38 THE CALIFORNIA SPECIES OF MEALY BUGS 



17. With a chitinized area on the ventral side of the anal 



lobes comstocki (Kuw.) 



Without such a structure quercicolus n. sp. 



18. Pores of the anal lobe cerarii arranged in a crowded, 



circular group longispinus (Targ.) 



Pores of the anal lobe cerarii scattered 



citrophilus (Claussen) 



Pseudococcus affinis (Maskell). 



1914. Pseudococcus affinis (Maskell) ; Essig, Mon. Bull. Calif. State Com. Hort. 



3:106. 



Essig states that the U. S. Dept. of Agriculture has recorded this 

 species as attacking Anemone sp. in California. However, there is no 

 other record of its occurrence in the state and it is not considered in the 

 present paper. 



Pseudococcus aurilanatus (Maskell). 



1889. Dactylopius aurilanatus Maskell, Trans. New Zealand Inst. 11:151. 



1915. Pseudococcus aurilanatus (Mask.) ; Essig, Inj. & Benef. Ins. Calif., 2d ed., 



125, fig. 106. 



In life. Of a deep red or purple color, the waxy secretion of a 

 bright yellow color and arranged in tufts on the dorsum and along the 

 margins. Ovisac short, quite firm, white. 



Morphological characteristics. Body contents black; derm blue- 

 green; cerarii present on the last five or six abdominal segments only, 

 each with two cerarian spines, those in the anteriormost pairs are so small 

 and so widely separated as to be scarcely recognizable. Anal lobe cerarii 

 surrounded by a small, indefinite, chitinized area and accompanied by 

 two or three slender setae and a few pores. Remaining cerarii with 

 neither grouped pores nor auxiliary setae. Dorsal body setae small, con- 

 ical, somewhat constricted at the base, scattered, few in number except 

 on the head. Tubular ducts few, very small, without a raised rim about 

 the mouth. Anal lobe setae about equal to the anal ring setae. Antennae 

 7-8-segmented. 



Type host and locality. From Araucaria in Australia. 



Host and distribution. Essig states that this species occurs on dif- 

 ferent species of Agathis as well as on Araucaria. Its out-of-door range 

 in this state is not definitely known, but it occurs on Araucaria out of 

 doors at Mountain View in Santa Clara County. 



Authentication. Not authenticated. Agrees with original descrip- 

 tion. 



Notes: In many respects this species departs rather widely from typical 

 Pseudococcus and in part it is morphologically much nearer Erium or even Tri- 

 onymus. I shall not, however, attempt to remove it from Pseudococcus.
