88 THE CANADIAN ENTOMOLOGIST 



at hand and are sufificient to show that the species has been 

 .thoroughly misunderstood and that it cannot be referred to this 

 subfaniih-. It is, in fact, a member of that group, whatever it 

 may eventually be called, that includes the present subfamilies 

 Monophlebinae and Margarodinae, although it cannot be referred 

 to either of these groups as they are at present defined for it seems 

 to combine the characters of both. I shall discuss the species at 

 some length in a later note. 



The facts here presented are too few to permit of any \ery 

 sweeping generalities, yet they are suggestive enough and I present 

 them~at this time, in spite of their fragmentary character, in order 

 to call attention to them and to their possible significance. 



It will be noted that, with the exception of the species of 

 Orlhezia, all the forms in which these spiracles have been noted 

 belong to the two subfamilies Monophlebinae and Margarodinae. 

 Conversely, it is possible, if indeed not probable, that all the 

 members of these groups will eventually be found to possess such 

 organs. It, therefore, appears that we may have .available a 

 taxonomic elemerft that has not ,been fully utilized and that may 

 throw a considerable amount of light upon the relationships of 

 these forms. . Whether or not the presence of abdominal spiracles 

 is any evidence of a close relationship between the Ortheziinae and 

 the other two subfarhilies remains to be seen, but there is some 

 other evidence that the present division between the Mono- 

 phlebinae and the Margarodinae is by no means as clear as it has 

 been thought. 



The Board of Regents of the University of Minnesota at their 

 meeting on January 18th elected Dr. W. A^ Riley, of Cornell, 

 Professor of Parasitology and Chief of the Division of Economic 

 Zoology. Associate Professor A. G. Ruggles was, at the same 

 time, appointed Station Entomologist, which position carries with 

 it the ofifice of State Entomologist. At the December meeting of 

 the Board Professor F. L. Washburn, who has held the position 

 of State Entomologist in Minnesota for nearly sixteen years, 

 asked and obtained permission to be relieved of that position and 

 its attendant police duties, and the action of the Board on the 

 18th was necessarv to fill the vacancv thus caused."
