The New Head of the Department of Zoology and Entomology, 



Ohio State University. 



Professor Raymond C. Osburn, of the Connecticut College, New 

 London, Connecticut, has been elected Head of the Department of 

 Zoology and Entomology of the Ohio State University, his appoint- 

 ment to take effect July ist. He will assume the duties carried during 

 the last nineteen years by Dr. Herbert Osborn, who was last year 

 elected Research Professor and who will hereafter give his entire 

 time to research work, including a direction of research work by 

 graduate students, and, for the present, the Directorship of the Lake 

 Laboratory and of the Ohio Biological Survey. 



Dr. R. C. Osburn graduated from the Ohio State University in 

 1898, received a Master's degree from the same institution in 1900, 

 and the Ph.D. degree from Columbia in 1906. Fie has been connected 

 as a teacher with the Starling Medical College, Columbus, Ohio ; 

 Fargo College, Fargo, North Dakota; Clinton High School of Com- 

 merce, New York City ; Barnard College, Columbia University, and 

 the Connecticut College, in which he is now Professor of Biology. 



Dr. Osburn is known to entomologists as the author of a number 

 of papers on Syrphidae and Odonata and he was for several years 

 President of the New York Entomological Society. He is much 

 interested in the ecology of aquatic insects, but his main work has 

 been upon aquatic invertebrates and fishes. 



Adult Chrysopidae Do Eat (Neur.). 



I was very much interested in the Notes on the Feeding Habits of 

 Adult Chrysopidae, by L. Bradford Ripley, in the January, 1917, num- 

 ber of Entomological News. 



By actual observation I can indorse Prof. Ripley's statement that 

 Chrysopidae take food in the adult stage. While my observation was 

 of short duration and of a single specimen, it proved beyond a doubt 

 that these insects are far from being abstinent. On the evening of 

 September igth, 1916, an adult Lace-winged fly was captured and the 

 next morning, having just finished eating a juicy pear, I had occasion 

 to examine this specimen which was in a stupid condition, as I now 

 believe for the want of food. 



No sooner had I taken it into my hand than it began to gnaw at my 

 fingers, which were yet moist with the juice of the pear. Taking a tip 

 from this, I sprinkled some granulated sugar on my hand which it 

 ravenously ate. 



Through a hand-glass we saw grain after grain quickly disappear, 

 and this little creature did not content itself to feed among the scatter- 

 ing grains, but waded into the thick of the sugar. This specimen was 

 placed back in the jar with some sugar and water where it remained 

 until the next morning when I took it from the jar to feed it some 

 more pear juice. 



When placing it on my hand, as I had the day before, I found to 

 my disappointment that I did not have the little pet that I thought I 

 had, for it briskly flew away, showing that the gentleness of the day 

 before was caused by hunger. After finding that these insects feed 

 on sugar and fruit juice I have but little doubt about their feeding on 

 the natural sweets of flowers and plants. WILTON T. GOE, Portland,
