 = * ELACHISTA (Tr. p.) Z.. Stn., Stgr-Rbl., etc. 



Type Phalaena Tinea argentella Cl. (Wstwcl. 1840). 



APHELOSETIA Stph. 111. Br. Ent. Haust. IV. 287 (1834); "Wstwd. 



Syn. Gn. Br. Ins. 112-3 (1840). 



ELACHISTA Tr. (c. ELACHISTA) Z. Isis 1839. 211, 212-3. 



When describing Elachista, Treitschke [Schm. Eur. IX. (2). 177 

 (1833)] wrote as part of his generic diagnosis : ' ; Die liaupeii 

 leben auf der Unterseite der Baumblatter oder minirend zwischen. 

 deii Hauten derselben. Sie verpuppen sich in festen Hiilsen." 

 This restricted the possible type to species with such larval habits 

 (i. e. Bucculatrix Z. and Phyllonorycter Hb.) with whose life- 

 history Treitschke was acquainted, and rendered it impossible 

 for any of the grass-mining species (Elachista Auct.) to be 

 regarded as a potential type. Treitschke quotes the life-history 

 of Buccidatrix frangulella Goze and Phyllonorycter (Lithocolletis) 

 tremulae Z. from Fischer von Roslerstamm (in litt.), but he was 

 personally acquainted with the larvae of ulmifoliella .Hb. and 

 Uancardella (F., mespilella Hb. 272) Tr. Elachista Tr. must there- 

 fore sink as a synonym of Phyllonorycter Hb., and vlmifoliella 

 Hb. should be taken as the type. Duponchel [HN. Lp. Fr. 

 XI. 25, 499-502 no. 30 (1836)] cited complanella Hb. as the type 

 of Elachista Tr., but Treitschke was unacquainted with the larva 

 of complanella, and this species is not indicated as specially 

 typical. Zeller's restriction to the grass-feeding species is also 

 invalid for the same reason. 



79. (3994-1) APHELOSETIA HYPOLEUCA, sp. n. 

 (Plate LIL fig. 11.) 



Antennae fuscous, the basal joint pale ochreous. Palpi whitish 

 ochreous. Head and Thorax whitish ochreous, the latter faintly 

 shaded with fawn-grey. Forewings pale oehreous (whitish ochreous 

 if worn), sprinkled and suffused with fawn-brown, especially 

 above the fold beyond the middle, with some deeper brownish 

 fuscous shades, notably along the costa and about the tornus ; 

 three black spots, one below the costa at two- thirds ; a smaller 

 one, a little beyond and below it, about the end of the cell ; 

 a third, more conspicuous, on the fold at about half the wing- 

 length ; a strong blackish shade-line runs along the middle of the 

 brownish ochreous cilia. Exp. al. 8-9'5 mm. Hindwings rather 

 dark leaden grey ; cilia tawny greyish. Abdomen grey, anal tuft 

 ochreous. Legs pale brownish ochreous, shaded with fuscous 

 externally.
