446 Some apparently new Noctuidae from Sumatra, etc. 



distal brown markings and with the subbasal brown patch reduced to a 

 triangular mark at costa and an irregularly-triangular spot in base of 

 fold ; all the lines blacker than in biformis, the medial more continuous ; 

 additional very fine black lines intersecting the green areas on each side 

 of the medial line, arising from the spots usually present on the costa of 

 biformis ; some black streaks on the veins towards termen. 



Hind wing somewhat as in biformis, but rather paler at base, with 

 the postmedial line less angled towards anal angle and with an additional 

 (medial) straight, diffused, slight brown band. 



Underside of wings rather greyer in tone than in biformis, with the 

 postmedial line rather more angled behind costa of both wings' and with 

 a better developed medial shade on hind wing.

21. Belciana subserrata sp. nov. (pi. XV, fig. 7). 

 $ , 55 mm. 



Palpus yellowish-white, shaded with green and brown ; head pale- 

 green ; tegulae brownish-orange, tipped with green ; thorax dull yel- 

 lowish-green ; abdomen (discoloured) apparently yellowish, the first 

 abdominal crest large, deep reddish-brown, the other crests small and 

 black; abdomen beneath, pectus and legs ochraceous-yellow, more or less 

 shaded with brown, the fore- and mid-tibia with small patches of green. 



Fore wing dull yellowish-green, marked nearly as in B. serrata 

 Beth.-Bak. {Biptheroides serrata Beth.-Bak., Nov. Zool., xiii, 204 

 [1906] [Brit. New Guinea]), but without the heavy black subbasal 

 and subapical shading, which is almost always a strongly-marked 

 feature in serrata; medial and postmedial lines less dentate than in 

 serrata ; subterminal dart-like mark very slight ; fringe very narrowly 

 chequered with black. 



Hind wing coloured as in serrata, but the dark border ending (on 

 anterior half of wing) at postmedial line, and showing a slight pale 

 line on distal side of postmedial ; the yellow shade slightly deeper 

 in tone than in the majority of serrata specimens. 



Underside somewhat as in serrata, but proximally deeper yellow, 

 with the dark markings rather more diffused and obscure; termen of 

 fore wing rather more broadly pale-green ; dark border of hind wing 

 not interrupted by terminal pale spots.
