A NEW MEALY BUG

Description of Pseudococcus bakeri, □. sp. 



Adult Female. (Fig. 126.) The general shape of the adult female 

 is rounded oval. Length of body 4 to 6 mm., width 2 to 3 mm. The 

 covering consists of a rather thick white, powdery way which hides the dark 

 body, but which is not thick enough to conceal the distinct body segmentation. 

 The lateral wax appendages are from 1 to 2 mm. long and very slender — 

 much narrower than the width of the supporting body segment. The ana! 

 wax appendages are from one-half to two-thirds the length of the insect body. 



When boiled in KOH the contents of the body become cardinal, but, 

 when all of the excreta is removed, the internal organs become light yellow 

 or amber in color, while the body wall appears perfectly transparent and color- 

 less.
