212 Some apparently new Species and Forms of Noctuidae 



22. Stictoptera arcuata Beth.-Bkr. f. nigribasis f. nov. 

 3 , 42 mm. 



Tegulae with a black line at middle, chestnut-brown at tips ; 

 patagia dark chestnut-brown except at base. 



Fore wing to the medial line suffused with deep chestnut-brown, 

 leaving an antemedial patch on costa and an L-shaped mark against 

 medial line and hindmargin pale-ochreous ; a broad black subbasal 

 streak along costa, not continued across the wing ; the dark apical 

 markings more diffused than in a single ? in coll. Brit. Mus. (I have 

 unfortunately been unable to see Mr. Bethune-Baker's type) ; the 

 tornal dart slight and ending at postmediai line. 

 ? , 38 mm. 



Patagia and base of hind wing a little blacker than in the 3 ; 

 subapical dark marks not continued behind SC 5 ; reniform almost 

 obsolete (without black definition) ; tornal dart apparently absent 

 (the distal half of wings is much worn). 



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

 Also one typical ? of arcuata. 



Just possibly a new species, but appears to me to agree in all 

 essentials with arcuata, though the 3 fore wing is a good deal 

 broader than the ? . 



Note. 



One or two species in Nigramma or Gyrtona are most probably 

 new, but it has not seemed advisable to describe them at present, owing 

 to the great difficulty of determining the different species in this 

 subfamily and the lack of sufficient material for the study required 

 to arrive at any definite conclusions. 



SABKOTHBIPINAE. 



23. Characoma excurvata sp. nov. 



3 , 20 mm. 



Head, thorax, abdomen and legs coloured much as in curiosa Swinh., 

 but the abdominal tufts predominantly whitish-grey. 



Fore wing greyish-white, with the proximal third pale-brown ; 

 some postmediai brown shading. A subbasal black costal spot ; a 

 broad black costal streak near base and some black shading behind M ; 

 a broad black line from about one-fourth costa, outwardly oblique to
