Fiorinia secreta, Green, ' Catal. of Coccidas,' Ind. Mus. Notes, Vol. IV. 



No. I (1896.) 



Female puparium consisting almost entirely of the inflated second pellicle 

 enclosed in a minute rounded gall {Jjgs. i and 5). The scale is of a peculiar 

 form {Jig. 6), pear-shaped, with the ventral and cephalic areas strongly convex, 

 and with an oblong circumscribed depression on what must be considered the 

 dorsal surface. The insect in this stage curiously resembles the pupa of a 

 Syrphid fly. Colour pale yellow, the form and colour of the contained insect 

 partially visible through the covering. Some white waxy matter usually adheres 

 to the lower ventral surface of the scale, and the cavity of the gall is im- 

 perfectly lined with a similar material. The puparium rests in an erect position 

 within the gall {fig. 5), the posterior extremity always directed towards the 

 opening on the under surface of the leaf, which is normally closed by the small 

 ochreous first pellicle {Jig. 4) ; but this latter is frequently displaced or missing, 

 possibly dislodged by the escaping larvae. The margin of the posterior ex- 

 tremity is closely fringed with fine sharply pointed thorn-like processes {Jig. 14). 

 Length 0*90 mm. Greatest transverse diameter 0*50 mm. The gall measures 

 about I mm. by 075 mm. 



Male puparium opaque white ; slightly concave above, uncarinated ; slipper- 

 shaped both in outline {Jig. 2) and longitudinal section {Jig. 3). Anterior half 

 covered by the bright yellow pellicle, which is transversely wrinkled {Jig. 2). A 

 section through the leaf at the point occupied by the puparium shows it to be 

 sunk in a depression in the substance of the leaf {Jig. 3), a corresponding 

 prominence appearing on the other side. Length 075 mm. Breadth 0*25 mm. 



Adult female {Jigs. 7 and 8) bright yellow, with inconspicuous blackish eye- 

 spots on the anterior margin. A median longitudinal section through the 

 pear-shaped second pellicle will show the adult female resting loosely inside 

 in an erect position {Jig. 13). Thoracic segments broadly rounded and strongly 

 convex dorsally ; abdominal segments suddenly narrowed and tapering to a 

 point. Antennas minute, rudimentary, situate on the anterior margin, two- 

 jointed, terminal joint a small conical tubercle, basal joint a flattish oval plate 

 with a stout curved hair on one side {Jig. 9). Spiracles elevated on small round 

 tubercles {Jig. 8). Pygidium long and narrow, terminating in a conspicuous 

 prominent narrow median process, which is dilated and indented at the apex 

 {_fig. 10) ; the lateral margin near the extremity is very irregularly and variously 

 crenulate or dentate, the two sides being often asymmetrical {Jigs. 10, 11, 12). 

 There are no true lobes, squames, or spires ; no circumgenital glands, and no 

 tubular spinnerets. The surface of the pygidium is longitudinally marked with 

 numerous fine lines and wrinkles. Genital aperture close to base of pygidium ;
