Some apparently new Species and Forms of Noctuidae 237 



54. Athyrma perficiens Wlkr., olivacea subsp. nov. 

 $ ? , 46—53 mm. 



Differs from Indian specimens of perficiens Wlkr. in the more olive- 

 grey (less ochreous) tone of ground-colour, the larger antemedial black 

 patch (which extends to near base of hindmargin), the rather darker 

 costal shading before postmedial dark patch and at apex, the much 

 straighter distal edge of the postmedial black patch (which is sharply 

 denned distally by a white line), and especially in the straight, red- 

 brown postmedial shading from costa to hindmargin (which in perficiens 

 perficiens is obsolete on the radials and angled inwards on M 2 ). Under- 

 side rather darker grey than in typical perficiens. Possibly a distinct 

 species, but probably a race of perficiens, with which it agrees perfectly 

 in margins and fringes, as well as structurally in the presence of a 

 grooved band along the distal half of R 1 of the hind wing. 



Manusela, 6,000 feet, October to December, 1919, two $ S , one ? . 



Hampson in his " Moths of India " sank this species to bubo Hbn., 

 but it is at once distinguishable in the $ by the grooved band on R 1 

 of the hind wing, which is entirely absent in bubo. Both species are 

 represented in Central Ceram, occurring together but very distinct. 



55. Athyrma pratti (Beth.-Bak.) ? . 



$ , Hypaetra pratti Beth.-Bak. Nov. Zool., xiii, p. 262 (1906). 

 $ , 52 — 54 mm. 



Head, thorax, abdomen and legs much as in the $ . 



Fore wing brown ; some violet irroration, most conspicuous at base 

 and near termen. Subbasal, antemedial and postmedial costal spots 

 as in the $ ; antemedial black patch proximally as in the $ , distally 

 nearly erect instead of oblique (reducing the size at hindmargin) ; black 

 orbicular spot rather conspicuous ; medial lines almost obsolete ; post- 

 medial black patch only represented by a small black patch between R 1 

 and R 2 and a smaller spot behind M 1 , the two being connected by 

 a thick black line which is retracted to the origin of M 1 after the second 

 black spot, then oblique and waved to hindmargin at about two-thirds. 



Hind wing and underside of both wings much as in the $ . 



Manusela, 6,000 feet, October to December, 1919, five ? ? , 

 five $ $ . 



Possibly a new species, but seems to me probably the missing 2 of 

 pratti, the body, shape and general tone being the same, although the
