Tas. VI. Fig. 1—4. 
Antenne filiform, four-jointed, the first elongate, all cylindrical, 
porrected, black ; the last joint shortest and incurvate. Head 
shorter than the thorax; eyes prominent; snout inflected, 
short. Thorax roundish, convex, smooth; thicker and 
shorter than the abdomen. Body sublinear, of eight di- 
stinct rings and a dilated tail, pointed at the apex, and fur- 
nished on each side with a pencilled tuft and a hooked 
seta. Wings incumbent, cruciate, membranaceous, hyaline, 
subequal. Legs, the anterior pair simple, stronger than the 
rest, porrected ; the tarsi two-jointed. The anterior thighs | 
compressed, with the inferior margins densely hairy ; the 
second pair twice as long as the first, and having their in- 
ferior margin ciliated; the third pair rather longer than the 
second, with the thighs cylindrical, armed, as in the Grass- 
hopper tribe; the tarsi of the four posterior feet are appa- 
rently two-jointed, but so finely tapered as to require a strong 
lens to detect the articulation and the didactyle claws. 
'The prevailing colour of the insect is a light brown; the thighs 
of the first pair of legs longitudinally streaked with black ; 
thorax and sides beneath whitish silvery down. 
Length of the insect from the base of the snout to the end of the 
tail eleven lines.
