Brunner von Wattenwyl has improved the 

 opportunity offered by the study of the large 

 series of Orthoptera collected by Fea in Bur- 

 man, to attempt a general revision of the 

 system of Orthoptera by the introduction of 

 tables for the determination of all the known 

 genera (occasionally groups of genera) in 

 the order, excepting only such as have been 

 recently so treated elsewhere, when due 

 reference is made. It will be found exceed- 

 ingly useful for systematists, for no such 

 general work has appeared since the time of 

 Burmeister and Serville. A considerable 

 number of new genera are thus introduced, 

 and among them not a few of North 

 American forms based sometimes on des- 

 cribed, occasionally on undescribed species. 

 The addition of at least a brief diagnosis of 

 such species would have been acceptable. 

 The work forms the first part of v. 33 of the 

 Annali del museo civico di Genova. 



L. Bruner prints a list of Nebraska 

 Orthoptera reaching the astonishing number 

 of 268 distinct kinds, a testimony to the 

 activity and zeal of the author as well as to 

 the extreme fruitfulness of his field. Brief 

 notes of habitat and abundance accompany 

 each entry (Publ. Nebr. acad. sc, 3). 



C. H. Tyler Townsend has left his posi- 

 tion as entomologist in the experiment 

 station at Las Cruces, New Mexico, to accept 

 the curatorship of the museum in the Insti- 

 tute of Jamaica at Kingston, W. I., formerly 

 occupied by Mr. Theodore D. A. Cockerell, 

 who, curiously enough, moves to Las Cruces 

 to take Mr. Townsend's place. 



The Brussels Museum has begun the pub- 

 lication of a general catalogue of Hemiptera 

 by Lethierry and Severin on the plan of 

 Gemminger and Harold's catalogue of 

 Coleoptera. The first volume embracing 

 the Pentatomidae is promised at an early day. 

 The whole work will probably occupy nine 

 volumes and require five or six years for its 

 publication. Its price will be about one cent 

 a page. 



Two new books on butterflies, by S. H. 

 Scudder, have just been published by Henry 



Holt & Co., of New York. One is a guide 

 to our common butterflies and describes 

 eighty-four species including (with only half 

 a dozen exceptions) the caterpillar and 

 chrysalis as well as the butterfly of each, 

 besides tables to determine them in everv 

 stage. Brief biographies of each species are 

 given and at the beginning there is a general 

 introduction to the study of butterflies. The 

 other is a very full account of the life of 

 a butterfly for general readers, our milk-weed 

 butterfly being the central figure. 



The Western university of Pennsylvania 

 has just conferred the degree of D. Sc. on 

 Frederick Moore and of Ph. D. on A. G. 

 Butler, both of London, in recognition of 

 their work in entomology.
