Adult Female: At the time of spinning the ovisac, large, 3.7 mm. 
(4.1 mm. with caudal appendages) by 1.65 mm. broad, becoming 
somewhat narrower towards the anterior and posterior ends; color 
purplish, showing distinctly through the ashy white secretion; segmen- 
tation very distinct; legs and antenne very pale; lateral wax appendages 
absent, caudal ones stout at base, somewhat conical, snow white, and 
appearing granular. Inner pair longer and stouter than the outer 
ones. Until the females attain approximately the size 2.4 mm. long by 
1.1 mm. broad they remain free-moving. (Plate XIV, Fig. 4). After this 
the ovisac is commenced—a silky mass which ultimately completely 
envelopes the insect. This is spun from the posterior end forward, 
as shown in Figs. 5 and 6, until, in the end, it forms a complete 
covering for the female, and later the ova. 
Antenne: Plate XV, Fig. 6.

Sete of Anal Ring. 104u to 128 yu long. 
Unfortunately, although 35 specimens were mounted, nearly all 
the setz of the anal lobes were lacking. It commonly happens in 
clearing specimens in K O H etc., that a number of the hairs, spines, 
etc., are lost but I have never found it occur to such an extent as in 
this species. Plate XVI, Fig. 2 shows the distribution of spines and 
pores round the anal lobes. 
Type Slide: On this slide are three specimens, arranged, with the 
slide in front of one as labeled, in the form of a triangle. The insect at 
the apex is here described as ‘‘a,’’ the one at:the left as ‘“‘b,’’ and the 
one on the right as “‘c.”’ 
Specimen “‘a’’: Size, mounted, 2.8 mm. long by 1.4 mm. broad. 
Pores of derm small and scattered, sparingly supplied with small 
hairs, especially across the middle zones of segments. Hairs on dorsal 
surface more numerous and longer, sometimes attaining length of 90 wu. 
Antennal segments: One antenna folded. Segments of other, in 
order 1 to 8, measured inp are 58, 68, 48, 36, 42, 27, 36 and 89. It 
should be mentioned that Segment IV, measuring, in this specimen 
36 wis the longest found in the whole series. The usual length for joint 
IV is about 28 py.

Sete of Anal Ring: About 128 u. 
Legs: The measurements of the legs on the right side of the insect— 
left side as mounted with ventral side up are given in w. It should be 
noticed that seven measurements are given, and the illustration shows 
the scheme adopted. The Coxa and trochanter are unsatisfactory as
