6 NOVITATBS ZOOLOGICAE XXIII. 131P. 



15. Celerena mutatipes sp. nov. 



( ^ ) 57-60 mm. Head yellow, on vertex sometimes mixed with black. Palpus 

 with third joint small ; yellow, the extreme upper edge, end of second joint, and 

 third joint black. Antenna with the proximal segments not ciliated, the modified 

 sexual scales commencing quite near base. Collar yellow, somewhat marked with 

 black. Thorax and abdomen yellow. Hindtibia yellow, the terminal process 

 mixed with grey, longer than the first tarsal joint. Hindtarsus with first joint not 

 very long, the triangular process strong, reaching nearly to its end, with the outer 

 angle rounded off ; mixed with grey ; second joint fully three times as long as the 

 unthickened extremity of the first. 



Forewing rather narrow; furrow in cell strong; bright gold-yellow; costal 

 margin black from base to transverse baud; black band moderately broad, from 

 costa before middle to tornus, joining a not very narrow black distal border, which 

 widens gradually into the usual apical patch ; the enclosed yellow area about as 



broad as the distance from its distal edge to apex. Hindwing concolorous, with 



the black border of medium width, somewhat wider in anterior half than in posterior, 

 its proximal edge not very regularly rounded. 



Upper Aroa River, British New Guinea, January — March 1903 (A. S. Meek). 

 Type and others in coll. Tring Mus. Ekeikei, British Central New Guinea, 

 1500 ft., January— April 1903 (A. E. Pratt); two pairs in coll. Brit, Mus. 



Easily distinguished by the proportions and structure of the c? hindleg. 



? smaller (48-54 mm.), usually with more black on front of thorax, the band 

 across the forewing broader. Both sexes are, however, strongly variable in the 

 latter respect, producing aberrations in which this band is as wide as the yellow 

 space between it and the base. In a S in my collection, merely labelled German 

 New Guinea, it is on the contrary narrower than in any Aroa River specimen 

 known to me, and the black of the distal margin is (except in its proximal part) 

 greyer ; hindleg clearer yellow. This will probably prove a local race, superficially 

 recalling the structurally distinct species mitis Warr. 



Subfam. HEMITHEINAE. 

 16. Archaeobalbis cristata subspoliata subsp. nov. 



8 ¥ , 55-57 mm. Differs from cristata cristata Warr. ( = subopalina) as follows : 



Larger, both wings slightly broader, the termen slightly more convex, the 

 cell-spots beneath somewhat enlarged, the submarginal band beneath without red 

 admixture, on the forewing broad anteriorly, tending to obsolescence posteriorly 

 and especially in middle (R 3 — M 1 ). 



Nilgiris, type <? and ? ; Coorg (Mercara), a ? ; all in coll. Tring Mus. 



Probably replaces cristata cristata throughout Southern India. 



17. Archaeobalbis cristata nigrescentipalpis subsp. uov. 



Like sharply marked examples of cristata cristata Warr. — with the following 

 differences : 



Palpus at tip (third joint and especially end of second joint) black or blackish. 

 Foreleg rather more mixed with black. Hindwing with termen slightly more 

 regularly convex. Both wings above with the dark shades (especially the proximal)
