the Eastern United States." As reproduced, they will be enjoyed by 

 many to whom they were previously inaccessible. They can not fail 

 of proving delightful popular reading, as may appear from the titles 

 of some of the chapters cited — "Butterflies as Botanists" (four 

 others given). 



The Natural History of Aquatic Insects: by Prof. L. C. Mial, F. R. 

 S. (The Nation, for October 31, 1895, No. 1583, pp. 317-318, cols. 

 3, 1—23 cm.) 



In a brief notice of this volume it is commended as a contribution of 

 more than ordinary value to the knowledge of life-histories and habits 

 of aquatic insects. While purportmg to draw much from writings of 

 Reaumur and other "old zoologists," several of the studies are new, 

 as that, for example, of Simulium, in which the strange manner of the 

 escape of the imago from the water is given. That nearly all the 

 orders of insects are rei)resented in aquatic forms will be a surprise to 

 many. The author maintains that all insects were originally terrestrial 

 and that they have gradually invaded both fresh and salt waters, and 

 cites the Tipulidas larvae as showing successive stages of this progress. 



The Box Elder Plant Bug. (Country Gentleman for October 31, 1895, 

 Ix, p. 786, cols. I, 2 — II cm.) 



Insects sent from McGregor, lo., as annoying from their abundance, 

 are the above-named plant-bug, Leptocoris trivlttatus (Say). Its habits, 

 history, etc., have been given in the Country Gentleman for September 

 27, 1894, and in the Fourth Report of the State Entotnologist, 1888. 

 The insect has not been reported from east of the Mississippi river, 

 but its occurrence on the west shore of that river would indicate that 

 it may have already extended into Wisconsin and Indiana.
