In addition to the genotypic species the National collection con- 
tains a single female which appears to be distinct and is described 
below. The two species may be distinguished as follows: 
Abdominal petiole delicately longitudinally sculptured, sometimes nearly smooth; 
posterior wing narrow, longest marginal cilia half as long as the width of wing; 
antennae, and legs including all coxae, mostly yellow; abdominal petiole 
usually; brownish tyellowiee. Ske eee eee (1) incerta (Ashmead). 
Abdominal petiole covered with irregular, more or less confluent punctures, not 
longitudinally sculptured; posterior wing much broader, longest marginal 
cilia not half as long as width of wing; antennae and legs piceous; abdominal 
petiole black 224204. Shy Bene. ee A (2) pacifica, new species. 
(1) EDUPHORIELLA INCERTA (Ashmead) 
(Fig. 1, D) 
Labeo incertus Ashmead, Ent. Amer. 3: 74, 1887. 
Euphoriella incertus Ashmead, U.S. Natl. Mus. Proc. 23: 116, 1900. 
Type.—tIn the United States National Musuem. 
The foregoing generic description is supplemented as follows: 
Length about 1.8 mm. Head smooth and shining; antennae of both sexes 
shorter than head and thorax combined, slightly thickened apically; basal three 
segments of flagellum elongate, slender; fourth and following segments gradually 
shorter and broader, some of them, at least in the female, not longer than broad; 
apical segment larger than that just preceding; mesoscutum and scutellum pol- 
ished; propodeum regulose reticulate; mesopleurum smooth, with a few weak 
punctures below; metapleurum rugose reticulate; hind wing very narrow, the 
longest marginal cilia half as long as width of wing; first abdominal tergite nearly 
four times as long as its greatest width, not wider at apex than at base, weakly 
tuberculate at the spiracles, and longitudinally striate; remainder of abdomen 
polished. Piceous; antennae and legs mostly yellowish; wings hyaline; stigma 
pale brown with a transparent spot at base; abdomen usually yellowish with apical 
segments piceous. 
The type, which is a male (not a female, as stated by Ashmead), 
is from Jacksonville, Fla. In addition, the National collection con- 
tains nine specimens, representing both sexes, from Florida, Maryland, 
the District of Columbia, Michigan, and Texas. The writer has also 
seen a specimen from Illinois in the collection of the Academy of Nat- 
ural Sciences of Philadelphia. Nothing is known concerning the 
habits or hosts of this species. 
(2) EUPHORIELLA PACIFICA, new species 
Distinguished from incerta (Ashmead) as indicated in the foregoing 
key. 
Female.—Length about 2mm. Head large, subquadrate, smooth and shining; 
temples and cheeks at least as broad as eyes; shortest distance between eyes about 
equal to the distance from antennae to apex of clypeus; malar space slightly shorter 
than basal width of mandible; malar furrow distinct; frons shallowly impressed 
on each side behind antennal foramina; postocellar line twice the diameter of an 
ocellus and slightly longer than the distance from one of the lateral ocelli to the 
median ocellus; antennae 14-segmented, not so long as head and thorax combined; 
scape about twice as long as thick; pedicel a little longer than thick; first and sec- 
ond flagellar segments of about equal length, twice as long as thick; the following 
gradually shorter and broader; seventh to eleventh flagellar segments as broad as 
long; apical segment longer, conical. 
Thorax slightly deeper than broad, narrower than head; mesoscutum and scu- 
tellum polished; mesoscutum very sparsely hairy; the large transverse impression 
at base of scutellum divided into two shallow pits by a median carina; propodeum 
rugose reticulate, with a large apical area defined by a strongly arched carina; 
mesopleurum mostly smooth; metapleurum rugose reticulate; venation as in the 
generic description; hind wing not especially narrow, longest marginal cilia not
