the Rouge River, north of Dearborn, Mich., with a view to noting the mortality 

 of bird life during the nesting period under natural conditions and to compare 

 them later with artificial or protected states, such as in the use of nesting 

 boxes and with their natural and other enemies removed. 



They have led the author to conclude that birds have no infallible protective 

 Instincts and that evolution is such a slow process that a species is liable to 

 diminish greatly in changing habits to meet new conditions, such as the destruc- 

 tion of forests naturally impose. Those nesting in trees appear, on the whole, 

 to have a better chance than the ground nesters, and those using holes in trees 

 apparently are better off than those nesting outside. 



The red-winged blackbird. — A study in the ecology of a cat-tail marsh, 

 A. A. Allen (Abs. of Proc. Linn. Soc. N. Y., No. 24-25 {1914), pp. 43-128, pis. 

 22, figs. 2; abs. in Auk, 31 {1914), No. 3, pp. 414, 415).— A report of biological 

 studies of Agclaius ph(jcnicens, conducted in large part near Ithaca, N. Y. The 

 first part of the work (pp. 48-74) deals with the environment, and the second 

 part (pp. 74-126) with the life history and ecology. 



" During the greater part of the year the red-wing obtains its food outside 

 of the marsh, and that which it does secure here, is taken, without selection, 

 from the preponderant forms as they occur in succession. Its dependence upon 

 the marsh, or, in other words, the reason for its being a marsh bird, lies in the 

 shelter which it or its offspring receives. ... It spends hardly more time 

 in the marsh than is necessary to rear its young." 



A l)ibliography of 41 titles is appended.

The forest insects of central Europe: A text-book and handbook, K. 

 EscHEBiCH {Die ForstinscTctcn Mittelciiropas. Ein Lehr- und Handbuch. Bcrlm, 

 1914, vol. 1, pp. XII-\-433, pi. 1, figs. 248; rev. in Jour. Econ. Ent., 7 {1914), 

 No. 4^ PP- 350-352). — This volume furnishes a general introduction to the 

 structure and life history of insects and the fundamental principles of practical 

 forest entomology. The several chapters deal with their classification, mor- 

 phology, internal anatomy and physiology, reproduction, economic importance, 

 natural limitation of insect increase, prevention and control, etc. 



Entomological notes, L. H. Gough {Agr. Jour. Egypt, 3 {1914), No. 2, pp. 

 103-106, pi. 1). — The notes here presented relate to Pimpla roborator, a parasite 

 of the pink bollworm fairly common around Cairo which is thoug)ht to 

 have recently taken to preying on Gelechia larvae in Egypt; Crytoblabes 

 gnidicUa, a small pyralid moth that has been reared from cotton bolls collected 

 at several points in Egypt; EphcMia cautella, a pyralid known as the Kharga 

 Oasis date worm, which feeds on half ripe dates ; and the pomegranate butter- 

 fly {Virachola (Deudorix) livia), the larva of which damages pomegranates and 

 also feeds on dates, sunt pods, and pods of Acacia cdgworthi. 



Common insects of the garden, C. P. Gillette {Colorado Sta. Bui. 199 

 {1914), pp. 40~48). — This bulletin contains descriptions of the more commonA / 

 garden insects, together with suggestions for their control. 



An efficient and practicable method for controlling melon lice, C. E. Durst 

 {IlUnois Sta. Bui. 174 {1914), PP- 321-334. figs. 3),— In tests by the station of 

 the more important in.secticides during a period of 12 years none has given as 

 satisfactory results as blackleaf 40, work with which has covered 3 years.
