fessor and Mrs. Comstock's " Manual for the Study of 

 Insects," and Professor Grote's " Systema Lepidoptera 

 Hildesite," also a valuable work by Professor L. C. Miall 

 on the " Natural History of Aquatic Insects," containing 

 chapters on their physiology and anatomy. 



The fifth volume of the " Cambridge Natural History," 

 treating inter alia of insects by Dr. David Sharp, has also 

 recently appeared. The more popular orders of Insecta are 

 not dealt with in this volume, but to the specialist who 

 may wish to learn something of those other orders the 

 book will be valuable. 



Amongst the many interesting papers published during 

 the year, the first place for original work should, I think, 

 be given to Dr. Chapman's two papers, the one on 

 " Notes on Butterfly Pupai, with some remarks on the 

 Phylogenesis of the Rhopalocera " (" Ent. Record"), and 

 the other entitled " Notes on Pupse," in the Transac- 

 tions of the Entomological Society of London. Other 

 papers calling for particular attention are Mr. Oswald 

 Latter's notes on the " Secretion of Potassium Hydroxide 

 by Dicranura vinula, and Similar Phenomena in other 

 Lepidoptera," also published in the Transactions of the 

 Entomological Society. A paper by Mr. F. Gowland 

 Hopkins, on the " Pigments of the Pieridas," which points 

 out an actual chemical t-^.st for mimetic species of whites, 

 published in the Transactions of the Royal Society. Dr. 

 Weissmann's paper on the " Seasonal Dimorphism of Lepi- 

 doptera." Mr. Tutt's attempt to correlate the results 

 arrived at in recent papers on the Classification of Lepi- 

 doptera in the Entomological Society's Transactions ; and 

 Dr. Dixey's translation from the German " On the Cause of 

 Variation and Aberration on the Imago Stages of Butter- 

 flies," published in "The Entomologist." We have also 

 the continuation of Mr. C. G. Barrett's great work on " The 

 Lepidoptera of the British Islands," and the commencement 

 of a handbook on " British Macro-Lepidoptera" by Mr. B. 

 G. Rye ; whilst for less scientific readers we have the con- 

 tinuation of " The Royal Natural History " published by 

 Messrs. Warne, and a pocket guide to British Wild Flowers 

 by our late president, Mr. Step. 



It now only remains for me to thank you, gentlemen, 

 one and all, for the honour paid me in electing me as your 

 president, and for the unvarying consideration you have 

 exercised towards me during the past twelve months, and 

 most cordially to congratulate you on your ratification of
