in Canada; Anasa ulileri Stah, found in Mexico, will probably prove to 
be nothing but a climatic or varietal form of this well-known insect: 
Its Life History — The Egg. — Length, .04 inch; oval, flattened on three sides, so 
that when viewed from either end it has a triangular appearance ; in color it is dark 
golden bronze. To the unassisted eye it is smooth and shining, but when viewed 
under a liigh-power lens the surface is reticulated. 
The Larva . — When first hatched the young bug is broadly oval, with long antennae, 
the joints of which are flat, hairy ; the head, thorax, and wing-scales blackish, while 
abdomen is a bright ocher yellow. Length, .08 inch. 
Its Injuries and Food Hants. — It confines its attacks almost exclusively 
to the Squash and Pumpkin, although it is not improbable that other 
cucurbitaceous vines also suffer from it. 
The bug punctures the leaves and the stem of the vine, causing them 
to wrinkle and wither; also the fruit. 
The eggs are laid in patches, twenty or thirty together, on the upper 
or lower surface of the leaves, fastened to the leaf with a sticky or gluey 
substance, at night or just before dark, for during the day these disgust- 
ing bugs seek shelter in the ground or under trash at the base of the 
vine stalk. 
It is curious to watch them come forth from their hiding places as the 
sun sinks and darkness begins to fall. Brood after brood march up the 
vine, led by an older one, like the different corps of an army march to 
the parade ground at roll call. They come from everywhere — in the 
ground, under grass, trash, and boards. Indeed, it is astonishing to see 
how soon vine -s will be crowded with these bugs, where but a few hours 
before not one could be found. 
Natural Enemies and Parasites. — Birds and fowls, on account of their 
peculiar odor, will not feed on them, and beetles, wasps, and spiders, 
which attack caterpillars and other insects, shun it as a foul thing. 
Fortunately, however, there are parasites that prey on the egg, and thus 
greatly diminish it, although no author that I am aware of mentions 
this fact. It was therefore a surprise and a gratification for me when I 
bred three distinct parasites from the eggs the past summer — a Eupel- 
mid, an Encyrtid, and a Telenomid. 
The Squash-bug Egg Telenomus — Telenomus anasa; n. sp. — Male and Female. — 
Black, very coarsely irregularly reticulately punctate, with white pubescence; 
antennae in female clavate, 12-jointed, brown; in male flagellate, 14-jointed, pale 
brown; legs, pale brown or yellowish brown ; coxae, black ; abdomen in female, ovate, 
sub-convex above, highly convex beneath, and with a light carina at sides; in male 
somewhat fusiform. Wings, hyaline, with a slight fuscous tinge, pubescent, the mar- 
ginal vein very short, post marginal long, while the stigmal is about two-thirds as 
long as post marginal ; all yellowish. 
Described from numerous specimens bred in June and July. 
About thirty per cent, of the eggs collected were parasitized by this 
insect. 
The Squash-bug Egg Encyrtid — Encyrlus anasa ? n. sp. — Female. — Length, .05 
inch; robust; head and thorax blue-black; abdomen and tip of scutellum cupreous; 
the very large pleura and cheeks are decidedly blue ; antennse and legs pale brown ; the
