of Polenta, thus needlessly criticizing Mr. Morrison and afterwards Mr. J. B. 

 Smith. But my first specimen oi P. Richii (see Bull. Buf Soc. Nat. Sci.) 

 was given to me as authentically determined, and I was confirmed in my 

 belief by seeing the type of Poleiita afterwards, which curiously resembled 

 my species, though not so brightly colored ; I, however, could not examine 

 its structure, which is now stated by Mr. Smith to be quite different from 

 my species, P. Richii, inasmuch as the anterior tibiae are said to be un- 

 armed. I hope to be able to figure our two species of Plagionmnicus ere 

 long, the genus being very interesting to me from its casual resemblance 

 to Lygranthoecia, though structurally so different. 



BOOK NOTICE. 



Systematic Review of Fossil Myriopods, Arachnoids a?id Insects : By 



Samuel H. Scudder. 



This work, separately printed in German out of the " Handbuch der 

 Palgeontologie," Leipzic, 1885, is a most welcome one to the student who 

 was obliged to look for information as to its subject in a quantity of dif- 

 ferent publications. The text is remarkably clear and concise, and wood- 

 cuts illustrating the different genera give all possible information on the 

 difficult subject. That so many existing families of insects were repre- 

 sented in the Miocene is remarkable. The beetles, owing to their hard 

 forms and sharp outlines, are the best preserved and the most recogniz- 

 able. Even a Stylops has been found in Prussian amber, which belongs 

 to a genus which may be called Mengea after its discoverer, the term 

 Triaena being used for a sub-genus of Apatela called by Guenee after- 

 wards Se?naphora, and which is not unlikely to come into use as a distinct 

 generic term. The Lepidoptera are very sparingly represented in the , 

 Tertiary, but the larger groups all existed. An interesting figure of the 

 fossil butterfly, Prodryas Persephofie Scudd., is given from the Oligocene 

 of Florissant, Colorado, where the beds have proved prolific in insect 

 remains. Even a caterpillar (Provence) has come up to us out of these 

 abysses of time. 



This brief notice of a work which will add enduringly to Mr. Scud- 



der's reputation, will be sufficient to call the attention of the readers of the 



Canadian Entomologist to its publication, and is all that is here 



designed. The book itself will repay study, and it is hoped that it will 



also appear (as it doubtless also exists) in English.
