Eriococcincc. 351 



ERIOCOCCUS TRANSVERSUS, nuv. 

 (Plate CXXXVI.) 



Female ovisac {Jigs. 2, 3, 4) ochreous white ; strongly laterally com- 

 pressed, and curved into the shape of a horse-shoe, with transverse ridges 

 corresponding to the segments of the body of the insect, those on the thoracic 

 area produced into strong conical prominences. Transverse diameter across 

 the dorsum, r2 5 mm. ; across the side of the ovisac, 2*50 mm. 



Adult female [fig. 5) olivaceous brown, darker beneath, curved into a loop, 

 so that the anterior and posterior extremities become approximated. There 

 is a well-JTiarked fold following the curve of the body. Dorsum {fig. 6) 

 closely set with small sharply pointed spines which are arranged in more 

 or less definite transverse bands, the bands being narrower and more con- 

 spicuous on the abdominal area : the spines rather larger on the marginal 

 area {fig. 7). Antenna {fig. 9) seven-jointed ; the second, third, and seventh (and 

 occasionally the fourth) approximately equal. Limbs well developed, tarsus 

 markedly longer than tibia {fig. 8) ; claw with a minute (scarcely perceptible) 

 denticle on inner margin near the apex. Anal ring with eight stout seta?. 

 Anal lobes cylindrical at base, obliquely conical at apex, with the usual spines 

 and terminal seta;. Length (under compression) averaging 2"o mm. 



Young larva {fig. 10) with marginal, dorso-lateral, and median series of 

 strong spines : the marginal series consisting of forty-four, the dorso-laterals 

 with seven spines on each side, and the median series with twelve pairs. 



The insects are disposed traversely across the axils of the leaves of 

 Arunduiaria sp. Q debilis) ; Maskeliya district, at an altitude of 6500 feet; 

 August, 1902. 



Allied to bainbuscE^ but differing markedly in the form of the ovisac 

 (compare plate CXXXVL fig. 4, and plate CXXXV. fig. 2). Superficially 

 resembling, in form and habit, the Japanese species omikii. 



The habit of lying transversely across the axils of leaves or the angles of 

 branches is common to the following species : af^r/j' (Sign.), tripartitus (Full.), 

 elegans (Full.), onukii (Kuw.), bavibuscc (Green), and transversus (Green). 



ERIOCOCCUS TENUIS, nov. 



(Plate CXXXVI I.) 



Ovisac of adult female pure white, elongate oval, moderately convex, 

 closely felted. Freshly constructed examples show traces of transverse 

 segmentation. Length 2*50 to 3 mm. Breadth i to I'So mm. Puparium of 

 male similar but much smaller. Length about vi^ mm. Adult female, before 

 gestation {figs. 2, 3), elongate and narrow, tapering behind, of a very pale 

 greenish yellow colour. Older females proportionately broader. Spines of
