larva: Described by Masked (1890: 174, 
fig. 18). Specimen not located. 
pupal case: (Fig. 1). Length 1.0 mm., 
width 0.7 mm. Derm pale but with light 
brown pigmentation in the median cephalic 
area and in the median and subdorsal area of 
abdominal segments 2-6 inclusive. Elliptical, 
widest behind mid-length, raised on vertical 
white wax palisade. Margin crenulated, about 
20 crenulations in 0.1 mm. Thoracic tracheal 
fold present. Tracheal pore (Fig. 2a) semi-

posite the pore narrower than the others. 
Abdominal tracheal fold and pore absent, 
crenulations not noticeably narrower. Sub- 
marginal area with a single row of about 55 
fairly sharply conical papillae of uniform size 
on each side. Abdominal segment 7 not as 
narrow as in vaporariorum. Subdorsal papillae 
absent. One pair of para-median cephalic 
setae, one pair on each of first and 8th ab-
