164 MR. A. G. BUTLER ON [Feb. 18, 



differing from both genera in its enormous sieve-like antennae. Type 

 Attaeus hercules, Misk. 



COSCINOCERA OMPHALE, n. Sp.' * 



Ferruginous ; wings crossed near the base by a rusty whitish stripe, 

 oblique, hisinuated and angulated upon the median vein in the an- 

 terior wings, and nearly straight in the posterior wings ; a second 

 stripe of tiie same colour across the external third, parallel to the 

 outer border, and slightly incurved towards the costa of anterior 

 wings, bounded internally by a dark ferruginous or mahogany-brown 

 stripe ; outer border dull ochraceous brown ; a large ocellus closing 

 each discoidal cell, the centre formed by a white-edged triangular 

 hyaline spot, with broad black-edged dull ochraceous iris : primaries 

 with the ocellus elongated and subtriangular ; apical area pinky 

 white, bordered and longitudinally streaked with lake-red : secon- 

 daries with the ocellus almost circular : head and collar testaceous, 

 the latter partially bordered behind with white ; base of abdomen 

 white. Wings below much paler and of a sordid clay-colour, brownish 

 towards the outer border, which is testaceous ; stripe across the 

 basal area obsolete ; discal stripe more distinct and whiter than above, 

 with dark brown internal border ; ocelli rather smaller than above, 

 and with less vivid black margin : fore wings with the apical area 

 less distinctly clouded with white ; hind wings white at the base, 

 the abdominal and external areas broadly, but not abruptly, darker 

 than the fore wings : body testaceous, coxae tufted with white hair ; 

 venter with lateral white line and transverse preanal white belt. 

 Expanse of wing 9 inches 7 lines. 



This species may be distinguished from C. hercules, Miskin (Trans. 

 Ent. Soc. 18/6, p. 7), by the redder and not black-bordered pale 

 stripes of the upper surface, the ochraceous irides to the ocelli, and 

 the more vivid instead of paler discal stripe of the under surface. 

 Comparison with the Australian species will probably reveal other 

 differences which are not apparent in Mr. Miskin's description. 



CossiD^. 

 Zeuzera sign ATA, Walker, Lep. Het. vii. p. 1537, n. 19. 



A single example of what seems to be a slight variety of this 

 Indian species ; unfortunately the type of Z. signata is much dis- 

 coloured and somewhat worn. When more specimens are obtained 

 from both localities, it will be possible to determine whether or not 

 the differences which do exist are constant ; they are principally 

 confined to the costal border of the fore wings. 



Ophiderid.?;. 



Ophideres dioscore.e, Fabricius, Sp. Ins. ii. p. 212, n. 15. 



A worn, but unusually dark example of this form. 



* The type is unfortunately somewhat damagpcl, and has only the commence- 

 ment of the tails. A rather larger example received since the reading of this 

 paper has tails 3 inches 9 lines in length, and less spatulate in character than 

 the species of Argeina.
