54 A CONTRIBUTION TO THE KNOWLEDGE OF 



thickening. Between the median lobes and the position of the second 

 pair is a single gland spine or prominence and just beyond the second 

 lobe is another such prominence. Dorsal tubular ducts of practically the 

 same size as those at the margin, few. The distribution of the ducts 

 may best be determined from the figure. Anal opening very small, close 

 to the posterior margin. On the ventral side the spines are all extremely 

 small. Vaginal orifice situated in a depression as indicated by the figure. 



Notes: I am inclined to regard this species as most closely related to the 

 species which has stood as Targionia parkinsoniae (Ckll.) and which I am rede- 

 scribing below.

Type host and locality. From Condalia spathulata, Tucson, Ariz. 



Scale. Scale of female circular, rather high convex, with the exu- 

 viae central or sub-central ; first exuvium naked, second covered by secre- 

 tion; ventral scale extremely thick at the margins, thinner in the center. 

 Color of the scale light brown. Scale of male resembling that of female 

 in color and texture, oblong, with the sides more or less parallel; with 

 the exuvium near one end.
