Order HYMENOPTERA. uf^^v, a membrane ; Tn-spov, a wing. 



The species of Hymenoptera have been estimated at 25,000, but no work 

 has appeared on the whole of the order comparable with the great 

 work of Lacordaike on the Coleoptera. In this country, collectors 

 of Butterflies and of Beetles are more numerous by many times than 

 collectors of the Hymenoptera; yet these, in their biology, are far 

 more interesting than any other order of insects.
