Pupa case broadly oval, about .70 x .42 mm., slightly constricted 

 before the middle, light greenish yellow, dorsum nearly flat, 

 slightly convex, furrowed transversely according to segmentation, 

 marginal area radially and deeply corrugated or wrinkled, margin 

 finely crenulate. Six pairs of straight or slightly curved upright 

 wax rods from 200 /x to 230 fx long are borne upon the marginal 

 area of the dorsum ; one pair each at cephalic and caudal extremi- 

 ties, the other four pairs nearly equidistant from each other and 

 slightly nearer to the cephalic than to the caudal pair. Two other 

 pairs of slightly shorter rods occur on the disk of the dorsum, one 

 pair on metathoracic segment just in front of the transverse split- 

 ting line, each rod being about half-way between the margin and 

 the center, and the other pair is similarly located on the fifth 

 abdominal segment. There is a submarginal fringe of smaller 

 (about 90 fi long) curved wax rods rising upward and then curv- 

 ing outward. Vasiform orifice, subtriangular with angles rounded 

 and sides bulging. Operculum semicircular, five-sevenths as long 

 as broad, reaching half the length of the orifice, base nearly a 

 straight line, apex broadly rounded. Lingula spatulate, irregu- 

 larly seven-lobed, three lobes on each side with the terminal lobe 

 between two setae which are about 16 ll long. Lobes minutely and 

 densely papillose. 



Adult female: Length about 1.15mm., fore wing about i.x 

 .38 mm., white, immaculate ; legs and body yellow ; eyes constricted 

 but not divided. Male somewhat smaller.
