250 THE LEPIDOPTERA OF CEYLON. 



abdomen extending a little beyond the hiudwings ; palpi slender, squamous, obliquely 

 ascending, as long as the breadth of the head, rising a little higher than the vertex ; 

 third joint lanceolate, nearly as long as the second ; antennjB rather short and slender ; 

 legs smooth, short, spurs moderately long and stout. 



" Note. — This genus has a resemblance to Gadirtha, and to some other groups 

 of Hypogrammidge." 



OROSA TORTRICOIDES. 



Orosa tortricoides, Walker, Catal. Lep. Het. B. M. xxxiv. p. 1223 (1865). 



" Female. Cinereous ; paler beneath : forewings with two black basal diffuse 

 lines which extend across half the breadth from the costa ; an antemedial line com- 

 posed of three small black marks ; of these the second is much shorter than the 

 first and much narrower than the third, which is near the interior border ; an exterior 

 line of black jioints, which is much curved outward, and approaches the preceding 

 line at each end, and is accompanied by a small black patch near the interior border ; 

 an indistinct zigzag blackish submarginal line. 



" Expanse 9^ lines." 



Genus PAS IRA. 

 Pasira, Moore, Desc. Lep. Coll. Atkinson, p. 197 (1882). 



Forewing more acuminate at the apex than in Rivula {B. sericeaUs), exterior 

 margin more erect : hindwing shorter, and the male having a groove, which is set 

 with short hairy scales on both sides of the wing between the median and internal 

 veins, and extends from the outer margin to below end of the cell, from whence it is 

 lient below the median vein. Body slightly stouter than in Rivula ; projecting front 

 of the head, palpi, and legs similar. Venation also similar. 



PASIRA BIATOMEA. 



Pasira hintomea, Moore, P. Z. S. 1883, p. 29. 



Male and female. Pale ochreous : forewing with two minute black discocellular 

 superposed spots, another spot above the submedian vein, and a marginal row of still 

 smaller dots, the apical dot most prominent : hindwing with indistinct brownish- 

 ochreous outer border. Underside brighter coloured : hindwing brown-speckled 

 along the costal border and apex ; with a blackish discocellular streak and a marginal 

 row of small dentate spots. 



Expanse 1 inch. 



PASIRA RENALIS. 



Male and female. Pale brownish-ochreous : forewing with a prominent black- 

 speckled reniform spot ; an ill-defiued transverse antemedial and a recurved post- 

 medial series of minute black points, and a marginal row of black points : hindwino-
