those on dorsum, at least, usually 
accompanied by one or two tiny clear 
circles; body spines of the usual sort, 
and arranged in the usual 10 dorsal 
and 11 marginal clusters, approxi¬ 
mately as shown in figure; dorsal 
spines longest, straight or slightly 
curved, ventral abdominal spines the 
shortest and stoutest; body with setae 
occasionally both dorsally and ven- 
trally, these longer and larger dorsally; 
ovisac band rather narrow, made up as 
usual of crowded spines, a single row 
of scattered disk pores about 3 to 4 
deep along and within the 
inner margin, band inclosing 4 
transverse rows of scattered 
spines; anal ring not unusual 
for the genus, the inner mar¬ 
gin of the pore bands indis¬ 
tinctly angulate anteriorly but 
without such angulation be¬ 
hind, ring bearing the usual 
6 setae; posterior portion of 
the ventral abdominal area 
with some small clear disks, 
possibly ventral cicatrices, in 
addition to a number of the 
usual disk pores. 
This species has been re¬ 
described from two specimens 
on “ Scalesia microcephala 254, 
Tagus Cape Albemarle I. Type 
L. 375-S. 1 Entomological Lab. 
Stanford University S. I. K. 
1901” remounted and very 
kindly loaned for study by 
Prof. G. F. Ferris of Stanford 
University. Additional speci¬ 
mens, recently reported on by 
the writer, collected by Dr. 
Wm. Beebe on Heliotropinum 
parviflorum (Borraginaceae) 
and on Bursara graveolens 
(Burseraceae) in the Galapagos 
Islands, have also been exam¬ 
ined.

Adult female. —No specimens avail¬ 
able for redescription of external 
appearance and the following quoted 
from the original description: “Length 
about 2J^ mm., with ovisac about 7 
mm. Body pale pea green; ovisac 
strongly curved upwards, composed of 
ribbon-like longitudinal bands, which 
are contiguous, but little or not co¬ 
herent; lateral dorsal area only clothed 
with thin meal; middle of back with a 
double crest of long erect white 
lamellae; sides with long thick curling 
white lamellae, the two at the begin¬ 
ning of the ovisac on each side very 
long and curving downward over the 
side of the ovisac; caudal lamellae 
very short.” Length of body as 
mounted 2.5 mm., width about 2 mm.; 
broadly rounded posteriorly, tapering 
somewhat anteriorly; derm membran¬ 
ous, except for a fairly distinct dorsal 
median, longitudinal, somewhat chit- 
inized band extending in from the 
anterior margin about the width of the 
anterior spine cluster; antennae nor¬ 
mally 8-segmented, lengths of segments 
of one in microns as follows: I, 140; 
II, 125; III, 186; IV, 168; V, 143; 
VI, 104; VII, 96;. VIII, 207; spine, 25; 
basal portion of eyestalk flat conical, 
with an angular, protruding, hemis¬ 
pherical, apical cap; legs not unusual 
for the genus, the spines on all the 
segments relatively more elongate and 
slender than in most of the species of 
the genus, tarsal claw with 2 or 3 fairly 
distinct denticles on the inner face; 
beak stout conical, 1-segmented, with¬ 
out indication of any subdivisions; 
thoracic spiracles characteristic for the 
genus, each surrounded by a spine 
cluster, but without a distinctly de¬ 
veloped spine collar; with 7 pairs of 
long tubular, abdominal spiracles; 
derm pores of the usual quadrilocular 
disk type only, these present both dor¬ 
sally and ventrally, but much more
