the young appearing first as larvee, then changing to pup, from which the imagos or perfect insect: spring. The humblebees, or bumblebees, of which over 60 species are found ir North America, belong to the genus bomb us, which is almost world wide in its distribution. Of these species solitary females which have survived the winter, commence constructing small nests when the weather begins to be warm enough; some of them going deep into the earth in dry banks, others preferring heaps of stone or gravel, and others choosing always some bed of dry mo . In the nest the bee collects a ma of pollen and in this lays;: ROYAL CELLS. some eggs, The cells in these nests are not the work of the old bee, but are formed by the young insects similarly to the cocoons of silk worms; and when the perfect insect is released from them by the old bee, which gnaws off their tops, they are employed as honey-cups. The humblebees, how ever, do not store honey for the winter, those which survive till the cold weather leaving thé nest and penetrating the earth, or taking up some other sheltered position, and remaining there till the spring.
