 family. 



The name Petropteron is in allusion to the Pierre formation.

BOOK NOTICE. 



Contributions to the Natural History of the Lepidoptera of 

 North America, by Dr. William Barnes and Dr. J. H. McDannough, 

 Decatur, III. 



Under the above title have appeared the first two parts of a new and 

 much needed work on the Lepidoptera of North America which will meet 

 with the heartiest commendations from all corners of the continent. 



Prior to the publication by Dr. Holland of "The Butterfly Book" 

 and "The Moth Book," there were but {t'^ entomologists who could 

 afford to possess, or were fortunate enough to have access to, the rare and 

 expensive separate works and long sets of volumes of periodicals in which 

 to look for figures and descriptions. These two books, and particularly 

 the plates, for the text is of necessity very limited, have proved of the 

 greatest help to beginners and the more advanced as well, and many. of 

 us ventured to hope that the time might soon come when a reliable figure 

 of every known North American species would be available. Now after 

 a wait of eight years, our expectations begin to be realized, as the " Con- 

 tributions" are exactly what we most needed, namely, a series of mono- 

 graphic reviews of families or smaller groups, giving descriptions of all the 

 species, references to the more important literature, placing the generic 

 names on a more stable basis, and last, but not least, photographic figures 

 of each and every species. 



Part I deals with "The Cossidae of North America" and consists of 35 

 pages of text and seven plates (three -of structure and four of imagos) and 

 an index. Part II is entitled "The Lasiocampid Genus Gloveria and Its 

 Allies" — 17 pages of text, one plate of venation and three plates of imagos 

 and an index, and covers a little wider range of territory, species from 

 Mexico and Central America being included. 



The size of page conforms with Dr. Holland's books, the text is well 

 printed on excellent paper and the illustrations are all on plate paper. 

 Much care has evidently been taken to secure accurate reproductions ?.nd
