 was taken on Lithraea caust i ca Hook and Arn., at Santiago, 

 by Manuel J. Rivera, October 25, 1905; also taken on 

 Quillája saponaria Mol. and Buvaua sp., by Professor Car- 

 los E. Porter, March 1913 and January 1915, at Santiago 

 and La Ligua. On the leaf the pupae appear black with 

 a very short, scanty lateral wax fringe raade up of irrid- 

 escent filaments. They are very numerous on the under 

 side of the leaf and when removed leave light colored 

 áreas where they have been located, giviug tlie leaf a very 

 raottled appearance.

 raargin toothed, Avax tubes moderately developed, incisions 

 shallow; thoracic and caudal tracheal folds present and in 

 most cases plainly visible and ending on the margin in a 

 distinctly differentiated comb of teeth from which arise 

 pencils of waxy secretion, differing from the more or less 

 araorphous secretion of wax surrounding the case, secret- 

 ed by the marginal wax tubes. Dorsum with the disk 

 uot separated from the submarginal área and withoutprom- 

 inent pores or papillae, Ihough usually wilh a number 

 of minute clear pores. (Tn rare exceptions there are many 

 wax pores). Vasiform orífice small, transverso, rounded, 

 or elongate, the inner margin rarely armed with teeth; 

 operculum filling from a third to all of the orifico and 

 obscuring the lingiila. 



Adults with wings unmarked, clouded, or spotted; 

 the radial sector of forewing with a single fiexure; no 

 spur of the media, but the cubitus faintly indicated. An- 

 tennae of seven segments, segraent III the longest; the 

 other distal ones subequal, with lY, however, usually the
