A monograph.ic revision of the twisted winged insects comprising the 

 order Strepsiptera Kirby, W. D. Pierce ( U. S. Nat. Mus. Bui. 66, pp. XII + 

 232, pis. 15, flgs. 3, map ] ; rev. in Jour. Ecnn. Ent., 3 {1910), No. 2, pp. 252, 

 253). — The author is unable to accept the view that these parasitic insects 

 are modified representatives of the Coleoptera. He regards them as forming a 

 separate order on a distinct line of descent from that of the Coleoptera and 

 nearer the Hymenoptera and Diptera and as highly specialized as the highest 

 insects in any of tlie orders. Four superfamilies, 37 genera, and 109 species 

 are described. In the large list of host species at least 28 that are injurious 

 are recorded. A glossary of terms, and an extensive bibliography are included 

 in the work, which is riclily illustrated by pen drawings and photographs. 



The review is by W. M. Wheeler. 



Studies of the Ixodoidea of Brazil, C. J. Rohr (Estiiilos sobrc Ixcklidas do 

 Brasil. Rio dc Janeiro, 1909, pp. 220, pis. 6, flgs. 30). — Following a brief intro- 

 duction the author takes up the external and internal anatomy of ticks, both 

 gross and microscopic. He next presents an account of their biology and 

 reports the details of an extensive study of 6 of the species which occur in 

 Brazil (Argas miniatus, Margaropus annidatus mieropliis, lUvmaphijsalis prox- 

 ima, Amhlyomma cajennense, A. gohlii, and A. varium). The classification is 

 then dealt with, 45 species being listed as occurring in that country. The geo- 

 graphical distribution and hosts of these species are shown in tabular form and 

 a bibliography is appended. 



New North American Acarina, H. E. Ewing (Trans. Acad. Sci. St. Louis, 18 

 (1909). No. 5, pp. 53-77, pis. .'/). — In this paper 32 species are described, which 

 are distributed in 14 genera and 7 families. 



A systematic and biological study of the Acarina of Illinois, H. E. Ewing 

 (Univ. Ill, Univ. Studies, 3 (1909), No. 6, pp. 120, pis. 9, flgs. 6).— Although 

 this work is intended to be of value chiefiy to the acarologist because of its 

 systematic nature, some space has been given to the biology of the group, which 

 may be of interest or value to the entomologist. Two chapters are also devoted 

 to the explanation of the methods of collection and preservation of specimens. 



Methods of controlling tobacco insects, A. C. Morgan ( U. S. Dept. Agr., Bur. 

 Ent. Circ. 123, pp. 17, flgs. 11). — This circular, in which the author gives direc- 

 tions for the control of several important insect pests of tobacco, contains 

 information in addition to that presented in the paper previously noted (E. S. K., 

 21, p. 155). The recommendations made are based upon investigations conducted 

 since July, 1907, in the dark tobacco districts of Kentucky and Tennessee in 

 cooperation with the Tennessee Station. 



For the control of cutworms where tobacco follows a clover sod, it is again 

 recommended that the sod be r'lovvod under in the fall or winter and kept free 

 from vegetation by disking or harrowing. Wheu sod land is plowed only a 

 short time before setting the tobacco a trap bait may be used to rid the field of 

 the worms. In 1908 cutworms in plant beds were controlled by spraying with 

 arsenate of lead. 



The injury by the tobacco flea beetle in Tennessee and Kentucky in 1907 is 

 estimated at $2,000,000. In these States the beetles begin to emerge from
