Chapman it would be difficult to find. His object invariably was to try to 

 solve some problem concerning the oviposition or life-history (particularly with 

 regard to Lycaen id-larvae living with ants) of certain Lepidoptera. Accord- 

 ingly, some particular species would be selected for investigation each year — 

 often a Lycaenid, au Erebia, a Tortricid, or a Psychid — and a journey made to 

 places where such insects were known to occur. When this work was acc'im- 

 plished, and he seldom failed to elucidate new facts, the insects bred or studied, 

 uo longer required, were presented by him to his friends. Therefore, at liis 

 death, he possessed no collection in the ordinary sens3 of the word. 



Amongst his most important contributions to science, are the life-histories 

 of various butterflies — Callophrys act's, Albulina pheretes, Agviades thersites 

 and escheri, PoUjommatus eras, Lycaena arion (concluding portion), and Scoli- 

 tantides orion (Trans. Ent. Soc. London, 1910-1915). In Vols, iii, iv, and 

 vi of this Magaxine (18G6-1870) there are papers by his father and by himself. 

 One of these articles by the son, the first written by him so far as we are aware 

 (iii, p. 94, 1866), was on the habits and oviposition of a Dipteron, Atherix 

 ibis ; and the last, entitled *' Notes on some sawflies, chiefly as to oviposition," 

 appeared in January 1922 {op. cit. Iviii, pp. 8-16), the proofs of this paper 

 having been actually ready for him at the time of his decease. His contribu- 

 tions to entomology extend, therefore, over a period of 56 years. Those written 

 at Abergavenny and Hereford concerned British insects — Diptera, Coleoptera, 

 Hymenoptera, and Lepidoptera. Seven of the earlier papers, all of which were 

 published in this Magazine, 1868-1891, are of particular value: (1) Habits 

 and transformations of /iy^smMS creuatus,frfi.vini, and vittaf,us ; (2) Aphodius 

 iwrcus, a cuckoo parasite of Geotinipes stercorarius ; (-J) Oeconomy of the 

 British species of Scolylus [less ra/zebur(/i], (4) of the Chrysides parasitic on 

 Odi/tisrus spinipes, (5) of Abdera bifasciata, and (6) of Bomhylius ; (7) Oviposi- 

 tion of 3fetoecus. The remainder are to be found in one or other of oui* 

 entomological journals, or in the "Transactions of the Entomological Society 

 of London." 



This Society owes much to his generosit}', as he contributed largely 

 towards the cost of the great number of illustrations accompanying his 

 papers. He was always ready, too, to help entomologists, and on more than 

 one occasion he entertained the numerous members of one or two of the local 

 London entomological societies at his IJeigate home. 



Chapman was elected a Fellow of the Entomological Society in 1891, 

 serving many times as Vice-President, though he could never be induced to 

 taccept the office of President, much to the regret of his friends ; a Fellow of the 

 Zoological Society in 1897 ; and a Fellow of the Royal Society in 1918. 



His funeral took place at Reigate Cemetery on December 21st, 1921. 



Tha void left in the ranks of our philosophical Entomologists by tlie death 

 of Dr. Chapman is indeed one which may not be adequately tilled for a long 

 time to come. He was never married, his last years at Reigate being passed 

 with two unmarried sisters, to whom we tender our sincere condolence and 

 sympathy in the loss of their greatly esteemed and respected brother. The 

 photograph hei'e reproduced was taken in 1905. — G. C. C,
