Genus CopmposoMaA Ratzeburg. 
Female.—The antenne arise near the border of the mouth; the scape is long and 
slender; the six-jointed funicle long and slender, or short and comparatively thicker ; 
theclub is either long, delicately bent and somewhat rounded at tip, or it is thicker 
and markedly obliquely truncate. This truncation is produced by the drying ofa strip 
of more delicate membrane upon one sideof the club. Front and vertex closely punc- 
tured, without largerdeep punctures. The mesoscutum and often the scutellum have 
with most species a sculpture which was called by Ratzeburg “schuppig” (scaley), 
and also a thicker punctuation with round or aciculate punctures. The marginal 
vein is either lacking, or it is a little shorter than the stigmal. The wings are hya- 
line. The ovipositor is very long, but may also be entirely hidden. 
Male.—The male resembles the female in the form of the body, in the punctuation, 
and also in the relative proportion of the wing veins, differing to a marked degree 
only in the antenne. These are given off near the border of the mouth as with the 
female; the scape is long and slender, the pedicel shorter than the first funicle joint ; 
the funicle is rather thickly covered with short hairs (the hairs shorter than the 
joints), with the joints separated above more than below ; the club is about as thick 
asthe funicle. The base of the scutellum has a more or less delicate longitudinal 
carina, but no furrow. 
13. (1) Copidosoma gelechiz n. sp. 
Female.—Lenzth, 1.567"; expanse, 3.5™™; greatest width of fore wing, 0.65™™ ; 
antennal club of the obliquely truncate type, as long as the five preceding funicle 
joints together; pedicel of the same length as the first funicle joint; funiele joints 
gradually decreasing in length from 1 to 6. Punctures of head nearly round, of mesos- 
cutum lengthened somewhat longitudinally, of the axille transversely aciculate 
towards tip, broader near base, of the seutellum longitudinally aciculate, especially 
narrow down the median line; ovipositor extruding but slightly; marginal vein 
wanting. Color: Head and pronotum, black, with purplish reflections; antenne, dark 
brown, nearly black throughout, end of pedicel yellowish; mesoscutum, bright 
golden green; axilla, somewhat more subdued; mesoscutellum very dark brownish- 
green, tegule of the same color; abdomen smooth and shining with a greenish luster; 
allcoxe dark green; front and middle legs entirely honey-yellow; hind femora dark 
green, yellow at tip; hind tibia yellow, with a dark band around proximal third ; 
tarsi yellow. 
Male.—Length, 1.6™™; expanse, 3.9™™; goreatest width of fore wing, 0.79™™, 
Antennal club but slightly longer than sixth funicle joint; pedicel nearly as thick as 
long; first funicle joint nearly three times as long as pedicel. Punctuation like that 
of 9. Color: Head, pronotum, and mesoscutum all bright golden-green; axille 
and mesoscutellum, a shade less brilliant; all legs nearly black throughout, with a 
greenish luster, and with the knees yellowish; middle tibial spur and first tarsal 
joint also yellow; remainder of middle tarsi and all joints of fore and hind tarsi 
blackish. 
Described from 4'?’s and 4 ¢4’s bred from the larvae of Gelechia 
galle-solidaginis collected in District of Columbia. The parasites is-

Variety a.— What may be called a variety of this species was bred in 
great numbers by Mrs. Mary Treat from G. galle-solidaginis, August 
8, in New Hampshire. The female of this variety lacks the brownish
