The occurrence ofparthenogenesis in Cynips, and in some of the wasps and bees,hasbeen proved; and it has been noticed that the workers orwingless adults are probably the result of this process. They arewithout the power of reproduction, and thus their metamorphosisis a stage mor6 imperfect than that of Cynips aptera. Very little of the intense activity and instinct of the Hynicn-optera appears to be squandered upon the pleasures of the adults,and every unusual gift and habit they may have, with nearly alltheir restless industry, are employed in one direction—in per-petuating the species and in preserving the young during theirtransformations. All the honeycomb making, the excavation ofnests, and the building-up of subterranean edifices, are for thepreservation of the feeble larvae and still more helpless pu[); CHAPTER VII. THE COLEOPTERA—BEETLES. The Coleoptcra are those insects which are commonly calledbeetles. There are great numbers of them, and perhaps theyhave been more carefully studied, so far as their specific differencesare concerned, than any other insects. More pains have beentaken to collect them than have been given to the discovery of anyother orders, and special collections have been formed by a greatnumber of amateur naturalists, who have searched the whole worldover for these objects, which appear to be so very interesting tothem. Books which contain simple descriptions of the Colcopteraappear year by year in the different countrie
