168 NOVITATBS ZOOLOGICAE XXIII. 1916. 



curved ; postmedian nearly straight, very slightly oblique, 3 or 4 mm. from termen 

 anteriorly, 4 or 5 mm. posteriorly, edged distally by a violet-whitish line ; cell-dot 



small, black ; a rather large black dot at apex. Hindwing with termen only 



very feebly (in ? scarcely) bent at R 3 ; M 1 just separate ; the olive-grey clouding 

 covering most of the wing, leaving an ill-defined green distal area of about 4 mm. 

 width at abdominal margin but narrowing and becoming lost in the suffusion before 

 apex ; discal dot present ; postmedian line as on forewing, but scarcely beyond 

 middle of wing. 



Underside with the suffusions darker purple-grey, at hindmargin of forewing 

 and in places on hindwing irregularly relieved with whitish ; forewing otherwise 

 green, with minute discal dot ; hindwing whitish. 



La Oroya, Rio Inambari. S.E. Peru, 3100 ft., March 1905, wet season (G. R. 

 Ockenden), type c? in coll. Triug Mus.; September 1904, dry season, 1 <$, 2 ? ?. 

 Santo Domingo, Carabaya, 6000 ft., November 1901, wet season. 



Distinguished from trimaculata Warr. by the much less angulated hindwing, 

 the regularly curved postmedian line of forewing, larger apical dot, etc. 



42. Phrudocentra albicoronata sp. nov. 



<?. Closely like opaca Butl.(= abscondita Warr., nov. syn.), from the Amazons 

 and Peru, differing as follows. Vertex broadly white (in opaca green, with only a 

 very slight white admixture, or at most a narrow white band). Hiudtibia with 

 a small hair-pencil which is wanting in opaca. 



Forewing above on an average with less dark clouding. Hindwing more 



angulated at R 3 , almost as in condensata Warr. ; beneath with the purple-fuscous 

 postmedian spots extended into an almost uninterrupted sinuous band from costa 

 near apex to M 2 or submedian fold. 



Venezuela : San Esteban, June — July 1909 (S. M. Klages), type and seven 

 others in coll. Tring Mus. ; Cucuta, a worn <$ in the same collection. 



A local race(?), from Sixola River, Costa Rica, determined by Schaus as opaca, 

 has the postmedian band beneath broader and denser. I have before me only one 

 of each sex, the ? antenna bipectinate almost as in opaca, but with the branches 

 slightly shorter. • 



43. Phrudocentra eccentrica sp. nov. 



?,40 mm. Palpus slightly over twice as long as diameter of eye ; mostly 

 pale, the second joint, and the third except at its tip, with miuute scattered fuscous 

 strigulae. Antennal pectinations unusually long (five or six times diameter of 

 shaft), appreciably thickened towards their tips. Wing-shape, coloration and 

 general aspect of trimaculata Warr. 



Forewing with apical black dash stronger than in trim'icidata ; first line 

 obsolescent, an ill-defined grey cloud placed behind M just proximal to the origin 

 of M 2 ; postmedian line whiter and considerably more slender than in trimacvlata, 



slightly more oblique. 'Hindwing (as in trimaculata intermedia) without dark 



subapical spots ; a cloudy grey antemedian band, at the distal edge of which 

 stands the minute cell-dot ; postmedian line as on forewing. 



Forewing beneath with the dark postmedian band as in many examples of 

 trimaculata (broadening strongly behind, reaching tornus), the posterior dark shade 

 almost confined to a patch behind M just proximal to the origin of M 2 , thus well
