28 burmkis'I'Er's' odonata. 



the greater part of five days, May 26 to 30, 1896, in Halle, in 

 studying the collection of Odonata there. The idea was then formed 

 of listing and studying, as far as possilile, all Burmeisterian types 

 of Odonata, whether of Orthetrum or other genera. A brief state- 

 ment of the results appeared in " Entomological News," volume viii, 

 page 6, January, 1897. 



But by no means all of Burmeister's Odonata exist in Halle. 

 Correspondence developed the fact that other types, which had passed 

 into the possession of tlie late Dr. H. A. Hagen, were to be found 

 in the Museum of Comparative Zoology at Cambridge, Massachusetts. 

 These were rendered accessible to study by the kindness of Mr. 

 Samuel Henshaw, Curator for Insects, and a considerable part of a 

 visit to Cambridge made between July 15 and August 4, 1897, was 

 employed in examination of them. 



The Aim of this Paper 

 is therefore to give as complete a list as possible of the present loca- 

 tions of Burmeister's types of Odonata, together with detailed de- 

 scriptions of those species whose identity is more or less uncertain. 

 These cases are mostly of the subfamily Libellulinaj, for in the other 

 subfamilies most of Burmeister's species have been studied by Dr. 

 Hagen or Baron de Selys-Longchamps, and their I'esults recorded. 

 Citations of these records are- given in the following pages under the 

 respective species. 



Burmeister's Work on the Odonata, and the 



Sources of his Material. 



Karl Hermann Conrad Burmeister, born in Stralsund, Jan. 15, 



1807, died in Buenos Aires, May 2, 1892,* published but one work 



on the Odonata, and this is contained in pages 805-862 of the second 



* The most extensive biographical notice is by Dr. Carlos Berg, in Spanish, in 

 the Anales del Museo Nacioual de Buenos Aires, vol. iv, pp. 315-357, 1895; it 

 contains also a chronological list of his publications on all subjects. Dr. Berg 

 gives a shorter '"Notice Necrologique," in French, in Anuales, Soc. Entom. 

 France, Ixiii, pp. 705-712, with a list of Burmeister's entomological works; both 

 of these are accompanied by a portrait, and both are to a large extent based on 

 Dr. O. TaschcTiberg's biography in LeopoJdina xxix, pp. 43. 62, 78, 94. Halle, 

 1893. Shorter sketches are to be found in Entom. Monthly Magazine, London, 

 xxviii, pp. 221-22, August, 1892, by R. McLachlan, and in Entomologische Nach- 

 richten, Berlin, xviii, pp. 220-222, July, 1892 (anonymoasj. In the Anales Soc. 

 Cientif. Argentina, xxxiii, pp. 145-150, is an account of the "' Exequias funebres 

 del Doctor German Burmeister," consisting chiefly of a "Discurso del Ministro 

 de Instruccion rublica. Dr. Juan Balestra."
