64 THE CALIFORNIA SPECIES OF MEALY BUGS 



Notes : It has been proven beyond any room for doubt that the male de- 

 scribed by Coleman under Dactylopius sequoiae does not belong with the female 

 of that species. Neither is there any doubt that this male is the same as that 

 described by the same author under Pseudococcus cupressi. This species is of 

 much interest, inasmuch as it effectually unites the two genera Puto and Ceroputo.

In life. Thickly covered with white wax; with short, stout lateral 

 tassels, the caudal tassels being somewhat longer. Length 4-6 mm. Male 

 pupa contained in a white cocoon of 3-4 mm. length. Adult male winged, 

 with a wing expanse of 7-8 mm. and with a pair of caudal wax tassels 

 as much as 6 mm. long. 



Morphological characteristics. Antennae of the adult female 9-seg- 

 mented. Antennae and legs strongly chitinous. Cerarii varying in num- 

 ber from 15 to 18, each surrounded by a chitinous area, each containing 

 a dozen or more short, conical spines and a somewhat smaller number of 

 pores. Anal lobe area largest. No chitinized area on the ventral side 

 of the anal lobes. Dorsum with small, scattered, conical spines. Anal 

 ring with six setae, very rarely with eight. 



Immature female resembling the adult except for the smaller size of 

 the chitinized areas. First stage larva with 7-segmented antennae. 



Type host and locality. From Yucca whipplei, Los Angeles County, 

 Calif. 



Hosts and distribution. Recorded from several species of yucca, 

 from Diplacus glutinosus, Ramona polystachya, citrus and bananas in the 

 southern part of the state. In the vicinity of Stanford University I have 

 taken the species from Eriophyllum confertiflorum, Diplacus glutinosus, 

 Garry a elliptica and Stachys sp. 



Authentication. Not authenticated. Specimens from the type region 

 have been examined which agree with the original description and which 

 belong to a species that has generally been accepted as P. yuccae (Coq.). 



Notes: I have examined topotypic specimens of Ceroputo bahiae (Ehrh.) 

 and can find no basis upon which to separate this from Puto yuccae. The variety
