SYNOPSIS OF THE ANTHOPHILAX OF NORTH 

 AMERICA (COL.). 



By Alan S. Nicolay, 

 Brooklyn, N. Y. 



After taking several beautiful green specimens of this genus while 

 collecting in Maine during the month of May, 1916, I became greatly- 

 interested in the species of this group. While comparing specimens 

 with descriptions and all available material, I found the greatest con- 

 fusion existed in separating our forms. So at the suggestion of Mr. 

 Charles W. Leng, who has ever been ready with advice and kind offers 

 of assistance, I decided to revise the group including all the new 

 forms. 



Without the help and complete records of Dr. Edwin C. Van Dyke, 

 I am afraid our western species would still be in considerable con- 

 fusion, but he very kindly came to the rescue, not only revising my 

 key but also adding a new species, our eighth, to the genus. 



Through the kindness of Mr. Andrew J. Mutchler by permission 

 of Dr. Frank E. Lutz I have been able to examine the material in 

 the American Museum of Natural History. Mr. Charles Schaeffer 

 allowed me to inspect specimens in the collection of the Brooklyn 

 Museum. I also have to thank Messrs. William T. Davis, W. S. 

 Fisher and Ernest Shoemaker for records and loan of material. 



All the species inhabit mountainous districts preferably the higher 

 altitudes and are quite rare in collections. 



The genus Anthophilax was erected in 1850 by Le Conte^ to sep- 

 arate those forms having dilated labial palpi, head constricted behind 

 eyes, eleven jointed antennae inserted between the eyes, which are 

 emarginate ; thorax with rectangular hind angles moderately con- 

 stricted on each side and acutely tuberculate at sides. 



Table of the Species of Anthophilax Lec. 



I. Third joint of antennae long, as long or longer than the first and distinctly 



longer than fourth 2 



Third joint of antennae relatively short, shorter than the first and equal to 

 or but slightly longer than the fourth S
