Allied to P. ignota Cockerell and P. crawfordi CockerelI,
from each of which it differs, in both sexes, in having the upper
margin of disk of clypeus more or less darkened.
Fentale.-Head and thorax dark olive green, the abdomen blackish.
Disk ofclypeus, except a blackish mark on each side of upper border,
and small lateral face marks, white, the white of clypeus extending
upward in middle, more or less in an ailgle, often to the dorsal margin.
Lateral marks rather roundish, extending only slightly above 'level of
clypeus, usually separated from clypeus by a black sutural line, or by
a broader interval, and sometimes separated also from the eye. Lateral
extensions of clypeus and labrum brown. Mandibles testaceous, becoming
red at apex and white on outer side of base. Scape and pedicel
blackish, the former sometimes with a yellowish line beneath at base.
Flagellum brownish above and dull orange brown beneath. Anterior
border of pronotum, two 'cuneate mal'ks on the hind border, and usually
the tubercles, white. Legs brownish, darker toward base; the tarsi paler,
with small joints sometimes yenowish~ Front and middle knees narrowly,
and front tibiae on anterior side of basal half, pale yellowish. Tergites
2 and 3 with a creamy·white basal band, moderately wide and
even, rather narrowly interrupted medially, that on 3 ending rather
far from lateral I,llargins. .Tergite 4 sometimes with tw.o basal marks
similar to those of tergite 3 bu~ smaller. Rarely a whitish dot on tergite.
l, on eacll side subapically, close to lateral margins, Pygidinm
testaceous' brolvn, truncate at apex. Tegulae pale testaceous, becoming
fuscous on inner margin. Wings whitish hyaline, the subcosta and mar·
gins of stigma pale brown. Frons, vertex, cheeks, and thorax dis·
tinctly tessellate; the vertex and mesonotum rather dull; the face below
antennae, pleura, and .propodeum sbining. Pubescence ratller sparse and
writish. Length, 4·~~5 ·mm.; anterior wing, 3.3 mm.
M ale.-More bluish .green tban female, the propodeum bluer than other
partS'. Abdomen 'bro'wnish black; immaculate; the apical margins of
tergites 2 to 6 wbitisb hyaline. Base of mandibles, labrum, disk of
elyp~~ ~c~p.t !u,ppet- ·b.o.t;lleI:~ . Y-C:l9' small 1~te~1 fa.ce marks~ a.nd SC8:Jl(."beneath, yellowish white. Lateral marks adjacent to clypeus, witlel,Y
separated from eyes and occasionally entirely ubsent. 'I'horax entil't>I~"
dark, or more rarely with a whitish dot on each side of hind bordel' of'
pronotum. Legs blackish, with the knees rather broadly, tarsi, and" fl"Ol1t
tibiae, pale yellow. Head ordinary, not enlarged- in any specimen at
band, the cheeks unarmed or "ith a very s1l1all tooth anteriorly. Other·
