348 NOVITATES ZOOLOGICAE XXII. 191.'). 



Bitye, Ja River, Cameroons, 200U ft., September — November 1911. Type in 

 coll. Rothschild. 



A good deal like Neostega jlavigutta Warr. {Noc. Zool. k. 27G) except in shape 

 and antennal structure. Whether these should override the noteworthy venatioual 

 approach to that genus remains somewhat doubtful. 



77. Peridela amica sp. iiov. 



c?, 29 mm. Face deep fuscous, narrowly ochreous below. Palpns deep fuscous, 

 mixed with ochreous beneath. Vertex and antennal shaft bright ochreons, spotted 

 with fuscous ; pectinations very long, recalling Oxijfidonia or Obolcoln. Thorax 

 deep fuscous, mixed with ochreous in front. Legs fuscous, the foreleg darkest bnt 

 with the femur spotted with ochreons, and boMi femur and tibia becoming ochreons 

 on outer side ; hindtibia not dilated. Abdomen fuscous. 



Forewing with apex minutely produced, terraen bent at R^ ; 80'"^ stalked, 

 separating opposite base of SC ; fovea present ; violet-grey, irrorated with fnscous ; 

 costal margin ochreons spotted with fuscous, underlined with ferruginous along SC ; 

 the other veins tinged in places with ochreous or ferruginous ; lines slender, whitish 

 yellow ; antemedian vertical from hindmargin beyond one-third, obsolescent 

 anteriorly to M ; edged proximally with ferruginous ; postmedian almost straight, 

 from beyond three-fonrths costa to beyond two-thirds liindmargiu, edged distally 

 with ferruginous ; discal dot small, black ; terminal line fine, ochreous ; fringe 

 blackish in proximal half, ochreous in distal, with blackish spots opposite the veins. 



Ilindwing snbcrenulate anteriorly, a tooth (about rectangular) at R^; concolorons 



with forewing, except costal margin ; antemedian line represented only by a vague 

 ferruginous shade; postmedian as on forewing (much farther from termen in 

 middle, on account of the wing-shape) ; discal dot, terminal line and fringe as 

 on forewing. 



Underside without antemedian line, the ferruginous shading distally to the 

 postmedian weaker bnt more diffused. 



Bitye, Ja River, Cameroons, 2000 ft., September — November 1911. Type in 

 coll. Rothschild. 



A closely similar species (or, as I am inclined to believe, a highly remarkable 

 aberration) is also represented by a single cf with the same data, unfortunately 

 rather rubbed. Pale ochraceous instead of violet-grey, the fnscous irroration coarser 

 but more irregular, especially on hindwiug, where almost clear bands are left 

 between cell-dot and postmedian line and again at termen, while the proximal 

 part of hindwing is heavily marked ; antemedian shade of hindwing thickened and 

 darkened, crossing the cell-dot ; postmedian line of both wings nearer termen, on 

 forewing slightly excurved behind middle and incurved posteriorly, on hindwing 

 nearly parallel with termen, more inbent between radials. 



78. Osteodes procidata eritreensis subsp. nov. 



Forewing above with the dark border strong, rather broader than in most 

 forms of procidata G\\Qi\.{Spec. G(fn. Lcp. x. 177), very sharply defined proximally, 

 the pale suba])ical streak widened in its proximal part, so as to occupy more than 

 half the width between R' and SC'' ; a well-marked costal spot (rarely noticeable 

 in the other forms) proximally to the dark border. Ilindwing with rather
