Too Long; Didn't Read

If further proofs than those submitted elsewhere were needful, to demonstrate that the organ does not imply the function, that the implement does not determine the work,1 the Odynerus group would furnish us with very remarkable evidence. With a close similarity of organization, not only in the details but also in the aggregate, a similarity which makes these insects one of the most natural genera in respect of structure, they possess a great variety of industries, bearing no relation one to the other, though carried on with the same equipment. Apart from the likeness in form, one single characteristic unites this group, whose habits are so unlike: all the Odyneri are game-hunters; they victual their families with grubs paralysed with the sting, with little caterpillars and small Beetle-larvæ.
