238 Some apparently new Species and Forms of Noctuidae 



postmedial area shows considerable differences and the antemedial black 

 patch is also somewhat different. 



56. Rivula manuselensis sp. nov. 



? , 21 mm. 



Head, body and palpus above whitish ; palpus on outer side and 

 beneath, pectus, legs and abdomen beneath ochreous-brown. 



Fore wing whitish, tinged with ochreous-brown (especially at distal 

 margin). Middle of wing much rubbed but showing traces of brown 

 subbasal, antemedial and medial lines, the antemedial apparently evenly 

 excurved from about two-sevenths costa to two-sevenths hindmargin, 

 the medial excurved from middle of costa to cell, thence oblique or 

 slightly incurved to about two-fifths hindmargin ; a black discal dot at 

 each angle of cell ; postmedial line double, macular very oblique from 

 costa near origin of medial line to SC 5 near termen, thence inwardly 

 oblique to hindmargin at about five-sevenths (apparently slightly angled 

 in at fold, but worn) ; a row of interneural black and white dots close 

 to termen ; fringe white thickly striated with brown and with a brown 

 line near base. 



Hind wing smoky-brown, slightly darkened at termen, with a fine 

 pale line at base of fringe. 



Fore wing beneath brown, paler on posterior third, the veins, costa 

 and termen tinged with ochreous. Hind wing white, the veins towards 

 costa and termen tinged with ochreous ; some brown irroration at costa 

 and termen, a dark discal spot and curved postmedial line. 



Manusela, 6,000 feet, October to December, 1919, one 2 . 



Seems nearest to aroa Beth.-Bak., but has the postmedial line 

 darker and less curved behind SC 5 . 



Agrees in structure with B. sericealis Schiff. except in E 2 of the 

 hind wing, which arises almost from angle of cell instead of from 

 before angle, as in sericealis ; E 4 and M 1 of hind wing stalked to about 

 one-third. 



57. Othreis cajeta Cr. talboti subsp. nov. 



$ ? , 98—106 mm. 



Differs from cajeta cajeta Cr. chiefly on the hind wing, where the 

 black border is incurved from costa to E 1 , but scarcely angled on E 1 (as 

 in cajeta cajeta). On the underside this difference is more noticeable
