PHILIP P. CALVERT. 29 



volume of hi? monumental " Handbuch der Entomoiog-ie," Berlin, 

 1839, T. C. F. Enslin. The systematic portion, which alone con- 

 cerns us here, comprises 171 species, grouped under six genera, as 

 follows: Agrion 32 species, Calopteryx 17, Diastatomma 10 (one not 

 numbered), Aeschna 20, Epophthalmia 9, Libellula 83 (two not 

 numbered). Of these the following numbers were described for the 

 first time: Agrion 19, Calopteryx 8, Diastatomma 2, Aeschna 12, 

 Epophthalmia 6, Libellula 48. 



In the " Vorrede" to this second volume, page iv, in promising a 

 continuation of the work, Burmeister says "auch wird, wie bisher, 

 im Werke selb?t jeder Geber namentlich bei jeder Art aufgefiihrt 

 werden." "Wie bisher" applies especially to the Odouata, for the 

 description of almost every extra-European species is followed by 

 the name of the collection in which Burmeister found the types 

 which he employed. This has added greatly to the ease of locating 

 and identifying his types. The sources of his material, then, which 

 he mentions are the collections of M. C. Sommer in Altona, W. v. 

 Winthem in Hamburg, Prof. Gerraar in Halle, Graf v. Hoffmann- 

 segg in Dresden, and of the University at Halle comprising species 

 from Europe, from South Africa by Drege, and from Hindustan by 

 King through the missionary Schmidt. 



M. C Sommer, described in Hagen's Bihliotheca Entomologica as " Banquier in 

 Altona," was Burmeister's father-in-law (O. Taschenberg I. c. p. 44; Berg I. c. p. 

 317 ; Hagen, Psyche, v, p. 369, July, 1890). His death, " in der letzten Zeil," is 

 barely mentioned in Stettiner Entom. Zeitung, xxix, p. 219, for April-June, 1868. 

 I have not found any published notice of the fate of his Neuroptera, but some 

 are in Cambridge, some in Vienna. 



A "Nekrolog" of Wilhelm v. Winthem (1799-Sept. 2. 1847) is given by Dr. J. 

 Steetz in Stet. Ent. Zeit. ix, pp. 194-198, July, 1848. Hagen. Biblioth. Entom. ii, 

 p. 292, says of his collection "die Neuropteren besitzt H. Hagen." 



Hagen, I. c. i, p. 273, says that Prof. Ernst Friedrich Germar's " Sammlung und 

 Bihliothek sind in Prof. Schaujns Besitz iibergegangen." Hermann Rudolph 

 Schaum was Germar's nephew and published a biography of liis uncle in Stett. 

 Ent. Zeit. 1853, pp. 375-390. Germar's Neuroptera, however, have become some- 

 what scattered, in Halle and in Cambridge. 



Of Johann Centurius, Graf von Hoffmansegg (spelled with one oi two " n " s) 

 (Aug. 23, 1766-Dec. 13, 1849) Hagen states L c. i. p. 374, "Seine Leben von H. 

 Lichtenstein im Dresdener Album von Elfriede von Muehlenfels. Berlin. 1856. 



8. p. 24-44 Seine Sammlung bildet den Schatz des Berliner Museums." 



On his collection see also Entom. News vii. p. 132, May. 1896. His Odonala wliich 

 Burmeister employed seem to have remained in Halle, however. 



Of Drege I have found only one note. In Baron de Selys and Hagen's Mono- 

 graphie des Calopterygines, p. 231, under Libellago caligatn is this: "Synon. Li- 

 bellula nov. sp. No. 1520, Catalogue des insectes recueillis par C. Fr. Drege daus
