P52 [November, 



which he gave a short diagnosis of all the then known animals and 

 insects in the Kingdom of Denmark. 



It would be supposed that notice would be taken of such excel- 

 lent Zoological and Entomo'ogical works ; but that has not, unfor- 

 tunately, been the case, especially with reference to the Odonata, 

 which have only been from time to time casually mentioned. This 

 may be accounted for, perhaps, on account of the period in which he 

 lived being contemporary with Linne, and thereby being set in the 

 shade by the greater Naturalist. 



The first, in any case with regard to the Odonata, to draw atten- 

 tion to his work was Dr. [-1. Hagen in '' Synonymia Libellularum 

 Europaearum, Regiom., 1840," and later in " Om V. F. Miiller's 

 Arbejder over Danmarks Odonater'' (Nat. Tidschrift, III R. IB, 

 1861). Unfortunately Dr. Hagen wanted that help that a complete 

 collection of the Danish Odonata could yield. There was in his time 

 no collection or catalogue of the Danish Odonata that could assist 

 in any way, and Dr. Hagen therefore was unable to settle the 

 identity of all Miiller's species. I will not occupy unnecessary 

 space with remarks on those species that have been accepted, namely: 

 Libellula fulva^ Sympetrum sanguineum, u^schna pratensis, jE. cyanea^ 

 and ^. isosceles, \i\xi I will endeavour to continue, on the same lines as 

 Dr. Hagen, to bring forward some of Miiller's names into the place 

 that they should occupy. 



As Dr. Hagen supposed, and of which there is not the slightest 

 doubt, Miiller had Sympety-um striolatum, Charp., before him w^hen he 

 described his Libellula variegata (Enum., No. IG; Fn. Fridr., No. 518; 

 Prodr., No. 1633). 



His description is as follows : L. variegata alis hyalinis puncto 

 marginali ferrugineo ; abdomine flavo rubeoque variegate. 



Descr. Praecedenti similis (Z. san guinea), sed major, differt 

 puncto marginali flavorubenti, pedibusque superne luteis. Nee 

 varietas. Abdomen in fcBmina crassus flaviusque est. 



There can be no doubt that it is a species of the genus 

 Sympetrum, and as Miiller knew all the other members of this genus 

 that are found in Denmark, and as the species is still found in the 

 Frederiksdal district, there can be no longer a question as to its 

 identity. I propose therefore that Miiller's name takes priority, as 

 an Indian species of another genus has the same specific name {Bhyo- 

 themis variegata, Joh.). 



Leucorrhinia duhia, Lind., is described by Miiller under the name
