PolychrosiM aruiicana sp. nov. 



Expanse 8.5-11 mm. 



Head and palpi clay-yellow, latter tinged with brown on outside of tufts and 

 former with brown behind. Thorax clay-brown, thickly dotted with darker 

 brown, tuft leaden-black. Abdomen fuscous, anal tuft and legs clay-yellow, lat- 

 ter dusted and anulate with brown. 



Forewing: inner third pale grayish-blue, divided by a brown band from costa, 

 which reaches only to upper edge of cell. Costa within this space marked with 

 three black spots, edged on both sides with white. The central fascia is narrow- 

 est on costa at middle, its inner edge goes vertically to dorsal margin, its outer 

 edge obliquely to anal angle. The flattened oval brown patch in apical fourth 

 sends two spurs to costa, another from outer edge to termen and which follows 

 termen to angle, and coalesces with the central fascia at angle. These brown 

 areas are overlaid with black on upper half of wing, and with three horizontal 

 black lines in the flattened oval, beyond the end of cell with shining golden 

 ochreous on lower half. There are four geminate white spots on costa between 

 middle and apex, from each extends below costa pale metallic-blue streaks, the 

 inner one extends across the brown fascia to dorsum, but is separated into three 

 spots by the brown color. The apical and the one before it send oblique streaks 

 to termen. A line of the same scales borders lower half of termen. Cilia leaden 

 blue, with two tiny dashes of white on outer ends of the cilia below apex. 



Hindwing: dark smoky brown, cilia white outwardly ; underside grayish -brown. 



Underside forewing smoky brown, costal spots repeated.
