SUPPLEMENTARY NOTES ON THE COCCID4: OF CEYLON, 257 
ed by a single pore at each of the first pair of spiracles, The lateral margins 
of the metathorax are set with small blunt tubercles. Pygidium bluntly 
triangular, Median lobes moderately large, widely diverging, coarsely ser- 
rate, Two serrated chitinous prominences on each side represent the lobules 
of the first lateral lobes (fig. 32). Spines well developed; two between the 
median lobes: others in the usual positions: There isa single large, stout 
squame near the extremity on each side, Anal aperture close to base of 
pygidium. Circumgenital glands in five groups, sometimes in a continuous 
arch: median 6to7: upper laterals 12 to 16: lower laterals 20 to 24, 
Length 1 to 1°12 mm, 
Adult male not observed. 
Habitat,—On leaves of Gelonium lanceolatum : Pundaluoya: August, 
This species is remarkable for, and may easily distinguished by, the ex- 
traordinary development of the usually small interantennal tubercle. The 
organ exists in saprosme as a minute spinous tubercle, In F. thee (Green, 
MS ), from India, it appears as a prominent spatulate process, It is difficult 
fo imagine any use for the elephantine proboscis of the present species.
