THE COCCIDAE OF SOUTHWESTERN UNITED STATES 55 



Female. Length .8 mm. Cephalothorax (Fig. 28) heavily chitin- 

 ized dorsally. Semicircular in form, much exceeding the abdomen in 

 width. Abdomen membranous or but slightly chitinized ; dorsum of each 

 segment with a submedian group of small, tubular ducts, last two or three 

 segments anterior to the pygidium with a few ducts near the lateral mar- 

 gin. On the ventral side the last three segments anterior to the pygidium 

 bear many small ducts near the margins. 



Fig. 29. Pseudodiaspis condaliae n. sp. : pygidium. 



Pygidium (Fig. 29) with the median lobes alone well developed, 

 these broad and low, with the tips rounded, notched laterally. At each 

 basal angle is a very small spine. A much larger spine marks the posi- 

 tion of the obsolete second and third lobes. Between the first lobe and 

 the position of the second is a single low gland prominence and just 

 beyond the second lobe is a gland spine or plate. Anal opening small, 

 quite near the posterior margin. Dorsal and marginal ducts of practi- 

 cally the same size, arranged as indicated in the figure. On the ventral 

 side the spines are all quite small and there are four small, heavily chi- 

 tinized areas extending in from the margin and bearing several small, 

 tubular ducts. Vaginal orifice set in a depressed area. 



Notes : The peculiar form of the female is alone sufficient to separate this 

 species from the others here referred to this genus.
