It has, unfortunately, not been possible to obtain specimens from the 
type material to prove absolutely the correctness of the association 
of these specimens with the species described by Kuwana on sugar 
cane from the Bonin Islands. 
The only exceptions to the use of the name “calceolariae” for the 
gray sugar-cane mealybug in recent literature appear to be those 
found in the references of Kotinsky (6) and Ehrhorn ( 1; 2 , p. 237 ). 
The first writer evidently confused and reversed the application of 
specific names to the two species boninsis and sacchari (Cockerell). 
The second author, on the basis of a comparison of specimens by 
E. E. Greea, assigns the species calceolariae on sugar cane of authors 
to the species saccharifolii of Green. If one is to accept Green’s 
original description as accurate, there is no possibility that the form 
here designated as boninsis can be identical with saccharifolii , since 
Green (5, p. 23-24) states very definitely that there is a group of 
about 8 stout pointed spines on each lobe of the apical abdominal 
segment and that the other segments, including both abdominal and 
thoracic, bear from 4 to 6 similar spines on processes on each margin. 
This description of the cerarian spines and that given of the dis¬ 
tribution oi the multilocular disk pores is so precise and so very 
different from the condition in boninsis (calceolariae on sugar cane of 
authors) that there would seem to be no possibility whatever of 
confusing the two species. Should the description prove to be seri¬ 
ously erroneous, ana the type specimens actually identical with the 
species here designated as boninsis , Green’s name will, from the dates 
of publication of the species, take precedence, since boninsis was 
described by Kuwana (7, p . 161-162) in 1909, more than one year 
later than the publication date of Green’s species. 
The latest contribution to this subject is that made from Hawaii 
by Fullaway (3, p. 312-314), where the name Trionymus calceolariae 
is used for the species under discussion. None of the specimens 
examined shows clearly the heavy ventral, chitinized anal lobe thick¬ 
ening emphasized by Fullaway in his drawing, although in many 
specimens the structure is vaguely suggested. 
Pseudococcus calceolariae maskell (fig. 4) 
Adult female. —(Described from slide mounts only. Nothing available 
regarding external appearance, color, or secretion. See Maskell description 
for this.) Length as mounted averaging about 3 mm., width a little more than 
1.5 mm., derm clearing completely except for appendages, and a tendency 
towards a thickening underlying each anal cerarius; antennae normally 8-seg- 
mented; measurements in microns about as follows: I, about 64; II, 40 to 78, 
average about 65; III, 57 to 93, average about 72; IV, 33 to 57, average about 46; 
V, 36 to 64, average about 48; VI, 36 to 43, average about 40; VII, 43 to 50, aver¬ 
age about 47; VIII, 93 to 117, average about 107; legs not unusual, hind pair, so 
far as can be determined, without pores, except possibly a few large faint ones, 
femur slightly longer than tibia, claw stout, somewhat curved, without denticle, 
claw digitules rather stout, swollen at apices, exceeding claw, tarsal digitule 
slender, only slightly knobbed, likewise very slightly exceeding claw; beak 
elongate conical, appearing distinctly 2-segmented; with 17 pairs of cerarii made 
up of spines, triangular pores, and accessory setae, all, except the two or three 
anterior pairs, with 2 spines in each, these with 3, the spines of the posterior 
cerarii much larger than the others, intermediate cerarii with, on the average, 
about 10 pores and 2 accessory setae, but these numbers varying, each posterior 
cerarius with as many as 10 large accessory setae and around 50 triangular pores, 
these scattered, each posterior cerarius underlaid by a chitinous thickening, 
fairly distinct in stained mounts; apical seta about 200 m long, without any 
definite ventral thickening accompanying it; anal ring typical for the genus,
