36 burmeister's odonata. 



Specific acknowle'lgments of having studied Burmeister's types 

 are contained in various papers, and these are quoted, under the 

 respective species, in the detailed list following. 



Arrangement of the Following List. 



The numbers and names of the species follow the Handbuch, the 

 pages of which are quoted. In brackets [ ] is placed the present 

 generic name and, if Burmeister's be a synonym, the accepted spe- 

 cific name. The locality and collection quoted from the Handbuch 

 follow in this type, in which are also printed any further extracts 

 deemed necessary. The present location of the type or types, if 

 known, succeeds, with any ren)arks which they require. The ab- 

 breviations used are B = Burmeister, M. C. Z. = Museum of Com- 

 parative Zoology, Cambridge, (j) see page 31 regarding the labels 

 at Halle. 



The accomplishment of the present work has only been rendered 

 possible by the kindly aid of the late Prof. E. L. Taschenberg and 

 of Mr. Henshaw. I greatly regret the death of the former, in his 

 eightieth year, on the nineteenth of January last. He, his wife and 

 son did much to render my stay in Halle very agreeable, and I wish 

 that he could have received these results. To the Kaiserliche 

 Leopold- Carolus Deutsche Akademie der Naturforscher in Halle, 

 I was also indebted for the loan of several necessary journals to an 

 unknown stranger.

1. Agrion lucretia Dniry. P. 818. [Mecistogaxter.] 



Aus Brasilien, nicht vom Kap, wie Diury sag-t. Ein Weibchen in 

 Sommers Sammlung-. 



The star (*) opposite the name of this species in Hagen's copy of 

 Burmeister is the only, but insufficient, evidence that a female in the 

 M. C. Z. with the label " Lucretia Dry. (libellula) linearis Fab. 

 Brasilia," in an unknown hand, may be the type. This female 

 agrees with the description of 3Iecidogaster lucretia by de Selys in 

 1860 (Bull. Acad. Belg.— 2— x, p. 24). Li 1890, however, de Selys 

 stated (Ann. Soc. Ent. Belg. xxxiv, p. cxix) that his lucretia of 

 1860 ought to take the name of anialla Burmeister. See under 

 No. 3 pod.
