THE COCCIDAE OF CALIFORNIA. 



49 



from 10 to 16, and the posterior laterals of about 8. There are four lobes, 

 which are nearly in a straight line, the end of the body -being truncate- 

 These lobes are quite small, rounded posteriorly and equally distant 

 from each other. The second lobe of each side is deeply incised, but the 

 lateral lobule is very small, and in many cases concealed by the margin 

 of the segment. Each lateral margin of the segment is divided into 

 three subequal, more or less distinct 

 lobes; each lobe ends posteriorly in one 

 or more lobules, each of which bears an 

 elongated pore on its dorsal surface. The 

 plates are short, and in some cases sub- 

 truncate at extremities; they are situated 

 as follows: Two between median lobes; 

 two inconspicuous ones laterad of first 

 lobe of each side; two laterad of second 

 lobe; usually one on the anterior part 

 of the first lobe of the lateral margin; 

 one or two near the middle of the second 

 lobe of the lateral margin, and two or 

 three on the third or anterior lobe of 

 the lateral margin. Dorsal spines: One 

 on first lobe near lateral margin; one on 

 lateral lobule of second lobe; and one a 

 short distance mesad of the mesal plate 

 of each of the three lobes of lateral mar- 

 gin. The ventral spines accompanying 

 the first and second lobes of each side are 

 obsolete. There is one at the base of 

 the plate of the first lobe of the lateral 

 margin; one between plates of second lobe, and one near the middle of 

 the third or anterior lobe of the lateral margin. 



Scale of Male. The male scale is white, and. very small, being only 

 1 mm. in length; it is elongated, with a prominent median ridge; the 

 larval skin is naked and light yellow in color. 



Male. Color of body light orange yellow, thoracic band yellow. The 

 terminal joints of the antennae are enlarged. 



On juniper (Cupressus sp.). 



In several sections this scale may be found very abundant upon 

 juniper, but seems to confine its attack to this host plant and Cuprestus 

 sp. It is not considered as troublesome.
