beneath, dull chestnut-brown, the whole apex of both wings cov- 

 ered with a bloom of pearly white scales, lower outer angle of 

 primaries dull brownish-white; the spots of the upper surface of the 

 primaries are repeated beneath, but whiter; between the subcos- 

 tal and median spots is a large quadrate spot, parallel to the costal 

 border, of a dull brownish tint, twice as long as broad. The 

 secondaries have a distinct circular spot of pearly white, narrowly 

 annulated with black, situated at the base, between the first branches 

 of the subcostal nervure; an indistinct mesial band, often obsolete, of 

 the same color as the apex of the wing. Expanse of wlno-s 1.4 inch. 



This species is closely allied to H. punctella Grote and Rob. ; it 

 differs from it in the three subapical spots, which increase in size 

 towards the costa, and have no pale spots surrounding them on the 

 under surface; in possessing a large pale spot on the under surfice of 

 the primaries beyond the cell, and a white dot at the base of the 

 under surface of the secondaries ; possibly the black dash of the 6 

 also differs in the two species. 



This fine species has been taken by Mr. Sanborn at Quincy and 

 Dorchester, Mass.

 spots; fringe dusky, blackish towards base. 



Primaries with a large irregular spot in the cell; it consists, first, of 

 a square spot which occupies the Avhole width of the cell, and has its 

 outer limit at the second divarication of the median nervule; startincr 

 from a little beyond the lower inner angle of the square spot, where 

 it is divided by the median nervure, it does not reach the subcostal 

 nervure, and is obliquely truncated or rounded; there is a subapical 

 row of spots; the three subcostal ones are wedge-shaped, their ai^ices 

 pointing inwards; the two between the suocostal and median ner- 

 vures are smaller than the rest, sublunate, and situated so much 

 further outwards that their inner border runs parallel to the outer
