ASTEROLECANIUM THESPESIA, sf. nov. 
(PLATE CXXII. 1-5.) 
Test of adult female (gz. 2) subcircular: posterior extremity very slightly 
produced and broadly notched ; both dorsal and ventral surfaces moderately 
convex. Dorsum obscurely tricarinate, the carinze broadly rounded. Surface 
of dorsum weakly transversely ribbed, the irregularities usually masked by a 
scurfy or tomentose layer composed of broken and matted dorsal filaments. 
Margin with a fringe of moderately long glassy filaments which are usually very 
icregular and matted together. The imperfect condition of the fringe makes it 
difficult to determine its exact arrangement or to account for the double row of 
marginal glands found on the body of the insect. Colour greenish yellow. 
Diameter 1°50 to 1°75 mm. 
Male puparium (zg. 3) ovoid, slightly narrowed behind ; flattish ; obscurely 
tricarinate. Margin usually with indications of a fringe, but often quite naked. 
Length 1 mm. Breadth 0°75 mm. 
Adult female insect subcircular or broadly oval. Rostrum approximately 
central. Abdominal extremity (7g. 4) with the anal lobes well developed and 
prominent, each bearing a long stout sete. Between the anal lobes are four 
prominent rounded lobules, each with a longish spine. There are two slightly 
smaller spines at the base of each anal lobe—one on each side. Chitinous lip 
of anal aperture dense and conspicuous. Anal ring with six longish stout hairs. 
Marginal series of 8-shaped glands double (jv. 5), except close to abdominal 
extremity, where it becomes single ; ventro-marginal simple pores well defined. 
Dorsum thickly strewn with 8-shaped glands of same size as those of the 
marginal series. Diameter I to 1°5 mm. 
Adult male unknown. 
On small branches of Thespesia populnea. Jaffna. March. The insects 
occupy small depressions in the bark (jig. 1). Superficially resembling 
A. variolosum and A. pustulans, but readily distinguishable by the regular 
double series of marginal glands. From A. vendvuosa, which has a double 
marginal series of paired glands, the present species may be distinguished by 
the presence of numerous similar glands on the disc of the dorsum.
