THE MOUNT DESERT REGION 21 



thought it Ix'si to follow comprehensive works, because it 

 provides uniformity, and to stick to one system until there is 

 a revision of a family available to which students may be 

 referred with confidence. 



The Coleoptera follow the Catalogue of the Coleoptera of 

 America, etc. by Charles W. Leng, and many of the specimens 

 have been checked by Mr. C. A. Frost, Mr. K. F. Chamberlain, 

 Mr. H. S. Barbel- and Mr. W. S. Fisher. 



The Diptera are listed according to the Diptera of X. A. 

 by Dr. C. H. Curran, who has determined the greater part of 

 the material and reviewed the manuscript. 



Exceptions are made in the Tipulidae, which have all been 

 determined and the manuscript written bv my friend, Dr. C. 

 P. Alexander, the mosquitoes, which follow the works of Dr. 

 Robert Matheson, who has kindly advised me, and the Tendi- 

 pedidae, which conforms to the recent revision by Dr. Henry 

 R. Townes, Jr., who has revised the manuscript. 



The classification of the Arachnida, Acarina, etc. has been 

 brought up to date through the kindness of Dr. W. J. Gertsch, 

 who has determined all of the forms and read the manuscript. 



For the Odonata I have used An Annotated List of the 

 Odonata of Maine by Dr. D. J. Borror, Can. Ent., vol. LXXVI, 

 July, 1944. 



The catalogue of the Hemiptera of N. A., etc. by E. P. Van 

 Duzee, 1917, has been used for that Order, and the manuscript 

 edited by Dr. R. I. Sailer, of the Bureau of Entomology, etc., 

 Washington, with the exception of the Aphididae, which fol- 

 lows Dr. Edith M. Patch in the Hemiptera of Connecticut 

 State Geological and National History Survey Bulletin 34, 

 1923. All of the aphid determinations are due to the kindness 

 of Mrs. J. B. Adams of the Laboratory of Plant Pathology, 

 Fredericton, X. B. 



Dr. J. B. Watson of the College of Agriculture, University 

 of Florida, has been most kind in determining the thrips, 

 thus making it possible to include them.
