1917] Girault—New Miscellaneous Chalcid-Flies from North America 97 
Miscogaster biguttata sp. nov. 
Female: Length, 2.25 mm. Similar to flora but the legs all 
white, the fore wings bear two small, rounded spots, one at the 
apex of the stigmal vein, the other, larger and somewhat quadrate, 
at the base of the marginal vein. In some males, the proximal spot 
is absent and there is a narrow, yellow cross-stripe at about apex of 
proximal fourth. Antenne nearly all yellow. 
From five males, one female with flora. 
Types: Catalogue No. 20791, U.S. National Museum, the speci- 
mens on tags. 
Megorismus poloni sp. nov. 
Female: A third smaller than lasioptere Ashmead and differing 
from that species notably in having the antennze wholly concolor- 
ous except the bulla; also, as follows: the antennz are inserted 
somewhat farther ventrad, on a level with the ventral ends of the 
eyes; the clypeus is stoutly bidentate at the apical meson instead 
of unidentate, as in the other species; the propodeum is subglabrous 
and though tricarinate there is not a cross-carina consisting of three 
ruge which converge at the meson from each side. Segment 2 of 
abdomen occupying nearly a half of the surface; its caudal margin 
at meson with a short slit. Lateral carina of propodeum failing 
just before the cephalic margin. Postmarginal vein more or less 
subequal to the marginal, longer than the slender stigmal. Protho- 
rax distinct. Parapsidal furrows complete, shallow. Scutellum 
with a shallow cross-suture before the apex. Petiole of abdomen 
‘quadrate, reticulate, the abdomen conic-ovate, pointed ventrad, 
about as long as the thorax. Antenne 13-jointed with two 
ring-joints; funicle 1 a little longer than wide, much shorter 
than the subelongate pedicel; funicles 2-4 subequal to 1,6 quadrate. 
Scape long and slender. Tibise at each end yellowish brown. 
Mandibles 4-dentate. 
Described from four females from Placer County, California, 
August (U.S. National Museum). 
Types: Catalogue No. 20792, U.S. National Museum, the speci- 
mens, minutien-mounted and a slide bearing a head and caudal 
tibive. 
In the species lasiopter~, segment 2 of the abdomen is shorter 
than in poloni and its caudal margin is entire.
