MR. WALKER'S TYPES
Published online by Cambridge University Press: 31 May 2012
Extract
In the Can. Ent., p. 136, Prof. Smith says that our reference of Edema? transuersata, Walk., in 1868, to lignicolor is an error. In other cases e. g. Apantesis radians, etc., our testimony is borne out, and now comes up the question of a changing in specimeus since 1868. Mr. Walker's specimens are not marked type, but placed merely above the label. They can have been changed, and the question is, whether a name of Walker's can be employed which in any way contradicts in its description the supposed species. In my Revised Check List 4, I say: “Clearly there is room for misapprehension of what specimens are really types had we not a check for the reference. This is the criterion for types, that they do not contradict the original description,”
