PACIFIC SCIENCE, Vol. IV, October, 1950 
The pronotum has the three separated longi- 
tudinal dorsal stripes which are weakest an- 
teriorly. The continuation of these over the 
remainder of the thoracic dorsum is indicated 
by faint infuscation on the mesopraescutum 
and mesoscutum, while the mesoscutellum 
has a median, elongate oval blackish spot. 
All the legs are yellow. Only traces of infus- 
cations are found on the propodeum and at 
the extreme base of the abdomen. 
The darkest female has the color as de- 
scribed for the typical female but the scape 
and pedicel are dark brown to black. As with 
dark males, on some the black extends down 
onto the front from the line between the 
lateral ocellus and the compound eye. The 
lateral spot of the three on the head above is 
narrowly oval and on some it is extended as 
described for dark males. The median spot 
extends to unite with the black around the 
foramen magnum. The three black stripes 
on the dorsum of the thorax are very prom- 
inent and contrast with the adjacent greenish- 
yellow. The lateral stripe widens over the 
mesoscutum, becomes narrow posteriorly, and 
extends onto the axilla. The median stripe, 
which is abruptly broader at the anterior area 
of the mesopraescutum, becomes narrowed at 
the anterior margin of the mesoscutellum and 
extends considerably beyond the transverse 
line (on one specimen it extends almost the 
whole length). The coxae and femora and 
front tibia are infuscated, appearing for the 
most part dark brown or black. The pro- 
podeum is nearly entirely dark brown to 
black, and the abdomen, except for lateral 
yellow spots on terga IV-VIII as described, 
is also black. 
Females vary in size as follows: length 
10.0 (8 in curved position)-! 4.0 mm.; abdo- 
men 4.4-6.6 mm.; ovipositor 24.0-33.0 mm. 
COMMENTS: Specimens of this very vari- 
able species were all reared from seeds taken 
from the same Pandanus tree, which grew on 
the shore. The species is unusual in that it 
represents the largest species of Megastigmini 
yet described. It probably occurs over most 
of the southwest Pacific. Females may be dis- 
tinguished from those of the following new 
species by the more robust form, longer ovi- 
positor, difference in appearance of the stig- 
ma, and several other characters. 
Pulvilligera neo-caledonica n. sp. 
Female: Length 9.5 mm.; abdomen 4.0 
mm. Ovipositor 16.5 mm. Outline of head 
from above nearly circular but wider than 
long; vertex medially nearly flat, sublaterally 
somewhat depressed and with few shallow 
setigerous punctures; occipital carina sharp 
but not strongly developed, evenly arched 
except medially above; posterior ocellar line 
about equal to ocellocular line and both 
about two- thirds as long as ocelloccipital line; 
antennal scrobe only moderately deep and 
not compressed, not markedly bent, and equal 
to combined lengths of pedicel, ring segment, 
FI, and about one-fourth FII; pedicel oval, 
only a little wider than funicular segments, 
which become slightly shorter progressively 
from FI-FVII inclusive, and are nearly cylin- 
drical and at least 2.5 to 3 times longer than 
thick; sculpture below and laterad of anten- 
nal bases strongest, consisting of irregular ar- 
cuate rugulae directed more or less obliquely 
from the margin of the clypeus; dorsal area 
of front adjacent to eye extensively reticulate, 
and less so below anterior to fronto-genal 
suture; vertex and temples weakly sculp- 
tured at most. Pronotum a little longer than 
wide, broadly arcuate anteriorly and with 
only a shallow median emargination, tra- 
versed above by regular rugulae only moder- 
ately strong; remainder of thoracic dorsum 
similarly sculptured except that the axilla and 
mesoscutellum are less noticeably rugulose 
to nearly smooth, especially nearly the entire 
surface of the latter, which shows no evi- 
dence of any external transverse line; first 
segment of metatarsus equal to or slightly 
longer than combined lengths of segments 
2-4 inclusive. Propodeum somewhat ele-
