way, of course, future volumes will be made much more useful for those who are 

 studying specially the lepidoptera of our country. 



JoHANNSEN, 0. A. The Mycetophilidae of North America : Maine Agric. Exp. 

 Station, Bull. 172, Part I, (March, 1910), pp. 209-276, plates 3'; Bull. 180, Pavt 

 II, (June, 1910), pp. 125-192, plates 4. This monographic treatment of the 

 Fungus Gnats of North America is a most valuable contribution to our knowledge 

 of diptera. In Part I the lower and economically less important subfamilies 

 Bolitophilinge, Mygetobiins", Diadocidiinse, Ceroplatinse and Macrocerinae, are 

 treated ; in Part II the Sciophilinse are dealt with. 



KiRBY, W. F. A Synonymic Catalogue of Orthoptera, Vol. Ill, Locustidse vel 

 Acridiidae; British Museum (Natural History), March, 1910. This volume com- 

 pletes Mr. Kirby's general Catalogue of the Order Orthoptera. It is a book of 674 

 pages, and therefore considerably larger than Vols. I and II. This is owing to 

 the fact that the Locustidse (the short-horned Grasshoppers or Migratory Locusts) 

 is a much larger family than the others. This work will be of the greatest use to 

 systematists, and now that the whole Catalogue has been completed, the order Orth- 

 optera will doubtless attract more and more students from year to year. Pages 

 562 to 586 are given up to "Additions and Corrections" to the three volumes. 



MuTTKOWSKi, RicHAED A. Catalogue of the Odonata of North America: 

 Bulletin of the Public Museum of the City of Milwaukee, Vol. I, article I, pp. 

 207. This well prepared catalogue, which was issued on June 27th, is a publication 

 which will be widely welcomed by students of the Odonata. Such a catalogue has 

 been much wanted. It presents in convenient form what purports to be a complete 

 list of these insects from the North American region. The author has had the co- 

 operation of the leading students in this order in the preparation of the catalogue; 

 the classification and nomenclature employed, therefore, represents the more ap- 

 proved and advanced ideas of odonatologists. The publication is an important 

 one, and should be in the hands of all Canadian students of these neuropteroid 

 insects. 



Pierce, W. Dwigiit. A Monographic Pevision of the Twisted Winged. Insects 

 comprising the Order Strepsiptera Kirby. Smithsonian Institution : U. S. Nat. 

 Museum, Bulletin G6. Eeceived Jany. 7, 1910. In this extensive contribution of 

 23'2 pages, 37 genera are treated of, comprising 103 species. Sixty-two new species 

 are described from North America. The introductory chapters on " History " and 

 " Biology " give much information about these interesting insects, which have been 

 so little studied by North American students. Fifteen plates appear at the end of 

 the Bulletin. 



PoHWER, S. A. On a Collection of Tenthredinoidea from Eastern Canada. 

 Proc. U. S. Nat. Museum, Vol. 38, pages 197-209; published June 6, 1910. This 

 paper is a report of an interesting collection of sawflies made by Mr. A. Gordon 

 Leavitt, in the County of St. John, New Brunswick. Fifty-three different species 

 are listed, 12 of which are described as new. 



Smith, John B. A List of New Jersey Insects : Annual Eeport of the New 

 Jersey State Museum, 1909; pp. 888. This report, with the exception of 13 pages, 

 is devoted to Dr. Smith's New List of the Insects of New Jersey. No less than 

 10,385 different species are listed, comprising 3,486 genera and 331 families. In 

 the 1899 list 8,537 species were included. Considerable progress has therefore been 

 made in a knowledge of the insects of the State. This List is an extremely useful 

 publication. Unfortunately its edition is limited, and it will be impossible to sup- 

 ply everyone who will want this work with a copy.
