they should not be so regarded. Typically, the unstriped form 
has a less compressed head and prothorax, wider and less 
prominent vertex and facial costa, often slightly stouter fore 
femora and shorter hind femora. This form inhabits dry areas 
on sandy and gravelly soils, railroad embankments, etc., clothed 
with bunch-grass, scrub-oak, sweet-fern and pitch-pine thickets. 
The striped form is characteristic of wet, swampy tracts, among 
rank grass, weeds, and bushes. What the relation is between 
the two forms and their different environments has yet to be 
determined. 
S. ruhiginosa has been taken at Manchester, N. H. (Fogg); 
Andover, Peabody, Dedham, Wellesley, and Provincetown, 
Mass.; and in numerous localities in Rhode Island and Connec- 
ticut. *S. alutacea is known from Wareham and West Chop, 
Mass., and several localities in southern Connecticut. Dates of 
capture of adults range from August 5 to October 30. Owing 
to the greater activity of the males, this sex seems greatly to out- 
number the other, though both fly freely and far, frequently 
alighting on tall bushes and trees after being flushed from the 
grass of the swamps where they live. 
This species is distinctly injurious when occurring in numbers 
on or near cranberry bogs, owing to its destruction of the growing 
cranberries, which it bites open and destroys in search of the 
seeds.
