SATYRODES I. 



It seems to be an early feeder ; I have never found larvae feeding in a state of 

 nature after five o'clock in the niornino-." 



Superintendent I. N. Mitchell, of Fond du Lac, Wisconsin, writes : " Canthus 

 occurs here, but my knowledge of its habits is entirely from meeting it in south- 

 ern Michigan. I have taken many specimens there in two neighboring spots, in 

 Cass County. One of these is a large meadow on the border of a lake, the 

 meadow being covered with high grass. In some parts also thickly covered with 

 trees and shrubs, but in others only partially with clumps of willow and shrubs, 

 leaving open spaces of grass. It is in this last part that Canthus is most com- 

 mon, though it flies in all parts, and among the trees. It usually starts out of 

 the grass near a clump of willow, flies among the bushes, in and out, dodges 

 around them, where Eurytrls flies through them. Canthus is much more easily 

 taken than the other species. The second spot referred to is a small marsh, 

 bordered by an abrupt hill which is wooded with beech and maple. In the marsh 

 are grasses three or four feet high, willows, tamarack, sumac, and shrubs scat- 

 tered about. I often started Canthus from the leaves of the beeches on the 

 edges of the marsh, but never very far from the marsh. They usually made 

 toward it when disturbed, and often settled near the upper ends of the grass 

 stems, but low enough below the tops to be well hidden. They often alight on 

 the trunks, limbs, or leaves of trees or bushes growing in the marsh, and I 

 have started them out by throwing clods. Occasionally I took them on the 

 stump of a recently felled maple, attracted by the sweet sap, and then in 

 company with Graptas and Vanessans." 



Professor Edward T. Owen, at Madison, Wisconsin, says : " I take Cantlms in 

 large numbers in and about our swamps. It is quite rare even a quarter of a 

 mile from them. The tall swamp grass is its favorite haunt." 



Mr. Edward A. Dodge, of Louisiana, western Missouri, writes : " Canthus 

 was a not uncommon insect in both Illinois and Nebraska. So far as I know 

 from eighteen years' experience, it was to be found only in grassy and weedy 

 sloughs, flying weakly, close to the ground, and alighting on the grass stems." 



Mr. Worthington writes from Chicago : " Canthus is equally abundant in open 

 dry woods, dense ridges, or swamps. About the Calumet Lakes, on the wooded 

 ridges, in swamp land, it is abundant. It also flies in the open oak woods on the 

 high sand hills further north and east. North of the city, in the wooded lands, 

 thirty to fifty feet above the lake, it is quite common. I remember the species 

 distinctly as taken near and north of Milwaukee, Wisconsin, where all the land is 

 high and rolling. From its habit of visiting the prairie morning and evening, I 

 judge it may breed there ; but a flight in the open in broad day is certain death, 

 as they are an easy prey to the dragon-flies."
