“ All our entomological collections are determined by distinguished specialists, and I prefer to await the offer of assistance rather than to solicit it. When the insects are determined each receives a label with the name of the verifier and the year when verified, and a number is attached to the species repeated with all specimens, corresponding to the name given by the specialist, which name is written in a register-catalogue. ”

“ If a second specialist should study the same insect his identification is indicated on another label without any change of number if his verification should agree with the former one. A new number below the former number indicates a divergence of opinion between the specialists. After a certain time the insects so studied will have a great scientific value and the collection a strikingly typical status. ”
