sub-equal and each somewhat shorter than 9. Joints 6-8 are also sub- 
equal in length, any two of them together being a little longer than 
joint 9. The tarsi are rather more than one-third the length of the 
tibiae and the claws are unidentate at apex. The digitules are appa- 
rently capitate j the ano-genital ring is punctate and bears six long hairs. 
The eggs, which are found very numerously in the waxy secretion, 
are from 0.3 to 0.4 mm long and about half as wide; they are light yel- 
low in color. It may be stated here that there is something radically 
wrong about all of Miss Smith's measurements, the cause of which can 
notbe satisfactorily guessed at. The egg, for instance, she says is from 
5 to 6 mm long and from 3 to 4 mni wide. Even on the supposition that 
she meant tenths of millimeters instead of millimeters, her meas- 
urements would still be too large. 
The female larva is pale yellow, elongate oval, tapering gently 
toward each end. The antennae are 6-jointed, joint G about as long 
as the three preceding ones combined, joint 2 somewat longer than any 
of the following three, each of which gradually shortens from 2 to 4. 
The eyes are dark purplish. The head in front of the antennae bears 
four slender hairs. There is one short spine just in front of each eye, 
three similar spines each side of the prothorax, and one on each side of 
all the remaining segments. The anal lobes bear two or three short 
hairs or spines and one long bristle. 
The male larva is reddish yellow in color. The adult male is also 
red, and is shown in detail at Fig. 24 c. 
When the eggs hatch, the young larvae remain upon the leaf, unless 
this should be too crowded, when they crawl down the petiole and 
seek food from some healthier leaf. The male larvae, on reaching full 
growth, become restless and wander about over the trunks and limbs 
of the trees for from seven to ten days (Fig. 23 &), and finally secrete them- 
selves beneath the roughened outside bark of the tree and transform 
to pupa. In about fifteen days the perfect male issues from one end of 
the waxy cocoon. By this time the females have become mature, have 
left the leaves and wander about the limbs or trunk. Here they are 
sought by the males. The growth of the female thereafter is rapid, 
and she soon settles upon the underside of the leaf. In this stage the 
females seldom crowd the leaf, and Miss Smith states that not more 
than three or four remain ujKm a single leaf. In the specimens sent us 
by Mr. J ack, however, we have counted as many as thirteen on the under 
side of a single leaf. The waxy secretion soon becomes very dense, and 
the eggs are pushed out into it, both secretion and number of eggs 
in creasing, proportionately, and the number of eggs ranging from 500 
upward. The body of the female gradually shrivels. 
Miss Smith found that there are three generations each year. Through 
the winter months the larvae are to be found in the crevices of the 
bark, on the trunk, and at the base of the larger limbs. During the 
warm days of winter they crawl out and are quite active. They make
