tint being either a dull rusty, yellowish, or smoky brown, with 
markings of fuscous or black. In life a grayer tone prevails than 
is shown by cabinet specimens. 
Unobtrusive as a clod of the earth itself, there is nothing spec- 
tacular about either the person or career of the Dusky, or Dingy 
Locust. Tinted like the 
soil, a lump of animated 
dust, this plebeian creature 
spends its humble life liter-

accompaniment to the footsteps of the stroller in the fields on 
sunny days. 
Years ago I recorded (Journ. N. Y. Ent. Soc, vol. 4, p. 19, 1896) 
two modes of stridulation practiced by it while on the ground, in 
which the hind femora were the chief instruments employed; 
but the noise produced at this time is so very faint as to be 
scarcely noticeable unless the performer is directly under one's 
eye and ear. 
Blatchley speaks of its note in flight as "a harsh droning or 
buzzing sound, somewhat resembling that of a bumblebee, but 
louder. It is begun after the insect has risen three or four feet 
above the ground, and is continued until it begins to descend, 
being kept up continuously while it is flying horizontally. The
