LECANIUM (PARALECANIUM) PARADENIYENSE, sp. nov. 



(Plate XC.) 



Adult 9 {fig. 4) deep reddish brown ; ovate, narrower in front, evenly 

 rounded at each extremity ; very slightly convex above ; with a broad median 

 cavity below the abdomen forming a shelter for the newly hatched larvre. A 

 very indistinct median longitudinal ridge, on each side of which are three 

 longitudinal series of impresssed polygonal spaces with concentric markings. 

 Marginal area with many short transverse carinEe. Surface, except in 

 polygonal spaces, minutely and closely punctate. Scales of anal operculum 

 {fig. 6) acutely pointed at apex ; outer edge almost straight ; base and 

 outer edges nearly equal in length, the intervening angle rounded. Stig- 

 matic cleft {fig. 5) with three stout blunt spines. Margin {fig. 8) supporting 

 a fringe of overlapping flabellae; the margin itself unequally crenulate, 

 the larger crenulations being above the points of attachment of the flabellee, 

 with two or three smaller points between them, each point corresponding with 

 a small dark cuneiform mark. There is a distinct marginal zone, not apparent 

 in the living insect, but very conspicuous in macerated examples. Eyes con- 

 spicuous in prepared specimens as translucent spots at a considerable distance 

 from the margin. Derm with a few scattered conspicuous translucent pores, 

 chiefly on the submarginal area ; many less conspicuous small oval and circular 

 derm-cells, largest towards the margin, where they tend to form series parallel 

 with the marginal carinse. Antenna {fig. 7) with six joints, of which the third 

 is much the longest, and equal to fifth and sixth together. Antennal formula : 

 3, 6, I (2, 4), 5, or 3, 6, I (2, 4, 5). Legs rather small, but well developed ; tibia 

 and tarsus of about equal length, the joint very inconspicuous. Anal ring with 

 six stout hairs. Length 3'5o to 4 mm. Breadth 2'5o to 3 mm. 



Adult <5 {fig. 3) reddish brown. Wings hyaline ; costal nervure purplish 

 pink. Form rather broad and depressed. No caudal setEe. Antenna with the 

 usual three knobs at apex. Length, including genital sheath, i'25 mm. 



Male puparium {fig. 2) oblong oval ; glassy ; divided into eighteen plates, of 

 which three are central and fifteen marginal. Length 2 mm. Breadth i'25. 



Young larva pale brick red ; broadly oval. 



Only living larvae and egg pellicles are seen beneath the female, which is 

 probably ovoviviparous. 



Habitat on upper surface of leaves of the cultivated pepper, Piper nigrum, 

 Peradeniya (November). 



This species is the largest of its group, with the exception of L. expansum, 

 from which it differs in the possession of well-developed legs.
