Fig. 67. — Anatomical details of the camellia scale, Pulvinaria floccifera 

 (Westw.). a, antenna; b, tarsus; c, breathing spines along the margin of the 

 body ; d, leg ; e, simple and branched spine-like hairs on the body ; f, anal-valves 

 and spines. Enlarged. (Original.) 



So far control measures hav3 never been found necessary. Oil 

 emulsions and miscible oils will readily kill the immature forms during 

 the winter months, and in cases of severe infestations should be used at 

 that time.
