52 THE CALIFORNIA SPECIES OF MEALY BUGS 



Also from Cupressus goveniana, southern part of Lake County ; Cupres- 

 sus macnabiana near Shasta postoffice, Shasta County; Cupressus 

 macrocarpa at Pasadena; Libocedrus decurrens, Scott Valley, Siskiyou 

 County; Sequoia sempervirens near Stanford University. 



Authentication. Specimens compared with the type by Mr. Mor- 

 rison. 



Notes : This name has ordinarily been employed for the species which must 

 stand as P. sequoiae (Coleman). Mr. Morrison's comparison of specimens with 

 the type, together with the fact that the specimens seen by me in life agree with 

 the original description, seems to establish the identity of the species satisfactorily. 

 The types of P. dudleyi (Coleman) and P. andersoni (Coleman) are at hand and 

 I can see no basis for separating them. 



This species is near P. sequoiae (Coleman), but is distinguishable in life by 

 the rather long caudal tassels and in preparations by the clustered pores of the anal 

 lobe cerarii. 



Pseudococcus salinus Ckll.

 1896. Dactylopius salinus Cockerell, Ann. Mag. Nat. Hist., (7), 9:21. 



In life. "Grey, with some white secretion, six caudal tassels and two 

 cephalic ones." (Ckll. 1896.) Found on the upper side of the leaf blades 

 of the host. 



Morphological characteristics. Apparently not more than 11 pairs 

 of cerarii present, four of these being on the head and seven at the poste- 

 rior end of the body. In the posterior seven pairs the cerarian spines of 

 the anal lobe pair are the largest, the others becoming successively smaller 

 anteriorly. First two cephalic pairs with three spines, the remainder with 

 but two. Anal lobe pair with a group of rather numerous pores, the re- 

 mainder with fewer. Auxiliary setae present in conjunction with the last 

 two pairs only. Dorsal body setae very few, small, slender. Triangular 

 pores quite numerous, mingled with a few large tubular ducts with rim 

 about the mouth. Anal ring very weakly chitinized, simple except for 

 the posterior half which is weakly chitinized and shows faint indications 

 of the usual cellular structure. Due to the chitinization of the end of the 

 alimentary canal, the ring usually presents a distinctly crescentic appear- 

 ance. The position of the ring is quite unique, inasmuch as it lies be- 

 hind the anal lobe cerarii and in all of the numerous specimens examined 

 by me appears on the ventral side of the abdomen when the specimens are 

 flattened out on the slide. Anal lobe and anal ring setae all noticeably 

 short, the former about half the length of the latter. 



Type host and locality. From grass (probably Distichlis) on the 

 cliffs at La Jolla, Calif.
