Pupa-case: — Size 0.92 mm. by 0.53 mm.; shape elliptical; 

 color transparent white with developing adult within light yellow. 

 There is a vertical ventral fringe of closely coalesced, white, wax 

 rods e.xtending to the leaf. This fringe may be seen adhering to 

 the leaf in the form of a ring when the ca.se is removed. Secre- 

 tions of the dorsum are lacking. The segments of the dorsum are 

 distinct. The abdomen bears two parallel rows of irregular 

 depressions which are indistinct in some cases. Vasiform orifice 

 subsemielliptical with the cephalic margin .straight. Operculum 

 subrectangular, curved laterally, the distal end truncate extending 

 one-half the length of the orifice. Lingula cylindrical extending 

 about seven-eighths of the length of the orifice, densely setose at its 

 distal end which bears a pair of small lobes and a pair of long, 

 straight setae projecting caudad. There are other setae on the
