and Acanthococcus aceris, Sign. ; Description of two new species, Pulvinaria erica-, 

 Low, and Boisduvalia picece, Low. There are also papers on Coccidm in the 

 <' Verhandlungen : " — On Diaspis visci, Schra.vi's. (with a phxte) ; On a new genus 

 and species, Xy lo coccus filifer us. Low (with a plate), a wonderful creature that lives 

 in the small branches of Tilia grandifolia ; and On the scale of the Dianpida. 

 Aphides had some attention from him, for in the "Verhandlungen," 1877, he had an 

 article on Pemphigus zea maidis, Linn., and in the " Ent. Zeit.," vol. i, ia a description 

 of Pemphigus nidijicus, Low, n. sp. He also studied Cecidomyiidce, &c. {Diptera), 

 and contributed articles thereon to the " Verhandlungen." And in some of the 

 volumes of the " Zoologischer Jahresbericht " of the Zoological Station at Naples, 

 are Reports on Herniptera made by Dr. Low and his brother Paul, as referees. 

 Probably some of his work is here casually overlooked. 



The loss of such a man in the prime of life and in the plentitude of his labours 

 is very sad. We lament for him not only as an effective scientific worker in a field 

 in which he held the foremost place, but also as a friend ever eagerly willing to place 

 his accumulated knowledge at our service, and now prematurely departed. — J. W. D. 



J. B. Oehin, a French entomologist, died at Eemiremont on the 2nd December, 

 1889, aged 73. He published much on the genus Carahus and its allies. Some of 

 his work did not escape severe criticism. He formed a wonderfully rich collection 

 of the gi'oups he specially attended to, which we understand was purchased, a few 

 months before his decease, by M. Rene Oberthiir, and will augment his collection at 

 Rennes. 



Prof. William Ramsay 3Ii-Nah, 31. D., F.L.S., died very suddenly at Dublin, 

 from heart disease, on December 3rd, at the early age of 45. His grandfather and 

 father were successively curators of the Botanic Gardens at Edinburgh. Educated 

 for the medical profession he took his degree at Edinburgh in 18G6, and for a time 

 held an official medical appointment. But the hereditary instinct for Botany seemed 

 to have prevailed. He became Professor of Natural Histoi'y at the Royal Agricul- 

 tui'al College at Cirencester, and subsequently of Botany at the College of Science 

 at Dublin, and was also (at the time of his death) scientific director of the Royal 

 Botanic Gardens at Glasnevin. He published several useful works on physiolosical 

 and fossil botany, and was greatly esteemed in Dublin amongst the students, and his 

 colleagues at the Royal College of Science. His name occurs frequently in the early 

 volumes of this Magazine in connection with Scottish Coleoptera. His constant 

 friend and fellow-student. Dr. Sharp, informs us that the entomological proclivity 

 was probably derived from an uncle. Dr. Gilbert McNab, an Ayrshire man, who had 

 a collection of insects, and wlio was the authority for several species recorded in the 

 late Andrew Murray's Catalogue of Scottish Coleoptera, and this led to his making 

 the acquaintance of Andrew Murray himself. Dr. Sharp adds that his first intro- 

 duction to McNab was at a lecture on pathology at Edinburgh, when the perusal of 

 an early No. of this Magazine acted as a stimulant and kept at least two of the 

 audience awake. About 1870 he married a daughter of the Rev. Dr. Goold, of 

 Dumfries, whose wife, tide Crawford, was first cousin to one of our editors. The 

 widow and five children deplore his loss.
