Female larva — Third Stage (Fig. 15, c, /). — Closely resembles the corresponding 



stage in I. rosce. The body appears slend- 

 erer and. the legs stouter in the specimens 

 at hand, but they may not exactly corre- 

 spond, in age. The last joint of the anten- 

 nse is longer, equaling 8, 7, and. half of 6 

 together in length ; the chitinous band at 

 base of front coxae is much slenderer, the 

 tarsi are less curved, the hairs along the 

 margin of the body are shorter and not so 

 dark in color, and the antennae are lighter 

 in color, while the mentum and rostrum 

 are hardly differentiated, in color. The 

 general colcr is red but duller than in I. 

 rosce. Occasionally joints 4 and 5 are con- 

 solidated, makiug the antennse appear 

 eight-jointed, with joint 4 nearly equal to 

 3 in length. In two specimens before us 

 this occurs in the antenna of the left side 

 and not in that of the right, and in another 

 specimen it occurs in both antennae. In 

 one specimen joints 4 and 5 and joints 7 

 and 8 are consolidated in the left antenna, 

 making it appear seven-jointed, while in 

 two others joints 4 and 5 appear separated 

 from below and consolidated from above. 

 The secretion is very abundant and pre- 

 sents a similar tufted appearance, the tufts -arranged in dorsal, subdorsal, and lateral 

 rows, about five to the 

 dorsal row, six to each 

 subdorsal, nine to each 

 lateral, and one each to 

 head and anus. The 

 anal tuft early begins to 

 exceed all the others in 

 length, and by this 

 character alone this 

 species can in this stage 

 be easily distinguished 

 from I. rosce. In some 

 of our specimens in this 

 stage it has reached a 

 length of 3™™ and pro- 

 jects directly back- 

 wards, doubtless sup- 

 ported by the long and 

 strong anal bristles. 

 The color of the wax is 

 light lemon yellow. 



Adult female (Figs. 

 16 and 17).— General 

 color, reddish yellow ; 

 antennae andlegs black; 

 broadly oval in shape, 

 somewhat convex, 4™™ 

 long by 2.5™"^ broad ; hairs very inconspicuous and sparse, very much less incon- 

 spicuous around the lateral margin than in 7. rosce; sutures of segments distinct; body
