lies in the structure of vein 12 of the hindwings; and, as already explained, I do 

 not consider the two families to be of allied origin. 



1. Forewings with 11 connected by a bar with 9, 10 towards apex 1. Cotana. 

 Forewings with 11 free 2. Eupterote. 



Gen. 1. C O T A N A. 



Cotama, Wlk., Cat. Brit. Mus., xxxii., p. 548. 



Frenulum and retinaculum present, but rather weakly developed. Posterior 

 tibiae without median spurs. Forewings with eell very short (about one-fourth) ; 

 2 from middle, 3 and 4 separate, 5 from upper angle, 6, 7, 8, 9, 10 stalked, 10 

 separating near margin, 11 connected by a bar with 9, 10 at two-thirds of wing, 

 and thence closely approximated. Hindwings with cell very short (less than one- 

 fourth), 5 from upper angle of cell, connate or stalked with 6, 7, 8 diverging 

 from eell near base. 



A peculiar and isolated genus; the structure of vein 11 of the forewLng 

 is unique. The sexes differ so remarkably that it is impossible to correlate them 

 Ijy mere inspection. 



IVpe, C. rubrescens Wlk. from New Guinea. 



1. COTANA SERRANOTATA.

 cydas calliloma, Turn., Trans. Roy. Soc. S. Aust., 1903, p. 23. 



c?. 46-50 mm. Head, palpi, and thorax dark-ochreous-brown. Antennae 

 oeln-eous-brown ; pectinations in c? 6. Abdomen and legs orange. Forewings 

 triangular, costa straight to beyond middle, thence gently arched, apex rounded 

 termen slightly bowed, slightly oblique; pale ochreous-brown, towards base suf- 

 fused with whitish-ochreous ; sometimes a pale-centred discal dot at one-fourth; 

 a brown line from mid-costa to dorsum before middle, slightly sinuate, variable 

 in breadth; a more oblique, faintly-marked, outwardly-bowed line from three- 

 iourths costa to dorsum beyond middle, succeeded by two slender, finely crenulate 

 lines; cilia brownish. Hindwings with termen rounded, orange-ochreous ; some- 

 times with several faint, transverse, fuscous lines, of which the subterminal is 

 crenulate; cilia brownish. 



?. 60-75 mm. This sex has been sufaciently described.

According to Lord Rothschild not from New Guinea. 



2. COTANA NEURIX.A, n.Sp. 



vevpims, With nervures. 



5. 62 mm. Head and thorax pale ochreous-brown. Palpi very short; fus- 

 cous. Antennae in ? simple, apical third very shortly pectinate; fuscous, towards 

 base pale ochreous-brown. Abdomen reddish-brown; apical segment grey-whitish. 

 Legs reddish-brown; tibiae and tarsi fuscous. Forewings broadly triangular, 

 costa moderately arched, apex rounded, tei-men bowed, oblique; fuscous-brown; 

 •\-eins slenderly outlined with pale-ochreous ; basal third partly covered with pale 

 ochreous-brown hairs, which form a broad costal streak extending to middle, 

 dilated at extremity; a circular pale-ochreous spot in cell beneath one-fourth 

 costa; a coarse, strongly-dentate, pale-ochreous, subterminal line; slightly darker 

 transverse shades across disc before middle, and along termen; cilia ochreous.
