CEROPLASTODES VIRESCENS, sA. nov. 
(PLATE CX.) 
Early adult female (igs. 1-3) with dorsum covered with minute waxy 
spicules and hairlike filaments ; of a dull green tint. 
Later, when the permanent test is in process of formation, there are indica- 
tions of tessellation, the hairlike filaments disappear, except at the margin, and 
the spicules become larger and more prominent. 
The available material does not include examples of the fully formed test or 
of the insect after gestation, but the latter doubtless shrinks into the anterior 
portion of the test, the hinder parts being filled with ova—as in other species of 
the genus. 
Denuded insect dull olive green ; derm coarsely mamillate. Antenne (7g. 4) 
eight-jointed ; third joint longest, but approximately equal to fourth and fifth ; 
sixth, seventh, and eighth shortest and equal ; formula: 3, (4, 5), (1, 2), (6, 7, 8). 
Stigmatic spine (/g. 5) long and slender. Marginal spines (fg. 6) crowded, 
three or four deep. Length 2°25 to 350mm. Breadth 1°75 to 2°75 mm. 
On the terminal shoots of 7ieobroma cacao. Matale. December. 
Though described from meagre and not fully matured material, the cha- 
raciers are sufficient to separate this from the other two species found in 
Ceylon. It approaches c#zfon in the form of the antenna, but differs from its 
allies in the arrangement of the marginal spines (see 7g. 7), and in the distinct 
green colour of the early test. In both cajanz and chitom, the marginal spines 
are only 2-deep.
