thoracic projection forming an obtuse angle ; dorsal spines minute, of 

 nearly uniform size, brown tipped ; segments with rows of brown dots, 

 and also of brownish markings. Imago emerges in ten days. 



The hutterjlt/, usually rare, is met with abundantly some years, flying 

 about clover fields, with the short and rapid flight of the Skippers. Tt 

 is the most numerous about the middle of September. Several years 

 ago, prior to my collecting, I observed at the Adirondack Iron Works 

 in this State, immense numbers of either this species or can/iii, upon 

 and about the blossoms of the common thistle {Cirsium lanrpoldtnm) 

 growing by the road-side. So abundant were they, and so little dis- 

 posed to flight, that any desired number, could in a short time, have 

 been taken by hand. T have also captured himtera on the summit ni' 

 Mt. Marcy.
