Besides the above there is an "Index-Catalogue of Species, 

 Varieties and Aberrations," an " Index to the General Subject," an 

 "Index to the Vernacular or Common English Names," an "Index 

 to the Family, Sub-family, Tribal and Generic Names," and an 

 " Index to the Plates." 



Each British butterfly is described under the following heads : — 

 •(1) Synonymy (Generic and Specific). (2) Imago. (3) Variation 

 (with general remarks and summarised diagnoses of all described 

 forms, British and Continental). (4) Egg. (5) Larva. (6) Pupa. 

 (7) Time of appearance. (8) Habitat and Distribution. Besides 

 these, there are extended remarks on each of the Tribes, Sub-families, 

 Families, Divisions and Super-families. The descriptions of the 

 "Larvffi " and " Pupae " are largely original, and made directly from 

 the objects by the author. 



The errors in the old standard works (Newman, etc.) have been 

 •corrected, and the data which have accumulated during recent years 

 have been incorporated. This is especially the case with the life- 

 histories of the various species, a complete detailed life-history of 

 every species being given. 



At the end of each chapter is a concise summary giving the following 

 information about each species : —I. Dates for finding (1) the ovum ; 

 (2) the larva; (3) the pupa; (4) the imago. II. The method of 

 pupation. III. Food-plants. 



There is no need to have the book reviewed in any more exhaustive 

 manner in the Kecord. We can only ask that readers of the Furord 

 should give to the publishers, who are quite new to our branch of 

 work, their encouragement and support.

WORK OF destroying THE INSECT IN THE COMMONWEALTH OF MASSACHUSETTS, 

 TOGETHER WITH AN ACCOUNT OF ITS HISTORY AND HABITS, BOTH IN 



Massachusetts and Europe. [By Edward H. Forbush and Charles 

 H. Fernald, A.M., Ph.D., Boston, 1896. 1 vol., pp. 495, with 

 appendices, 66 photographic and colored plates and five maps.] — I 

 have no hesitation in saying that this work, for beauty of illustration 

 and the thoroughness with Avhich the subject is treated, is unrivalled 

 in the annals of American economic entomology. It is not possible, 

 within the brief limits of this notice, to do more than draw attention 

 to its publication, and to state that, whatever could be done to abate 

 this imported pest, has been done by Messrs. Forbush and Fernald, 

 and that in this case the right persons have been entrusted with the
