The pupa case proper is flat, yellow in color with a large dark brown 
area on the thorax and also on the abdominal region. These brown 
areas vary in extent and may become coalescent, covering practically 
the entire dorsal disc. Size of case about 1.66 mm., by 1.5 mm., ovate 
in outline, widest caudad centre. Body segments quite distinct on 
dorsal disc. Margin of case, (Plate X XVI, Fig. 7), is seen under high 
magnification to be practically entire, though appearing incised under 
lower power, due to the presence just within margin of a series of 
small, fusiform glands, and from which delicate sutures extend mesad. 
On caudal segment of case is a pair of reduced compound pores, (Plate 
XXVI, Fig. 2), each giving rise to a long slender spine homolagous 
apparently to the so-called ‘central process.” A single reduced 
pore is usually present on the third abdominal segment well to one 
side of the median line, either to the right or left, more usually on the 
right side, (Plate XXVI, Fig. 3). We have seen no instance in which 
both pores were present in the same individual. The variability in 
position of this pore and the rudimentary condition of the pores on the 
anal segment indicate the intermediate status of the species between 
Dialeurodicus in which no pores are present, and Aleurodicus in which 
genus these are mostly well developed. Numerous minute pores, 
appearing as clear white dots, are scattered over the body, some of 
which occur in groups, especially on the abdomen. 
Vasiform orifice, (Plate XX VI, Fig. 13), small, transversely elliptical 
in general outline, the cephalic margin being straight. The operculum 
about half fills the orifice, is transversely elongate, the sides rounded 
and caudal margin concave. The lingula is much shortened, broadly 
rounded about one-third as long as the orifice. On ventral surface 
of case the antenne and legs are distinct, each of the latter terminating 
in a hooked spine. (Plate X XVI, Figs. 5 and 17). 
Adult 9 .—Length from head to tip of abdomen about 2.5 mm. 
Forewing ‘about 2.5 mm., long by 1.63 mm., wide, rounded, marked 
with small groups of dots as shown in the figure, (Plate XXVI, Fig. 8); 
hind wing unmarked. Hind tibia about 0.9 mm., long, hind tarsi 
together 0.5 mm., in length, the basal joint being about twice the length 
of distal; claw usual, with spine like paronychium, (Plate XXVI, Fig.15). 
The general color of body is yellow with brown coloration on legs, body 
sutures, parts of antennal joints, etc.; the tip of mentum is dark brown 
or blackish. Vertex rounded and armed with a row of stout spines. 
Frons armed with tubercles (Fig. 14). Head not showing the cone 
shaped extension of the vertex present in species of Dialewrodicus. 
Compound eyes ‘dumb bell’? shaped, dark red or brown. Ocelli 
prominent. Antenne (Plate XXVI, Fig. 18) of seven segments; 
segment I, short, cup-shaped; II, over twice as long as I, fusiform, 
dusky in color. Segment III, about 0.35 mm., in length, not quite 
as long as the four distal joints together, slender, dusky on distal fourth 
armed with about fifteen sensoria. Segments IV and V subequal in 
length as are joints VI and VII. Segments III-VII imbricated.
