burmeister's odonata. 



I'Afrique meridionale (redige par Erio.hson), Hamburg 1841." On p. 233, I. c. the 

 name is spelled Drege. Burmeister's types from this collection are in Halle, but 

 other Odonata from Drege are in Berlin, Baron de Selys' collection at Liege, and

 which measures 20 x 13 millimeters. Such labels are represented in 

 the accompanying figures A-E, which have been produced by tracing 

 some original labels and photographing these tracings, as experiment 

 showed that the paleness of the ink and the color of the labels pre- 

 vented the obtaining of good results by direct photography. For 

 the labels in question I am also indebted to the late Prof. Taschen- 

 berg, who, in transmitting them, wrote, under date of 14. 9. 97,
