PSYOHINAE. 415 



Speyer noted the second of these groups as typical Oreopsyche, i.e., 

 the group containing angustella, H.-S. (atra, Esp.). 



The following year (1866) Eambur divided (Lep. Andalousie, p. 307) 

 this same (atra) group (to which as a whole he applied the name 

 Ptilocepliala, citing atra, Esp., as the type) into three sections : 



(1) Atra., Esp., sicheliella, BrcL, hirsutella, S.V., muscella, Hb., plumifera, 

 Ochs., mediterranea (Led., massilialella, BrcL). 



(2) Tabanella, Brd., kahri, Led. 



(3) Albida, Esp., plumosella, Rbr., malvinella, Mill. 



This third group Rambur names (Ibid, p. 310) Hyalina, whilst plumi- 

 strella is given as the type of Scioptera. 



In 1879 Standfuss divided (Zeits. Ent. Bred., n.s., vol. vii., p. 41) the 

 Oreopsychids into four sections (retaining Speyer's name Oreopsyche), 

 as follows : 



(1) Tenella, Spr. 



(2) Plumistrella, Hb. 



(3) Schiffermilleri, Staud., pyrenaella, H.-S. (tabanivicinella, Brd.), vcsubiella, 

 Mill., atra, Esp., muscella, Hb., fulminella, Mill., mediterranea, Led., gondebautella, 

 Mill, (sicheliella, /Brd.), plumifera, Ochs. (siculella, Brd.), kahri, Led. 



(4) Silphella, Mill., leschenaulti, Staud., malvinella, Mill., albida, Esp. 



All these groups except the tenella group have already been placed in 

 different genera. Standfuss diagnoses this as : 



Antennas J longitudinis alarum attingentes ; plumulis longis. Alae pellucidaa 

 vel opacse, pro corpore maxima, pilis obtectse et circumdatse. Corpus gracillimum, 

 corpore affinium rarius lanuginosum — tenella, Spr. 



It appears quite clear that tenella and zermattensis are further removed 

 from Scioptera plumistrella than is the latter from Leptopterix schiffer- 

 milleri,. and as these groups have all been adequately diagnosed by 

 Standfuss we would call the tenella section Standfussia, and cite 

 tenella as the type. 



Before discussing the synonymy of the above divisions, we may 

 state the suspicion that the tribe Oreopsychidi should be called the Phala- 

 cropterygidi, since this appears to be the oldest group name for the 

 tribe. Hiibner about 1825 (vide, ante p. 265) suggested Phalacropterices 

 as a group name, consisting of the genus Phalacropterix, with vitrella 

 (albida), fucella (apiformis), and muscella. This genus he diagnosed 

 as : " Wings almost naked and transparent as far as the margin." It is 

 pretty clear then that Hiibner intended this name for the transparent- 

 winged group (Oreopsychidi), and although one may call apiformis 

 moderately transparent, the description applies much more strongly to 

 albida and muscella, which are almost scaleless over the greater part of 

 the wings, and it must be considered as particularly referring thereto. 

 There can be no doubt that Phalacropterix is heterotypical, for apiformis 

 is an Empedopsychid, and Rambur, in 1866, proposed (Cat. And., p. 

 301) for this species and graslinella the name of Arctus, whilst, as we 

 have already stated, he further erected (ibid, p. 310) the genus Hyalina 

 for albida, its var. plumosella, and malvinella, so that this leaves 

 muscella (an Oreopsychid) the residuary type of Phalacropterix, Hb. 



One other synonymic difficulty remains. Hiibner's genus Leptop- 

 terix was erected (vide, ante, p. 265) for viciella and schiffermilleri, Staud. 

 ( — Jtirsutella, S.V. nee Hb.) ; but these are heterotypical and we shall 

 show a little later that viciella is the type of Psyche, Schrk., so that 

 schiffermilleri becomes the residuary type of Leptopterix. This species 

 Heylaerts groups with plumistrella, Hb., and tenella, Spr., in the genus
