Hosts and distribution. Known only from the above host and lo- 

 cality. 



Authentication. Topotype specimens examined. 



Puto cupressi (Coleman). 



1901. Dactylopius sequoiae Coleman, Proc. Calif. Acad. Sci., (3), 2:410, fig. 



(As to male.) 

 1908. Pseudococcus cupressi Coleman, Jn. N. Y. Ent. Soc. 16:197-8, pi. 4, figs. 1-4. 



In life. Adult female reaching the length of 6 mm. ; dorsally bare 

 of secretion except for a dusting of fine powder ; with very short, stout, 

 lateral tassels and with a somewhat longer caudal pair. Dorsum of a 

 light brown color, with marginal and submedian longitudinal rows of 

 dark spots. Ovisac more or less pad-like. Oviparous. 



Morphological characteristics. Adult female with 8-segmented an- 

 tennae. The fundamental arrangement of 18 pairs of cerarii (indicated 

 in the first stage larva) is obscured by the presence of small secondary 

 cerarii and occasionally by the more or less complete suppression of cer- 

 tain of the cerarii. Chitinous areas surrounding the cerarii for the most 

 part rather small, the number of cerarian spines ranging from 5-12, the 

 anal lobe area being much larger than any of the others and being con- 

 tinuous with a small chitinized area on the ventral side of the anal lobes. 

 Dorsum with few spines, these short and conical. Anal ring with 8 hairs 

 (in the adult), one pair of these being considerably smaller than the 

 others. 



Immature female with 7-segmented antennae and with the chitinized 

 areas of the cerarii smaller than in the adult. The first stage larva pos- 

 sesses 7-segmented antennae. In all the immature stages of both male 

 and female I find but six anal ring setae. The male prepupa is enclosed 

 in a conspicuous white sac. 



Adult male winged, with a wing expanse of 8 mm., of the type usual 

 to the genus. 



Type host and locality. From Cupressus macrocarpa, Cypress Point, 

 Monterey County, Calif. 



Hosts and distribution. From Pinus radiata, Pacific Grove ; Torreya 

 calif ornica, Stevens Creek, Santa Clara County (Ehrhorn, coll.) ; Se- 

 quoia sempervirens, vicinity Stanford University. At Pacific Grove and 

 Cypress Point the species becomes mature in December and January, in 

 the vicinity of Stanford University adult females are not found until May 

 and June. 



Authentication. Cotype and topotype specimens examined, the for- 

 mer through the courtesy of Mr. Ehrhorn.
