deux sexes de digitules a extremite renflee ; huit poils sur I'anneau genito-anal ; deux 
poils sur le balancier ; antennes de neuf articles dans la femelle, de dix excessivement 
longs dans le male." 
The ? characters may be suramarized thus : — Eyes prominent, digi- 
tules not clubbed, anal ring with eight hairs, antennae with 9 segments. 
The ^ characters are remarkable ; the size especially (3 mm. long 
without wings) compared with that of the 5 (3'5 mm.) makes one doubtful 
w^hether the insect described is the male of that species or not. 
39. PUTO (?) AFKICANUS sp. n. 
(Plate XXI., Figs. 41-41/.) 
Adult $ enclosed in a dense felted or papery sac, which is generally 
white or yellowish in colour. Many of the sacs, in the dry material at 
hand, are broken at one end, and appear as white cups attached to 
the stem of the host-plant. 
The ovisacs, when not deformed by massing together, are regularly 
elongate oval about 2 mm. long and 1-2 mm. in diameter. The large 
number of small slender sacs beneath the larger ones suggests that either 
the younger $ form inhabits a sac, or that large numbers of males are 
produced. 
Ova or larvae not observed. 
^ : Not known. 
Adult 2 : The adult 2 as recovered from dry material is merely a black 
shrivelled mass without indications of secretionary covering of any kind, 
and without lateral or caudal filaments. 
In boiling NaOH the insect is restored to the usual elongate oval form 
of Pseudococcus and is at first deep black in colour. Later it simulates the 
insects ot the filamentosus group of mealy-bugs, being very difficult to clear 
and taking on a deep green colour before clearing. When stained and 
mounted the insect differs from Pseudococcus in having antennae of a 
different type although they are 8- or 9-jointed (Plate XXI., Figs. 41-41a) ; 
in having the anal ring with 8 hairs instead of 6; and in having conical 
spines scattered over the posterior part of the body. From Eriococcus 
it differs also in the antennae ; in having the spines comparatively short 
and of an indefinite arrangement ; and particularly in the absence of 
the elongate caudal lobes. 
In mounted specimens the body averages 1-7 mm. in length and 0*9 mm. 
in breadth. The antennae are 8- or 9-jointed, the apical segments being 
wider and more irregular in outhne than is usual in Pseudococcus spp. 
(Plate XXI., Fig 41).
