Hinfhvings : the same. 



Underside duller, withont any marking ; the marginal third deejior ; the costa 

 of forewings marked with yellow. Thorax and abdomen like wings ; face and 

 vertex chocolate-hrown ; tillet and hasc of antennae whitish : palpi, pectns, and fore- 

 coxae bright orange. 



Expanse of wings : 6 37 mm. : ? :57 — 39 mm. 



One 6, three ? ?, from Tngela, Solomon Islands (Woodford). 



143. Hyperythra simplex sp. nov. 



Forewings : dnll greyish olive, with a few fnscons strignlae, and tinged with 

 reddisl) except along costa ; the lines dull reddish except on costa, where they are 

 olive-brown ; first at oue-fonrth, indistinct, narrow, curved ; second in middle, 

 diffuse and thick, but narrowing towards inner margin ; third at three-fourths, 

 curved, followed by a dull reddish grey shade, diffused to hindmargin except at 

 apex ; fringe dnll reddish. 



Ilimhcings : mostly rufous, yellower along inner margin, withont first line. 



Underside deep yellow, dotted and striated with' fulvous red ; central line 

 fulvous, blotched ; cell-spots pnrjtlish, edged with fulvous ; marginal area of fore- 

 wings wholly fulvous, except a pale triangular and subapical patch ; of hindwings 

 mixed with yellow. Palpi yellowish, apical joint wliite al)0ve ; face reddish grey 

 and yellow, tlie sides white ; head, thorax, and aljdomeii dull yellowish. 



Expanse of wings : 35 jum. 



One cf from Sula Besi, October 189T (Doherty). 



Superficially like //. lutea Cram., and like tliat species, with the cell of hindwiug 

 only one-fifth of wing, but entirely withont its distinguishing secondary sexual 

 characteristics ; hindmargin of both wings curved, not crenulated. But for the 

 length of cell, it would be a Petrodava. 



Idiotephra gen. nov. 



Forewings : elongate, narrow ; costa faintly sinuous, being slightly convex near 

 base and towards apex ; apex blunt ; hindmargin strongly oblique, scarcely curved. 



llinciwings : twice as broad as forewings, the costa strongly gibbous ; hind- 

 margin bluntly prominent in middle, and somewhat lobed at anal angle. 



Antennae of cJ long, bipectinate, the apical third filiform ; palpi porrect, 

 ronghly haired, the joints indistinct; tongue and frenulum both well-develojied ; 

 hindtibiae much thickened, with four spurs, the inner middle one longer than the 

 other three, which are quite short; jiatagia lengthened ; pectus densely haired. 



Neuration : forewings, cell nearly half as long as wing ; discocellular vertical ; 

 first median at three-fifths, second close before end of cell ; radials normal ; ~, S, 9 

 stalked from close before end of cell ; 10 free, anastomosing at a jioiut with 11, 

 which rises out of 12. Hindwings with the costal vein running nearly straight ; 

 subcostal curved upwards, the first subcostal branch rising at one-half, and slightly 

 curved at first away, but approximating to the second at an equal distance beyond 

 the discocellular, then widely diverging ; first median at one-half, second and third 

 from end of cell, and widely diverging ; a strong straight fold from base close 

 above the median, almost touching third median, and curved to hindmargin just 

 below the second subcostal ; the submedian fold straight, and similarly strongly 

 developed.
