Face and forelegs of 6 briglit red ; thorax and abdomen sometimes dark 

 fnscons ; the shonklers always pale grey. 



The discal spot of forewing is ineonspicnons, especially in the tJc?. 



These New Guinea specimens expand 30 mm. in the ? , and 22 mm. to 24 mm. 

 in the S S.

9. Celerena hirtipes spec. nov. 



Forewing : pale yellow ; the costa black to middle ; the outer three-fifths of 

 wing black, containing a large oblong yellow blotch from costa beyond middle 

 towards anal angle, its sides generally parallel, but sometimes swollen below ; 

 the inner edge of the dark portion diffuse ; the yellow triangular basal area nearly 

 always more or less suffused with slaty grey, in the extreme cases with only the 

 base of cell j'ellow. 



Hindwing : yellow, with a broad black border from before apex to above anal 

 angle. 



Underside like upper ; the basal area unsuffused, but always more restricted 

 than above, the transverse black bar being broader. 



Face, palpi, thorax and abdomen yellow ; the tips of palpi blackish. Fore- and 

 midlegs and hindtarsus dark ; hindtibia with a large tuft of dark hairs at extremity. 



Expanse of wings : 08 mm.

The furrow in forewing of i lies in the cell, as in culgaris Butler and proxima 

 Meyr. In one ? example the slaty grey suffusion embraces not only the basal area 

 of forewing but the marginal areas of both wings, as in C. griseofusa Warr., but in 

 that species the shape of the yellow blotch is quite different. Both species have a 

 dark tuft of hair at the end of the hindtibia. 



10. Celerena nigriceps spec. nov. 



Forewing : deep yellow, the costa broadly black to middle, before which 

 an oblique black bar runs to anal angle and joins the marginal black area ; the 

 yellow postmedian blotch bluntly pointed towards anal angle. 



Hindiving : deep yellow, with a nearly uniformly broad black border from 

 before apex to anal angle. 



Underside the same, but the transverse black bar broader. 



Face, palpi, vertex, and shoulders all black ; patagia, thorax, and abdomen 

 yellow. Fore- and midlegs and last four segments of hindtarsus dark ; hindtibia 

 and first segment of tarsus yellow ; both slightly swollen, but without excrescences 

 or tufts of hair. 



Expanse of wings : c? 44 mm ; ? 44 — 48 mm. 



6 cJcJ 3 ? ?. 



In this species the furrow in forewing of 6 is short, and runs below the cell, 

 not through it ; both wings are shorter and broader by comparison, the hindwing 

 especially ; antennae of the d simply ciliated.
