SCALE OF FEMALE. Elongated, nearly parallel-sided or plainly 

 broadened posteriorly ; more or less convex. Ventral scale developed 

 only at the anterior end. Exuviae at the anterior extremity, the first 

 one naked and lying partly on the second which is more or less cov- 

 ered by secreted matter. Secreted portion of scale white ; exuviae 

 varying from colorless to orange-yellow or brownish. 



FEMALE. Plate 2, Fig. 8. Elongated, broadened posteriorly, dis- 

 tinctly segmented. A more or less distinct group of small nearly 

 circular gland-orifices on each side of each of the abdominal seg- 

 ments (Plate 5, Fig. 8). These are much more distinct just in front 

 of the pygidium than near the anterior extremity of the body. 

 More or less distinct rows of oval gland-orifices on the dorsal surface 

 between the posterior segments (Plate 5, Fig. 8). A group of gland- 

 spines on each side of each of the abdominal segments, more distinct 

 near the pygidium than anteriorly (Plate 5, Fig. 8). 



The characters of the pygidium (Plate 5, Fig. 8) are as follows. 

 Two or three pairs of lobes present. Median lobes more or less 

 semicircular in outline, their bases either close to each other or 

 touching for more or less of their length, serrate, notched or entire.
