West Indies Maxwell-Lefroy briefly served as assistant master at Seaford College, and then joined as an entomologist in Barbados from 1899. Before he left Barbados he got engaged to Kathleen Hamilton O'Meara, daughter of a former Provost Marshal in British Guiana from a Catholic family, leading to some disapproval from his mother and sister. His entomological work resulted in several bulletins being published. India In 1903, Maxwell-Lefroy was appointed entomologist to the Government of India (succeeding Lionel de Nicéville, who was the first entomologist, appointed in 1901). The appointment may have been influenced by David Sharp. His salary in India was set at 750 rupees a month rising 50 a year to a maximum of 1000 a month. He sailed by the P&O steamer Borneo on 27 March and reached Bombay on 30 April 1903. He was then sent to Calcutta where he was to report to E.P. Stebbing. He married Kathleen on 22 January 1904 in a Catholic wedding at the Cathedral of the Holy Name, Bombay. In 1904, Maxwell-Lefroy was assisted by K. P. Ukkendan Unni Nair, a zoologist trained at the Madras Christian College. Several Indian assistants worked with him including S.C. Misra from Nagpur who had worked at Rajkumar College, C.C. Ghosh from Calcutta University who was in-charge of the Pusa insectary, Gobindram Dutt from Punjab and D. Nowroji from Madras University. In 1905 he was involved in the establishment of the Imperial Agricultural Research Institute in Pusa, in the Indian state of Bihar, and was appointed the first Imperial Entomologist. He was assisted by F.M. Howlett who was appointed the Second Imperial Entomologist . Although mainly involved in work on agricultural pests, he also took an interest in medical and veterinary entomology. In 1907 he oversaw studies to examine whether there was a possibility for Indian insects to spread sleeping sickness brought in by Indian workers returning from Africa. In October 1908 he accepted permanent employment with the Government of India. Maxwell-Lefroy convened a series of meetings on an all-India basis, to bring together all the entomologists of the country. From 1915, five such meetings were held at the Imperial Agricultural Research Institute, and these formed the foundation of entomological knowledge in India. He was succeeded in the position of Imperial Entomologist by T. Bainbrigge Fletcher. Maxwell-Lefroy's approaches to agricultural pest management was principally aimed at being practical and low-cost, often advocating cultural practices such
