PSYCHINAE. 417 



Gymna, Kbr., and Stenophanes, Heyl. These he terms subgenera 

 (making them sections of the genus Psyche, Schrank), and defines 

 them as follows : 



Antennes bipeetinees jusqu 'au sommet, a barbules plus ou 

 moins longues. Les tibias anterieurs n'ont pas une 

 epine tibiale . . . . . . . . . . . . . . Psyche, Schrank. 



(a) Les ailes anterieures tres larges et a angles tres 



arrondis. Les barbules des antennes assez longues Megalophanes, Heyl. 

 (/3) Les ailes anterieures larges, mais pourtant plus 



allongees. Les barbules des antennes tres courtes Gymna, Rbr. 

 (7) Lee ailes anterieures allongees, mais assez etroites. 

 Les barbules des antennes plus ou moins epaissies 

 a leur sommet . . . . . . . . . . Stenophanes, Heyl. 



The first of these subdivisions, Megalophanes, Heyl., includes among 

 other species, vicielia, S.V., the species that has since been determined 

 by Kirby as the type of Schrank's Psyche, a heterotypical genus con- 

 taining — graminiim, viciae ( = vicielia), carpini, agrostidis ( = atra, teste 

 Heylaerts) , lichenum, querciis (xylophthorum, Pallas) , and primi — of which 

 Schrank did not know the two last-named in nature. In 1809, 

 Latreille restricted (Gen. Crust., iv., p. 219) the genus Psyche to 

 hieracii (=unicolor), vicielia, and muscella (by name, although he adds 

 "etc."), but Hubner had already in 1806 (Tent., p. 2) fixed unicolor as 

 the type of Canephora, so that the type of Psyche was restricted to 

 vicielia or muscella. Of these muscella is Oreopsychid, and, moreover, is 

 not included in the genus by Schrank, besides being as we have already 

 shown (ante, p. 415) the type of Phalacropterix, so that this left vicielia 

 the residuary type of Psyche. Unless, therefore, Megalophanes, Heyl., be 

 heterotypical, this genus falls as a synonym of Psyche, Schrank, whilst 

 Gymna, Ebr., falls as a synonym of Sterrhopterix, Hb., for there can 

 be no doubt whatever that Sterrhopterix is the proper generic title for 

 hirsutella, Hb. At the same time, as we have already stated (ante, p. 

 415), Eambur created the genus Arctus for apiformis and graslinella, 

 two of the typical species of Heylaerts' Stenophanes. This being so, the 

 latter genus falls before Arctus, Kbr. Hence it would appear that, 

 if Heylaerts' divisions (supra) of the Psychidi be sound, the 

 proper generic appellations would be Psyche, Sterrhopterix, and Arctus 

 respectively, Psyche replacing Megalophanes, Sterrhopterix replacing 

 Gymna, and Arctus replacing Stenophanes. 



The genus Psyche of Wallengren, which he diagnoses as " Ake 

 diaphanae pilosuhe," is quite heterotypical, for he includes therein not 

 only vicielia and stetincnsis, which belong to Psyche, but Stenophanes 

 graslinella, Acanthopsyche opacella, and Pachythelia villosella, whilst 

 Sterrhopterix hirsutella (fusea) is separated on account of the " costa 

 subcostalis tota libera, nee cum costa mediana per costam transversam 

 connexa," under the name Tricliopsyche. 



Like the Oreopsychidi, the Psychidi contain species with scaled 

 antennules, bipectinated antenna, the anterior tibiae without spurs, and 

 both tribes also contain sections comprised of robust and slenderly 

 built species respectively (ante, p. 274). In the Psychidi the species of 

 Stenophanes are robust with somewhat narrow wings, whilst those of 

 P.syc/tr and Sterrhopterix are more slenderly built, have wide and ample 

 wings, the former with very long, the latter with very short, antennal 

 pectinations. 



We have no Oreopsychids in Britain, and of the true Psychids only
