Genus Copidosoma Eatzeburg. 
Female. — The antennae arise near the border of the month ; the scape is long and 
slender; the six-jointed funicle long and slender, or short aud comparatively thicker ; 
the club 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 of a strip 
of more delicate membrane upon one side of the club. Front and vertex closely punc- 
tured, without larger deep punctures. The mesoscutnm and often the scutellum have 
with most species a sculpture which was called by Eatzeburg "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 antennae. 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 
as the funicle. The base of the scutellum has a more or less delicate longitudinal 
carina, but no furrow. 
J.3. (1) Copidosoma gelechiae n. sp. 
Female.— Length, 1.5 mm ; expanse, 3.5 mm ; greatest width of fore wing, 0.65™ m ; 
antenual 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; funicle joints 
gradually decreasing in length from 1 to 6. Puucttires of head nearly round, of mesos- 
cntum lengthened somewhat longitudinally, of the axillae transversely aciculate 
towards tip, broader near base, of the scutellum longitudinally aciculate, especially 
narrow down the median line; ovipositor extruding but slightly; marginal vein 
wanting. Color: Head and pronotum, Mack, with purplish reflections; antenna 1 , dark 
brown, nearly black throughout, end of pedicel yellowish; mesoscutnm, bright 
golden green: axillae, somewhat more subdued; mesoscutellum very dark brownish- 
green, tegulae of the same color; abdomen smooth and shining with a greenish luster; 
all coxaa dark green; front and middle legs entirely honey-yellow; hind femora dark 
green, yellow at tip; hind tibhe yellow, with a dark band around proximal third ; 
tarsi yellow. 
Male.— Length, 1.6 mm ; expanse, 3.9 mm ; greatest width of fore wing, 0.79 mm . 
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 $ . Color : Head, pronotum, and mesoscutum all bright golden-green ; axillae 
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 #'s bred from the larvae of Gelechia 
galke 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. gallce-solidaginis, August 
8, in Xew Hampshire. The female of this variety lacks the brownish
