more distinct. Middle line making a righl angle opposite the discal ring, 

 broad on the costa, below the median vein parallel with the outer line, and 

 nut touching it. Outer (third) line very sinuous, with a large rectangular 

 bend opposite the discal ring; the line curves inward to the poinl of the 

 angle, which is either square and subdentate, or rounded ; another prominent 

 bend just below the third median venule, where the line is deeply curved 

 inward. The line usually bordered externally with pale chocolate-brown 

 (though not always). The usual zigzag, submarginal, white line inclosed in 

 a black shade, or both partially obsolete. Marginal row of dots as usual. 

 Hind wings with a broad, black, inner line, usually double and often touching, 

 and in one case inclosing the discal ringlet. Outer line with a greal subacute 

 angle opposite the discal dot, and thence following a deep regular curve to 

 near the anal angle. Beyond as in the fore wings. Abdomen with a black 

 line at base, beyond not spotted. Beneath pale, with the discal dots very 

 large and diffuse ; a submarginal, broad, dusky shade, sometimes not extending 

 beyond the middle of the winy. The outer line is faintly reproduced.

 from the large pale race. 



This common species seems to be divided into two races, one smaller 

 and darker, with the antennae more broadly pectinated, while the outer line 

 on the hind wing is less angulated, but it is difficult to draw a line between 

 them. The species may at once lie known by the very sinuate outer line on 

 the fore wings, and the greal angle in the corresponding line on the hind 

 wings. 



A striking variety received from Mr. Meske has darker wider lines than 

 usual, the inner line on the bind wings double and very heavy and broad, and 

 inclosing the discal ringlet, while the outer line is but slightly angulated. 



Ltnru. — Head of larva smooth and rounded, much as usual. Larva 

 dull red, on wild cherry dune 26; imago July 8. Pupated June 25; imago 

 appeared duly 12. brown, of the usual shape and color ( Saunders). The 

 moth reared l>\ Mi Saunders belonged to the small race.
