FIORINIA SCROBICULARUM, Green. 



(Plate XXIX.) 



Fiorinia scrobicularum, Green, ' Catal. of Coccidte,' Indian Mus. Notes, 

 Vol. IV. No. I (1896). 



Female puparium {Jigs. 4 and 10) elongate, narrow in front, broadening 

 behind ; posterior half rather abruptly depressed, the large second pellicle 

 covered by a very thin layer of secretion which scarcely projects beyond the 

 margin. Colour pale yellow, median area tinged with reddish, the adult female 

 indistinctly visible through the scale. First pellicle long and narrow. Length 

 I mm. Greatest breadth o"3o mm. 



Male puparium {fig. 2) opaque white with the pellicle pale yellow, elongate, 

 narrow, uncarinated, hinder part flattened, surrounded by some loose white 

 flocculent secretion which projects from the mouth of the cavity in which the 

 scale is concealed {Jig. 3). Length ri5 mm. 



Adult female {Jigs. 5, 6, and 7) elongate, narrower in front, abdominal 

 segments widest ; division of segments rather indistinct. Body rather thick 

 dorso-laterally, the tumescence ending abruptly at the base of the pygidium, 

 which is thin and deflexed {Jig. 7). Small blackish eyespots are indistinctly 

 visible on the anterior dorsal margin in living examples. Antennce {fig. 8) of 

 two short joints with a stout bristle on the side of the basal joint. No marginal 

 tubercles. Pygidium {Jig. 9) triangular, extremity with a deep median notch, 

 on the sides of which are the small oblique median lobes, followed closely by 

 two small prominent marginal points representing the lateral lobes. There are 

 three small indentations on the lateral margins, and three or four small spines. 

 Circumgenital glands in five distinct groups, the median with four to six orifices, 

 upper laterals with seven to eleven, and lower laterals with seven to thirteen. 

 Tubular spinnerets cylindrical, rather inconspicuous, three on each side, opening 

 on to the margin. Anal aperture considerably anterior to the genital opening, 

 almost on a level with the median group of glands. Length o"6o mm. 



Adult male not observed. 



Eggs pale yellow, comparatively large, almost a quarter the size of the parent 

 insect. 



Habitat : — In the glandular pockets (scrobiculs) at the angles of the veins 

 on the under surface of the leaves of GcErtirera Koenigii, Punduloya (July). 

 The female scales are completely concealed, but their presence may be detected 

 by a yellowish discolouration on the upper surface of the leaf immediately above 

 the affected part. The male scale is only partially concealed. The small white 

 spots at the angles of the veins of the leaf {Jig. i) mark the position of the male 

 insects. A very small and inconspicuous species, unlike any of its congeners. 

 The relatively large size of the male scale, which is longer than that of the 

 female, is unusual.
