prominent; dorsal surface of first tergite rugulose, ventral margins nearly meeting 
at base; remainder of abdomen polished, the combined second and third tergites 
comprising most of dorsal surface; ovipositor subexserted, a little decurved. 
Piceous; face, clypeus, mandibles, and cheeks ferruginous; scape and pedicel 
pan onieh pronotum ferruginous; legs including coxae brownish yellow; wings 
yaline. 
Male.—Essentially like the female but with the head entirely yellow ferru- 
ginous, also the mesonotum and mesopleurum ferruginous. Antennae 16- 
segmented. 
Type locality Jacksonville, Fla. 
Type.—United States National Museum no. 49917. 
Described from 1 female and 2 males, all from the type locality. 
(6) EUPHORUS SCITULUS Cresson 
Euphorus scitulus Cresson, Canad. Ent. 4: 227, 1872. 
Type—In the Academy of Natural Sciences of Philadelphia. 
This species resembles pallipes and levifrons in having the face 
thickly covered with somewhat appressed pubescence, in the presence 
of distinct notauli, and in venation. It differs principally as shown 
in the key to species, and in its smaller size, the type measuring only 
about 2 mm in length, and in the shorter antennae, which are not 
longer than the head and thorax combined and are 16-segmented in 
the type. 
Known only from the unique type, which is from Illinois. 
(7) EUPHORUS LEVIFRONS, new species 
Closely resembles pallipes (Curtis), but is distinguishable by the 
characters mentioned in the key. 
Female.—Length about 3mm. Head transverse but with temples and cheeks 
about as broad as eyes; clypeus broad, polished; malar space a little shorter than 
basal width of mandible; face broader than the distance between antennal 
foramina and base of clypeus, very minutely punctate, subopaque, and thickly 
covered with appressed hairs; eyes large, elongate oval; ocellocular line not dis- 
tinctly as long as postocellar line; frons smooth, without a median carina and 
with only a few. scattered very minute punctures laterally; vertex, occiput, and 
temples impunctate; temples and cheeks carinately margined behind, occiput 
immargined; antennae 23-segmented, longer than head and thorax; first flagellar 
segment fully as long as scape, the following gradually shorter. 
Thorax hardly as broad as head; mesoscutum polished; notauli complete, 
sharply impressed, not distinctly foveolate; impression at base of scutellum large 
and deep, divided by a median longitudinal carina; scutellum convex, polished; 
propodeum rather evenly convex, rugulose reticulate except at extreme base 
laterally; side of pronotum sculptured in the depression, the broad upper and 
lower margins smooth; mesopleurum smooth, with only a few punctures below; 
first abscissa of radius distinct, not punctiform; radial cell not distinctly half as 
long as stigma; metacarpus not extending beyond radial cell; recurrent vein 
interstitial with first intercubitus; medius obliterated; combined median and 
submedian cells hairy. 
Abdomen about as long as thorax and nearly as broad; first tergite broadening 
gradually from base to apex, rugulose punctate, the spiracles behind the middle; 
ventral margins of first tergite approximate at base; remainder of abdomen 
polished; second and third tergites combined embracing most of abdomen beyond 
first segment; ovipositor not, or barely, exserted. 
Black, including face and clypeus; antennae dark brown, scape and pedicel 
brownish yellow; legs testaceous; posterior coxae and their tibiae and tarsi 
weakly infuscated; wings hyaline; stigma brown with a small pale spot at base. 
Type locality —Steamboat Springs, Colo. 
Type.—United States National Museum no. 49918. 
Described from two females bearing C. F. Baker’s no. 1341, and 
recorded as having been taken by him in July.
