112 THE EEPOET OF THE No. 36 



THE ENTOMOLOGICAL EECOED, 1919.

The collecting season of 1919 does not appear to have provided any marked 

 variation from the preceding year. In the Middle West a continuation of the droiight 

 in southern sections was especially favourable to the development of dry-loving in- 

 sects, more notably Orthoptera, which in some parts increased to injurious numbers. 

 Somewhat similar conditions prevailed in British Columbia and probably to a lesser 

 extent in Ontario. Collecting, generally, was reported to have been good during 

 the first part of the season but later became less so. It is gratifying to report that 

 more attention is being devoted to hitherto neglected orders; as a result a far 

 broader knowledge of the distribution of Canadian insects is being obtained. 



During 1919, students of insects in Canada, have, as in previous years, been 

 much assisted in their studies by various specialists, particularly those resident in 

 the United States. To all who have assisted us, we extend our grateful thanks. 



Literature. 



Among the publications which have appeared during 1919, the following are 

 of interest to Canadian students. 



Bowman, Kenneth. Annotated Check List of the Macrolepidoptera of 

 Alberta. Published by the Alberta Natural History Society, Eed Deer, Alta., 16 

 pp., February, 1919. In the preparation of this list the author has "endeavoured 

 to provide an epitome of what has been accomplished by students of this order 

 within the province to date, as an aid, not only to present workers but those wlio 

 will follow after." We were very glad indeed to receive this list. It is a very useful 

 contribution. 



Canadian Arctic Expedition (1913-1918) Insect Eeports. These report^ 

 on the insects of the various orders collected by members of the expedition were 

 published in 1919, with the exception of the one on the Lepidoptera which was 

 issued early in January, 1920. They comprise Vol. Ill of the Eeport of the 

 Canadian Arctic Expedition. Ottawa: J. de Labroquerie Tache, Printer to the 

 King's Most Excellent Majesty. 



Part A: Collembola, by Justus W. Folsom, 29 pp., 8 plates. Twelve species 

 are discussed, three of which are described as new. The plates illustrate structural 

 characters. 



Part B: Neuropteroid Insects, by Nathan Banks, 5 pages, 1 plate. Five 

 species are definitely determined, two of which are described as new. Two addi- 

 tional generic determinations are given. The plate illustrates genitalia of the two 

 new species and views of other male characters. 



Part C: Diptera, 90 pp. Crane flies, by C. P. Alexander; Mosquitoes by H. 

 G. Dyar, and other Diptera l)y J. E. Malloch. In the first portion on the Tipulidae, 

 sixteen species are reported upon. Of these, thirteen are new. The six plates 

 accompanying the section, illustrate wings, antennae and other structures. The 

 mosquitoes represented three species one of which only is definitely determined and 

 'this is described as new. The third section reporting upon other Diptera collected, 

 comprises pages 34 to 90, (10 plates). The number of species listed is ninety-three.
