THE CANADIAN ENTOMOLOGIST. 11 



The following records constitute our present knowledge of its 

 distribution: N.Wisconsin (Loew) ; Mass. (O. Sacken) ; Cheshire 

 Harbor, near Mt. Graylock, Mass., June 30 (I. W. Beecroft) ; Lake 

 Ganoga, North Mt., Pa., 2,300 ft., Aug. 29, 1897 (C. W. Johnson). 



Xylophagiis fasciains Say. 



"Wing dusky, fasciated; abdomen fasciated. Inhabits Indiana. 



"Body dusky; thorax, posterior portion honey-yellow; poisers 

 blackish at tip; wings dusky, a more distinct band on the middle 

 and at the tip; feet honey -yellow; hind tihice blackish; tergum 

 yellow, basal half of the four basal segments black; remaining seg- 

 ments nearly all black. Length over two-fifths of an inch. 



"By an accident the head and anterior part of the thorax of this 

 fine specimen were destroyed, but the above description \\{\\ 

 sufiiciently indicate the species. The wing nervures resemble those 

 of the maculatus Fabr." 



In the above description by Say, based on an imperfect speci- 

 men, I have italicized the parts showing discrepancies to Loew's 

 species. The diiTerences are too great to consider them the same; 

 the description of the bands on the wings, "on the middle and at 

 the tip," also does not agree with. Say's usual accuracy. The 

 locality, "Indiana," which is entirely in the upper Austral, would 

 also indicate a different species. Say's reference to maculatus, 

 which is a Xylomyia (= Solva Walk.), would indicate a closed 

 fourth posterior cell.
