black, middle tibiae slightly suffused with rufous but hind tibiae 
black and whitish, middle and hind coxae with a small amount of 
rufous above). There is no question at all in my mind that these 
three specimens are conspecific. 
4. Epipompilus bifasciatus (Ashmead) new combination 
Aulocostethus bifasciatus Ashmead, 1902, Canad. Ent., 34: 132 [Type: $, 
Bahia, Brazil, 19 March 1883 (but stated by Ashmead to be “Peru”) 
(U. S. Nat. Mus., no. 58858)]. (Not Aulocostethus bifasciatus of Haupt, 
1930; see no. 8. insolitus n. name). 
Description of type female. — Length 11 mm., fore wing 8.7 mm. 
Head black ; inner orbits narrowly pale yellow up to emargination of 
eyes; antennae wholly brownish, darker apically; apical half of 
clypeus and labrum pale yellowish; mandibles dull rufous; palpi light 
reddish-brown. Thorax rufo-castaneous, except mesonotum with 
black streaks over wing bases, and the following pale yellow : posterior 
lobes of pronotum, extreme lower posterior corner of mesopleurum, 
posterior rim of propodeum (interrupted medially), and apical pos- 
terior parts of middle and hind coxae; legs otherwise reddish like 
thorax, middle and hind tibiae weakly infuscated, spurs all whitish. 
Abdomen black, spotted with pale yellow (almost white) as follows: 
two large lateral spots on tergite two, two much smaller spots on 
tergite three, two spots on tergite four slightly larger than those on 
three, two large spots on tergite five broadly connected by a basal 
band; also sternites two and three with small lateral spots. Wings 
bifasciate, hyaline with a strong band over the basal and transverse 
median veins and a broader band filling the marginal cell and extend- 
ing to the posterior wing margin. Body and legs clothed with short, 
white hair; eyes short-haired. 
Clypeus broadly truncate; labrum small, exserted. First four 
antennal segments in a ratio of about 13:5:11:12, segment three .55 
X upper interocular line. Head 1.2 X as broad as high; middle inter- 
ocular line .57 X width of head; upper interocular line .8 X lower 
interocular line. Ocelli in a broad, flat triangle, front angle greater 
than a right angle; postocellar line much greater than ocello-ocular 
line. Pronotum of moderate length, posterior margin subangulate. 
Propodeum with smooth contours except posterior slope finely trans- 
versely striolate and with rather long pubescence; median line not 
impressed. Posterior tibiae without spines. Fore wing with basal and 
transverse median veins interstitial; radial vein somewhat angulate at 
junction of second intercubital vein, marginal cell removed from wing- 
tip by about .7 its own length. 
Remarks. — - This is a rather typical member of the genus, in fact
