SUPPLEMENTARY NOTES ON THE COCC{D4 OF CEYLON, 73 
Genus AONIDIA. 
AONIDIA BULLATA, Green. 
In my original description of the female puparium, I suggested that the 
first (or larval) pellicle is probably dislodged during the globular development, 
of the anterior part of the scale. Examination of further material shows 
that this actually takes place. The early female scale is very similar to the 
male puparium : but the white secretionary area is more extended behind. 
After the moult, the globular expansion of the anterior parts of the insect 
raises the larval scale and finally dislodges it completely. 
Adult male pale lilac, head darker: meso and meta-notal plates and legs 
pale fulvous :apodema reddish-brown. Form broad and depressed: gene 
widely expanded : genital sheath nearly half length of body, Antenne 10- 
jointed : half length of body : 10th joint with one terminal and one lateral 
knobbed hair, 
Foot with 4 digitules. 
The food-plant of the species proves tobe Nothopegia Colebrookiana, 
Since the publication of the first part of the “‘Coccide of Ceylon” five 
more species belonging to this section have been discovered: all of them new 
to science. 
AONIDIA SPATULATA, n,sp. (PI. C, Figs. 10, 11,12, 13.) 
Female puparium (fig. 10) hemispherical, consisting chiefly of the enlarged 
second pellicle, which completely encloses the adult insect. Median area 
exposed, castaneous-brown or blackish-brown, highly polished: marginal 
area broadly covered with pale reddish-yellow secretion. First pellicle 
usually missing in fully developed examples : in the earlier stages (fig, 11) it 
can often be found still partially attached. Diameter 0°75 mm. 
Male scale (fig. 12) circular: flattish : pellicle central, Colour reddish- 
yellow, pellicle pale clear yellow. Diameter equal to that of female, 0°75 mm, 
Adult female much smaller than in previous stage, completely concealed 
within the second pellicle. Outline almost circular. Anterior parts rather 
dense, Mouth large and conspicuous, 
Extremity of pygidium (fig. 13) truncate, as in bullata. Lobes eight : the 
median pair represented by narrow chitinous bands on the margin; 2nd, 
3rd and 4th pairs bluntly conical, Between the lobes are some remarkable 
spatulate processes, dilated at the extremity : 2 betwe n the median lobes, 2 
lateral of the median, and 3 lateral of each of the other lobes, the outermost 
ones usually bi-capitate. No circumgenital glands, | ength 0°50 mm. 
Adult male not observed, 
Habitat—On.upper surface of leaves of Psychotria thwait-sii ; Pundaluoya, 
A very small and inconspicuous species, but quite unique in the remarkable 
marginal characters of the pygidium. 
Mr. Newstead has suggested the name Gymnuspis for a new genus to con- 
tain his G. echmew and my Aonidia bullatu: founding the separation from
