In one instance the fifth group is represented by a single gland. Anal orifice 

 immediately below the posterior-lateral groups of circumgenital glands. Above the 

 the grouped glands a narrow transverse thickening of the derm, which may be entire 

 or divided into three parts : a median and two lateral. Margin of pygidium (fig. 22) 

 with three pairs of lobes, all of which are relatively broad ; the third pair the largest ; 

 distal margins irregularly and faintly dentate or serrate. Beyond the lobes the 

 margin is thickened and projecting, with minute serrations and, usually, six deep 

 indentations. In some examples the lobes and serrated projections of the margin are 

 so continuous that it is somewhat difficult to determine where the one begins and the 

 other ends. The ducts which lead to the spaces between the lobes are fourteen in 

 number, of which four are much longer than the rest ; each wath a distinct knob- 

 like terminal. Squamae, when present, exceedingly minute ; these were traced with 

 difficulty, between the lobes, in a few instances only.

Nearly allied to A. scutiformis, Ckll., and A. kelloggii, Ku., but difEers in the form 

 knd arrangement of the pygidial appendages, the club-shaped ducts, and the 

 circmngenital glands. 



Aspidiotus (Evaspidiotus) fimbriatus, Mask, var. capensis, var. n. 



Female, adult. Differing from typical Aspidiotus fimbriatus in having much more 

 deeply fringed squamae to the margin of the pygidium (fig. 23, a) and fewer
