CocKERELL, T. D. A. Names Applied to Bees of the Genus Osmia, found in 

 North America: Proc. U. S. N. M., Vol. 42, pp. 215-225; separates published 

 April 13, 1912. In this list 167 names are given, 60 of which are represented by 

 specimens in the collections of the U. S. N. M. ; of these 60, 22 are types or para- 

 types. In each case the type, locality, and collector of the type is given, if known. 

 Many brief descriptive notes are also given. This paper will be a useful one. 



CocKERELL, T. D. A. Names Applied to the Eucerine Bees of North America : 

 Proc. U. S. N. M., Vol. 43, pp. 261-273 ; separates published Oct. 19, 1912. The 

 previous catalogue of the North American Eucerines appeared in the Transactions 

 of the American Entomological Society, Vol. 32, 1906. Since, numerous species 

 have been added and a few changes in nomenclature made. The present list gives 

 the type localities, and names of collectors of the types when known. There are 

 also references to the principal synoptic tables. Students of the Hymenoptera will 

 welcome this new catalogue.

 and Their Near Eelatives, The Scorpions, Pseudoscorpions, Whipscorpions, Har- 

 vestmen, and Other Members of the Class Arachnida, found in America North of 

 Mexico, with Analytical Keys for their Classification and Popular Accounts of 

 their Habits: New York; Doubleday, Page and Co., 1912, pp. xv. + 707, 771 figs.; 

 price $4.00. This companion book to The Butterfly Book, The Moth Book, The 

 Insect Book, and the other extremely useful nature books published by the above 

 firm will be eagerly welcomed hy entomologists. The systematic descriptions of the 

 genera and species, and particularly the keys for their identification are specially 

 valuable. The illustrations throughout the book are excellent. Now that such a 

 reliable volume is obtainable we hope to see a much wider interest taken, in Canada, 

 in these interesting creatures. To the author we extend our best congratulations 

 on the completion, in such a beautiful form of his years of work on spiders.
