and strong postmedian line, incurved at K 2 , lobed outward at R 3 ;

18. Nothabraxes barlowi sp. nov. 



? , 61 mm. 



Head mostly black, the palpus beneath (and perhaps the face, which 

 is somewhat damaged) with some ochreous hair. Thorax mottled, 

 black and creamy white. Abdomen robust, orange with black spots and 

 broken belts, much as in commaculata Warr. ; ovipositor long. Legs 

 predominently black, the hind tibia in its proximal part pale ochreous 

 and with the spurs partly of the same colour. 



Fore wing black, with three large cream-white patches, which 

 contain some irregularly (and somewhat asymmetrically) placed black 

 spots or large dots ; a basal patch about as in commaculata Warr. (about 

 9 mm. long in middle, irregularly rounded distally) ; a costal patch about 

 6 mm. long anteriorly, irregularly narrowing and ending in a black point 

 at M, containing the elongate cellmark, its other black spots mainly 

 costal ; a narrow patch midway between end of cell and termen, com- 

 mencing at R 3 and ending just behind fold. Hind wing light orange- 

 ochreous, its proximal hair darker ; small irregular and asymmetrical 

 black spots beyond middle, chiefly at costa and on tornal one-fifth of 

 wing ; a narrow black border, commencing at apex and tapering to a 

 point behind R 3 , but with a slight proximal projection at the radial 

 fold ; one or two small spots of the ground-colour in this border ; fringe 

 anteriorly black, then chequered (at tornus predominantly ochreous). 

 Underside similar, but with the patches on the fore wing more ochreous.
