When the plants were turned out of the pots the insects were 

 found to be well distributed but they were more abundant upon 

 those portions of the roots which came in contact with the pots. 



At the time of their discovery only apterous specimens were 

 present. These apterous forms had five-segment antennae and 

 gave all the appearances of stem mothers. We were unable to 

 ascertain, however, with any assurance that they were stem 

 mothers since no eggs were obtained and since all reared indi- 

 viduals of the next generation proved to be winged. 



We were thus able to secure only two forms, the five-segmented 

 apterous form and the alate form. The alate specimens not 

 preserved for description left the plants which were then in a 

 drying condition. 



Since the species may prove to be of some importance from an 

 economic standpoint it is here described and named.

Dryopea morrisoni, n. sp. 



Apterous form (Fig. 1A): Color pale yellowish with the appendages 

 slightly dusky and the eyes dark brown. Length, about 1.12 mm. Width, 

 about 0.88 mm. Body covered with rather delicate bluish white wax secreted 

 by compound wax pores arranged in six longitudinal rows on the dorsum. 

 These pores are composed of seven or eight individual pores closely grouped. 

 Antennae (fig. IB) of five subequal segments each about O.O.'JJ mm. long.
