twice as short. (In T. argessa the genital segment, especially its 

 sternite much less sclerotized, excision shallow.) Slide 4981 studied. 

 Material examined: Luzon, Mt. Makiling (Baker), 1 9, paratype, 

 slide 5215. 5 cf 20 9 (USNM). 



Psorosticha Lower, 1901 



Psorosttcha neglecta, new species 



Figures 286-288, 661-662 



Male, 19 mm; female, 20 mm. Head and thorax fuscous grey 

 (sometimes dark grey) mixed with white (tips of scales), appearing 

 grey. Palpus creamy sprinkled with dark grey, median segment with 

 a dark grey spot at base above, another, larger spot at apex above; 

 terminal segment with a dark grey basal ring and a grey, whitish- 

 mixed median tufted ring, apical half of segment creamy. Antenna 

 rather thickened in male, grey, scape whitish. Abdomen brownish 

 fuscous, anal tuft pale ochreous. 



Forewdng oblong, broadest at 1/3, costa ciu^ved at base, less curved 

 in middle, apex rounded, termen rounded, oblique. Pale fulvous 

 pinkish strewn with blackish-grey scales and blackish-grey raised 

 tufts. A wedge-shaped basal patch, leaving a narrow edge of dorsum 

 beyond base unobsciu"ed; two small dark tufts in an oblique row, on 

 1/4 of costa and in middle of fold, respectively; a more oblique series 

 of some five points from below the first tuft to fold well beyond the 

 second tuft; two larger transverse tufts in a series from about 3/5 of 

 costa to 3/4 of dorsum, first tuft subcostal, second largest, along closing 

 vein, a group of minute raised scales on dorsum; posterior portion of 

 wing from before the larger tufts to before apex and termen and not 

 reaching tornus, denser speckled with dark scales, sometimes a cloudy 

 triangular greyish costal patch just before apex; terminal edge with a 

 series of narrow black marginal marks from below apex to tornus. 

 Cnia concolorous. 



Hindwing glossy, pale grey bronze, cilia paler, whitish grey, with a 

 bronze subbasal shade. 



Male genitalia: Rather similar to those of P. zizyphi Stainton 

 (India) but with harpe ("clasper") more robust and straight, dilated 

 at base. In P. melanocrepida Clarke (Japan) the clasper is longer and 

 sinuate. 



Female genitalia : Signum very long and slender, quite distinct from 

 that in P. zizyphi, where it is moderate, and from that in P. 

 melanocrepida, where it is short.
