Morphological characteristics. Adult female (Fig. 7A) (on slide) 

 about 2.5 mm. long, regularly oval. Derm slightly pigmented. Dorsum 

 destitute of all but a few very small, slender spines. Venter with a trans- 

 verse row of small, slender setae on each abdominal segment and a few

such setae on the thorax. Anal lobes low, each with one long and one 

 short seta. Anal ring (Fig. 7D) distinctly cellular, bearing six setae 

 which are somewhat longer than the diameter of the ring. Derm beset 

 with numerous small, multilocular pores, both dorsally and ventrally, 

 especially on the abdomen. Antennae (Fig. 7C) 7-segmented, moderately 

 stout. Legs quite slender, the claw with a very minute denticle. Spiracles 

 small, not surrounded by a ring of pores. Wax ducts (Fig. 6B) with the 

 cup quite deep, slightly asymmetrical. 



Immature stages not seen. 



Notes: This is the third species of this genus to be recorded from North 

 America. It is very distinct from F. yuccae Ferris, and F. braggi Ckll. and Rob., 

 the cellular anal ring and the absence of pores about the spiracles serving to 

 distinguish it at once.
