Egg — Oblong and white; length about 0.27 mm; width, 0.16 

 nun. 



First larval stage — Oval in outline ; pale yellow^ in color, with 

 eyes black. Antennae six-segmented, segment III the longest.

This new species is allied to Pulvinaria thespesice Green, but 

 much smaller and distinguished by the shape of the triangular 

 l)lates; in this species the outer angle of the triangular plate is 

 irregular, while that in P. tliespesicp is broadly rounded. Ditfers 

 also in the relative length of antennal segments.

 and many cross ridges. Antennae usually eight-segmented, but 

 seldom only seven; segment III the longest; all segments bear 

 rather long hairs ; formula of four examples as follows :

 Mouth parts well formed; rostral setae rather long. Legs 

 stout, subequal; coxa much longer than wide; trochanter with 

 one long and few short hairs; femur about equal with tibia in 

 length; tarsus shorter than one-half of tibia; claw short and 

 curved; digitules rather short. Marginal hairs simple; stig- 

 matic cleft shallow with three usual spines, of which the median 

 one is very long. Derm with scattered small circular cells. 

 Triangular plates very prominent ; inner edge longest ; base and 

 outer edge about equal; apex bluntly pointed; outer edge 

 slightly curved; apex with several spines. 



Diameter about 4-7 mm. ; length with ovisac, 8-10 mm. ;
