Fig. 10. Phenacoccus franseriae n. sp. : A, anal and penultimate cerarii ; B, 

 group of spines from dorsum of abdomen. 



Morphological characteristics. Adult female of the usual elongate 

 oval form ; length (flattened on slide) 4-4.25 mm. Eighteen pairs of 

 cerarii present, these for the most part with but two cerarian spines, the 

 anal pair, however (Fig. 10A), with three or four smaller spines and 

 the first two or three cephalic pairs with three. All the cerarii without 

 auxiliary setae and with few pores. Anal lobes without chitinization 

 either dorsally or ventrally, the ventral side with two slender setae. 

 Dorsal body setae few and very small except for a median group of 

 three (Fig. 10B) on the penultimate and antepenultimate segments, these 

 as large as the cerarian spines and accompanied by a cluster of pores. 

 Ventral body setae quite long and slender, with a single isolated sub- 

 marginal seta near each lateral margin of each abdominal segment. Derm 

 of the dorsum beset with numerous small trilocular pores and an occa- 

 sional small tubular duct, the three segments preceding the last each with 

 a transverse row of multilocular pores along the posterior margin. Venter
