occur as parasites within the bodies of the larva. They 
have been bred by Mr. C. V. Riley, who describes them in his 
fifth Missouri Report. One is a small black fly, from one- 
fourth to one-half inch in length; its legs are reddish, the 
hind pair having a broad white ring. It is called the Ring- 
legged Pimpla, Pimpla annulipes Br. The other species is 
about the same size, but more slender, and of a yellowish or 
brownish color. The female is provided with a long ovi- 
positor. This species is known as the Delicate Longsting, 
Macrocentrus delicatus Cresson. These useful insect friends 
are not yet sufhciently numerous to check materially the 
increase of the codling moth, and it is doubtful if they ever 
will be. When the codling worm has left the frait in which 
it has been feeding, and while wandering about in search of 
a suitable spot in which to pass its chrysalis state, it is lia- 
ble to be attacked by any of the Ground-beetles, (Carabidz), 
both in their larval and their perfect state; also by the larva 
of Soldier-beetles and other carnivorous insects. Some of 
the smaller insectivorous birds are also said to devour this 
insect both in the larval and in the pupal condition.”’ 
THE EYE-SPOTTED BUD-MOTH. 
(Tmetocera ocellana Schiff. ). 
This is also a very destructive insect, the larva of which 
eats into the opening bud of the apple, plum, cherry, black- 
berry and other plants. According to Prof. Fernald, who 
gave a full account of the life-history of this insect: ‘the 
moths pair and the female lays her eggs, when in confine- 
ment, in clusters of from four to ten or eleven, often over- 
lapping each other. They are oval, flattened, four-fifths of 
a millimeter long, and half as wide, sordid white, with a 
narrow border of clear transparent white, while the center 
of the eggs is one complete mass of minute granules. In 
about three days the center of the egg has grown darker and
