volumes between 1856 and 1877,thongli he did not live to complete it. lie wrote many 

 papers on Diptera, and also some on Lepicloptera and Hi/menopfera, which apoeared 

 in different Natural History periodicals, as the Annals of the Entomological Society 

 of France, and in many Italian publications. He described a good many Aphiden, 

 which do not seem to have been known to Mr. Buckton,* and he also published 

 some erudite articles on " Pai-asites and their victims," in the Btli and following 

 volumes of the Bulletin of the Italian Entomological Society. 



Eondani introduced many innovations and new names in his arrangement of 

 genera and species, which are of doubtful value, and have not been generally ac- 

 cepted ; but he possessed a rare talent for the discrimination of species. He seized 

 upon distinctive or characteristic points of structure which others had failed to find, 

 and thus clearly separated many nearly allied species which had been confounded. 

 He also found and described many altogether new species. 



His death so closely following that of the still more celebrated Dipterologist 

 Loew, is a sad loss to this branch of Entomology ; all the older European authorities 

 on the two-winged insects seem gone.

Dr. F. Chapuis. Entomology has just sustained a severe loss — Dr. Chapnis 

 died on the 20tli September, after an illness under which he suffered for several 

 months, but which only became serious a few days before his death. 



Felicien Chapuis was born at Verviers in 1824. His father practiced medicine 

 in that tovni, and, from the commencement of his education, his son was destined 

 to succeed him. Nevertheless, his tastes directed his attention to Entomology, and 

 at the University, all his spare time was employed in the formation of a collection of 

 the Coleopte)-a of the neighbourhood of Liege, where he then resided. I made his 

 acquaintance at that time, that is to say, in 18-J7, and, led by him, I relinquished 

 botany and my herbarium in order to search for Coleoptera in his society. On the 

 advice of Lacordaire, our professor of z ology, we directed our attention more es- 

 pecially to the larvae, profiting by the rich library of that learned entomologist, and, 

 in 1853, appeared our " Catalogue des larves des CoMopteres connnes jusqu' a ce 

 jour." His studies terminated, Chapuis settled at Verviers, and there practised 

 medicine. However, he did not abandon entomology. He undertook the study of 

 Xylopliaga, and published, in 18G5, a Monograph of Platypedes, a considerable 

 work, in which 200 species are described, with figures from his own drawings. 



The death of Lacordaire happened in 1870, leaving unfinished the "Genera des 

 Coleopteres." At the solicitation of the publisher, Chapuis undertook the continua- 

 tion, and, after much assiduous labour, he was fortunate in completing the series, 

 three volumes of that colossal work having been written by him. Chapuis was of 

 sedentary habits : tied by his professional duties, he seldom went out of his native 

 town, and but few foreign entomologists visited him there. Adored by his relations, 

 beloved by his friends, and profoundly esteemed hj his fellow citizens, he passed his 

 days quietly in tlae bosom of his family. 



During his latter years he was occupied in arranging liis collection of CJiry.to- 

 melidcB, and, in anticipation of an intended complete work on the family, he pub- 

 lished, in the Annales de la Societe Entomologique de Belgique, several short 

 monographic papers, and also a Synopsis of Xylophaga. He was a conscientious 

 observer and an assiduous worker, and if death had not arrested his labours, there 

 can be no doubt science would have been favoured with other important memoirs 

 from his pen. — E. Candeze, Glain, Liege : Vlth October, 1879.
