much so as to be only distinguished from autumnata by (he absence of :i third 

 pair of abdominal legs, there being one exceedingly rare exception in this 



last character. It is possible that the two species were al firsl seasonal 

 dimorphs. A. autumnata, however, according In .Air. Mann (Proc. Host. Soc. 

 Nat. Bist., xv, 384, L873), does sometimes appear in the spring, as will he seen 

 by the following ([notation: "Of 16 dated specimens of the male in my col- 

 lection, 12 were taken in ( >ctober or November, and 4 in March or April. The 

 two spring specimens in my collection now are among the most, strongly 

 characterized I have. Of several hundred females in my collection, .four were 

 taken in April and the rest in November." 



Mr. Mann describes, in the Proc. Bost. Soc. Nat. Hist., xvi, a female, of 

 this species, which had two aborted wings and pectinated antennae. 



As this species was wrongly called A. vernata Peck by Harris: and as 

 Harris's pometaria, as shown by Mr. Mann, is Peck's vernata, it clearly follows 

 that a new name must In- proposed for Harris's "vernata '; I therefore propose 

 autumnata, as it is on the whole an autumnal species.

20 <f . — Pale ash, body a little darker; head with often a slight, trans- 

 verse, darker hair-line across the trout just below the antennae. Fore wings 

 crossed by three interrupted black lines, consisting of costal and venular black 

 dots. Inner line much curved, on the costa forming an oblique black spot ; 

 the second line varying in position, being near the middle of the wing or on 

 the inner third, and much nearer the inner line: it is straight, oblique on the 

 costa, and a little sinuate ; third line oblique, not sinuate, and deflected on 

 the costa. A slender, black, apical, oblique streak, from which runs a zigzag. 

 obscure, broad, whitish line to the inner edge; this line is much less distinct

 in tin' correct genus, Ins name should follow the scientific name.
