Mktcad.f, C. L. The Syrphidae of Ohio : Ohio Biological Survey, Bulletin No. 

 1, Vol. I.; Ohio State University, Columbus, 1913, pp. 7-123, plates i to xi. This 

 extremely valuable contribution is very welcome. The insects of this family are 

 of very considerable economic importance. The paper is divided into three parts: 

 Part I. — ^General discussion of the family, characters, etc. ; Part II. — Key to known 

 larvae, synopsis of life-history studies, etc. ; Part III, — Keys to genera, species, etc. 

 This bulletin will be of special use to Ontario students, 



MoRLEY, Claude. A Eevision of the Ichneumonidae based on the Collection in 

 the British Museum (Natural History) with Descriptions of New Genera and 

 Species: British Museum (Natural History), 1913. Part IL, Tribes Rhyssides, 

 Echthromorphides, Anomalides and Paniscides; pp. 140, 1 plate (coloured). 

 This is a continuation of the " Revision " commenced by the same author in 1912. 

 In this second part 291 species are included, 71 of which are described as new.

Wheeler, William Morton. A Revision of the Ants of the Genus Formica 

 (Linne) Mayr; Bulletin of the Museum of Comparative Zoology, Vol. LIII, No. 

 10, Cambridge, Mass., October, 1913. In this most useful contribution, pp. 379-565, 

 the author recognizes 31 species, 19 subspecies, and 43 varieties as belonging to the 

 North American fauna. Many Canadian records are given, and several species, sub- 

 species, and varieties are described as new. One form which occurs in Canada is 

 given specific rank. The taxonomic and other notes given after many of the descrip- 

 tions will be found of much value to students of these insects. In order to facilitate 

 the identification of the various species, subspecies, and varieties of Formica the 

 author gives dictotomic tables of the worker phases, as well as tables of the females 

 of the rufa and microgyria groups.
