With a short, stout lateral spine, sometimes annulated, a little anterior 



to cephalothoracic suture (cephalothoracic section usually largest). 



With prominent chitinized spur laterad of second lobe on edge of 



pygidium. 



Paragenitals in two compact groups of 6 to 7 pores each ; adult 



female not exceeding 1.5 mm. long....i. articulatus Morgan. 



Paragenitals in four scattering groups of 6 to 9 pores each ; 



adult female 1.5 to 2 mm. long, 



2. articulatus, var. celastri Maskell.

 paragenitals present. 

 Dorsal pores large, numerous, in rows radiating from tip 

 and sides of pygidium; lattice patch distinctly de- 

 veloped. 

 Median lobes projecting distinctly beyond laterals; 

 lateral lobes very slender, less than one-fourth the 

 width of median lobes ; paragenitals 20 to 50 pores 

 in each group; stigmatic pores 13 to 25,
