THE CANADIAN ENTOMOLOGIST, 87 



Walker* records " C. bifida, var. ?" from Hudson's Bay, and Butlerf 

 doubtfully refers a specimen from Mendocino Co., Cal., to Cerura bicuspis, 

 Borkh., but it seems probable that these specimens belong to some of the 

 American species, and at any rate these references are not positive enough 

 to warrant the inclusion of the names in the list. 



Cerura sco/opendrina is known to me only by Boisduval's description, 

 which is vague, and I have not included it in the table, 



Cinereoides is a form o{ cinerea, as I have pointed out, and I consider 

 Candida as a variety of scitiscripta chiefly on the authority of Mr. Graef 

 and of Dr. Strecker. Mr. Graef has shown me that there is no difference in 

 pattern between the two, while Dr. Strecker assures me that they were 

 " raised from the same lot of eggs." 



THE MOOSE FLY— A NEW H.^.MATOBIA. 



BY WM. A. SNOW, UNIVERSITY OF KANSAS, LAWRENCE. 



Entomologists will be interested to learn of the occurrence of a near 

 relative of the Horn Fly, Hcematobia serrata, in the middle of the great 

 cranberry swamps of Northern Minnesota. These vast low areas extend 

 for hundreds of square miles in the vicinity of the Lake of Woods. They 

 are the favored home of the American moose, and the hope of obtaining 

 some specimens of this animal for the museum of the University of 

 Kansas led Professor L. L. Dyche of that institution to traverse these 

 dangerous marshes. Professor Dyche has recently returned after remain- 

 ing for over three months in the very centre of the swamps, camping upon 

 the occasional sand ridges which cross the region ; and to him I am 

 indebted for specimens of a new Hcematobia. 



The flies were noticed first upon skinning the first moose, when a 

 number of them were discovered in the animal's rectum, into which they 

 had crawled for two or three inches in order to deposit their eggs in the 

 excreta. The dejecta upon the ground were also found to contain 

 hundreds of the eggs. Altogether nineteen moose were killed and in 

 almost every case these flies were observed about them, remaining upon
