THE COCCIDAE OF SOUTH AFRICA— II. 123 



insects mounted no single specimen shows them all in position. L x small, deeply 

 recessed, + parallel- sided and notched on each side. L 2 large, rounded, outer portion 

 not conspicuously notched, but striate. L 3 smaller than L 2 , roundly pointed, with 

 the apex pointing slightly outward. P comparatively short. P x and P 2 not so 

 long as L 2 . P 3 fringed on the outer margins. Pygidium as illustrated (fig. 86). 



Formula : P 15 L 1; 2P 2 , L 2 , 2P 3 , L 3 . 



Adult <J not observed. 



This insect is most like Aspidiotus excisus, Green, in the peculiar type of pygidium. 

 It is readily distinguished from that species however by (a) the difference in the scale, 

 (b) the fact that the median lobes are smaller than the second pair, and (c) the entire 

 absence of circumgenital glands. 



The material studied consists of a small collection of dry material from which 

 8 adult females were mounted. 



Habitat : On grass (Andropogon amplectens, Nees), Meintjes Kop, Pretoria ; 

 collected by A. Kelly, October 1913 ; also in same place by Carl Rudolf, 8th April 1916. 



I have much pleasure in associating the collector's name with this species as a token 

 of appreciation for much assistance rendered in a multitude of ways. 



Collection No. : B188. 



76. Aspidiotus gowdeyi, Newstead (Plate vi, fig. 87). 



Aspidiotus gowdeyi, Newst., Bull. Ent. Res. iv, p. 77, 1913. 



Scale of adult $ " very small, obconical and suddenly truncate at the margin of 

 the larval pellicle ; margin circular. Colour dark brown, outer margin paler, upper 

 margin orange-brown to pale castaneous. Larval pellicle completely hidden beneath 

 a glistening white secretion, which is perfectly flat, quite circular in outline, and 

 not raised above the upper truncate margin of the secretionary covering of the 

 puparium. Ventral pellicle thin. Diameter, 0"4-0"5 mm. 



" Female, adult. Broadly ovate, narrowed posteriorly ; integument very thin 

 and transparent ; presence of rudimentary antennae and parastigmatic glands 

 doubtful. Pygidium with six lobes ; median lobes much the largest, distal margin 

 broadly rounded ; second and third pair small and somewhat triangular, with the 

 distal margins more or less pointed. Squamae very finely and closely fringed ; those 

 between the median and third pair of lobes and the three succeeding ones, on either 

 side, unusually broad, the two proximal ones small and branched. Only two spines 

 are traceable and these are placed on opposite sides beyond the squamae. There 

 is a very small bilateral incision near the second pair of lobes and a rather long 

 thickening of the integument near each of the third lobes. Anal orifice large and 

 submarginal. Position of the vaginal orifice rendered obscure by a large and 

 somewhat tongue-shaped thickening of the integument occupying the middle area 

 of the pygidium. Circumgenital glands absent." (Newstead). 



Pygidium as illustrated (fig. 87). 



Formula : P 1; L v 2P 2 , L 2 , 3P 3 , L 3 , 6-8P 4 . 



Habitat : On " umkavoti " (Chaetachme aristata, Planch.) and other native shrubs 

 in Natal and S.E. Cape Province.
