LINNEAN TYPES OF PAL^ARCTIC RHOPALOCERA. 179 



the name helia in the place oE eupheno, on the ground that Linnseus's 

 description of the former might have been meant for another Algerian 

 specieS; T. omphale. This view cannot stand if one remembers that in the 

 times of Brander no European had ever got to the southern desert regions 

 haunted by omphale. 



*Leptidea sinapis [1758]. The specimen labelled by Linnseus is a male 

 of the spring brood with very large diffused apical patch of grey at apex and 

 very abundant and dark scaling on underside of hind wings ; another 

 specimen is a male of the summer brood, very near the form known as 

 <ifm'g?isz5, Boisd., and bears the locality "Hung." in Linnteus's handwriting 

 (it is the only Linnean specimen I have seen with a locality attached 

 to it!). 



The original description of this species applies as well to the summer as 

 to the spring brood. The specimen which has been labelled by Linnseus is 

 to all appearance Scandinavian, and, strictly speaking, it probably ought 

 to be taken as the type, because Linnseus presumably only received his 

 Hungarian insects after the X. edit, of Syst. Nat. was published ; this may 

 be inferred by the fact that he gives the habitat Hungary for P. mnemosyne 

 only in the XII. edit. 



This consideration does not seem, however, to be of sufficient value to 

 oblige us to drop the well-known name of lathyri, Hiibn., for the first brood. 



*Colias pal^no [1761]. The specimen bearing the Linnean label is in 

 no way the insect which is known under this name ; it certainly belongs to 

 the same group, having the underside of hind wings thickly suffused with dark 

 scaling, and a silvery discoidal spot devoid of any ring, but its bright yellow 

 upperside and narrow marginal band with a slightly undulating inner margin 

 and yellow veins partially intersecting it distinguish it promptly ; the only 

 butterfly I could refer it to is the American alexandra, Edw., whose habitat, 

 however, makes it highly improbable that Linnseus should have obtained it. 

 Two more specimens, which are unmistakably Linnean, are a male and a 

 female of the Scandinavian race of palceno. 



As the original description is in ' Fauna Suecica,' I should think there 

 was no doubt that Linnseus meant it for the butterfly of his country which he 

 was well acquainted with, and there is no reason to alter the present 

 nomenclature. 



*OoLiAS HYALE [1758]. Two males and a female, which all have the 

 look of Linnean specimens and seem to be of the summer brood. 



*GoNEPTERYX RHAMNi [1758]. The Linnean specimen is a male of the 

 northern race : small, light yellow, discoidal spots so small and pale as to 

 be nearly invisible.
