PACIFIC SCIENCE, Vol. XV, January 1961 
Third instar (Fig. 8 a): Length 0.75 mm., 
width 0.56 mm. Elliptical. Colourless. Without 
tuberculate pattern but with scattered irregular 
small tubercles. Caudal setae situated on margin, 
strong. Tracheal pores with few teeth on margin, 
no clefts. Tracheal folds present, dotted. Mar- 
gin as in pupal case. 
PUPAL CASE (Fig. 8 b-d): Length 1.44 mm., 
width 1.15 mm. Colourless except for a circular 
pigmented middorsal area on meso- and meta- 
thorax and anterior half of first abdominal seg- 
ment, and another more elongate area on 7 th 
and 8th abdominal segments including the ori- 
fice and extending caudad of it. Shape elliptical, 
flat, widest at mid-length. Margin slightly cren- 
ulated nearly entire with numerous marginal 
ridges and grooves extending a short distance 
mesally, anterior and posterior marginal setae 
present. Submargin not defined from dorsum. 
Body of adult outlined by a row of tubercles, 
single on cephalothorax but tending to be double 
on abdomen and ending caudad of orifice. Be- 
tween this and the margin on the abdomen is 
a second row of slightly smaller tubercles in 
single series. Thoracic tracheal folds present, 
marked by dots, extending from pore to line 
of tubercles where they are dilated. Pore (Fig. 
8c) simple, without teeth, distant 0.05 mm. 
from margin, cleft present. Abdomen with scat- 
tered small circular pores especially between 
margin and outer row of tubercles. Setae not 
evident on segment 1. Posterior half of 6th 
abdominal segment between paramedian pores 
is finely spinulose. Eighth abdominal setae 0.03 
mm. long level with anterior margin of orifice, 
distant from orifice. Caudal setae 0.01 mm. long, 
one on each side of tracheal pore at mid-length. 
Vasiform orifice (Fig. 8 d) subcordate, not 
toothed internally on lateral or posterior mar- 
gins, 0.04 mm. long, 0.04 mm. wide. Operculum 
filling orifice, 0.03 mm. long, 0.03 mm. wide. 
Lingula not exposed, parallel sided, apex 
rounded, as long as operculum. Abdominal tra- 
cheal fold present, marked by dots. Pore sim- 
ple, distant from margin by closed cleft. 
holotype: Pupal case on slide mount. De- 
posited in Institut Fran^ais d’Oceanie, Noumea, 
New Caledonia. 
PARATYPES: In author’s collection. 
TYPE LOCALITY: New Caledonia, Plum, coll. 
L.J.D. 
FOOD PLANT: Psychotria deplanchei. 
This species would run to the subgenus 
Gigaleyrodes in Quaintance & Baker’s key al- 
though the tracheal pore differs. A similar tuber- 
culation of the dorsal disc occurs in Dialeurodes 
( Dialeuronomada ) dissimilis Q. & B. in which 
however the orifice is toothed. 
GENUS Dothioia nov. 
PUPAL CASE: Apparent margin not toothed, 
margin reflexed with small conical teeth. Tho- 
racic and abdominal tracheal folds not evident. 
Thoracic tracheal pore represented by two pro- 
jecting processes. Margin in the position of the 
abdominal tracheal pore with four or five ill- 
defined teeth. Apparent body margin sinuate, i.e., 
concave between the submarginal setae of which 
there are five on each side of the cephalothorax 
and four on the abdomen in addition to the 
caudal setae. 
TYPE SPECIES: D. hidentatus sp. n. 
Dothioia hidentatus sp. n. 
Fig. 9 a-h 
larva. Third instar (Figs. 9 a, h): Length 
0.45 mm., width 0.31 mm. Shape elliptical. 
Colour pale. Margin toothed. Submargin with 
10 fine short setae on each side. Cephalic area 
with one pair of fine setae and four pairs of 
spines. One pair of posterolateral thoracic spines. 
Abdomen, one pair of paramedian processes on 
first segment, seven pairs of spines laterad, 
eighth abdominal setae hairlike, level with ori- 
fice, caudal setae long. 
pupal CASE (Fig. 9c— f ) : Length 0.75 mm., 
width 0.56 mm. Colour black. Wax pattern of 
narrow linear raised elements; a median line 
along suture on anterior half of cephalothorax, 
a short transverse line on first abdominal seg- 
ment, and a longer oblique line in posterolateral 
angle of thorax. Apparent margin not toothed,
