N0.215G. SUBFAMILY ALEYRODINAE—QUAINTANCE d BAKER. 345 



faintly appearing structure of about the same size as the tooth. 

 Within the rounded portion of the inner extremity of this structure 

 a dark area is situated, which may represent the secreting area of the 

 marginal tubes. On the submarginal area between these structures 

 and the row of spmcs, the surface presents a granular or irregularly 

 striated appearance. The vasiform orifice (fig. 3) is situated on a 

 tubercle. Its shape is that of a rounded triangle and its inner 

 margin m many specimens is irregularly waved or toothed. The 

 operculum almost entirely fills the orifice obscurmg the lingula. 

 Near the cephalic lateral margin of the orifice a pair of small spines 

 is situated one on either side. 



On the leaf the pupa case is solid black with the spines appearing 

 a dark brown. There is a very slight irregular waxy secretion on the 

 dorsum, mostly on the subdorsal area. When this is present in any 

 quantity the median ridge shines through as a jet black area. On 

 the lateral margin there is a fringe all around of dull white wax which 

 is not even but broken up into plates or sections, some of which are 

 considerably longer than others. In some cases these have a slight 

 wooUy appearance, but usually are dull and waxy in appearance. 



Adult. — Unknown . 



Described from numerous pupa cases in balsam and dry upon the 

 leaf.

This species is represented by four different lots of material. The 

 type lot was taken on mango by R. S. Woglum at Bombay, India, in 

 1909. Another lot was collected from the same plant by Mr. Woglum 

 at Saharanpur, India, m October, 1910, and a third lot was taken by 

 him at Dehra Dun, India, on the same plant m November, 1910. 

 Besides this material there is one slide containmg eggs, larvae, and 

 pupae, which was received from Mr. J. G. Sanders and marked 

 "Imported plant, India, October 8, 1908." The pupa case on this 

 shde shows a shght variation from the t3q)e in regard to the relative 

 length of the submarginal spines, but as considerable variation occurs 

 between specimens, and even sometimes between the two halves of 

 the same specimen, there seems little doubt that Sanders's material 

 is of the same species. 



Egg (figs. 2 and 3). — Length 0.24 mm., width 0.128 mm. 

 Somewhat oval in outline, and curved with the stalk situated near 

 the larger end; color fight yellowish brown; stalk short; surface 

 covered with hexagonal markings, the average diameter of which is 

 0.06 mm.
