mologists must look back with gratitude to bis kindness and assist- 

 ance. "Tbe World of Insects, a Guide to its Wonders," was 

 published in 1850, and he rendered very important assistance in the 

 production of Stainton's " Natural History of the Tineina," in which 

 his name appears as a coadjutor. Another, and perhaps the work 

 by which his name will be best remembered, was published by the 

 Ray Society in 1865, "The British Hemiptera, Vol I, Hemiptera- 

 Heteroptera.'" In this he was a joint author with the late John 

 Scott. It opened the eyes of British Entomologists to the large field 

 of little known forms which existed in this interesting Order, and 

 Douglas and Scott's "British Hemiptera" will always be regarded as 

 a classical work in this country. At the time it was written the 

 Hemiptern of Britain were practically unworked, and all flntomo- 

 logists owe a great debt of gratitude to the Authors of the " British 

 Hemiptera " for the excellent foundation which they laid, and also to 

 Dr. Fieber, of Vienna, for the assistance he rendered in determining 

 many of the unknown species. Additions and corrections to this 

 book were from time to time published in the Entomologist's Monthl}"- 

 Magazine, of which he became an Editor in 1874, and to which for 

 many years he was a constant contributor. In the early days of the 

 Entomological Society he was a very active member. He joined the 

 Society in 1845, became a Member of the Council in 1846, Secretary 

 from 1849 to 1856, and President in 1801. He retired from the Society 

 in 1802, but rejoined it in 1870, continuing as a Fellow to his death. 

 The writer of this will always have an affectionate memory of the kind- 

 ness of the deceased to himself ; he often had occasion to consult 

 him on questions connected with the determination of specimens, and 

 alw^ays met with the greatest kindness. On one occasion he borrowed 

 the type specimen of a Capsid, the identity of which he had called in 

 question, and whilst in his possession, one of his children finding a 

 nice looking little box, put some pens into it and shook them up, with 

 the natural result that the specimen was broken to atoms. Any one 

 can imagine the writer's feelings when he had to go and confess what 

 had happened ; but the situation was accepted in the kindest way, 

 and without a touch of reproach. For the particulars of the early 

 life of the deceased we are indebted to his son, Mr. Charles D. 

 Douglas. 



It is many years since J. W. Douglas took an active part in 

 Entomology, and many of the younger Entomologists of to-day may 

 hardly realize how much he did for their Science ; but those who 

 knew him feel that another link with the past, and an important one, 

 has been broken. — E. S.
