In summing up the author says "We have now carried on a sufficient 

 number of experiments with both mulberry and eri silkworms in the 

 Philippines to warrant the statement that this industry can be carried 

 on here under conditions as favorable as those which obtain in the 

 best silk producing countries of the world and with the added advan- 

 tage that no disease has appeared among the insects, or on the trees 

 used for feeding them." The work is a very useful one and will 

 doubtless stimulate an interest in the subject. H. S. 



THE EUPI^EXOPTERA AND ORTHOPTERA OF CONNECTICUT. By Benjamin 

 Hovey Walden. Bull. No. 16, Connecticut State Geol. & Nat. 

 Hist. Survey, Guide to the Insects of Connecticut, pt. II, pp. 41- 

 169, Pis. VI-XI, 63 text figures. 1911. 



The author of the above paper and the editor of the Guide to the 

 Insects of Connecticut, Dr. W. E. Britton, are to be congratulated 

 on the appearance of this very interesting and useful work. In an 

 introduction of three pages the author reviews previous work which 

 had been done on the Connecticut Orthopterous fauna, as well as giv- 

 ing such acknowledgements and abbreviations of collectors' initials as 

 are necessary. The systematic treatment is comprehensive, with keys 

 to the genera and species and diagnoses for each, while the distribu- 

 tion within the state is summarized in the more generally distributed 

 forms and the localities indicated in the scarcer and more localized 

 forms. The arrangement is in accordance with Scudder's 1900 Cata- 

 logue, while the keys of genera and species are chiefly from Morse 

 and Blatchley. 



The numerous text figures, a portion of which are original, assist 

 very greatly in a clear understanding of the text, making the work 

 of value to the specialist as well as to the local student. 



The number of species treated is one hundred and nine, of which 

 one hundred have been recorded from the state, the remaining nine 

 being included on the probability of their occurrence within the state. 



From the nomenclatural standpoint the names are not in all cases 

 those used by most authors at this date, i.e., Tettix instead of Acry- 

 dium, Stenoboihrus instead of Chortlrippus, Locustidae instead of 

 Tettigonidac, and Xabea instead of Neoxabea, but this is probably due 

 to a close adherence to Scudder's Catalogue, although other recent 

 changes, as Blattella for Pliyllodroinia, have been made. 



The general character of the work is excellent and it will stand with 

 Blatchley's Orthoptera of Indiana as the best type of a state cata- 

 logue of insects, more of which we hope will be forthcoming in the 

 future. 



The only suggestion we can make for the authors of such works 

 in the future, and one based on considerable experience in mapping 

 the distribution of Orthoptera, is that enough localities be cited for
