TIJE COCCIDAK OF CALIFORNIA. .")! 



anterior group 4-"), })osterior group 5-6; fourth row, anterior group 4-6, 

 posterior group 6-8. Mesad of second and third lobes respectively is an 

 elongated pore, appearing like a lobe. Anterior group of circumgenital 

 gland-orifices distinct, rounded, 18-22; anterior laterals, 25-32; pos- 

 terior laterals, 26-34. Lateral groups indistinctly separated, sometimes 

 almost continuous. 



On rose, blackberry, and raspberry, infesting the canes. 



This is a very common species in this State, and may be found on old 

 rose bushes, and on the canes of blackberry and raspberry. In many 

 cases it entirely coats the cane for some distance, giving it the appear- 

 ance of having been whitewashed. When remedial measures are applied 

 and all visible scale removed the horticulturist is somewhat surprised 

 to again see the plant infested in a short time, owing to the fact that 

 this species breed at or near the root of the host plant. When remedial 

 measures are applied, the ground should be removed from around the 

 base of the plant so that the wash will reach all the scale. 



Hemichionaspis aspidistrse Sign. 

 E'jgs. — Reddish falvous. Larva. — ^Pale yellow (newly hatched). 



Scale of Female. — Length, 1.8 to 2.6 mm. Distinctly broadened pos- 

 teriorly and usually broadly rounded at the extremity, but occasion- 

 ally bluntly pointed. Very thin and delicate in tissue or moderately 

 thick and strong. Pale yellowish brown to brown. Exuivia^ .7 to .9 mm. 

 long, of the same color as the secreted portion of the scale, but slightly 

 brighter. 



Femile. — The first four segments anterior to the pygidium very pro- 

 nounced, being often produced at each side into a conspicuous protu- 

 berance. The first and second pairs of lobes well developed, third very 

 rudimentary or wanting. Each median lobe with three distinct notches 

 on the outer curved edge. Lobules of the second lobe long and narrow, 

 spatulate in form; edges thickened at the base. The gland-spines are 

 arranged as follows: 1,1,1,1,2-5. As a rule the fifth group contains- 

 2-3 spines, although 5 have been observed. The marginal gland - 

 orifices between the first and second lobes, if situated on a large, con 

 spicuous prominence. Second row of gland-orifices wholly absent. 

 Third and fourth rows with 2-5 orifices in their posterior groups. An- 

 terior groups absent. Median group of circumgenital gland-orifices, 

 5-15; anterior laterals, 15-22; posterior laterals, 17-23. 



Scale of Male. — Length, I to 1.3 mm. Exuviae bright yellow.
