NOTES ON CALIFORNIA COCCID/E V 



219 



The antennae (Fig. 93 A) are /-articled and normally placed on the 

 head. They are very distinctly seen with the unaided eye in some specimens. 

 Many specimens were examined with three normal ones drawn and showing 

 the following formula: : 



One specimen — 7, (1, 2, 4), 6, S, 3. 

 One specimen — 7, 1, (2, 4), 6, 5, 3. 

 One specimen — 7, (1, 2), 6, 4, 5, 3. 



The antennjE on the same specimen usually agree, but these often differ to 

 a marked degree. 



Figure 93. Ripersia smithii. 



Legs (Fig. 93 C) — Normal, with few hairs. Coxa large and as long as 

 the tibia. Femur longer than tibia. Tibia one-third times the length of the 

 tarsus. Claw normally curved. 



Pygidium (Fig. 93, D and E) — Normal with six anal spines. In one 

 specimen there was a spine just before the anal opening (Fig. 93 E). This is 

 not usually present. Lobes not prominent — with no spines in adult form — a 

 few short hairs. In the young there are two short stout spines and several hairs 

 forming a sort of tuft. The ventral surface has very few hairs or spines. The 

 dorsal surface has many hairs and two long lateral hairs or spines, these appear 

 on the lobes of the younger forms.
