been sufficiently known or appreciated. Fruhstorfer drew attention tc 

 it and demonstrated it in his work on the Lombok butterflies, thus con- 

 tributing a valuable quota to the common fund of knowledge of ento- 

 mologists. 



After his return from this journey he published his iirst systematic 

 works which formed the basis of his subsequent achievements and, in 

 particular, of Seitz's great work. 



Most collectors in tropical countries either pay with their lives for 

 their fearlessness and enterprise or, upon their return to Europe, are- 

 swindled by the dealers and robbed of the fruits of their labours. Fruh- 

 storfer forms a brilliant exception, for he knew how to retain for himself 

 the profit derived from his toilsome journeys. 



Europe did not, however, long satisfy his enterprising spirit. 



In June 1899 he started upon another journey which lasted the grea- 

 ter part of three years and in the course of which he visited America, 

 the South Seas, Japan, China, Tonkin, Annam and Siam Everywhere 

 he collected with dauntless energy, generally in regions which were 

 partially or wholly unexplored. He accumulated an immense amount 

 of material: lepidoptera, coleoptera and conchyhae, enough to keep 

 research workers occupied for many years to coine. 



In Siam he unfortunately contracted dysentry and this illness put 

 an end to his bold and far-reaching plans. He was forced to return 

 sooner than he had intended, travelling by Singapore, Rangoon, Darjee- 

 ling and the mainland of India. He has described the incidents of this 

 adventurous journey with spirit and humour in his " Tagebuchblatter " 

 ("Pages from my Diary"), a book which is now unfortunately very rare 

 and might be read with enjoyment by the general public as well as by 

 specialists. 



The material gathered in this, the last of his scientific travels, was 

 also plentiful and of the greatest interest and value. 



Fruhstorfer then settled in. Geneva, on the banks of the Arve, close 

 to the French frontier, where he built himself a picturesque home large 

 enough to house his collections. In the succeeding years he pubhshed the 

 results of his researches and of the study of his collections. In addition 

 to numerous descriptions of new species and varieties published in the 

 press, he began to pubhsh his valuable entomological works, monographs 

 on genera of butterflies such as Taenaris, Cethosia, Hebomoia, Elymnias, 

 Mycalesis, Neptis, Athyma and many others. These monographs were 

 subsequently used as a basis for the text of Seitz's work. As a colla- 

 borator in this standard work he certainly ranks, as the greatest autho- 

 rity next to Professeur AuriviUius and Dr. Jordan.
