surfaces, which evidently originated in the honey-dew also abundantly 

 covering the surface where it had evidently collected from the drop- 

 pings from the insects on the under sides of higher leaves.

The species seems closely related to I. ccgyptiacum, and i^ossesses to 

 a certain degree the same peculiarities in the arrangement of the secre- 

 tion. From the insuflficient material at hand we have drawn up the 

 following partially complete description : 



Icerya montserratensis n. sp. 



-Egg (Fig. 14, &). — Length 0.74™™. Narrow oval in shape ; red iu color; without 

 visible markings. 



Mewly hatched larva (Fig. 14, a). — Compared with corresponding stage of 

 /. rosce : The antennal club is longer lu proportion to the other joints, equaling 

 joints 3, 4, and 5 together in length; the hairs upon joint 5 are longer than in I. 

 rosce: those upon joint 6 are identical. The six anal bristles are extremely long and 

 stout, while those on the sides of the abdomen are of less than half their diameter at 

 base and less than half their length and their tubercles lack the forward bend of 

 those of /. rosce. They are, however, much longer and stouter than in I. purchasi. 

 The tubercles of the head bristles are very pronounced and the bristles reach beyond 

 the third antennal joint. The secretory pores are abundant and are not arranged in 

 rows, but occur all over the dorsum. In other respects as in I. rosw. 



Femalk larva — Second Stage (Fig. 15, c, d). — Resembles closely the second stage of 

 /. rosce. The concavity on the outer side of the club of the antenna is more pro- 

 nounced, giving the tip of the club a finger-like appearance; the hairs are shorter 

 and sparser and the longest of the six anal bristles is only one-fifth the length of the 

 body instead of one-third, as with /. rosce.
