1912] Pseudococcus of South Africa 185 
Larve: (a) newly hatched, orange yellow, legs and antennz pale, 
transparent. The larve in this stage are very active, oval in form, 
measuring 358 uw long by 170 uw broad. (b) later, 544 uw long by 255 u 
broad. Antenne of 6 joints, about 170 uw long. Eyes conspicuous, black. 
Measurements of the larval antennz in w gave the following lengths for 
the segments: 20, 22, 16, 18, 20 and 68 w. Larve began to emerge from 
ovisacs kept at room temperature on October 25th. 
Male: not found. 
Adult 9 : (Plate XIV, Fig. 2) small; largest specimen, with completed 
ovisac, was 1.9 mm. long by 1.13 mm. broad, slatey-gray in color; waxy 
secretion scant but segmentation conspicuous. Lateral appendages 
were absent but usually four caudal ones present, the longest of which 
measured 330 uw. Color in boiling K O H black, then purple.

Plate XVI, Fig. 5, shows the distribution of spines, etc., round anal 
lobes. 
Type Slide: This slide has two specimens mounted on it, but the 
one to the left as slide is labeled is considered the type specimen. 
(Specimen A). 
Specimen A: Size mounted 1.6 mm. by 1.14 mm. 
Dermis: Pores very scattered. Those on the dorsal surface gener- 
ally larger than those of ventral surface. On both surfaces are a few 
scattered hairs. Some of these on the dorsal surface, towards the 
anterior end are long and very slender, reaching in a few cases 90 u long. 
Antenne: Right—34?, 34, 26, 20, 24, 20, 25 and 78 yw. Left—40, 
35, 26, 16, 24, 20, 25, and 80u . 
The setz of the anal lobes are 128 uw long, while those of the anal 
ring average about 112 uw.
