THE COCCIDAE OP SOUTH AFRICA. — III. 221 



Genus Fiorinia, Targ. 



The scale of the adult $ is generally extremely thin and transparent, revealing 

 the large, hardened, second stage skin, which entirely encloses the adult $. The 

 colour of the scale is thus determined chiefly by the colour of the dry second stage 

 skin. 



The adult $ is smaller than the enveloping skin, and gradually shrinks as eggs 

 or young are deposited within the same hardened case.

Scale of adult $ about 1"25 mm. long and 0"5 mm. broad, consisting almost 

 entirely of the second pellicle covered by a thin transparent layer of colourless 

 secretion, which extends slightly beyond its margin. Colour of the second pellicle 

 varying from orange-yellow to rich reddish-brown. The median line is generally 

 somewhat raised into a rounded longitudinal ridge, which appears darker. The 

 first exuviae are small, pale in colour, and extend beyond the margin of the anterior 

 extremity. 



Male puparium white, about 1 mm. long and 0"4 mm. broad, straight, distinctly 

 tricarinate, with pale yellow exuviae. 



Adult $ dull orange-yellow in colour, at first elongate, later with abdominal 

 segments somewhat retracted. 



"Female thin and much contracted after oviposition, elongate, possessing 

 rudimentar3 r antennae, which are apparently two-jointed, the first consisting of a 

 fleshy tubercle, which bears the second joint and a bristle, the second joint occasionally 

 possessing a short lateral branch near the tip ; anal plate triangular, 0"187 to 

 - 204 mm. in width, slightly truncate at tip, median notch distinct and formed 

 by the median lobes, which are oblique and serrated along their entire free edge ; 

 second lobes prominent both in second larval exuviae and adult, incised, about twice , 

 as long as broad and followed by several indentations ; margin of the pygidium 

 exhibiting four rather conspicuous tubular pores ; between the median lobes are 

 two short spines ; located on the dorsal surface situated along the lateral margin 

 of the median lobe there are two spines, the posterior being the larger, one on the 

 outer lobule of the second lobe and two situated between the second lobe and the 

 penultimate segment ; on ventral surface there is a spine corresponding with each 

 dorsal spine, except on the first lobe ; laterad of each lobe there is an elongate pore 

 and two between the second lobule and the penultimate segment ; anal opening
