eludes : "the species o'i Sympctrum are perfecil}- distinct ; the remainder 

 of the genera and species will, I believe, stand." 



In Zoologist, 1845, vol. Ill, p. IC44, he mentions Sympetrum riifo- 

 stigma. Entomologist, vol. I, 1841, p. 159 and p. 205, .S. rubicund e x?, 

 mentioned by Mr. Doubleday. 



I find Mr. Newman's genera only twice quoted by British Scientists.' 

 Mr. J. F. Stephens, Mandibulata, vol. IV, 1836, gives «o/ as genera but 

 as subgenera or subgroups the four names with the short characters of 

 Mr. Newman, and of the new species of the monograph of Sympctrum 

 he quotes only one. Mr. J. O. Westwood, in " Synopsis of the Genera 

 of British Insects,"' 1839, p. 48, after the genus LibeUula puts in brackets 

 the four names and one species to each of them. As he has counted for 

 LibeUula 1 5 specimens it is evident that he did not accept Newman's 

 genera. 



It is difficult to understand now why some of Mr. Newman's papeis 

 were not acknowledged or at least not mentioned bv English Scientists ; 

 however it seems to me out of place to speak here about things happily 

 forgotten fifty years ago. 



Mr. VV. E. Evans British Libe'.lulinae, London, 1845, "^es Diplax 

 from the nomenclature of Charpentier, and mentions nowhere Sympetrum. 

 It is impossible that this work was unknown to Mr. Newman. Zoologist, 



1845, p. 1044, he speaks of the presence "of Mr. Selys m London, en- 

 gaged in examining the cabinets of the London collectors, for the purpose 

 of correctly ascertaining under what names the various species of A/Z'^V/w/rt' 

 have been described by British Entomologists." 



Baron De Selys paper, pul)lished Annals and Mag. of Nat. Hist., 



1846, p. 217, is reprinted by Mr. Newman, Zoologist, 1846, p. 1522, 

 but nothing is said in favor of his genera, which are not even mentioned 

 in this paper. 



Entomologists nowadays will scarcely be able to understand the diffi- 

 culties, which impeded the working fifty years ago. There was no con- 

 nection to speak of between Scientists of Great Britain and the continent. 

 In 1843 1 found Stephens" Brit. Entom. and Curtis wanting in the libra- 

 ries of Berlin, Vienna, Paris and of the Jardin des Plantes. The only 

 copy in Germany belonged to the Senator von Hayden in Frankfurt a. M., 

 which Erichson was allowed to consult. There did not exist any yearly 

 Record ; the first was published 1834 in Wiegman's Archiv by Burmeister. 

 The first Presidents Address of the Entomological Society by Mr. Children 

 was published for distribution among the members ; the first Address of 

 the Secretary, Mr. Westwood, contains nothing on Sympetrum. The 

 existence of the Entomological Magazine was nearly unknown on the 

 continent. Percheron, Bibliography, p. 225, quotes it ''per Walker the
