Buffalo and in ravine sedge marshes on the Warren Woods 

 Preserve. Several specimens were captured among sparse dry 

 grass and dewberry vines on a cinder-strewn railroad embank- 

 ment at New Buffalo. In a partially dried up bog just back 

 •of the dunes nymphs of this species fairly swarmed in early 

 July among a dense four-foot growth of ferns which filled it; 

 they have been placed under this form, since the habitat was 

 jnore moist than those w^iich rubiginosa usually frequents. 

 The typical form seems to range over a greater variety of hab- 

 itats than rubiginosa in this region. 



This species was taken at Lakeside on September 18 by 

 Hancock.

 New Buffalo. September 2, 1919, 14 males. 2 females; September 9, 



1920, 2 males. 

 ? New Buffalo, June 30, 1919, 4 immature specimens. 



Near the Warren Woods this form was taken in a neglected 

 ^rass-grown raspberry and blackberry patch and in a small 

 shrubby opening in the margin of a patch of second growth 

 woods. At New Buft'alo it was abundant in a sandy field 

 covered -with a sparse growth of dry grass and overrun with 

 dewberry vines. Along a grassy roadside bordered with shrubs 

 and young trees nymphs of this species (probably form rubi- 

 ginosa, from the character of the habitat) were found in num- 

 bers on June 30; on September 2 adults were taken in the 

 same locality. 



Three of the male specimens have a fairly evident medio- 

 longitudinal pale stripe on the pronotum and closed tegmina, 

 but are otherwise typical of the rubiginosa form.
