Mr. Bruner on Insects injurious to young Trees on Tree Claims.* — We have 

 just referred to the report by Mr. Bruner upon this subject in Bulletin 

 No. 22 of this Division, and now call attention to his more elaborate 

 l^aper, which covers 150 pages of the Nebraska Station Bulletin. The 

 accounts of the species are in the main compiled, but a few original 

 notes are added ; 98 figures are introduced, most of which have been 

 published before. The drawing together of these accounts is very ap- 

 propriate to the subject in hand, and the bulletin makes a handy book 

 of reference for the tree-grower in the arid regions of the west. The 

 appendix includes a consideration of remedies. 



Catalogue of the Spiders of temperate North America. t — When the study 

 of any branch of zoology has progressed sufficiently to permit so exten- 

 sive and careful a list as that prepared by Dr. Marx of the spiders of 

 America north of Mexico, our knowledge thereof may be said to be placed 

 upon a basis from which i^rogress is comparatively easy. The extent of 

 the catalogue surprises us, including, as it does, about a thousand species. 

 It is more than a catalogue, as all of the synonyms of families, genera, 

 and species have been worked out by Dr. Marx, and are published with 

 fall bibliographic references. An index to families and genera, to syn- 

 onyms of genera and a separate bibliography as well as a series of notes 

 add greatly to the working value of the catalogue. We anticipate that 

 the ijublication of this work will greatly increase the number of stu- 

 dents of spiders and regret only that it was not prefaced with a few 

 practical hints as to collecting and preserving. 



Vesicatory Insects — We have just received from the author, Prof. H. 

 Beauregard, his monograph of the vesicatory insects.| For ten years 

 Professor Beauregard has been at work upon this subject and has given 

 us a monograph which exhibits the greatest ability and industry. He 

 has taken up in succession the following phases of his subject : Part I, 

 concerns the anatomy of these insects; Part II, the physiology and 

 pharmacology. In this second part he especially treats of the place 

 which the Cautharides hold among insects and of the comparative ves- 

 icating power of a large number of species of many genera. Part III 

 is devoted to the habits of the different forms and to the study of their
