This gigantic work is of an eminent importance and will be a quite 

 indispensible vademecum to every one who works on beetles, and as a 

 most valuable compendium ought to find place in every entomological 

 library. 



To all coleopterists, beginners as well as advanced scientific entomolo- 

 gists, this catalogue will be of the greatest use, saving them from the 

 trouble and loss of time that until now were necessary when searching 

 through the literature of the families, subfamilies, genera and subgenera 

 of the Coleoptera of the world. We have in this catalogue the whole 

 literature (including all synonyms, errata, etc.) on the subject, put to- 

 gether in a marvellously clear and instructive manner. Notwithstanding 

 the immense number of the citations, they can all be contained in two 

 volumes, while, thanks to a system of abbreviations, that is most agree- 

 able to the purpose, they occupy less space than in the other catalogues. 



Every Coleopterist, the advanced specialist too, will have to consult 

 this work on all questions concerning the above-named systematic groups.

10?/^ sheet. On finest woodless paper. With many figures and 3.5 big 



plates, 13 of them colored. 



Price go Mark. 



The favorite of all collectors of European butterflies, Parnassius Apollo 

 and its nearest allies, interesting to collectors by its beauty, variability 

 and biology, is treated in this work by the best connoisseur of this genus 

 and three other well-known entomologists. The plates are first rate by 

 their natural reproduction and by their artistic e.xecution. The text is 

 printed on the best woodless paper and got up in a splendid style with 

 many figures. 



All these qualities will secure for the work a standard place in lepidop- 

 terological literature. 



On both prices must be added the legal foreign procentual tax (at the 

 moment 175%.)
