Notes on Habitats of Grasshoppers at Douglas Lake, 



Michigan (Orth.) 

 By ARTHUR G. VESTAL, University of Colorado. 



A list of the Orthoptera at the summer biological station of 

 the University of Michigan has been published, 1 but no rec- 

 ords of dates or habitats have been included. During the sum- 

 mer of 1912 the writer collected Acridiidae at Douglas Lake, 

 in Cheboygan County, seventeen miles south of the tip of the 

 southern peninsula. In addition to records and habitat notes 

 obtained, six species were taken which had not been listed 

 from the region. The Tettiginae collected were few, and the 

 notes below refer only to members of our other three sub- 

 families. 



Douglas Lake is irregular in contour, and about four miles 

 long. The beach is narrow, in many places wanting. More 

 than half the area adjoining the lake is sandy burnt-over pine 

 lands, now occupied by open woodland of large-toothed aspen, 

 with undergrowth of bracken fern and blueberry. Clay mo- 

 rainic lands are partly under cultivation, but mostly occupied 

 by hardwood forest of beach, maple and hemlock, or by hard- 

 wood clearing. There are also grassland areas, meadows and 

 sedge growths, cedar bogs, and open peat bogs. 



Subfamily TRYX'ALINAE. 



Chloealtis conspersa (Harris). July 25, 1912, in small opening 

 in hardwood forest, on shrubbery ; July 25, open hardwood forest, on 

 sandy loam surface; July 30, hardwood clearing; Aug. n, aspen 

 forest, shaded lichen-covered surface. The species is typical of thick- 

 ets, open forest situations, clearings and forest borders, depending upon 

 wood, as is well known, for egg-laying sites. It is not found in num- 

 bers. Not formerly known in the region. 



Stenobothrus curtipennis (Harris). July 30, on willow shrubs 

 in moist swale of sand-bar ; Aug. 9, moist weed-patch near tile drain 

 in cultivated field; Aug. II, beach-grass dunes. (This locality, on the 

 lake shore, is unusual for the species. Occasional specimens were 

 washed ashore and picked up alive on the beach. The single beach- 

 grass specimen may have come from the lake) ; Aug. 11, grassy border
