with from five to ten. The spines on the first five segments are 

 more slender and sharply pointed (pi. ii, fig. 15), those on the remain- 

 ing segments being blunt and papilliform — like the dorsal spines 

 (pi. ii , fig. 16). There are fine hairs and small circular ceriferous pores 

 on the median and submarginal areas. Each hair springs from a 

 conical pit (pi. ii^fig. 15). In my earlier description (vol. vii, part i), 

 drawn up from an imperfect mount of an immature example, the 

 median series of spines were erroneously stated to be dorsal. 



There is no trace of buccal apparatus, or of eyes. 



Antenna (pi, ii, fig. 10) 7-jointed ; the basal joint broadest, the 

 apical joint narrowest and ovoid : all the joints (except the first) 

 with an apical series of stout spiniform hairs. 



Anterior limb (pi. ii, fig. n) large and stout ; femur with some 

 longish stout hairs on the side and inner margin ; tibia approxi- 

 mately quadrate ; tarsus and claw in one piece, stout, strongly 

 falcate, grooved — near the tip — on the inner edge, several stout 

 hairs near the base, probably representing the ungual digit ules. 

 Second and third limbs smaller but well developed (pi. ii, fig. 12) ; 

 tibia elongate; tarsus distinct; claw slender, falcate, swollen at 

 base. 



The four thoracic spiracles open on the ventral surface, be- 

 hind the bases of the first and second limbs respectively. They, 

 are large and con.spicuous. The opening of each spiracle (pi. ii, fig. 

 13) is circular consisting of a broad flat chitinous ring, with strongly 

 defined outer margin; within the central cavity is the opening 

 into the trachea and four circular ceriferous pores. Four minute 

 pores are present, close to the outer border of the chitinous ring. 

 The seven pairs of abdominal spiracles, one of which opens on the 

 venter and the remainder on the dorsum, are much smaller. The 

 external aperture is subquadrate (pi. ii, fig. 14) and leads into a 

 thickened chitinous chamber which is connected with paired tracheal 

 vessels. In the mouth of the external opening are four circular 

 ceriferous pores. 



Both the anal and the genital apertures open on the venter. 

 The former is small and surrounded by a rather dense chitinous 

 ring. The genital orifice is transversely elongate, and appears to 

 be situated at the junction of the terminal with the penultimate 

 segment. 



Dimensions variable, some individuals being more than double 

 the size of others. A corresponding variation is found in the 

 dimension of the limbs. The smallest adult females that I have 

 seen measure 1*5 mm. by 115 mm., and the largest 4 mm. bv 

 3 mm. 



Female nymph pale yellow, sometimes orange yellow or 

 reddish ; subglobular ; without limbs or external appendages of 

 any kind. Derm minutel}^ pustular or cellular {vide vol. vii, 

 part i. No. 5, p. 74, text figure i). Internal rostral apparatus 

 (consisting of tentorium and setae) strongly developed in some in- 

 dividuals, but weak in others ; the condition probably dependent 

 upon the stage of development of the nymph. On each side of the
