486 PROCEEDINGS OF THE NATIONAL MUSEUM. vou xxvii. 



Pupa-case yellowish, oval to elliptical; about 0.76 by 0.48 mm. 

 The submarginal wax tubes rather short and blunt. The 

 very long rods from dorsum occurring; a jiair very close to 

 cephalic margin, a ]iair on cephalic region, a pair on tho- 

 racic region; two pairs on abdominal region; a pair at caudal 

 end; and a pair just within margin, from caudo-lateral 

 region. In adults rostrum reaching nearly to abdomen. 



Wings immaculate vaporariorum (39) . 



Dorsal secretion a thin, white wax pellicle, to which is attached a 

 submarginal series of long, glassy, curved, waxen rods from dis- 

 tinct papillae, and a more mesal secretion of shorter, similar rods 

 from large circular jiores. 

 Pupa-case yellow, elliptical, 0.85 by 0.6 mm., raised on vertical 

 fringe of white wax. Vasiform orifice with rounded inden- 

 ture and finger-like jirocess caudad ; lingula with three lateral 

 lobes and a distal lobe. In adults, wings immaculate. 



glacialis (40). 

 With a rather copious, white, dorsal secretion. 



Pupa-case yellowish, elliptical, 0.86 by 0.53 nnn., with a sh(irt, 

 downward curving, pearly white submarginal secretion of 

 wax, hiding margin of case, and three prominent, more cen- 

 tral, inward-curving columns set in a triangle. Oiierculum 

 consideral)ly broader than long; lingula spatulate, with two 



pairs of setae near distal end perseie (57). 



pergandei. See above. 



Pupa-case yellow, elliptical, 1.25 by 1 mm., raised on a very 



short, vertical fringe of white wax, with a submarginal 



series of broad, downward curving, pearly white, waxen 



ribbons, and a more mesal secretion forming a plate over the 



dorsum; the secretion, as a whole, covering case. keUoggi (14) . 



Dorsal secretion a variable submarginal series of glassy, curved rods 



from distinct pores or papilhe. 



Pupa-case yellowish, elliptical, 0.65 by 0.36 mm., raised on 



vertical fringe of white wax. Vasiform orifice with rounded 



indenture caudad; lingula four-fifths length of orifice, with 



three pairs of lateral lobes and a distal lobe. In adults, wings 



immaculate variabilis (58). 



rolfsii. See above. 

 Dorsal secretion a thin, white wax pellicle, to which is attached a 

 single, submarginal series of broad, short, glassy, waxen rods 

 closely appressed to margin ; or longer, more slender and tapering, 

 waxen rods with a variable number of very long rods among 

 them; each from a distinct papillae. 

 Pupa-case yellow, elliptical, 0.96 by 6 mm., raised on vertical fringe 

 of white wax. Vasiform orifice with rounded indenture and 

 finger-like process caudad; lingula with three lateral lobes and 



a distal lobe. In adults, wings immaculate tentaculatus (5). 



Without dorsal secretion. 



Pupa-case yellow, broadly elliptical, convex, 1.15 by 0.83 mm. A 

 short, more or less slanting, fringe all around of white wax, 

 doubtless homologous with vertical fringe. Vasiform orifice 

 broadly ovate, lingula spatulate. Dorsum void of pores and 

 papillae. In adults, wings with a distal dusky spot. 



spirwoiden (59).
