218 Some apparently new Species and Forms of Noctuidae 



the abdominal white area of hind wing broader and purer white than in 

 the typical form. 



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

 3,000 feet, January to February, 1920, one $ . 



On the hind wing this subspecies more nearly resembles fiava Beth.- 

 Bak. (from New Guinea) than typical varipes, Wlkr. ; possibly the three 

 are all races of one species. 



30. Garea costiplaga Swinh. defuscata subsp. nov. 



$ ? , 34 — 38 mm. 



Head and thorax predominantly olive-brown ; pectus and legs pale 

 rufous mixed with some white and ochreous scales ; abdomen above 

 pale reddish-grey, beneath fiery-red (rather deeper in tone than in 

 typical costiplaga). 



Fore wing coloured as in typical costiplaga ; subbasal striga usually 

 obsolete ; antemedial line and costal patch about as in costiplaga 

 costiplaga, but the former sometimes with olive-brown distal shading 

 extended all across wing ; a slight black spot in cell in addition to the 

 discoidal point ; a dark oblique postmedial line almost parallel with the 

 antemedial line ; postmedial costal patch, subterminal shade and fringe 

 nearly as in typical costiplaga. 



Hind wing purplish-red, the proximal third slightly paler but not 

 suffused with brown (as in the typical form). 



Underside of both wings with rather more purplish-red suffusion 

 than in typical costiplaga ; fore wing with well-defined patch of white 

 irroration on distal third of costa (not extending to apex) ; posterior 

 third of hind wing nearly as above. 



Manusela, 6,000 feet, October to December, 1919, seven $ 3 , two 



? 2 . 



C. commixta Warr. is probably the New Guinea race of this species, 

 having the fore wing very nearly as in the darker forms of costiplaga 

 defuscata (though a little less distinctly marked), the hind wing almost 

 as in typical costiplaga. Tarika Swinh. (from Gilolo) also belongs to 

 this group of forms, but is at once distinguishable by the yellow hind 

 wing, the yellower tone of underside, the indistinct and more ochreous 

 markings of fore wing above and the more curved antemedial line. It 

 is probable that when this difficult genus comes to be worked out by the 

 genitalia several species will have to sink and a good many more will 

 assume subspecific rank.
