when viewed obliquely ; a buff-yellow band from W of forewing beyond M- of 



liiiulwing. -Forewing : a postdiscal band, anteriorly curved costad, a little paler 



than the ground colour, hardly visible. Hiiidwing : a discal baud of black spots, 



followed by a postdiscal line and a broadisb submargiual band of confluent lunules, 

 of a deeper colour than the ground, the submarginal baud well defined proximally, 

 but scarcely separate from the marginal line, the interspace being nearly as deep in 

 tint as the margin ; no pale fringe-spots on either wing. 



Undertside washed with clay from base to median band ; outer half mucli 

 paler than above, with the markings more prominent ; median band clay-colour. 

 Forewing with a discal row of black patches, which are not so prominent as 

 those of hindwing ; on both wings, between this series and distal margin a 

 whitish, slightly purplish line of halfmoons, followed by a much less broken 

 line, which is very indistinct on forewing. 



Length of forewing : 27 mm. 



Hah. Upper Aroa River. 



One S only. This species is, on the upperside, a close mimic of Mycalesis 

 barbara Grose-Smith, which is not a rare insect in the mountainous districts of 

 British New Guinea, and was procured in some numbers by Mr. A. S. Meek. The 

 specimens of barbara are slightly different, representing a southern subspecies, 

 which we name : 



23. Mycalesis barbara mea snbsp. nov. (PI. III. f 42. S)- 



S. Like M. b. barbara from German New Guinea, but the band of the 

 forewing, above, shorter, the uppermost spot being more or less obsolete. 



? . This sex of b. barbara is not known. The ? of b. mea is paler than 

 the c?, the discal band is broader and, on the forewing, longer, reaching to R-, as 

 in the S of M. b. barbara, the eye-spots are more prominent, and the submargiual 

 lines of the hindwing more distinct. The underside is practically as iu the $, 

 but the whitish discal band is broader, and the interspace between the eye-spots 

 and the distal margin wider.

GEOMETRIDAE. 

 24. Bordeta aroensis spec. nov. (PI. IIL f 37. ?). 



? . Body Ijlack, collar and anterior coxae pale buff, abdomen orange, banded 

 with black at the bases of the segments. 



Wings, upperside, black. Forewing : an elongate median spot, a sub- 



rotundate spot halfway to apex, and a tiny submarginal dot R' — M' pale bnft'. 



Hindwing: a large median area, extending from abdominal margin close to costal 

 edge, and two spots outside it, orange, the ujiper spot small, connected with the 

 second by some orange scales. 



Underside like upper, the markings rather larger, the orange area of the 

 hindwing extending to base and the two spots joined together. 



Length of forewing : 22 mm.
