Previous Studies of Burmeister's Types. 



General acknowledgments of aid received by subsequent students 

 of Odonata from Burmeister himself, or those whose collections he 

 used, are contained in 



De Selys and Hagen : Revue des Odouates ou Libellules d'Europe, Liege, 1850, 

 page 265, 266, from Burmeister. 



The same : Monographie des Caloptei'ygines, Liege, 1854, p. viii, Sommer at 

 Altona, Schaum at Berlin, and Burmeister. 



The same: Monographie des Gomphines, Bruxelles. Leipzig, Paris, 1858, p. viii. 

 Schaum at Berlin, Burmeister at Halle, Sommer at Altona. 



Hagen, H. A. Synopsis of the Neuroptera of North America, Washington, 

 1861, p. vi. " Species collected in South Carolina by Mr. Zimmermann, and fur- 

 nished by the late Prof. Gerniar of Halle. . . . My own collection, containing 

 the types of Winthem, described by Prof. Burmeister. . . . Some types, chiefly 

 from Labrailor, described by Mr. Burmeister, and contained in the collection of 

 Mr. Sommer at Altona."* 



* On the same page vi is the statement "Where an (!) has been added to the 

 name of the author, I have seen the types which he described." It is necessary 

 to be cautious in applying this information, however. On page 79 of the book, 

 such a ! is added to Burmeister's name following "Agrion discolor," yet on page 

 80 it is said of the same species "unknown to me." The latter statement is 

 probably correct.
