the short segments of the antennae or two of them together. Stigmatic clefts 

 (fig. 17, b) relatively shallow, but very clearly defined ; spines short, obconical, those 

 at the extreme margin very minute and stud-like. Marginal spines or hairs not trace- 

 able. Antennae (fig. 17, a) of six segments, the 3rd longer than the last three 

 together. Legs normal. Length of denuded female, inclusive of the caudal 

 process, 4 - 5-4*6 mm. ; length of caudal process, 1*3— 1*5 mm. 



Male puparium (fig. 17, e, e x ). Consisting of two distinct parts; the lower half 

 boat-shaped, and of a glassy, vesicular texture, as in those typical of the genus 

 Lecanium ; the upper portion opaque, low, convex, and of a dirty beeswax colour, 

 with nine narrowly rectangular, submarginal patches of snow-white secretion. Anal

cleft apparently obsolete. On the emergence of the male the whole of the upper 

 portion falls away, leaving the ventral half attached to the food-plant. The line of 

 cleavage between the upper and lower portion is clearly defined in those puparia 

 from which the imprisoned male has not escaped. Length, 1 "6 mm.

Ceroplastes ceriferus (Anderson) Newstead, Bull. Ent. Res. i, pp. 66, 195 (1910). 



Female test. White, creamy white or dirty white ; exceedingly soft and containing 

 an excess of moisture. Form irregular, with large but ill-defined gibbose protru- 

 berances ; sides usually with two narrow opaque lines of secretion from the stigmatic 

 clefts. No trace of lateral plates. Length, 5-8 mm. 



Female, adult. More or less hemispherical, with the sides often slightly compressed ; 

 caudal process long ; integument castaneous and highly chitinised, smooth and
