large "disc" glands, most common in the abdominal region, where they 
are arranged in close order across the segments. 
The antennae are 9-jointed, the range of measurements being :— 
(1) 36-48 ; (2) 72-75 ; (3) 40-48 ; (4) 27-40 ; (5) 47-52 ; (6) 44-52 ; 
(7) 44-52 ; (8) 40-45 ; (9) 68-78. 
The mentum is normal, about 110 f.i long. The eyes are comparatively 
large and conspicuous. 
The legs approximate : —

The tarsal digitules are slender hairs. Digitules of the claw slightly 
knobbed. 
The setae of the anal lobes are about 140 ^ long. In addition to the 
long setae each lobe bears a few shorter hairs and 4 or 5 stout conical 
spines. The setae of the anal ring are about as long as the long setae of 
the lobes (140

Gen. PSEUDOCOCCUS Westw. 
This genus comprises the well-known insects commonly known as 
mealy-bugs." Their soft bodies are usually covered with a more or less 
dense coat of powdery secretion. 
The shape of the body is generally elongate oval, and there are usually 
two short, rounded, caudal lobes which bear the caudal setae. 
The antennae are 6- to 9-jointed, but 8 is the most common number. 
As a rule the oviparous species construct a dense ovisac of white 
cottony material, whereas those which are viviparous make no such 
ovisac. 
N.B. — The synonymy of this genus, as used in this paper, requires explanation, or 
rather justification, as it comprises forms generally included in the genus Phenacoccui^ 
CklL, and encroaches upon the genus Ripersia Sign. 
Pending further study, the results of which it is hoped to publish at a later date, 
a brief explanation will suffice. 
I am quite convinced that the forms included by Mrs. Fernald (Catalogue, 1903) 
under the genera : — Phenacoccns (p. 89) ; Ceroputo (p. 94) ; Tylococcus (p. 95) ; 
Trionymus (p. 96) ; Pseudococcus (p. 96) ; Erium (p. 112) ; Pseudoriperda (p. 115) ; 
Ripersiella (p. 115) ; and Ripersia (p. 116) are closely related. In fact they probably 
represent a phylogenetic series originating in a form similar to Ripersia s. str. All
