DR. FRANZ LOW. 



It is with profound regret that we have just received from his brother 

 the sad news of the death of Dr. Franz Low, which took place at Vienna, 

 Austria, November 22, after a long and painful illness. With him en- 

 tomological science loses a conscientious worker, whose labors have 

 greatly added to the common stock of knowledge, and his premature 

 death (he died in his sixty-first year) will everywhere be felt as a 

 calamity. 



His first entomological paper was published in 1857, and treats of 

 the larvse of the Coleopterous genus Nebria, but he soon became more 

 interested in the life-history of gall-producing insects, especially Diptera, 

 Homoptera, and Acarince. Of his numerous papers on this subject, 

 published mostly in tbe Proceedings of the Zool. botan. Society of 

 Vienna, every one marks an addition to our knowledge. This is es- 

 pecially true of the classification and life-history of the Psyllidce, and 

 he became the recognized leading authority on this intricate group of 

 insects. Notwithstanding the works by Flor and Thomson, the clas- 

 sification of Psyllidce had remained practically where Forster left it in 

 1848, and Low's paper, " Zur Systematik der Psylloden," published in 

 1879, marks the first genuine progress since that time. Some years 

 previously he had pointed out the great importance of the study of the 

 earlier stages of Psyllidce to a thorough understanding of this family, 

 and his numerous contributions to this subject show how indefatigable 

 he was in tracing and describing them. 



Dr. Low will also be remembered as the author of several valuable 

 papers on Myiasis, and as one of the collaborators on the Zoologiscber 

 Jahresbericht from 1883 to 1885. Personally we shall greatly miss him 

 as one of our most valued European correspondents, always ready to 

 assist with suggestions and criticisms given in the most amiable and 

 unpretentious way. He took a keen interest in American entomology ■ 

 and it was a delightful (if often difficult) task to answer the many 

 knotty questions he plied us with in his letters regarding all sorts of 

 insects, especially those treated of or described by the older authors. 



EUGENE MAILLOT. 



We also deeply regret to learn of the death of another valued friend 

 and correspondent, Maillot, director of the silk station at Montpeilier. 

 Maillot was a man of great scientific ability, and was, at the same time, 

 an eminently practical man. He was studying the different races of 

 silk-worms from all parts of the world at the time of his death, and had 

 contributed in a large measure to the general adoption in France of 

 the microscopic selection of silk-worm eggs as a preventive against 

 pebrine. He was a student of Pasteur's, and a comparatively young 

 man. His work entitled " Logons stir le ver a sole du MuHer? from a 

 tbeoretical and practical point of view, is one of the best treatises upon 

 sericulture which has been written up to the present time.
