Sac of adult female elongate oval, somewhat irregular in form, consisting 

 of a complete sac of stiff leathery secretion, showing no woolly filaments : 

 with a large circular anal aperture. General colour, biscuit-hrown with a 

 yellowish tint. Length, about ^ of an inch. 



Adult female pear-shaped, showing abdominal segments; general colour, 

 reddish brown, giving off a dull red in potash. Antennae seven-jointed 

 fourth, fifth, and sixth tapering, sixth shbrtest; seventh, rounded, hairy. 

 Legs moderate, tibia shorter than tarsus, claw large, digitules long, do not 

 appear to be thickened. Anal ring with apparently eight hairs. Anal 

 tubercles large, swelling out about the middle, where a stout seta springs 

 out on the inner margin, but no corresponding one on the outer margin. 

 a single stout spine at base, on outer margin. Epidermis thick, covered 

 with circular orifices, short rods and fine transparent spines. The large 

 marginal spines extending round the body, but on the abdominal segments 

 supplemented with a middle pair, so that there is a transverse bunch of 

 three pairs of spines on each of the abdominal segments. 



This species belongs to the Eriococcus coriaceus group with leathery sacs 

 with apical orifices, but corrodes the bark like E. te2J])eri; it is, however, 

 very distinct from the latter s])ecies as defined bv Maskell. 



I have named this distinct species in honor of Hugli CVoft, Esq., manag( r 

 of Salisbury Court, to whom I am indebted for manv kindnesses.

This species comes from Western Australia, and was found upon the 

 branchlets of a she-oak {Casyarina, sp.). I have specimens from Mr. A. M. 

 Lea. The ovisac is formed of a dark chocolate-brown leathery or felted 

 secretion, clouded with black, probably caused from fumagine ; broadly 

 oval, very convex, and fitting close to the bark, apparently no anal opening. 

 Length, J; of an inch. Fuller says in his first description, " Sac very convex, 

 smooth, shining, brown, resembling a small ' snake-head " shell."' 



Adult female fitting close into the sac when- alive. Antennic with seven 

 joints — first, thick ; second, short ; third and fourth, subequal ; sixth and 

 seventh, subequal. Legs, long. Anal tubercles large, chitinous, roughened, 

 tapering; each with two spines on inner margin, and one on the outer side 

 at the apex. Dorsum with irregular oval and circular pores and many 

 spines.
