A new insectary, E. D. Sanderson (New Hampsliirc f^ta. 8ci. (Jontrib. 3, 

 pp. 389, 300, pi. 1; Jour. Ecoii. Ent., 2 (1909), No. 6, pp. 389, 390, pi. 1).—A 

 novel iusectary erected at the New Hampshire Station dnring the summer of 

 1009 is described and Illustrated. The object in its erection was to furnish 

 more natural conditions for life history work than could be obtained in a glass 

 house. The insectary is 18 by 24 ft., with a permanent wooden workshop, 6 by 

 13 ft., at one end. The roof is of double canvas and the sides of the rearing 

 room of 18-mesh bronze screening. It is erected in such a way that it can be 

 taken down and stored during the winter. The iusectary is stated to have been 

 erected at a cost of approximately .$400. 



The life zones of Indiana as illustrated by the distribution of Orthoptera 

 and Coleoptera within the State, W. S. Blatchley (Proc. Ind. Acad. ticL, 

 1908, pp. 185-191). — This account is based upon collections made of insects 

 of Indiana during a period of 20 years. About 150 species of Orthoptera and 

 some 2,700 species of Coleoptera have been collected. 



" The facts brought out regarding the distribution of Orthoptera and Coleop- 

 tera in Indiana, which are supplemented by numerous field notes on other 

 groups of insect and animal life, and on the flowering plants, prove conclusively 

 that the ' transition zone,' represented by the Alleghanian fauna and flora, over- 

 lai)s the northern fourth of the State, while the ' lower austral zone,' represented 

 by the Austroriparian fauna and flora, overlaps the greater part of the south- 

 ern third. The Carolinian fauna and flora of the Upper Austral embraces, 

 of course, the prevailing forms of life in the State, 93 of the 148 species of 

 Orthoptera belonging to it. The majority of these range over the entire State, 

 mingling with the representatives of the Alleghanian fauna in the north and 

 with those of the Austroriparian fauna in the southern third. The proportion 

 of Coleoptera belonging to the Carolinian fauna will be about the same, but the 

 exact figures can not as yet be given. To the Carolinian fauna belong also the 

 great majority of the other forms of animal life in the State." 



Dragonflies of the Mississippi Valley collected during the pearl mussel 

 investigations on the Mississippi River, July and August, 1907, C. B. Wil- 

 son (Proc. U. S. Nat. Mus., 36 (1909), pp. 653-671).— X list is here presented of 

 the different species obtained in connection with the pearl mussel investigations 

 on the Mississippi River and its tributaries during the summer of 1907, with 

 their geographic and seasonal distribution. 



On Brazilian grasshoppers of the subfamilies Pyrgomorphinae and Lo- 

 custinse, -J. A. G. Rehn (Proc. U. 8. Nat. Mus., 36 (1909), pp. 109-163, figs. 

 39). — Fifty-three species are treated in this paper, of which 17 are new. Four 

 new genera are also described. 



A contribution to the knowledge of the Orthoptera of Sumatra, J. A. G. 

 Rehn (BuJ. Amcr. 21us. Nat. Hist., 36 (1909), pp. 177-211, figs. 3i).— Eighty 

 species are considered in this paper. Three genera and 17 species are described 

 as new to science. 



New genera and species of Illinois Thysanoptera, J. D. Hood (Bui. HI. 

 Stair Lnh. Nat. Hist., 8 (1908). Art. 2, pp. 361-378, figs. 9).— Five genera 

 ( Heterothrips, Lissothrips, Plectrothrips, Xeothrips, Allothrips) and 15 species 

 from Illinois are described as new to science. 



Life history of Corizus lateralis, J. C. Hambleton (Ami. Ent. Soc. Amer., 

 2 (1909), No. If, pp. 272-276, pi. 1). — This species is said to have been very 

 abundant in the neighborhood of Columbus, Ohio, during the summer of 1909. 

 Polygonum pcnnsi/Ivanicum, its host plant, is a native annual that is quite gen- 

 erally distributed over the whole T'nited States. It is said that adults were also 

 taken on P. pcrsicariu, a species introduced from Europe, and widely distributed,
