THE CANADIAN ENTOMOLOGIST 33 



Lord Walsingham has surely won the thanks of all students 

 of micro-lepidoptera, and especially of those on this side of the 

 Atlantic, for his great and helpful contribution.

Check List of the Hemiptera (Excepting the Aphidid^, 

 Aleurodid^ and Coccid^) of America, North of Mexico. 

 By Edward P. Van Duzee. N. Y., New YorkEntomclogical 

 Society, 1916. 



All Hemipterists will welcome the appearance of Dr. Van 

 Duzee's Check List of North American Hemiptera, as it gives 

 them, at last, a complete list of the species of this order (with the 

 exception of the three families mentioned) found within the territory 

 indicated in the title, and includes their systematic arrangement, 

 full synonymy, the date of each name and roughly the distribution 

 of each species. 



Dr. Van Duzee has followed the lines of the Oshanin Katalog 

 of Pala^arctic Hemiptera, and has included the results of the latest 

 and best systematic studies dealing with this order. The list 

 begins with the family Scutellerida? and follows, in re\erse order, 

 the system published by Renter. 



The rule of priority has been followed throughout the work, 

 and the synonymy includes that of all the higher group names as 

 well as that of the genera and species. Dififerent types are used for 

 the various grades of group names, the generic and specific ap- 

 pearing in bold-faced type, and the synonyms in italics. 



The list gives the names of 698 genera and 2,945 species, and 

 concludes with an index to the generic and higher group names, a 

 feature which greatly facilitates its use. 



Dr. Van Duzee is to be highly cxDngratulated on the completion 

 of his invaluable work, and students of Hemiptera and of general 

 and applied entomology will all feel deeply indebted to him and 

 will await with great interest the appearance of the fuller and more 

 complete bibliographical and synonymical catalogue of the Hemip- 

 tera, which will be published in the near future.
