woven texture. This covering is somewhat longer than the body and is 

 marked with depressions as shown in the photograph. With age this sac 

 may become quite dark, almost brown — the adult female body withered up 

 and only the eggs remaining. The body proper is dark purple, as stated above, 

 is rather broadly oval in shape, and becomes perfectly transparent after having 

 been boiled in KOH. The antennae remain light brown and are usually 

 7-articled (Fig. 146 D). Article III is the longest. Often the articles of 

 the antennae of the same individuals will be irregularly segmented, as is 

 shown in the accompanying drawing (Fig. 146 C). The antenna C is 8- 

 articlcd, while antenna D is normally 7-articled, with a faint sign of division on 

 the 7th article. Out of a great number of specimens examined, I found 

 that there were more individuals with 8 articles than with 7, although this 

 may be out of the ordinary. There are very few hairs on anv of the articles

excepting apical one. None of the adult forms, which were through egg- 

 laying had any legs at all, so I am not able to. give the data concerning them. 



The ventral derm has two alternating rows or rather large round openings 

 or glands from the spiracles to the pygidium. 



Pygidimii (Fig. 146 B), with one large spine and two short stout spines 

 on anal lobes, with several short spines on the inner margins. Anal ring 

 scalloped, bearing 8 long spines. Pores or gland openings scattered over 

 derm. 



Bggs. — Wine-colored or light purple. Deposited in the sac at the posterior 

 end in large numbers where they remain until hatched in the spring. 



Adult Male (Fig. 146 A). — Sac about half as long as that of the adult 

 female and narrow. The smallest scales in the photograph are the male 

 cases. The coloring is the same as those of the female.
