colourless; anal extremity of second pellicle of a more decided 
yellow than the rest. Long. *75-1°25 mm. 
Q Adult elongate ovate. Rostral filaments short. Pygidium 
(fig. 8) rather widely rounded and continuous with margin. 
Ventral compound spinnerets in five groups ; anterior group with 
3-4, anterior laterals 9-13, posterior laterals 8-17 ; median lobes 
short, very widely separated, and between them six very short 
spines, three on each side of the median line ; immediately beyond 
the lobes are two more spines, which are followed by faint traces 
of the second and third !obes and one or two plates. Often, how- 
ever, spines, plates and lobes are entirely absent. Long. 1°25 mm. 
¢ Scale white, closely felted, tricarinate ; pellicle pale ochreous, 
or greenish yellow, cephalic extremity darker. 
dg Adult unknown. 
Hab. On Cypress. ‘‘ Constantine, on the side of the 
Mansourah, on young trees planted by the garde 
forestier’s house, and elsewhere in the wood. It occurs 
also more sparingly in the Mohammedan cemetery... . 
where in fact it was first noticed.” 
The study of this unique species has given me infinite 
pleasure. ‘I'he interesting satiny-white striate scales may 
be recognized at a glance; and the widely separated 
median lobes are very characteristic. 
It is strange, though, that many of the 2 should be 
without marginal appendages to the pygidium, and even 
when these are present they are more or less rudimentary. 
Parlatoria afinis, sp.u. (Plate 1V., figs. 9-12.) 
Seale of the ? circular, when isolated and upon the smooth 
surface of the leaf or fruit, but when over-crowded it becomes 
elongate or widely pyriform ; dusky white or pale ochreous ; larval 
pellicle at the margin in front, rarely extending beyond it ; second 
pellicle occupying nearly one-third of the scale ; both pellicles 
variable in colour, usually dark obscure green or piceous, rarely 
ochreous red; the anal extremity of the second pellicle often dull 
orange. The scale is unusually thick, and dusted with ochreous or 
greyish meal. Diam. 1-1°25 mm. 
Q Adult (fig. 9) almost circular. Rudimentary antenne with a 
short curved spine (fig. 10). Rostral filaments extending to middle 
of body. Segmentation distinct. Margins of abdominal segments 
fringed with serrate and simple plates, Dermis at margins of
