the ocelli). Pale postocular spots linear cuneiform, broadly separated by black 
from the pale color of the rear of the head, and narrowly separated from, or 
joined with, the pale occipital stripe. Dorsum of the prothorax mainly black, 
a transverse yellow bar on the anterior margin of the anterior lobe, small in- 
distinct pale spots laterally on the posterior lobe, dorsum of the middle lobe 
without pale markings, but with the sides yellow inferiorly. Width of black 
thoracic middorsal stripe, .62 mm.; of pale antehumeral stripe .1—.2 mm.; of 
the black humeral stripe .49 mm. Third lateral suture with a black stripe for its 
entire length, narrowed below. Abdomen all black dorsally, except for a very 
narrow apical (1, 7, 9) or basal (3-7) rings. Sides and venter of abdomen orange 
or yellow. Superior appendages longer than 10, not bifid, resembling those of 
laurenti or signatum. 
The female is unknown.

Length 30 mm. Expanse 38 mm. Mass. and N. J. 
A very dark species, not common. Color black with orange or yellow mark- 
ings. Male. Postclypeus orange, a transverse basal black stripe, trilobed distally, 
the three lobes of varying prominence; or, black predominating, rather broadly 
margined with orange. Frons with pale transverse stripe of its anterior surface 
not attaining the median ocellus, a mere yellow line bordering the ocellus an- 
teriorly. The first two segments of the antennae pale. Vertex black excepting 
two spots anterior to the lateral ocelli. Postocular spots linear, orange, connected 
with each other usually, but not confluent with the pale color of the rear of the 
head. Middle prothoracic lobe in dorsal view, metallic black, usually a small 
yellow spot on each side of the,anterior half. Remainder of the prothorax pre- 
dominantly yellow. Width of the black middorsal thoracic stripe .7—-.77 mm., 
of pale antehumeral stripe .28-.35 mm., of black humeral .42-.49 mm. Third 
lateral suture with a black stripe on the upper three-fourths to two-thirds of its 
length, the stripe continuing as a line the remainder of the distance of the pos- 
terior legs. Abdomen black as follows: dorsum of 1-10; on 2 in the form of an 
orbicular apical spot narrowly connected to the base; on three terminating in a 
sharp point basally; 1 with a wide apical, and 2-7 with narrow interrupted basal 
rings. 
Female similar to the male. Mesostigmal plate (lamina) mostly black, 
margined with the black of the mid-dorsal and the humeral stripes. Width of 
black middorsal thoracic stripe .84-.91, of antehumeral pale stripe .18-.21, 
of dark humeral stripe .48-.56 mm. Third lateral suture with the black stripe 
for its entire length. Black of the dorsum of segment 9 of uniform width.
