in which I intend to publish illustrations, with descriptive text, of pre- 

 viously unfigured species from my collection." Hypolyccsna feslatUy 

 Lenionias Maxinicz, Pyrgus pelagica, Myscelia Strcckeri, Colias hecate 

 and Prola patidora $ are figured in a most beautiful manner, both sides 

 of the insects being shown. Mr. Weeks is to be congratulated on the 

 appearance of this excellent contribution to the literature of the Lepidop- 

 tera. We shall look forward with pleasure to the appearance of further 

 contributions of a like character. — H. Skinner. 



Our knowledge of the geographical distribution of the North American 

 Odonata grows steadily. A considerable addition to the data furnished 

 by Dr. Scudder and Mrs. Slosson for New Hampshire is Mr. Edward J, 

 Biiriihain's " Preliminary Catalogue of the Anisoptera in the vicinity of 

 Manchester, N. H," published in 130, enumerating 28 species of this 

 suborder, with notes on their habits, etc. It appears that Macromia 

 illinoensh, which occurs in hundreds in a particular station near Man- 

 chester, is preyed upon by birds to such an extent that, after the 

 slaughter, the "careful observer will discover wings in vast numbers 

 scattered beneath the trees." One male each of Neiirocordulia obsoleta 

 and of Patitala flarescens are recorded ; this is the most northern lo- 

 cality in the eastern United States now known for this latter, cosmopoli- 

 tan species. 



A more extensive work is Mr. E. B. Williamson's " The Dragonflies 

 of Indiana." (24th Annual Report of the Department of Geology and 

 Natural Resources of Indiana, pp. 229-333, 1003-1011, 7 plates, Indian- 

 apolis, 1900.) This fills the same place for Indiana that Prof Kellicott 

 and Mr. Hine's "Odonata of Ohio" does for that State. Descriptions 

 of 84 species, positively known to have been found, and of others 

 likely to occur, are given, with many data on habits, place and time of 

 appearance of the imagos. A key to all the known genera, pp. 247-251, 

 and keys to "the species under each genus facilitate identification. Pp. 

 223-244 contain a general account of these insects. A feature of the 

 present work, not often met with, is the addition of the etymology of the 

 generic and specific names. A good glossary and index occupy pp. 

 1003-1010. Mr. Williamson has collected much in the vicinity of Bluffton 

 and elsewhere, while the other chief sources of the material have been 

 Mr. R. J. Weith of Elkhart, Mr. C. C. Deam and Mr. W. S. Blatchley, 

 Orthopterist and State Geologist. As regards the species represented 

 we may note a new Enallagtua, piscinarimn, allied \.o geniinatuni Kell.; 

 the identification of the long lost Agrion ajitennaia Say as Enal. Fischeri 

 Kell., the species being now consequently known as E. antennatum, 

 while in the genus Gomphus we may take this opportunity of making a 

 correction aflfecting both the present work and Kellicott's "Odonata of 

 Ohio." Specimens kindly loaned for the purpose by Messrs. Adams, 

 Hine and Williamson have enabled me to ascertain that the G. externus 

 Kell. and G. externus Wllmsn. are in reality G. crassus Hagen, as Mr. 

 Williamson suspects in this very paper. The true externus, although in-
