20, 6 Fouts: New Parasitic Hymenoptera 627 
wider than long, distinctly concave above, smooth and shining; 
pronotum more strongly arched in front, depressed behind the 
cervical plate, across the middle a little wider than long; axille 
more sharply set off from the scutellum by deep grooves; radial 
nervure distinctly shorter than the basal, oblique; anterior ab-

BORNEO, Sandakan (Baker), 1 female. 
Type.—Catalogue No. 24321, United States National Museum. 
Loboscelidia collaris sp. nov. 
Female.—Length, 2.2 millimeters. Head as long as high, 
mostly without pubescence; frons flattened, scarcely excavated 
below, finely and evenly shagreened, carinate laterally, with the 
carina becoming obsolete above, not distinct on the vertex; cheeks 
and malar space finely shagreened; lateral ocelli their diameter 
distant from each other and from the back of the head; an- 
tennal ledge short, bilobed as seen from above, with a lower 
projection, the whole structure of a triangular shape when 
observed from in front; above the clypeus is an acute median 
carina; antenne longer than the body, slender, the joints beyond 
the first subequal in width; scape compressed, slightly narrowed 
basally, seen laterally three times as long as wide, as long as 
the next three joints united; joint 2 as wide as long, nearly 
half as long as 3; joints 3 to 12 subequal in length and width; 
joint 13 longer, almost as long as 2 and 3 united, subacute 
apically ; dorsal cervical plate longer than wide, slightly narrowed 
anteriorly, strongly arched above; space between the head and 
thorax filled by the golden lobes of the woolly substance noted 
in my description of L. antennata; the membranes overlap one 
another and the result is a billowy appearance; pronotum wider 
than long, truncate anteriorly, flattened posteriorly, more or 
less arched in front, with two broad, shallow depressions be- 
hind the middle; mesonotum three times as wide as long, 
shorter than the scutellum, the median lobe shagreened, the 
lateral ones sharply carinate on the outside, each with a sub- 
marginal depression; parapsidal grooves complete; scutellum 
flattened, longitudinally striate; axille separated off by deep 
furrows; postscutellum with a low ridge medially, polished ; 
abdomen as in L. defecta; wings hyaline, with a brownish 
band across the middle of each, and with a pale brown spot 
behind the band along the costal margin; basal nervure slightly 
curved distally, as long as the radius, four times as long as the 
anterior abscissa of the subcosta; nervulus shorter than the
