Adults taken June 27 were the first observed in the field. _
Eggs were deposited the same day. When confined with a ( 
young plant bearing plenty of food the female deposited
eggs readily. »
The number laid varied from thirty-seven to fifty-two.
They were generally deposited in a clump, and were
‘ attached to the under sides of leaves, in confinement some-
times to the sides of rearing jars. In the field they were
well concealed from view. In the Insectary the egg-laying
period did not extend over three or four days, tho the
adults lived for a longer period. _
It became evident that there are at least three broods of i
the species duringa season. The latest brood appeared as
adults on October G, 7 and 8, and all efforts to induce them
to lay failed, as did attempts to secure eggs from adults `
taken in the Held. It was evident that they were ready to
hibernate as adults. No larvae were found after October 6.
From the shortness of the life-period it is possible that a _.
brood had already developed when the work of rearingin ` 
the Insectary started. From the eggs secured June 27
adults developed in 24.5 days. The next brood was com-
plete in 24 days, and a little more. July 27 the third brood
was complete, the shortening of the last period being
probably a result of a great abundance of food.
The hibernation of the insect has been observed by us for
many years. Sometimes large numbers of the adult beetles
have been found concealed under boards, stones and logs in
sheltered places.
p Hippodamia convergens.
This is a brown beetle, the head and thorax black,
marked with white, the wing covers yellowish brown,
each with six black spots, the three anterior smaller,
the two median much the largest. Beneath, largely black.
Length about (5 mm. It is found everywhere in Kentucky,
and has been observed about corn silk, where with the pre-
ceding speciesit eats the eggs of the corn-ear worm. At
Hickman it was found on corn in about equal numbers
with JIU]/lvll(I mawula/a.
