NOTITATES ZOOLOUICAE XXIII. 1916. 41 



Nov. Zool. ix. 369 (which is perhaps also a Eurychoria, though I believe 

 " Peratostega" pattidicosta Warr., Nov. Zool. x. 269, to be its <?) but differing in 

 the more ochreons underside ; otherwise variable. One ? is identical with the 

 Aroa River type, the other nearly unicolorous, with broad but weak grey transverse 

 shades ; the 3 is almost as unicolorous above as vulpina. 



87. Trochistis felix sp. no v. 



<$, 33 mm. Extremely similar to the ? of rujoliva Warr. (Nov. Zool. xiii- 

 153), differing from that species in having the crown, antenna and upper extremity 

 of face pale, abdomen without blackish admixture on posterior segments above 



(overlooked in Warren's description), anal tuft stronger. Forewing with apex 



perhaps slightly blunter ; the olive-grey parts slightly more yellowish, more ex- 

 tended than even in ? rufoliva, uninterrupted along costa, broader in median area 

 and forming larger and more numerous spots in distal area ; white discal spot 



smaller, red-ringed ; the red lines rather more strongly bent. Hindwing with 



similar increase in the pale olivaceous colouring ; red lines better expressed, more 

 bent; scattered bluish white scales, which appear in places on the red areas of 



rufoliva, are entirely wanting. Underside slightly more reddish than in rufoliva, 



the submarginal grey shade on hindwing weaker. 



Near Oetakwa River, Snow Mountains, Dutch New Guinea, up to 3500 ft., 

 October— December 1910 (A. S. Meek). Type in coll. Tring Mus. 



88. Polycrasta ocellata Warr. 



(J Polycrasta ocellataWa.Tr.. Nov. Zool. iii. 302 (1896). 

 ? Petelia uiconspicua Warr., Nov. Zool. iii. 400 (1896). 



This synonymy, in spite of strong sexual dimorphism, is indisputable ; the 

 forms regularly occur together and agree in all essentials. Polycrasta ocellata 

 Warr., Nov. Zool. ix. 369, also 8, is presumably an aberration, at most a local race 

 (Solomons). The species is distributed in New Guinea and its satellite islands and 

 reaches North Australia. 



89. Eugnesia sciagraphica sp. nov. 



3, 29-32 mm.; $, 36 mm. Extremely like decolorata Warr., Nov. Zool. x. 

 383), but larger, slightly more yellowish, the greyish shades still weaker, first 

 line of forewing and second of hindwing rather straighter, and differing markedly 

 in the palpus. In decolorata the face has a dark red spot on each side, placed 

 about the middle, the first joint of the palpus has a blackish spot on middle of outer 

 side, the second joint is externally blackish except at base, the third joint almost 

 wholly blackish. In sciagraphica the spots on face are more mixed with black 

 (usually smaller), the first joint of palpus nearly as in decolorata, the outside of 

 second joint only blackish in its middle, the third joint entirely light, except a few 

 scales at base of npperside. 



Mount Goliath, Central Dutch New Guinea, about 139° E. longitude, 5000- 

 7000 ft., January— February 1911 (A. S. Meek). 7 $$, 1 ? in coll. Tring Mus. 



In addition to the differences noted above, the dark spots in outer area (behind 

 R 3 near second line and on R 1 near termen) are more concise (and generally smaller) 

 on forewing, obsolete on hindwing.
