THE CANADIAN ENTOMOLOGIST. 157 



Helloides, as was to be expected, was found at several points, 

 although nowhere commonly, the greatest number seen on any one day 

 being six or seven at Foster City. It was also observed at Norway, 

 Waucedah, Brown Lake, Tomahawk Lake, Jackson Lake, etc. There 

 were two generations, the first one being met with during the latter .part 

 of Tune and the first part of July, the second one in fresh specimens on 

 August 9th and 14th. Michigan is the most eastern State in which the 

 species has yet been found, although Dickinson County is in about the 

 same longitude (87°-88° west) as Lake County, in the north-western part 

 of Indiana', where helloides is also known. This is a western butterfly, 

 and its occurrence in the Upper Peninsula is an addition to the western 

 element in the fauna of that region. 



Two other species of the genus, liypophheas and thoc, were also met 

 with in the County, but not at any time in numbers.
