limbs small, short and stout (pi. iii, fig. 26). Coxa comparatively- 

 large. Tarsus small, fused with tibia but distinct from claw which is 

 sunk into the apex of the tarsus like the fang of a tooth. The 

 claw itself (pi. iii, fig. 27) is long and slender, strongly falcate. There 

 appears to be a tubular channel from the tip of the claw to its 

 base, communicating with an oval cyst which occupies the greater 

 part of the tarsus. The whole limb clothed with very long 

 slender hairs. 



There are four large thoracic spiracles, and eight pairs of 

 small abdominal spiracles The thoracic spiracles are placed on 

 the venter, in the interspaces between the legs. The external 

 aperture of each is horseshoe-shaped (pi. iii, fig. 28). with a densely 

 chitinous rim, opening into a chamber the sides and floor of which 

 are studded with circular ceriferous pores. A densely chitinous 

 paraphysis, with a broadh^ expanded extremity, runs inwards 

 from the external stigmata. The abdominal spiracles, though 

 properly belonging to the dorsum, have assumed a ventral aspect 

 owing to the expansion of the dorsal area which overlaps the 

 comparatively narrow venter. The anterior spiracle on each side is 

 shifted outwards until it assumes an almost directly lateral aspect. 

 The external aperture of an abdominal spiracle (pi. iii, fig. 29) 

 has a dense chitinous rim, with a tooth-like projection on its upper 

 and lower edges. There is an irregular ring of ceriferous pores 

 just within the o^^ening. 



The anus (pi. iii, fig. 30) is represented by a lunate chitinous 

 bar, within the thickness of which there is a very narrow linear 

 opening. 



The derm — both of the dorsum and venter — is studded with 

 small circular multilocular ceriferous pores (pi. iii, fig. 31). 



Size very variable. The smallest example in my series 

 measures 375 by 3'25 mm., while the largest is 11 by 8 mm. 



The nymphs apparently undergo several stages, but I have 

 been unable to determine their exact number. The final stage 

 (which discloses the adult insect) is in the form of a globular or 

 subglol)ular c3-st, of an opaque black colour and dense texture. 

 The cysts are apparently naked, consisting of the hardened cuticle 

 of the nymph, with fragmentar}^ and inconspicuous patches of 

 very thin nacre. They vary greatly in size, those from the 

 Bellary district (pi. iii, fig. 32), with a diameter of 7 to 8 mm., 

 averaging four times the size of those received from the vShimoga 

 district (pi. iii, fig. 33) which range from 3*5 to 5 mm. in diameter. 

 Some of the latter are more irregular in shape, showing a 

 prominence on one side, which probably represents the original 

 point of attachment. 



In my earlier observations (loc. cit.) upon this species, it was 

 noted that " after boiling in caustic potash, the black derm 

 becomes partially decolorized and separates into two layers. The 

 outer layer swells and becomes rugulose, but still retains its 

 pustular structure. The inner layer is minutely granular." The 

 later examples, under .similar treatment, did not exhibit this
