PSETIDOCOCCUS WALKERI Newst. 



I have foimd this interesting species somewhat commonly in the 

 Camberley district, and can confiiTu Prof. New stead's observation 

 (Mon. Brit. Cocc, Part II, p. 171) that " on the slightest disturbance 

 they fall to the ground, and are then veiy active." 



PSEITDOCOCCUS, Sp. 



A window pane is not a situation in which one would expect to 

 collect Cocci dae ; but Mr. Hugh Scott has sent me specimens of the 

 minute winged males of a species of Pseudococc2is (possibly cifri) — 

 " part of a large number of individuals which appeared on the window 

 of a house (at Torquay) in September, 1913." The room was on the 

 ground floor, and the window opened on to the garden.
