lobes; each lateris with five rounded undulations; marginal 

 ceratubae prominent; anus five times its width from caudal 

 margin and three times from vulva. California on Cupressus, 



Sequoia. shastae Colm. 



dd. Pygidium with setae large, longer than median pair of lobes, 

 four on each side; median pair of lobes with lateral notches 

 only, rarely with mesal notch, subquadrangular, parallel or 

 somewhat convergent, longer than broad, symmetrically 

 bluntly rounded; second pair of lobes two-thirds size 

 of median, subadjacent to median, oblique, broadly rounded, 

 deep lateral notches; plates arranged 2, 1-2, 0, those of me- 

 dian incisura small, dagger-shaped, two, those of second in- 

 cisura sometimes furcapectinae, one to two; setae large, 

 longer than median lobes, four on each side. Madeira on 



Laurus. laurinus Lindgr. 



bb. Pygidium without plates in median incisura, plates in second in- 

 cisurae, and pectinae on lateres, arranged 0, 2, 2; median pair of 

 lobes large, prominent, rounded, crenulate; second pair of lobes 

 small, nearly as broad as median, mesal margin straight, lateral 

 margin oblique, crenulate, lobes inconspicuous; dorsal oracera- 

 tubae arranged in four indefinite rows on each side; anus five 

 times its width from caudal margin and same distance from vulva; 

 lateres entire; setae small; mesal calles separate, distance be- 

 tween them subequal to distance between each mesal and lateral 

 callis, latter oblique. Targionia graminellus Ckll. New Mexico, 



Colorado on ?Hilaria, Bouteloua graminellus Ckll. 



aa. Body with cephalic margin thickened and uniformly crenulate; 

 pygidium with median pair of lobes quadrangular, broad with deep 

 lateral and mesal notches, distal margin bluntly rounded; second 

 pair of lobes much smaller, pointed, large lateral notch; pectinae 

 subequal in length to median lobes, deeply lacinate, arranged 2, 2, 

 10-11, each lateris with three pectinae adjacent to second lobe and 

 7-8 short bluntly truncated plates distributed along margin of lateris. 

 This species is similar to Spinaspidiotus maeandrius Lindgr. 

 South Africa on Acioa, Strychnos. undulatus Lindgr. 



SPECIES OF PARANEWSTE'ADIA

 proximal end, spatulate, lateral notch; pectinae and plates present, ar- 

 ranged 0, 2, 7-8, those of each lateris consisting of two long simple spat- 

 ulate plates and 5-6 unapectinae, second incisura with plates. Africa.. _ 



maculata Newst. 



SPECIES OF CHORIZASPIDIOTUS 



a. Pygidium with median pair of lobes entire; quadrangular, truncate; 

 second and third pairs of lobes represented by slight deeply emargi- 

 nate projections, producing a crenulate appearance; plates and 

 pectinae wanting in median incisura and on lateres, arranged 0, 2, 

 0. New Mexico on Guterrezia guterriziae Ckll. & Parr.
