SUPPLEMENTARY NOTES ON THE COCCIDZA OF CEYLON. 255 
times subcentral, sometimes close to the margin, concealed beneath the 
tomentose covering, visible only on the inner surface of the scale. Form 
approximately circular ; flat ; very thin and delicate in texture. Ventral 
scale remaining attached to the leaf. 
Diameter about 3°50 mm. 
Male puparium of normal form, elongate, narrow, sides almost parallel, 
strongly tricarinate : snowy-white, the pale yellow pellicle situate at the 
anterior extremity. Ventral scale well developed, completely closing the 
puparium below. 
Length 1:15 mm. 
Adult female (fig. 25) bright yellow ; elongate, narrow ; EA aioe and 
meso-thorax slightly broader than the remaining parts, Segments well 
defined, the second abdominal moderately produced at the sides, the third 
abdominal merged in the pygidium, Antenne at some little distance within 
the margin, each consisting of a small tubercle and a long curved hair. 
Mouth parts large and conspicuous, close to the anterior extremity. Spira- 
cles small ; both pairs accompanied by parastigmatic glands ; the anterior 
pair one on each side of and close to the mentum ; the second pair just with- 
in the anterior border of the meta-thorax. There is a pair (sometimes two 
pairs) of conspicuous depressed spots on the dorsal surface of each segment, 
besides a number of scar-like spots above the cephalic segment. There isa 
group of about 7 spiniform squames on the margins of the second abdominal 
segment, The pygidium, which in this section of the genus includes the 3rd 
abdominal segment, may otherwise be subdivided as in typical Chionaspis 
(vide ‘Coccide of Ceylon, Part II, p. 106, Pl. XXXI), Median. lobes large 
and diverging, partly sunk in a conspicuous median cleft (fig, 26), their free 
edges minutely serrate, their bases united, Second lobe duplex ; the mesal 
lobule prominent, elongate and narrow ; the lateral lobule, short and sloping 
away to the margin ; rather difficult to define, being more or less confused 
with the adjacent spine and squame; both lobules entire, Third lobe duplex ; 
the mesal lobule rather prominent, slightly dilated at extremity, the inner 
edge longest, the free edge serrate ; lateral lobule short, outer edge sloping 
to the margin, Single spiniform squames on the 1st, 2nd, 3rd and 4th lateral 
spaces : three or four on the 5th space : and from seven to ten on the base 
(the 3rd abdominal segment), The marginal dorsal pore on the 2nd space is 
situated on a prominent point, There are two marginal pores on the 3rd 
space, the mesal one on a prominent rounded process that may be 
mistaken for one of the true lobes : the second pore in a cleft between 
the lobules. Marginal spines rather long, particularly that between the 
lobules on the second space. Series of conspicuous oval dorsal pores at the 
junctions of the suppressed segments. Circumgenital glands in five groups 
with numerous orifices: median 8 to 16: upper latterals 14 to 25: ieee 
laterials 11 to 26, Anal and genital apertures superimposed,
