member in many capacities for a number of years. He was also a 

 member of the New York Entomological Society and a member of the 

 Brooklyn Institute of Arts and Sciences, being President of its Depart- 

 ment of Botany and an officer of its Department of Entomology, and 

 annually delivered lectures before these departments in their respective 

 courses. For twenty years he had been a member and subsequently a 

 Fellow of the American Association for the Advancement of Science, 

 an honor conferred upon him in recognition of his scientific researches 

 and attainments, and for like reason he received from his own College 

 the degree of Doctor of Philosophy. He was one of the first mem- 

 bers of the Holland Society, tracing his descent from the Von Hoist 

 family, who at an early period settled in Brooklyn, and from whose 

 name his own was derived. 



It is unnecessary to give in detail a list of Dr. Hulst's numerous 

 contributions to botanical and entomological literature. Many of the 

 latter consist of short papers upon miscellaneous subjects, scattered 

 chiefly through the Bulletin of the Brooklyn Entomological Society, 

 published from 1878 to 1885, Entomologica Americana published from 

 18S5 to 1890, Journal New York Entomological Society, and the 

 Transactions of the American Entomological Society, in which latter 

 the majority of his descriptions of species appears. 



He worked in both macro- and micro-lepidoptera, and described 

 many species in various genera of both divisions. One of his prin- 

 cipal papers is a very complete synopsis of the genus Catocala, pub- 

 lished in the June (1884) number of the Bulletin. He also did much 

 systematic work in the Phycitida^ and Epipaschiina;, but his best efforts 

 seem to have been reserved for the Geometridte, in which family his 

 described species outnumber those of any other author. It had been 

 his ambition to place the knowledge of this intricate and troublesome 

 family upon an orderly and exact basis, and it is to be deeply regretted 

 that he was unable to realize the fruition of his hopes in the cause of 

 entomological learning. 



His collection of Geometridce was one of the best, if not the best, 

 in the country. Many of his types were deposited in the Museum of 

 the Brooklyn Institute, but his collection of lepidoptera was some 

 years ago donated and delivered to Rutgers College, Dr. Hulst only 

 retaining in his custody such portion as he required for study and 

 comparison. 



His widow, two daughters and one son survive him.
