more slender and more curved than the left. A comparison of the 

 figures will better bring out the differences than any description. 



In the female the indentations on the upper surface of the anal 

 segment are well marked. Beneath, the lobes of the anal plate are 

 large and well marked, the left being conspicuously larger than the 

 right. The opening to the copulatory pouch is at the upper inner 

 angle of the right plate and is all from the upper margin, differing 

 markedly in position from that of obliqua, to which the species has 

 the greatest superficial resemblance. 



This species is listed in our catalogues as a synonym of Pseudan- 

 thracia coracias Guenee, a name of much later date, and Walker is 

 responsible for the original identification. Mr. Grote, while he fol- 

 lowed the reference, doubted its correctness, and I made no changes 

 from lack of better information in 1893. In 1891 I found that the 

 squammularis of Walker as represented in the British museum was 

 Ypsia undularis, a small, flown example of which might readily be 

 mistaken for coracias as figured by Guenee. 



Reference to Drury's figure indicates a species the original of 

 which could not possibly have been the coracias of Guenee, although 

 neither does it represent at all accurately anything else in our fauna. 

 But the description helps : 



Alis cinereis, antice fascia irregulari centrali ferruginea, lineis duabus 

 externa cincta, posticis faseiis duabus obscuris. 



The expanse is given as 1.75 inches and the habitat as New York, 

 May 11. 



In the Westwood edition the English description is yet more spe- 

 cific: 



Upper side. — Tbe antenna? are brown, like fine tbreads. Tbe colors on the 

 anterior wings are divided by a strong bar of chocolate, running cross the wing 

 near the middle, from the anterior to the posterior edges. This softens into a 

 deep slate color, covering that part of the wings down to tbe external edges. 

 The part next tbe shoulders is of a light asben or pearl gray color whereon are 

 two small black spots or stripes, situated near the anterior edge. On the dark 

 part near the lower corner run two small black irregular lines from the pos- 

 terior edge; one running cross the wing, the other only half across. The pos- 

 terior wings are of a lightish brown, having two bars of deep brown • (almost 

 black) rising from the abdominal edge, and crossing the wing upward, grow 

 broader and fainter as they approach the middle and anterior edge. 



Underside is of a faint russet color, having little or no markings thereon. All 

 the wings are slightly dentated. 



This figure and description could apply to nothing in our fauna 

 save obliqua or the form with which I identify it here. It is too 

 sharply marked for obliqua, and on the whole the description fits 

 excellently well to the specimens now before me. It restores Drury's 

 name without displacing any other now in use.
