SCALE INSECTS OF SANTA CRUZ PENINSULA 



side. On the cephalothorax the spines are more numerous and are irreg- 

 ularly arranged. Anal lobes (Fig. 7E~] weakly chitinized, each with 

 three slender setae on the ventral side and three spines on the dorsal side 

 which are of the same shape as the body spines. Antennae (Fig. 7C) 

 rather stout, 6-segmented, the third segment being very long. Legs 

 rather slender, the claw with a very small tooth, the posterior coxae 

 without pores. Ducts (Fig. 7D) with a rather broad and shallow cup. 

 Anal ring with eight setae which are about half as long as the anal lobe 

 setae. 



Notes : I have but a single specimen of this species from this locality. Cer- 

 tain specimens from Chamaecyce polycarpa between Mecca and Blythe, Riverside 

 County, Calif., resemble it in the arrangement of the spines and in the character 

 of the antennae but differ in having the spines smaller and blunter. I am inclined 

 to refer them to this species.

Type host and locality. From Eriogonum latifolium, New Year's 

 Point, Santa Clara County, California, September, 1918. 



Sac slightly yellowish, its surface with many projecting filaments of 

 wax. All the specimens observed were on the under surface of the leaves, 

 the color and roughness of the sac causing them to resemble very closely 

 the thick tomentum of the leaf.
