162 Lord Walsingham's revision of the 



luteous or dull reddish brown, with lutcous or yellow along the fold 

 and inner margin ; a spot on the disc and one on the middle of the 

 nervules of the same hue, with a dark brown spot on the fold 

 beneath the median vein, most frequently semicircular, with a 

 short dark brown streak at the base on the submedian vein, and 

 another parallel to it beneath the median. The anterior margin 

 striated from the costa with dark brown, with a subterminal row 

 of dark brown spots above the branches of the median vein, and 

 the ends of the nervules dotted with the same hue; cilia pale 

 yellowish brown. Hind wings brownish yellow, cilia the same. 

 Exp. al. 12 to 18 lines (= 25| — 38 mm). Male and female alike. 

 Texas." 



Now, so far as the antennas and palpi are concerned, Clemens' 

 observation " male and female alike " is certainly misleading. The 

 antennae of the male are stout and deeply serrated, " with the ends 

 of the articles finely ciliated," as described by him. Those of the 

 female are simple. The lateral claspers are elongate, spoon- 

 shaped, scarcely dilated, and evenly rounded. The uncus double, 

 angulated above, and bent over at right angles, with a conspicuous 

 thickening at the angle. 



Mr. Grote, in describing his agrotipennella, points out 

 that this differs from popeanella as follows : — " A. popea- 

 nella disagrees with A. agrotipennella by, among other 

 characters, its being described as luteous along the 

 inner margin." 



An examination of my extensive series shows that 

 both varieties belong to the same species. The anal 

 appendages do not differ, and intermediate variations of 

 colouring are noticeable. There can be no doubt that 

 they differ only in the extension of the pale colour of 

 the fold in the direction of the dorsal margin. In 

 confirmation of this view it is noticeable that both forms 

 are labelled in Zeller's collection " Anaphora scardina, 

 Z."; the typical form of agrotipennella received from 

 Grote, as well as from Boll from Texas, being placed in 

 the same series, and evidently regarded by Zeller as 

 synonymous. 



I have two specimens compared with what was sup- 

 posed to be the type of popeanella at Philadelphia; a 

 third specimen bred by Miss Murtfeldt, and received 

 from her under the the name agrotipennella, Gr. ; one 

 specimen from Mons. Ragonot from Boll's collection and 

 labelled " scardina, Texas " ; several similar specimens
