These notes froni a niunber of females rcared from 
Chiloconis bivulnerm. Hart, Michigan August 30, 1915 
(S. A. Johnston). 
Subfamily Eutedouinae. 
EmersoneUa new genus. Entedonini. 
Fe male: Head (cephalic aspect) rounded tri- 
angulär, the antennae inserted below the middle of 
the face on a level with the ventral ends of the eyes, 
8-jointed with one short ring-joint, the club solid. 
Pronotum not \asible from above. Parapsidal furrows 
short, cephalad only. Abdomen subsessile, neariy 
round, depressed, about as long as the thorax, its 
second segment occupying a third of the surface, the 
third Over half the second's length. Axillae not ad- 
vanced. Propodeum with a very minute, round spi- 
racle and a curved lateral carina which is farther 
mesad than usual (really a pair of widely separated, 
convexly curved median carinae); no other caiinae, 
except a very delicate, lateral carina (from the spi- 
racle). Marginal vein a half longer than the sub- 
raarginal, the postmarginal vein short, half the length 
of the moderately long (for the group) stigmal. Mar- 
ginal fringe of the fore wing not short as usual but 
distinctly somewhat longer (not a seventh of the 
greatest vving Avidth). Mandibles with two outer 
(upper) acute teeth (the second the longer), and four 
inner, equal, minute ones. Caudal tibial spur normal. 
A distinct depression on each side caudad on scutum 
at the parasidal furrows. 
EmersoneUa lemae new species. Genotype. 
F e m a 1 e : — Length, 0,55 mm. 
Dark metallic blue, the wings subhyaline, the 
venation dusky yellow; scape, first two tibiae, knees, 
tarsi and tips of caudal tibiae, dusky yellow. Thorax 
moderately coarsely reticulated except the propo- 
deum. Abdomen glabrous (at least segments 2 and 3). 
Head glabrous. Pedicel a little longer than wide 
at apex, subequal to the subecpial funicle joints which 
are oval and somewhat shoiter than the club, the 
latter with a distinct terminal nipple, subovate, about 
twice longer than wide. Flagellum with a few, delicate, 
tolerably long setae. Caudal wings with about six 
lines of discal cilia were mdest, acutely knife-shaped, 
the part distad of venation the shorter, the caudal 
marginal fringes not so long as the greatest width. 
Distal tarsal Joint dusky, longest. 
The 2iiale is about the same, the funicle joints 
slightly shorter. 
Described from one male, eight females reared 
from the eggs of Lema trilineata, Washington, D. C, 
Sept. 24, 1915 (F. H. Chittenden). 
Type: Catalogue No. 19991, U. S. N. M., the 
above specimens on tags plus a slide with male and 
female heads, female wings and caudal legs. 
Pseudacrias sexdentatus new si:)ecies. 
Female: — Length, 1,15 mm. 
Very dark metallic blue, the first three tarsal joints 
white, the wings hyaline. Venation brownish. Man- 
dibles 6-dentate. Hind tibial spur rather long, subequal 
in length to the first tarsal Joint. Funicle joints sub- 
globular, subequal, smaller in succession, the first 
a little shorter than the pedicel, smaller than club 
1 which is wider than the pedicel and as long. Ter- 
minal nipple of club distinct. Parapsidal furrows 
mere sutures, caudad terminating in a foveate im- 
pression. Middle of the three median carinae of pro- 
podeum absent, the lateral carina dividing at each 
end and running in both directions along the margins. 
Petiole distinctly wider than long. Propodeum gla- 
brous except in extreme laterocephalic corner. Cepha- 
lic margin of pronotum carinated. Thorax scaly 
reticulated, the pronotum laterad smooth or neariy, 
fine and longitudinal on scutellum proximad, becoming 
coarser and coarser distad, the lines raised there. 
Segment 2 of abdomen occupying between one thiid 
and one half of the surface, the segments scaly reti- 
culated (segment 2 smooth at proximal one half). 
Petiole smooth . Tips of tibiae faintly pale. Abdomen 
cordate. 
Described from two females marked ,,1256" and 
stated by Professor J. T. Patterson to be an associate 
of Gnorimoschema salinaris, Woods Holl, Massachusetts. 
Type: Catalogue No. 19992, U. S. N. M., two 
females on tags. 
The mandibles are bidentate in Pleurotropis rugosi- 
thorax Crawford, the teeth subequal (type examined). 
Secodella rugosus Crawford rubriscapus new variety. 
Female: Dark metallic purple, the wings hya- 
line, the scape reddish brown; apex of the tibiae and 
the tarsi (except last Joint), whitish. Venation dusky 
black. Funicle 1 subequal to the pedicel, 
about a half longer than wide, 2 a little shorter than 
it, 3 subquadrate, 4 somewhat wider than long. Man- 
dibles with three acute teeth in both forms. Otherwise 
as in rugosus. One female, Prince George County, 
Maryland, October, in grass and forest. Compared 
with types of the tj^pical form. 
Type: Catalogue No. 19993, U. S. N. M., the 
above specimen on a tag, the head, a fore wing, a hind 
leg and a cephalic tibia on a slide. 
The color of the species is of course metallic. In 
this genus there is a row of moderately lojig slender 
setae from the upper (dorsal) surface of the fore 
wing, opposite the middle of the marginal vein and 
quite near the latter. In the new variety just de- 
scribed there are but six setae in this row but the 
number must vary considerably. The club is rather 
short and broad. 
Subfamily Eulophiuae. 
Sympiesis doUchogaster Ashmead. 
Female: — Length, 5,00 mm. 
Abdomen long and slender, stylate, somewhat 
over twice the length of the thorax, purple. Dark 
metallic green, the wings hyaline, the venation dusky, 
the legs and scape white (except proximal third of 
the long caudal coxae and the dorsal edge and apex 
of the scape). Tegulae white. Body densely scaly 
punctate, the propodeum and cbdomen scaly, the 
former with a median carina only, no neck, the ab- 
domen sessile. Legs slender. Pedicel hardly longer 
than wide, much smaller than any funicle Joint;
