"The collecting work was highly successful, and as a result of the trip 

 15,000 specimens, all pinned and labelled, have been brought back. Of 

 these many are species hitherto unknown. ' I should estimate that we 

 have secured at least 50 to 100 species new to science,' Dr. Snow said 

 when questioned on this point. 



"The collection includes specimens from all the Orders. The tabula- 

 ted list of the specimens secured is as follows : Coleoptera, beetles, 5 430 ; 

 Diptera, flies, 4,500; Lepidoptera, butterflies and moths, 1.926; Hymen- 

 optera. bees and wasps, 1,822; Orthoptera, grasshoppers and crickets, 

 550; Hemiptera, bugs, 232; Neuroptera, dragon flies, 169; a total of 



14,629."

THE ORTHOPTERA OF INDIANA. Bv W. S. BLATCHLEY. From the 2yth 

 Annual Report of the Department of Geology and Natural Re- 

 sources of Indiana, 1902, pp. 125-471, Author's Separates issued 

 September 5, 1903, Indianapolis. 



In presenting this work to the entomological world, Prof. Blatchley has 

 supplied us with a model for future work along faunistic or state lines. 

 A glance at the map on page 126 will show how thoioughly the state has 

 been examined by the author, and a perusal of the systematic portion of 

 the work will demonstrate how amply he has been rewarded in the ex- 

 tension of the range of many species, and the discovery of quite a few 

 new forms. 



After a good preliminary chapter on the external structure of an Ortho- 

 pterous type, the enemies of the order are treated at some length, and a 

 rather exhaustive bibliography comprising two hundred and twenty- 

 three titles precedes the descriptive catalogue. 



The systematic portion of the work contains references to one hun- 

 dred and forty-eight species, each of which is well described, and the 

 life-history and period of abundance, as well as the distribution (both 

 general and within the state) considered. The illustrations are good, the 

 originals being especially interesting as many represent species never be- 

 fore figured. In all seven new species arc described : Ischnoptera intri- 

 cata, NeotettLv haucocki, Melcuwplus inorsei, Conocephalus bruneri, Ne- 

 iiiobins confitsus, Gryllus auiericanus&nd G. arenaceiis. Under the Forfi- 

 culidse no reference is made to Bormans and Krauss' recent work on that 

 family, and in consequence Forficiila aculeata is not placed in ,//>/<; -];;/</<?. 

 In working out, as far as his material permitted, the relationship of the 

 species of roaches of the genus Ischnoptera and some of those usually 

 placed under Tcnuiopteryx and Phyllodrouiia, the author has given us 

 by far the most thorough and pains-taking piesentation of this knotty 

 problem of sex correlation. The re-discovery of Tcnniopteryv dcrop- 

 eltiformis is a most interesting find, and is especially noteworthy, as 

 both sexes have been secured.
