The Butterflies of Noeth America : by W. H. Edwards. Third Series, 

 Part xiv, with three Coloured Plates. Boston and New York : Houghton, Mifflin, 

 and Co. London : Triibner and Co. 1893. 



This Part commences with a consideration of Neominois Ridingsii, Edw., an 

 tilpine Satyrid allied to Chionohas. The details concerning it occupy eight 4fco 

 pages, illustrated by a plate on which are about 30 figui'es. Otherwise the Part is, 

 like its predecessor {cf. Ent. Mo. Mag., 1893, p. 49), occupied by the genus 

 Chionohas itself, and the species treated on are Ch. (Eno, Boisd., of which assimilis, 

 Butl., is considered a variety, Macounii, Edw., which appears practically peculiar to 

 the Doininion of Canada, and of which the transformations are elaborately detailed 

 and equally elaborately figured.

Prof. Hermann August Hagen, Eon. F.E.S., was born at Konigsberg, East 

 Prussia, on May 30th,* 1817, and died at Cambridge, Mass., U.S.A., on November 

 9th, 1893. He was the son of K. H. Hagen, one of the Professors at the University 

 of Konigsberg, and after preliminary education entered the University as medical 

 student, where Rathke was Professor of Natural History, and it is possible that this 

 association had much to do with his turning his attention to Entomology ; but I 

 have evidence that his father, although he appears to have written nothing on the 

 subject, was an entomologist, for in 1865 Hagen sent me a pair of the still rare 

 dragon-fiy, Epitheca bimaculata, " as a true token of my friendship," inasmuch as 

 they had been captured by his father, who gave them to him at the age of 15, with 

 advice to study such insects. In 1839 he sent a List of the Dragon-flies of East 

 Prussia to a local publication, and in the same year he appears to have accompanied 

 Kathke on a journey to Sweden, Norway, Denmark, &c., where the principal collec- 

 tions and Museums were visited. In 1840 he wrote his " Dissertatio Inauguralis," 

 the subject of which was tlie synonymy of European Dragon-flies, proving unmis- 

 takeably that talent for bibliographical research for which he subsequently became 

 so famous. Once fairly launched as a writer, articles from his pen followed in rapid 

 succession, and at the time of the attack which ultimately proved fatal, they numbered 

 many hundreds, mainly on Neuroptera, including, for many years, critical reviews 

 on all papers on the subject that appeared, and also notices of old and nearly forgotten 

 works on entomology. Fossil Neuroptera engaged his attention continuously. Un- 

 doubtedly he was the pioneer of inodern Neuropterology in its broad sense, and of 

 Trichopterology in particular. About 1841 his work attracted the attention of 

 Baron de Selys-Longchamps, and the life-long friendship then formed showed fruit 

 in the production of the " Revue des Odonates d'Europe " (1850), which was in 

 part written by him, and to which he contributed nearly all the illustrations of 

 details, for he was a ready draughtsman, and his letters were always rendered the 

 more valuable on account of the intercalated sketches. With de Selys he was 

 was also associated in the " Monographie des Calopterygines " (1854) and " des 



* In his "Inaugural Dissertation" (1840) he gives the date somewhat vaguely as " *nte 

 tertium diem Jun., anno 1817," showing that, at that time, he was slightly uncertain.
