In redescription of celiana Robinson, McDunnough (1934, p. 302) 

 wrote that the red-bro\vn tufting of the thorax is apparently lacking 

 in hastiana. The present author had at hand many specimens of 

 hastiana, especially from Europe, in which a red-browm tuft was well 

 developed. 



Types. — Lectotype of hastiana (selected by Sheldon, 1923). figured 

 by Clerck, 1759, Icones insectorum, pi. 2, fig. 7. Holotype of pid- 

 verosana, female (without abdomen), St. Martins Falls, Albany River, 

 Hudsons Bay, Canada, 1844 (Barnston), BM. Walker erroneously 

 indicated this specimen as male.

10 and 14. New synonym. 



Through the kindness of Dr. Pierre E. L. Viette (Museum National 

 d'Histoire NatureUe, Paris), the present author had an opportunity to 

 study Peronea caryosphena, described by E. Meyrick from Greenland. 

 The examined series consisted of two males and two females taken in 

 Greenland in 1949 and identified by Dr. Viette. The moths vary 

 considerably, and some have almost unicolorous gray forewings. 

 The antemedian band and groups of raised scales are typical of fresh 

 specimens which, in addition, have the forewings slightly powdered 

 with pale-grayish scales. In the genitalia, the specimens from 

 Greenland do not differ from Peronea walkerana described by J. 

 McDunnough from Ontario and Quebec. 



The male genitalia of walkerana resemble those of Acleris hastiana 

 (Linne), but they differ from them in the shape of some parts. The 

 cristae of the tegumen of walkerana are strongly reduced, the anal 

 spine of the gnathos is stronger than that of hastiana, and the angle 

 before half of the sacculus is more pointed. The length of the cornuti 

 and the shape of the socii are rather inconstant in both of these species. 

 The female genitalia give a solid basis for distinguishing walkerana 

 and hastiana. 



Specimens examined. — One female paratype of walkerana (geni- 

 talia on slide P. 43a), Aylmer, Quebec, Apr. 25, 1924 (C. H. Curran), 

 USNM. Two males and two females (genitalia on slides 1-Obr. and 

 2-Obr.), western Greenland, 69° 45' E., Aug. 22-25, 1949 (Mission 

 P. E. Victor H. de Lesse, 1949), in the Museum National d'Histoire 

 NatureUe, Paris.
