ORTHOPTERA. 
The scientific name of the genus that includes the cricket 
is Aclieta^ and our common species is 
the Aclieta ahhreviata (Fig. 69), so 
named from the shortness of its wings, 
which do not extend beyond the wing- 
covers. It is about three quarters of 
an inch in length, of a black color, with 
a brownish tiiifye at the base of the 
wing-covers, and a pale line on each 
side above the deflexed border. The 
pale line is most distinct in the female, 
and is oftentimes entirely wanting in 
the male. 
We have another species Avith very 
short or abortive wings ; it is entirely 
of a black color, and measures six tenths of an inch in length 
from the head to the end of the body. It may be called 
Aclieta nigra^^ the black cricket. 
A third species, differing from these two in being entirely 
destitute of wings, and in having the Aving-covers proportion¬ 
ally much shorter, and the last joint of the feelers (gpalpi) 
almost twice the length of the preceding joint, is furthermore 
distinguished from them by its greatly inferior size, and its 
different colorino;. It measures from three to above four 
tenths of an inch in length, and A^aries in color from dusky 
broAvn to rusty black, the wing-covers and hindmost thighs 
being ahvays somewhat lighter. In the broAvnish-colored 
varieties three longitudinal black lines are distinctly Ausible 
on the top of the head, and a black line on each side of 
the thorax, Avhich is continued along the sides of the Aving- 
coA^ers to their tips. This black line on the Aving-coA^ers is 
ne\"er Avanting, even in the darkest varieties. The hindmost 
thighs have, on the outside, three rows of short oblique 
black lines, presenting someAvhat of a tAvilled appearance.
