end of fold. Cilia whitish with a submedian black band, followed by 

 a pink line and two tawny lines, respectively; cilia in torniis pinkish. 



Hind wing as in male. 



Female genitalia: Eighth segment moderately sclerotized, anapo- 

 physes short; postapophyses twice as long. Seventh sternite, a 

 moderate band, lower edge broadly concave. Bursa copulatrix very 

 large, ductus bursae Nvide, with an additional sack towards base, with 

 a strong irregular cestum which is dilated and plicate along its lower 

 third, the fold forming three free lobes, triangular and pointed, at the 

 distal end. Corpus bursae ovoid, signum of lamina dentata type, 

 transverse. 



Material examined: Luzon, Mt. Makiling (Baker), 1 cf , holotype, 

 genit. slide 5184; 1 9, allotype, genit. slide 5185 (USNM). 



An elegant species, closely related to Atasthalistis viridella (Snellen) 

 (fig. 225) but differing by a larger costal spot not continued posteriorly, 

 by color of the cilia in the female and by the genitalia. The male 

 specimen may have been bleached by light. The female genitalia 

 have been compared with those of A. viridella (Snellen) 9, holotype, 

 from Java in the Leiden Museum (slide 5512). In this species the 

 cestum-like sclerotizations of the bursa copulatrix are complicated. 

 Their central part, the cestum proper, is less sclerotized and distinctly 

 shorter than in A. diacrita. The end lobes of the folds, only two of 

 which are discernible, are much larger and semicircular. The scleroti- 

 zations of the wall of the ductus bursae, more or less encircling the 

 cestum, are lacking in A. diacrita. The hindwings are exactly similar. 



The occurrence of A. viridella in the Philippine Islands has not been 

 proven.
