94 THE ENTOMOLOGIST. 



and their metamorphoses, phj'siology, and " action nocive " are 

 fully treated of; the nosograpliy, etiology, diagnosis, prognosis, and 

 treatment of the various parasitic diseases — in fact their special 

 pathology is also fully set forth. The crustacean parasites of our 

 marine animals are less exhaustively handled in the concluding 

 sixteen pages, 



Many pieces of information we should like to cull from this 

 book, and we are sure they would be interesting and instructive 

 to our readers ; but, as we have said, it should be consulted by a 

 variety of workers ; as far as present information goes it will not 

 be found wanting. Its value is greatly increased by the illus- 

 trations. There are sixty-three woodcuts, very nearly all from the 

 author's beautiful drawings, and twenty- six plates, also drawn and 

 lithographed by himself. We must, however, protest against the 

 continental — especially French — method of publishing the plates 

 and text in separate parts and wrappers ; in the present instance 

 the plates are nearly half an inch each way larger than the letter- 

 press, which is demy octavo, so that it is quite impossible that the 

 volume can be bound. The price of the work complete is about 

 seventeen shillings. — E. A. F. 



Biologic der Kdfer Europas. By Mathias Rupertsberger. 

 Linz a. d. Donau. 1880. 

 Entomological literature is now becoming so voluminous, and 

 is so scattered, that judicious and concise cataloguing is one of 

 the best works that can be performed in the interest of the work- 

 ing naturalist. Herr Rupertsberger has just completed such 

 a guide in his ' Biologic der Kafer Europas.' This is an unpre- 

 tentious volume of but just over 300 demy 8vo pages, but it will prove 

 one of the greatest value to the working coleopterist, and more 

 especially to the general field naturalist. When an insect belong- 

 ing to any order is bred by the general entomologist, much 

 valuable information is often lost to science from the mere fact of 

 the great difficulty of ascertaining whether the observations made 

 have been previously recorded. This remark is especially 

 applicable to the Coleoptera, about whose economy so little 

 is known in this countr}^ ; many species are met with in the 

 larval state and their life -history noted, but the uncertainty 

 of whether the observations are new or not delays publication. 

 Rupertsberger's valuable compilation will at once refer us to our
