Mr. Schwarz called attention to the desirability of a more 

 thorough exploration of the isolated mountain ranges in southern 

 Arizona. From the little that is known of these regions it is safe 

 to say that a great many species will be found there that do not 

 occur in the corresponding zones of the plateau region of northern 

 Arizona, where the fauna is very little different from that of other 

 parts of the Rocky Mountains. Mr. Busck, on being questioned 

 as to the feeding habits of this genus, replied that nothing is 

 known concerning their habits, but that the larva? of the genera 

 most nearly allied to them spin webs and feed within them. Dr. 

 Dyar said that, in his opinion, the structure of the palpi in the 

 genus Dorata shows that this genus is not closely allied to the 

 genera whose feeding habits Mr. Busck mentioned, and that, 

 therefore, it would be unsafe to draw conclusions as to the feed 

 ing habits.
