194 DE. K.JORDAN: OBSERVATIONS ON DR. VERITY S PAPER. 



description. This note — posterior to 1758, and to the effect that iris has an- 

 ocellus on both wings — may, however, be taken as evidence that Linnaeus- 

 received specimens of the bi-ocellate species after 1758. 



c. Argijnnis ad'qype. — The Linnean description applies equally well to the 

 silver-spotted form of niohe as to the insect generally known as adipjje 

 ( = cydiiype preocc), although Esper (in 1782) was emphatic on the point that 

 the description best fitted the species he figured as adipp)e. If the female 

 from the Linnean collection can be proved to be the one on which the name 

 cydippe was based in 1763, a change of name would be necessary in 

 accordance with the law of strict priority. That proof it will be difficult or 

 impossible to furnish, and some doubt will remain as to whether Esper in 

 1782 was really wrong in figuring as adippe L. the insect known under that 

 name ever since.
