A. G-. Butler giebt in seinem Aufsatz On the Moths of the fa- 

 mily Urapterygidae . . . synoptische Diagnosen der Gattungen dieser 

 „Familie", nämlich Urapteryx, Tristrophis n. g. („form of Urapt. ma- 

 culicundaria , but at once distinguishable from typical Urapt. by the 

 neuration of the secondaries, the siibcostal branches being emitted from a 

 Short footstalk, and second and third median branches separated at their 

 origins, instead of being emitted from the same paint" S. 199), Gonor- 

 thus („difFers from Urapteryx in the form of the wings-the primarics 

 having an acute apex and straight outer margin; the sec. with rect an- 

 gular outer margin, the angle being acutely produccd but not preceded 

 by a Short angle as in the 2 foregoing genera; discocellular of sec. 

 almost straight and transverse" S. 200), Ilipula, Sirinopteryx („allicd 

 to Gonorthus and Tristrophis, with the form of wings nearly as in the 

 former, but the neuration of the latter; the antennae of the male thickened 

 but not pectinated"), Gonogala, Nepheloleuca („form of Gonorthus, and 

 with very similar neuration, excepting that the subcostal branches of the 

 sec. are not emitted quite at the same point, that the 2. and 3. median 

 branches are also separated by a short space at their origins, and that 

 the radial is very oblique and subangulated towards the anterior angle of 

 the cell : antennae very different, not pectinated in the male, but with fine 

 Short cilia along the anterior margin" S. 201), Thinopteryx („Prim. 

 triangulär, with acute prominent apex; second subcostal with its 3 branches 

 emitted before the end of the cell; lower radial emitted from the centre 

 of the discocellulars; discocellulars forming a concave transverse line; 

 second and median branches well separated at their origins: secondaries 

 with two distinct angles — ... the second forming a short tail; . . sub- 

 costal and second and third medians separate at their origins; the disco- 

 cellular oblique and slightly concave ; antennae ciliated not pectinated" 

 S. 202), Xeropteryx (S. 203), Aeschropteryx („form of Gonorthus: 

 neuration nearly as in Urapteryx, but the antennae of the male simple" 

 S. 204). Die Typen der neuen Gattungen sind Tristrophis (Urapt.) Vc- 

 neris Bull., Gonorthus (Urapt.) fiavifimbria Walk., Sirinopteryx (Urapt.) 

 rufivinctata Walk. , Nepheloleuca (Phalaena) politia Cram. , Thinopteryx 

 (Urapt.) crocopterata Kollar, Xeropteryx (Urapt.) columbicola Walk., 

 Aeschropteryx (Chaerodes) tetragonata Gic^n^e. Von Thinopteryx werden 

 ausserdem die n. A. striolata (Japan) S. 202 und nebuhsa (Silhet) S. 203, 

 von Xeropterj-x simplicior (Sarawak) S. 204 beschrieben. Auf der bei- 

 gefügten Tafel ist Flügelgeäder und männlicher Fühler abgebildet, und 

 zwar Urapteryx 1,2, Tristrophis 3,4, Xeropterj-x 5,6, Aeschropteryx 

 7, 8, Gonorthus 9, 10, Nepheloleuca 11, 12, Thinopteryx 13, 14, Sisino-
