MonophlebincF. 457 



marginal and marginal series of forwardly curved compact waxy processes 

 which may be either of an ochreous-yellow or orange-yellow colour, and three 

 longer horn-shaped processes on each side of the thorax. The antennas {fig. 

 ii) are still six-jointed, but the proportionate length of the joints is different 

 (compare yfi.''-^- 12 and 13). Legs {fig. 15) still comparatively slender) ; but the 

 tarsus is reduced to rather less than half the length of the tibia. The dermal 

 spines covering the area between the ceriferous tracts are longer and slightly 

 tapered to a rounded point. Pores and setae as in the adult inse-.t, but less 

 numerous. Length of body 3"5 to 4 mm. 



I have been unable to determine, exactly, whether there is a later nymphal 

 stage, intermediate between the one just described and the adult insect. But a 

 single individual has been observed, associated with exuviae corresponding to 

 the previous stage, which appears to combine characters of both the nymphal 

 and adult stages. The antennae are eleven-jointed, but shorter than those of 

 the fully mature insect, and the divisions of the antennal joints are not so strongly 

 defined. The legs, also, while showing a great increase in size, are still not so 

 large or stout as those of the adult. The dermal spines {figs. 27, 28) conform 

 more with those of the previous nymphal stage, the spines of the intermediate 

 areas being elongate and tapered to a rounded point (compare y^i/x 20 and 28). 

 I can detect four pairs only of abdominal spiracles in this individual. Length 

 of body 7 mm. 



It is remarkable that there seems to be no graduation in the number of 

 antennal joints between the six-jointed and eleven-jointed stages. 



In the nymphal stages, during life, a long slender glassy tube projects 

 upwards from the anal aperture. 



On Li f sea, Ct?inamoi>ium, Mallotus, Loranthiis, Ewya, Psychotria, and 

 Vi/is sp. Pundaluoya ; Watawela ; Maskeliya ; Hakgala ; Namunakuli ; 

 HaldummuUa ; Randarawela ; Patipola ; Horton Plains and Nuera Eliya. 

 Occurring singly ; the earlier stages on the foliage, the more advanced stages 

 on the stems of the plants. Apparently confined to the hill districts. I have 

 never taken it at elevations much below 4000 feet.
