The folloM'ing variant. 
Fe male: — Length 2,00 mm, excluding the 
ovipositor which is extnided for a length equal to V3 
that of the abdomcn. Like californicus but much 
smaller and the legs (except the tarsi) and the antennae 
are all dark. Mandibles tridentata. (Lateral carina 
on propodeum not seen.) 
Described from one female on a tag in the U. S. N. 
M., labelled ,,Easton Washington. K.", 
A common species throughout the United States 
and variable. 
Coelopisihia intermedia new species. 
Female: — Length 3,30 mm. 
Differs from Coelopisfhia gelechiae Howard in 
being much broader and the lateral carina of the 
propodeum forks narrowly in this species as it runs 
into the spiracle. From cladiae Gahan in the same 
particulars and the pedicel is light yellow and the 
spiracle of the propodeum longer. From chionobae, 
clisiocampae and diacrisiae Howard as from cladias; 
also diacrisiae lacks the lateral carina. From neme- 
tic.ida similarly and in having the pedicel light ; n-ima- 
ticida has an obscure lateral carina. Dark metallic 
green, the legs, pedicel and scape yellowish brown, 
the rest of the antennae black, the wings hyaline, 
the venation very pale, the postmarginal vein slightly 
shorter than the stigmal. Occipital margin of the 
large head rimmed or margined (as seen when the head 
is romoved). Scape very long and slender, the pedicel 
elongate; ring-joints large, the second a little longer 
than Wide, the first somewhat wider than long; funicle 
1 a little longer than wide, 6 wider than long, 1 about 
half the length of the pedicel. Abdomen flattened, 
distinctly wider than the thorax, almost round from 
dorsal aspect. Parapsidal furrows incomplete. Ab- 
domen broad. The club beras an apparent fourth Joint. 
Described from one female on a tag in the U. S. 
N.M., labelled „Washington, D. C. June 27, 1887". 
Type: Catalogue No. 19 676, U. S. N. M., the 
specimen on a tag plus a slide bearing a head and 
hind leg. 
Coelopisthia hicarinata new species. 
Female: — Length 3,30 mm. 
The same as the preceding but differing in having 
two lateral carinae on the propodeum which are not 
parallel but dosest at the spiracle and widest apart 
about centrally, then converging but not so closely 
as proximad. Also tho median carina Ih delicate and 
gives off ol)lique rugae, Hoine of tho bitter also origi- 
nal ing at the C('i)halic margin. 
The male is siinilar excc])t that the antennae aro 
light yellow, the ])edicel shorter and there is but one 
lateral carina on the propodeum which 1oo])h up at 
the mcson to meet the abbreviated median carina. 
Part of the second (or lateral) lateral carina is ])reHent 
caudad where it is marginal and long but joints the 
mesal of the two before the spiracle. 
Described from three pairs in the U. S. N. M., 
labelled „No. 4020. .luly 28, 1882." and placed with 
the preceding species. 
Type: Catalogue No. 19 677, U. S. N. M., the 
above specimens plus a slide bearing a head and 
a caudal tibia. 
Merisus carinatus new species. 
Female: — Length 2,65 mm. 
Black with slight aeneus tinges, thc wings hyaline; 
coxae concolorous, the femora dark brown, sub- 
concolorous, the flagellum brown (pedicel blackish 
mostly), the scape light brownish yellow; tarsi and 
tibiae along distal half, white, the distal tarsal Joint 
dusky. Club of antennae yellowish white, solid, 
acutely conical but not spined. Characterized by the 
propodeum which bears a complete, delicate median 
carina but is otherwise normal. Funicle 1 longest, 
a half longer than wide, slightly longer than the 
pedicel, 6 somewhat wider than long, 3 quadrate, 
2 somewhat longer than wide. Mandibles 3- and 
4-dentate. Venation pale yellow, the iJostmarginal 
vein elongate, distinctliy longer than the slender 
stigmal. Parapsidal furrows slightly over half complete. 
The male is about the same but much less robust, 
the antennae whoUy black, the median carina of the 
propodeum lacking. Funicles 5 and 6 are quadrate, 
the club 3-Jointed, the pedicel much shorter than 
funicle 1 which is somewhat longer than in the female. 
Male club not conical, with a niinute terminal bud. 
Otherwise as in other North American species. 
Described from two males, one female in the 
U. S. N. M., labelled ,,Parapteromalus isosomatis 
Ashmead. cj$. T>T)e No. 12 727, U. S. N. M., Webster 
No. 1895. From Elymus canadensis. From Webster, 
Uibana, Illinois, August 11, 1902". 
Type: Catalogue No. 12 727, U. S. N. M., the 
above specimens on tags plus a slide bearing female 
head, caudal les and fore wing and a male oaudal 
leg and head. 
Parapteromalus Ashmead has never been properly 
described, since itg genotype was never described. 
Spalangia muscidarum Richardson stomoxysiae 
new variety. 
Female: — Length 2,50 mm. 
In Richardson's (1913) table to the North American 
species runs to rugosicollis Ashmead but when com- 
pared with the tjrpe of that species differs as follows: 
The punctures of the head are smaller, scattered, the 
space between them smoth (the neck of the pronotam 
is scaly), the pronotum is glabrous, with numerous, 
larger, scattered punctures and a transverse row of 
punctures- limits these near caudal margin; the 
cephalic half of the scutum (except laterad) is glabrous
