(Plate XIX., Fig. 28.) 
Adult 2 has the appearance of Ps. citri ; the median dorsal stripe, 
secretion, and filaments as in that species. 
The completed ovisac was in every case slightly covering the caudal 
extremity of the insect. Ovisac loosely constructed, cottony, irregularly 
oval in outline. 
Antennae normally 9-segmented ; one insect has its antennae 
8-segmented, in one of which a distinct pseudo-articulation is visible. 
Mounted specimens are about 3 mm. in length. 
Range of measurement of antennal segments : — (1) 46-52 ; (2) 61-68 ; 
(3) 61-65 ; (4) 34-38 ; (5) 37-47 ; (6) 37-44 ; (7) 47-52 ; (8) 44-47 ; (9) 
60-68.

for citri including 8 + 9 for the terminal joint of that species.
