molt took place on a warm-morning and required less than 3 minutes 
for its completion. The male has been seen to assist in the molting 
of the female deutonymph. The attending male, following the 
transverse splitting of the skin, inserted his palpi, on one occasion, 
under the old skin, and forcibly pulled it over the end of the female’s 
abdomen. 
THE ADULT. 
DESCRIPTION OF FEMALE (PI. II, fig. 5). 
Color variable; at times rusty green, sometimes greenish amber, or 
yellowish, at times almost black, but more often brick red or ferrugi- 
nous red. Pigmented blotches occur almost invariably on the sides 
of the body, which are usually coalesced to form two large dark spots, 
one on each side extending from the back of the cephalothorax to the 
posterior region of the abdomen. These are often interrupted pos- 
teriorly to form a large anterior and a small posterior spot. These 
spots arise from underlying paired organs. Almost directly over 
coxe II are the carmine eyespots located on each side, near the 
margin of the cephalothorax. Legs pale amber, much paler than 
ground color of body. Palpi pale salmon. Dorsal bristles pale, not 
arising from tubercles. Body pyriform oval, widest across posterior 
region of cephalothorax; bristles in four rows, each succeeding pair 
becoming shorter; the frontal pair a little over half as long as the 
subfrontal pair, which, hike the median pair next behind, are two- 
fifths the greatest width of body. Mandibular plate about twice as 
jong as broad, tapering slightly forward, broadly rounded at tip, with 
a slight median notch. ‘‘Thumb”’ of palpus in shape somewhat 
like a truncated cone, the dorsal face about one-third longer than 
greatest width at base, the upper surface twice slightly depressed 
transversely, with an intervening dilation, bearing on its tip a 
subcylindrical ‘‘finger’’ which is about two-fifths as wide at its base 
as the distal end of the ‘‘thumb.”’ On its upper side, just above the 
‘finger,’ are two stout, straight hairs arising close together, one 
medially and the other laterally, which do not greatly exceed in 
length the ‘‘finger.’”’ Near the middle of the upper side is a smaller 
‘‘finger’’ three-fourths the length and one-half the width of the ter- 
minal ‘‘finger’’ and very similar to the latter. Between this dorsal 
‘‘finger’’ and the base of the “thumb”’ are 2 strong, curved hairs about 
equaling those at tip of ‘‘thumb,” and at middle of latero-ventral 
aspect of ‘‘thumb’’ arises a hair about equaling the latter. The 
penultimate palpal joint bears the usual claw, which reaches about 
to the basal ‘‘finger,” and also bears 2 bristles, one arising dorsally at 
base of claw which hardly equals the length of claw, and one aris- 
ing near center of outer side which about equals the dorsal bristle. 
Legs I hardly equal the length of body from the anterior margin of
