14. PSEUDOCOCCUS BECHUANAE Sp. n. 
On December 4, 1914, mealy-bug material was received from 
Vryburg, Bechuanaland, accompanied by a letter stating that the insect 
was a great pest on geraniums. 
The specimens had been badly shaken in the post, but it was clear that 
large patches of the stem had been completely covered with ovisacs. The 
white secretion appeared powdery rather than cottony. 
The females embedded in this were pinkish in colour when young, but 
purplish in older specimens. There were no lateral filaments, and only 
two short, blunt, caudal ones. The female when adult reaches approxi- 
mately 3 mm. in length. In boiling NaOH the insect becomes very dark 
purple, almost black, while the liquid is stained but very slightly. 
When cleared and mounted the most striking character is the absence 
of marginal spine areas, and the presence of scattered gland-pores of two 
sizes. The small ones are by far the more numerous ; the larger ones 
have subcuticular tubes which are swollen inwardly. One of these always 
takes the place of the marginal spine areas, and there are often trans- 
verse lines of such across the middles of the segments. 
The antennae are always 8-jointed, with 8 showing a pseudo-articulation 
in a few cases. The range of measurements of the segments is : — (1) 
46-52; (2) 58-68; (3) 54-64; (4) 27-34; (5) 34; (6) 20-24; (7) 27-32; 
(8) 74-85.
