responsible for the Malacodermata, Erofylidae, Endomychidae 

 and Coccinellidae. Another veteran who has gone from among 

 us, although he was rarely seen at our meetings, is Mr. Alfred 

 E. Hudd of Bristol, an accomplished antiquarian as well as 

 Entomologist, whose election to the Society dates from 1865. 

 By the untimely death of Mr. Frank Milburn Howlett the 

 Society has been deprived of an Entomologist of great acquire- 

 ments and even greater promise, especially in the biological 

 and physiological aspects of our Science ; and the same may 

 be said of the late Dr. Charles Gordon Hewitt, the Dominion 

 Entomologist of Canada, whose work was on closely similar 

 lines. Another serious loss is that of Prof. Leonard Doncaster, 

 F.R.S., whose researches in the field of genetics mark an era 

 in biological science ; and in particular his discovery in 1906 

 of the phenomena of sex-determination in Abraxas grossu- 

 lariata, as the result of an elaborate series of breeding experi- 

 ments, is of the greatest interest to Mendelians. The death 

 within the last few days of Dr. H. H. Corbett and Mr. J. W. 

 Carter, deprives Yorkshire of two of its most prominent 

 Entomological workers; two well-known Dipterists have 

 passed away in the Marchese Piero Bargagli and Mr. Frederick 

 C. Adams ; and Australia has lost her premier Arachnologist in 

 Mr. William J. Rainbow, the Entomologist to the Australian 

 Museum, Sydney, whose death took place in November 1919. 

 To these may be added the names of Commander the Hon. 

 Richard O'B. Bridgeman, R.N., F. M. Campbell, and James 

 T. McDougall, respecting whom, however, I have no particu- 

 lars ; nor must we omit the names of Frederick Herschel 

 Waterhouse,' the last survivor of a family of distinguished 

 Entomologists, and of William West, known to most of us 

 as a frequent visitor and exhibitor at our meetings for many 

 years past, although neither was a Fellow of the Society. 



I now proceed to the Entomological essay which custom 

 requires of the President on these annual occasions. 



Some Aspects of Insect Life in New Zealand. 



The choice of the subject of my Address has been deter- 

 mined by two considerations. First of all, nearly twenty
