sub-equal and each somewluit sliorter 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 

 tibiiii and the claws are unidentate at apex. The digitules are appa- 

 rently capitate ; 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™'" long and about half as wide; they are light yel- 

 low in color. It may be stated here tbat there is something radically 

 wrong about all of Miss Smith'.s measurements, the cause of which can 

 not be satisfactorily guessed at. The egg, for instance, she says is from 

 5 to 6""" long and from 3 to 4""" 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 antenna? 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 antenniB 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 larvic 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 larvai, 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 upon a single leaf. In the specimens sent us 

 by Mr. Jack, 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 

 increasing. 73 roportionately, 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 larA.e 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.
