shape. Tail of moderate length, about one-third as long as the honey tubes, conical. 
Wings as usual in Siphon opliora ; fourth vein strongly and regularly curved ; second 
fork about equally distant from apex and third vein; stigma elongate, slender and 
pointed, size large. 
General color greenish ; tail greenish-yellow at the base, darker at the tip; body 
greenish or pale greenish-yellow ; antennae dusky. Another winged specimen, proba- 
bly a male, varies considerably from the above description ; the second fork of the third 
vein is very short aud near the apex, and in some cases absent in one wing and present 
in the other. Honey tubes with the enlargement less than the precedin g, and carried 
nearer to the apex; antennae also differ slightly in the respective length of the 
joints. Head and abdomen olive green; thorax and eyes black; antennae dusky, 
legs pale, dark at the knees and tarsi. 
Pupa. — Elongate oblong inform; very pale with a dark green stripe along the 
middle of the back, with apparent whitish powder speckled sparsely over the body. 
Head whitish; base of antennae greenish-white, rest pale fuscous, dark at the tip of 
the joints and at the tip of the antennae ; eyes brown ; femora greenish- white ; tibiae 
fuscous; tarsi darker. Honey tubes long, slender, pale at base and dusky at the tip. 
Tail short, conical, greenish. 
The summer broods of this species are viviparous, but there must be 
a fall sexual brood, containing oviparous females which deposit eggs, 
from which hatch the early spring broods. 
Its Injuries. — This species was first detected in the garden of Col. L. 
W. S pratt. 
The Colonel drew my attention to some sickly tomato vines and 
showed me others that had died and asked me what was the matter 
with them. An examination revealed the Aphids along the stem stalk 
and on some of the leaves, and I feel convinced that these little creatures 
were the cause of the trouble. Their puncture has a blistering and 
blighting effect on the vine, and the leaves curl and wither. 
Natural Enemies and Parasites. — I detected the larvae of a Lace-wing 
(Remerobius) and certain Scymni feeding upon them; also bred from 
them two internal parasites as follows : 
Tomato Aphis Allotria — Allotria megource n. sp. — Female. — Length .03 inch. 
Black, shining. Face testaceous ; autennae long, 13-jointed, subfiliform, dark honey- 
yellow, infuscated from two-tliirds its length to tip; thorax smooth, shining ; scutel- 
lum oval, convex; abdomen globose, slightly testaceous in certain lights; legs dark 
honey-yellow ; wings hyaline, ciliated, veins yellowish. 
Described from one specimen bred May 26th. 
The Tomato Aphis Encyrtid— Encyrtus ? megource n. sp. — Male and Female. — 
Length from .02 to .03 inch. Blue-black. Head finely punctate; eyes large with 
coarse facets; mouth piceous; antennae 11-jointed, covered with short pubsecenco 
in female, in male with two whorls of hairs on each joint; the flagellum gradually 
widens towards tip in female, narrower in male; scutellum slightly metallic in 
female, brighter in male, with some long hairs ; abdomen blackish or brownish, short, 
stout, with long hairs at sides; wings hyaline ; veins yellowish ; marginal vein very 
short ; legs yellowish, coxae, femora except at tip, and a broad annulus on upper half 
of tibiae darker. 
Described from three specimens. 
Remedies. — Those recommended for u Cabbage Aphis ” will be just as 
effectual for this species.
