THE CANADIAN ENTOMOLOGIST. 27 



In Areolatus the metallic points in the ocelli are pale blue, and are 

 arranged more or less in rows in the ocelli lengthwise of the wing. In 

 Mitchellii they are, if in rows at all, across the wing. In Areolatus the 

 transverse lines on the under side are ferruginous, and the second and 

 third always unite near anal angle of hind wings. In Mitchellii they are 

 more of a brownish-yellow ; in the males the second and third lines never 

 unite, but the first and second, and the third and fourth always unite 

 leaving a little space between their rounded ends ; in the females only 

 one out of four had the second and third distinctly united. In Areolatics 

 the metallic points are pale blue. In Mitchellii they are lighter, being 

 more of a silvery colour, giving none of the real blue reflection, unless 

 seen at a very oblique light, and then very pale. 



Described from six males and four females taken by my friend, Pro- 

 fessor J. N. Mitchell, in Cass County, Michigan, to whom I dedi 

 cate the species. They were found in upland dry meadows, about ten 

 miles from the Indiana line. Professor Mitchell is of the opinion that the 

 species has been found as far north as Kent County, Michigan.
