EARLY STAGES. " Eggs and larvae dull red." (Green). 



SCALE OF FEMALE. Plate i, Fig. 3. Length, 2 mm. Usually 

 quite narrow though occasionally as broad as in aspidistrae \ brown. 

 Exuviae .9 mm. long, of the same color as the secreted portion. 



FEMALE. Elongated, rather narrow ; segmentation indistinct 

 except toward the posterior end where it is extended into broad 

 prominences. Plate 6, Fig. 4. Median and second pairs of lobes 

 present. Plate 9, Fig. 3. Median pair rather small, as in aspidistrae, 

 distinctly crenate, brown. Lobes of the second pair divided into 

 two spatulate lobules, the inner one being longer than the outer. 

 The gland-spines nearest the median lobes are small and obscure 

 while those on the anterior part of the pygidium are large and con- 

 spicuous, those between being intermediate in size. They are 

 arranged as follows: i, i, i, 1-2, 2. The marginal gland-orifice 

 between the median and second lobe on each side is situated on a 

 conspicuous prominence. The dorsal gland-orifices are few in num- 

 ber. Second row wholly absent ; third and fourth rows represented 

 only by their posterior groups, numbering i 2 orifices each, 

 Median group of circnmgenital gland-orifices, 6 7 ; anterior laterals. 

 13 15 ; posterior laterals, 10 13.
