Pupa case about .7 x .43 mm., elliptical ; dorsal disk varies from 

 dark brown or smoky black to whitish. Margins whitish ; dorsum 

 nearly flat, medio-longitudinal portion slightly ridged or keeled. 

 A submarginal row or series of short and blunt papillae give rise 

 to rather short, more or less curved, glassy, wax rods which form 

 a narrow fringe. On each side there is a subdorsal series of very 

 minute circular transparent spots, and along each side of keel a 

 row of irregular depressions ; there is a pair of well developed 

 setae just inside the caudal margin, a smaller pair at vasiform 

 orifice, and sometimes a pair of small setae on cephalic segment 

 and on first abdominal segment. Vasiform orifice subcordate, 

 ending in two rounded lobes appearing as though truncate; 

 operculum sub-elliptical, broader than long, and about half as long 

 as orifice; lingula lobed, distal four-fifths setose, armed with a 

 pair of setae, about three-fourths as long as orifice. A narrow 

 furrow extends from orifice to caudal margin. 



Adult female, about .84 mm. long, fore wing about 1.07 x 

 .49mm., yellow, frons deep brownish black; antennae and legs 

 paler ; eyes deep red, constricted at the middle ; wings marked 

 with two irregular bands of reddish brown, the proximal band 

 crossing the wing near its middle, appearing in front of the vein, 

 as an irregular rhomboid, and back of it, an irregularly V-shaped 

 spot, the apex of the V being distad ; the distal band crosses the 

 wing at its widest point. A reddish brown spot occurs at base of 

 wing just back of the veins, and a similar colored strip extends
