such, but without any description ; and, as far as I know, it has never been described 

 or figured under that name. The solitary specimen is much too worn to warrant any 

 description being made from it. It seems to come nearest to Butler's ochracea, and 

 hence I place it provisionally under Pero. Oberthiir's acitaria evidently is the same 

 insect, and, his name being accompanied both by description and figure, must take 

 tlie priority over cerinta Wlk.

Fm-ewinrjs: didl mouse-colour, thickly dusted with darker, the dark atoms 

 hecoming confluent towards the costa ; costa itself broadly straw-colour for three- 

 fourths ; at three-fourths of costa, beneath the streak, begins an acutely angled 

 brown line, edged externally with white, as iivr as the third median, and evenly 

 curved from the subcostal angle to the inner margin at three-fourths ; an oblique 

 subapical streak, and the subcostal veins before it narrowly white ; fringe reddish 

 brown tipped with white.

Polla pallidiplaga sp. nov. 



Forewings : dark fawn-colour, with a dark brown slightly wavy line from inner 

 margin near base to costa just before apex; the narrow space between it and costa 

 paler, becoming chalk-white towards the costal end, where also the brown line itself 

 changes to white ; discal dot small, black ; above it on the costa is a short oblique 

 dark brown streak; an indistinct subterminal line consisting of dark vein-spots 

 edged with whitish.

 base ; a central line of whitish linear vein-dots, and a less distinct submarginal one ;

 continued across its base ; thorax concolorous with the paler costal space of 

 forewings ; collar, face, palpi, and antennae dark ferruginous. I'nderside of fore- 

 wings ochreous fawn with an oblique white line from two-thirds of costa, below which 

 it is angulated, to middle of inner margin, followed by a dark sluule near that 

 margin; a zigzag white subterminal line ; veins beyond the middle line also white; 

 hindwings with basal two-thirds (except the extreme base) white, and a zigzag white 

 subterminal line as in forewings; discal si)ots black, distinct, in both wings.
