(?. A dnodez edition of P. buchholzi, in appearance like Praedora marshalU 

 (PI. V. f. 16). Legs as in P. biichliolzi, but first segment of hiudtarsns not longer 

 than segments 2 to ii together ; clasper with a similar patch of friction-scales. 



Antenna longer than cell of forewirtg, stont, strongly compressed, sliglitly 

 incrassate beyond middle. Occi]int and thorax olive above, mesothoracic tegnla 

 with ill-defined black lateral line which is bordered with creamy white beneath ; 

 abdomen with dorsal mesial row of black spots; fringe of tergites chequered 

 black and creamy white ; sides of proximal tergites with ill-defined blackish 

 patches ; underside of abdomen dirty white, a series of small black mesial spots, 

 standing at the bases of the segments ; breast greyish brown, paljjus brown ; 

 tarsi blackish, tips of segments and of mid- aud hindtibia white. 



Wings, upperside, similar to those of Poliana hnchlwhi and Praedora 



marshaUi. Forewing with wliite stigma, the pair of antemedian lines joined 



in middle to the pair of discal lines as in Praedora marshalU ; a postdiscal line 

 more or less interrupted at the veins, parallel to the discal pair, sliglitly bordered 

 with grey proximally ; a snbmarginal zigzag line ; fringe blackish brown aud 



white. Hindwing brown, greyish just behind cell, a very indistinct trat f 



a pale discal band : fringe white, brown at ends of veins.

 sinuate. ( !laspcr (Fig. 0) broad, dorsal and ventral margins almost parallel, a])ex 

 rounded, slightly acuminate ; harpe raised into a slender, strongly chitinised, 

 sharply jiointed process, which stands some distance away from the ventral edge 

 of the harpe, and ])rojects dorsa<l and then distad, being dilated before the en<l, 

 which is somewhat twisted ; fri<tion-scales erect, forming a consi)icuous crest, 

 above which there is an impression covered with minnte scales. 



L(uigth of forewing : tj, 21 mm. 



Ilab. Ganale U., 13. iv. 1902.

 ? . Tongue vestigial, rei)re8ented by two short lobes, covered witli long scales.
