SUPPLEMENTARY NOTES ON THE COCCID^ OF CEYLON. 345 



rudimentary eyes colourless, inconspicuous. Terminal joint of antenna 

 with one knobbed hair at apex and two at side. Foot with four 

 knobbed hairs. Wings • ample, hyaline, slightly iridescent. Genital 

 sheath very long and narrow, as long as or longer than abdomen : 

 sharply pointed. Total length 0*75 mm. 



Habitat. — On Phyllanthus myrtifolius. Peradeniya. February. 

 Female insects on steins and twigs, more or less concealed beneath the 

 outer layers of the bark. Male insects on both surfaces of the leaves. 



The pygidial characters approach those of A. tenebricosus, Comstock, 

 but differ in the form, number and arrangement of the paraphyses and 

 in the absence of pectinate squames. 



Aspidiotus (Cryptophyllaspis) occultus, var. klongatus, n. var. 



(PI. I, figs. 12,13). 



Aspidiotus occultus, Green, Gocc. Ceylon, pt. 1, p. 56. 



Cryptophyllaspis occultus, Ckll., Check List, Suppl., p. 396. 



$ Puparium consisting principally of a delicate film lining the cavity 

 of the gall, the pellicles forming an operculum at its base. 



The gall itself (fig. 12) is irregularly cylindrical, constricted towards 

 the base, the ends often studaed with irregular tubercles. Length of 

 gall about 2 mm. 



$ Puparium not observed; but probably occupying shallow 

 depressions on the surface of the leaf as in the type. 



Adult $ elongate oval, abruptly constricted towards the base of the 

 pygidium. Pygidium (fig. 13) with 6 prominent lobes. Median pair 

 large and deeply coloured : others smaller and pointed. Squames ex- 

 tending beyond the lobes : stout, deeply fimbriate and furcate. Anal 

 aperture elongate, narrow. No circumgenital glands. Length 1 mm. 

 Greatest breadth 0*50 mm. 



Adult £ not known. 



The galls are massed on the under surface of leaves of Grewia sp.; 

 the aperture opening on to the upper surface. Heneratgoda. Feb. 



Differs from type in its elongate form and greater size : in the 

 cylindrical (instead of globular) form of the gall : and in the position 

 of the galls on under (instead of upper) surface of the leaf. 



Aspidiotus (Chrysomphalus) dictyospermi, Morg. 



Ceylon examples are all of the variety pinnulifera (Mask.). 



In addition to other food-plants mentioned, it occurs on Optmtia 

 cochinellifera. (Peradeniya. February.) The puparia on this plant 

 are almost white.
