252 Mr. Warren on the Pyralidina collected 



somewhat produced. Antennse (of <?) strongly pectinated, the 

 pectinations themselves swollen towards their apex, and ending 

 each in a fine bristle ; all the pectinations so finely and closely 

 ciliated as to appear almost membranous. Palpi laterally com- 

 pressed, ascending, suboblique, twice as long as the head ; third 

 joint half the second, the tips of both blunt ; tongue hairy; maxil- 

 lary palpi invisible ; forehead hairy ; patagia well-developed, 

 extending beyond the thorax ; legs with the fore and middle 

 femora (and probably the hind ones also) hairy. 



33. Triommatodes plumosa, n. s. 

 Fore wing dull ochreous, with indications of three irregular 

 curved transverse lines ; the first near the base ; the second before 

 the middle, followed between the subcostal and median veins by a 

 black patch; the third beyond the middle, preceded and followed 

 below the costa by blackish shading, and followed only by a similar 

 shading towards the anal angle. Hind wing with this dark blotch 

 at the anal angle reproduced, and with two curved bands. Under 

 side ochreous, with central dark dot. Head, face, and thorax 

 ochreous ; abdomen pale ochreous, with blackish anal tuft. Ex- 

 panse of wings, 40 mm. 



One (? , from Gepatiny, E. Purus, Sept. 29th, 1874. 

 The single specimen is in poor condition, and the 

 markings can only be made out indistinctly. 



Atopomorpha, n. g. 

 Fore wing very long and nan-ow ; costa at base nearly straight, 

 with a shallow concavity in the middle, and very convex at the 

 apex ; hind margin very oblique, sinuous, the upper half convex, 

 the lower concave ; the anal angle somewhat square. Hind wing 

 broad ; the costa strong, arched at the base and sinuous, like the 

 fore wing, but more exaggerated ; hind margin with a prominent 

 blunt projection occupying the upper two-thirds, then sinuous to 

 the anal angle, which is rather prominent. Abdomen very long 

 and thin ; the head with its organs is damaged ; hind tibiae with 

 two pairs of spurs, the inner of each three times as long as the 

 outer. Neuration : Fore wing, cell reaching quite three-fifths of 

 the wing, its basal half underneath beset with hairs ; first median 

 branch from the centre of the cell ; the second, third, and lower 

 radial from the lower end of the cell ; the third slightly arched, the 

 radial considerably ; upper radial from below the upper angle of 

 cell ; first subcostal branch from the middle ; second just before the 

 end; third, fourth, and fifth stalked, the fifth soon leaving the
