Aspidiotus. 53 



ASPIDIOTUS EXCISUS, sp. nov. 

 (Plate X. figs. 7-9.) 



Female puparium {fig. 8) convex, of irregular outline, margin often lobed, 

 thin, and semi-transparent, whitish or very pale ochreous ; bearing many long 

 hairs, which have been separated from the plant and incorporated into the scale. 

 Pellicles yellow, approximately central. Ventral scale obsolete. Diameter 

 about I mm. 



Male puparium {fig. 7) smaller and more oblong, similar in structure to that 

 of female. Size, o'8o by 0*50 mm. 



Adult female yellow ; broadly pyriform. No parastigmatic glands. Pygidium 

 {fig. 9) appearing truncate from the fact that the extremity is broadly and deeply 

 excised. Lobes six ; median pair largest, but sunk in a deep, squarely cut 

 recess, which extends on each side as far as the second lobe, their distal 

 extremities plain or very slightly emarginate and slanting ; second and third 

 lobes small but prominent, the second projecting distinctly beyond the mesal 

 lobes. Squames deeply fringed, two in the mesal and first spaces, three in the 

 second space, and four beyond the third lobe. Small spines at base of each 

 lobe, and three at intervals along the lateral margin. Circumgenital glands in 

 four groups ; upper laterals with 8 to 15, lower laterals with 7 to 9 orifices. A 

 few long filiform tubular spinnerets, opening on to the lateral margin ; others 

 nearer the extremity shorter and trumpet-shaped ; four or five short cylindrical 

 ducts on each side of anal aperture, opening by large but inconspicuous pores 

 on the dorsal surface, their free ends directed downwards. Genital aperture 

 between lower gland groups. Anal aperture nearer the extremity. Length o'6o 

 to o'8o mm. 



Adult male unknown. 



Eggs numerous, yellow. 



Habitat on under surface of leaves of Cyanotis pilosa. Punduloya (De- 

 cember). 



A small but inconspicuous species, but easily distinguished by the square 

 recess at extremity of pygidium.
