202 Some apparently new Species and Forms of Noctuidae 



ACKONYCTINAE. 



10. Magusa oenistis Hmpsn. pallida subsp. nov. 

 $ , 40—42 mm. ; ? , 35 — 38 mm. 



Differs from oenistis oenistis in the distinctly smaller size (especially 

 of the 2 ), the paler basal area of the hind wing above and the paler, 

 more ochreous areas (especially on hind wing) on the under surface — 

 typical oenistis being almost uniform red-brown beneath excepting the 

 abdominal area of hind wing. Both sexes of oenistis pallida have a 

 larger, more strongly developed, pointed black claviform, a conspicuous 

 broad pale streak (interrupted at middle by a slight red-brown line), 

 between reniform and postmedial line, a broad black mark on R 3 

 between postmedial and subterminal lines, and a horizontal black streak 

 on termen at R 2 (more conspicuous in the 2 , which has also a slight 

 dash on R 3 ). In the ? the ground colour of oenistis pallida, with the 

 exception of the base, apex, and the pale streak between reniform and 

 postmedial line, is uniform purplish-red — the pale medial shades of 

 typical oenistis being entirely wanting ; the reniform has some white 

 shading on its distal edge which is wanting in the type-form. Three 

 of the $ $ have a white spot behind M, proximally to the antemedial 

 line. 



? — ab. albiplaga ab. nov. has the posterior third of wing to post- 

 medial line irregularly suffused with white. 



Manusela, 6,000 feet, October to December, 1919 ; six $ $ , 

 three ? 2 . 



11. Trachea viridata sp. nov. 



? , 35 mm. 



Nearly allied to T. dinawa Beth.-Bak. (Cat. Lep. Phal. No. 2,896) ; 

 possibly (though scarcely probable) merely a subspecies. 



Palpus more porrect (especially segment 3) than in dinawa ; thorax 

 and second segment of palpus (in front) with some yellow shades, not 

 present in dinawa ; abdomen with the ochreous dorsal tufts absent 

 (possibly worn off). 



Fore wing only partially (not "mostly"), suffused with chocolate- 

 brown ; claviform white, without any dark definition, lunular, very 

 short and broad ; orbicular and reniform pale-green, without dark 

 points on them, extending to well behind M (especially the orbicular), 

 where they almost unite, with only a fine black line dividing them ;
