reliable infonimiion, bearing on the work of the lepidopterist in the field, telling him 

 exactly what to do and how to do it in the fewest possible words, and in the least possible 

 space. Such information could only be gathered by the individual worker as the result of 

 many years' observation and by reference to many books in which the facts are buried 

 amongst a mass of other entomological detail. Lepidopterists, experienced and inex- 

 perienced, will tind in this book much information that will suggest quite new lines of 

 work in their collecting, and enable them to find, in close proximity to their homes, 

 species which they had never suspected to be in their vicinity, and the saving of time and 

 trouble will thus be enormous. As the method of work in the field was more particularly 

 dealt with in I'art I, the summaries in Part II deal more especially with the points raised 

 by the various methods of — Rearing larva) in confinement. Sleeving, Breeding-cages, Food 

 and Feeding larvie ; Obtaining eggs in confinement from butterflies and moths ; Special 

 treatment of pupii; ; Keeping pupae through winter ; Special treatment of certain larvae in 

 order to obtain pupas ; Sugaring ; Assembling ; Forcing, and a host of shnilar important 

 topics to the entomologist. Quite new ground has been broken, and there is no repetition. 

 The hints have been arranged on a precisely similar manner to those in Part I, with 

 general notes for the month at the commencement of each chapter.
