REVIEWS 



The Entomologist, December 191 1. — ". . . It is only justice to Dr Seitz and his 

 numerous collaborators to emphasise the fact that they are providing much more 

 than the ' illustrated catalogue ' which was somewhat slightingly spoken of when 

 the work was first announced a few years ago. Brief descriptions of the earlier 

 stages are included wherever these are known, and the dry descriptive matter is often 

 enlivened by notes on the habits of the imago. Scientifically, too, the names of such 

 contributors as Jordan, Aurivillius, and others are guarantee that we have work of 

 real classificatory value, and their synopses and differentiations should be a real help 

 to advanced students. 



"The illustrations are for the most part good, and of practical use for the determina- 

 tion of species. We wish the enterprise continued success." 



The Entomologist's Monthly Magazine, November 191 1. — "The completion 

 of the first volume, not only in the German, but also in the English edition, and the 

 progress which is being made with various other sections of the work, afford good 

 evidence that both editor and publisher, together with the many other collabora- 

 tors, are taking their gigantic task in earnest, and that the present generation of 

 Lepidopterists may look forward to the possession, at no very distant date, of what 

 has never before been possible of attainment — a complete iconograph) of the known 

 Macrolepidoptcra^ together with letterpress adequate for the determination of 

 species, and often even further information as to their habits and the outlines of I* 

 their life-history. We are now assured that all the principal families are in the 

 hands of competent specialists, the preparation of those which are not already ' 

 actually in progress well advanced, and material accessible for figuring from the 

 richest collections. 



" The general arrangement, indexing, etc., are good; the illustrations excellent, 

 and marvels of cheapness ; and the work is worthy of the support of all who are 

 interested in the Lepidoptera^ or desirous of the wider diffusion of knowledge con- 

 cerning them." 



The Entomologist's Record, December 191 1. — "Students of the PaUcarctic 

 Butterflies must rejoice to have all the species and a very large percentage of the 

 known forms illustrated, and well illustrated, within the covers of a single volume. 

 It is the first time it has ever been done on such a scale. 



"Various collaborators have undertaken the work in the different families and 

 genera, and we get practically a short digest of the results arrived at. which in the 

 case of the more recently thoroughly worked out groups is of very great use and 

 interest. 



" In conclusion, one must mention the name of Dr Jordan, the man who was re- 

 sponsible for the translation of the original German into English. Let us say at 

 once that this is highly commendable, with far fewer slips than is usual in a trans- 

 lation of these dimensions. We offer our congratulations to Dr Seitz and his 

 numerous helpers, and hope that we shall not have to wait so long for the other 

 volumes to be completed." — W. J. K
