OBITUARY. 

 On the 24th of February died Dr. O. Hofmann, a physician in the 

 Bavarian State service, a well-known Lepidopteristand esteemed writer, in 

 Regensburg, Bavaria. The deceased belonged to a family of entomolo- 

 gists. His brother, the late Dr. Ernest Hofmann, was the author of two 

 illustrated volumes on the European Macrolepidoptera and their larvce, 

 which have already passed through three editions. Dr. O. Hofmann pub- 

 lished a number of papers on the Tineides, and these results of his biological 

 studies are held in great esteem. As a young man he came into contact 

 with Herrich-Schaefifer, of whom he remained an admirer and could re- 

 late many anecdotes. Dr. Hofmann paid much attention to American 

 publications. The observations of Dr. Dyar on the larval tubercles were 

 familiar to him, and he had tried to test them on the European 

 Pterophorid?e, a group upon which he had published and with the trans- 

 formations of which he was remarkably familiar. His death leaves a gap 

 which is felt by earnest students in Europe. His last paper, on the 

 Micropterygides, was read by him last autumn at the Munich meeting of 

 the German Association, and is, I believe, not yet published. One of the 

 kindliest in the short list of my constant correspondents has passed 

 away, whom I shall always miss, but whose future memory in the science 

 may be always assured through his few but excellent contributions to our 

 knowledge.
