Fig-. lA, C-F. 



_Material examined. — Guarscia, Cyrenaica. without indication 



of iiost. 



Habit. — As far as may be judged from the morphology of the 

 species it will, in life, very much resemble P. citri, iiaving very short 

 marginal" and caudal tassels. 



Morphology. — Form, when flattened on the slide, approaching 

 sub-cir(iular. Length 2-2,5 mm. With 17 pairs of cerarli, each of which

 Pseudococcs citrioides n. up.: A, posterior portion of abdomen, left side dorsal, right 

 Bide ventral: C, antenna; D. ventral side of anal lobe, more enlarged; E, cerarian setae 

 of anal lobes; F, cerarian setae of pre-anteunal cerarli. Pseudococcus lilactnus Ckll. 

 (specimens from Philippine IsLauds); B. cerarian setae of abdomen, with supplementary 

 marginal seta; (i, cerarian setae of pre-antennal cerarius. 



contains but two small cerarian setae accompanied by a very few pores 

 and without auxiliary setae. Cerarian setae of the anal lobe pair (Fig. 1 E) 

 quite slender, those of the other pairs becoming smaller toward the 

 head where they are extremely small and almost filiform (Fig. 1 F). 

 Anal lobes (Fig. 1 A) without chitinization above, but with a small, 

 but very definite, chitinized bar (Fig. 1 D) on the ventral side exten- 

 ding in from the base of the anal lobe seta; dorsal side of the lobes 

 with a few very small setae, the ventral side wHh two slender, sub- 

 apical setae. Dorsal body setae few, small, slender. Ventral body setae 

 more numerous, of varying lengths but none conspicuously long except 

 a single sub-marginal seta near each abdominal cerarius. Triangular
