Eriococcincs. 353 



usually constant : (3, 4, 7), 2, (5, 6). Legs well developed ; tarsus markedly 

 longer than tibia {fig. 11); claw {fig. 3) with a distinct denticle on the inner 

 side, near the apex ; ungual digitules very delicate and inconspicuous. Anal 

 lobes prominent ; tapering to apex which is evenly rounded {figs. 6, 7), with 

 three stout spines ; caudal setae one and a half to twice the length of the lobes. 

 Anal ring {fig. 6) with 6 stout setae, and a similar seta, close to but distinct 

 from the ring, on each side of it. Length from i"25 to 2"o mm. ; averaging 

 175 mm. 



Adult male not observed. 



Young larva {fig. 2) pale yellow : eyes black. 



On under surface of leaves of Rhodomyrtus roseus. Nuera Eliya ; Maskel- 

 liya ; Badulla. At altitudes of over 6000 feet. 



A single example, found on Rhodomyrtus on the isolated Namunakuli hill 

 (Uva District), departs frrom the type in having longer and proportionately 

 more slender antennas and limbs {figs. 10, 12). The tarsus, in this form, is 

 approximately equal to the tibia. In other characters this example is inseparable 

 from the type. 



ERIOCOCCUS OSBECKI^, nov. 

 (Plate CXXXIX.) 



Ovisac of female creamy white ; oblong oval, length approximately twice 

 the breadth ; moderately convex. Length averaging 2 mm. 



Puparium of male much smaller. Length i mm. 



Adult female similar in form and general characters to E. rhodomyrti^ but 

 differing in the absence or reduction of the smaller interstitial spines found on 

 that species. Consequently the longitudinal series of large spines are very 

 clearly defined {fig. i). The marginal series of spines is more regular and less 

 crowded. Antenna {fig. 3) seven-jointed, third longest or equal to seventh, fifth 

 and sixth always shortest and subequal. Legs with tarsus markedly longer 

 than tibia {fig. 4) ; the claw {fig. 5) strongly falcate and with a small denticle 

 near the apex. Anal lobes {fig. 2), slightly larger than those of rhodomyrti 

 Anal ring with six stout setas. A similar seta at the base of each lobe often 

 impinges upon the anal ring. Length i"5o to 175 mm. Average of thirteen 

 examples 1-55. Breadth 075 to ro, average ego mm. 



On leaves of Osbeckia sp. Namunakuli (over 6000 feet), Badulla. February. 



The habit, appearance and general characters of this insect closely resemble 

 those of E. rhodomyrti, which also occurs in the same locality. There is, how- 

 ever, a constant difference observable in the character of the dorsal spines, as 

 described above. Osbeckice is rather a smaller insect.
