ing veins have already been described. In the female the wing covers are quite 
unlike those of the male, being much narrower, and wrapped more closely 
around the body, giving this sex a more slender form. The flattened upper 
portion is cut up into many small cells which are mostly square and are formed 
by six or seven parallel veins which arise from the base of the wing covers and 
from the inner rib-vein and run obliquely backwards and slightly inwards to 
the inner margin, and are connected to each other by numerous transverse 
veinlets. The deflected outer or costal area is similar to that of the males. 
The longitudinal rib-veins do not form any elliptic area like that in tlie 
male. The wings are folded together lengthwise under the wing covers, 
and are of the same length with them in the male, whilst in the female they 
are longer and project beyond their tips the eighth of an inch or more, resem¬ 
bling little conical tails. 
The four forward legs are rather slender and of moderate length and clothed 
with fine short soft hairs. The thighs are cylindrical and have a shallow groove 
along their under side. The shanks are but half as thick as the thighs and 
taper slightly towards their tips. The forward ones near their bases are flat¬ 
tened and widened and show on both sides a deeply impressed oval and almost 
transparent spot appearing like a scar. The feet have three joints, of which 
the first one is long and cylindrical, the middle one is very small and only 
about as long as it is wide, and the last one with the claws at its tip does not 
differ from the same joints in the hind feet. The hind thighs are very long and 
slender, nearly equaling the tip of the wings and of the ovipositor. They are 
much thickened towards their bases, flattened on their inner side and strongly 
convex or rounded on their outer side. They have a narrow straight grobvc 
running their whole length, both on the inner and the outor side, and an ele¬ 
vated line along their lower edge. The hind shanks are also long and very 
slender and thread-like, equaling the thighs in their length and like them 
clothed with very fine short soft hairs, in addition to which they have along 
their hind side two rows of small sharp spines or prickles which reach almost 
to the knee, with three or four pairs of coarser ones towards their lower end, 
and a crown of coarse ones at the tip whereof two are much longer and have 
small thorn-like points branching from them. All these spines are white with 
their points black. The hind feet arc covered with minuto spines or thorn-like 
points, which are very densely crowded on their under sides. These feet 
have four joints, one more than is found in other insects of the cricket kind, 
but the articulation to the middle of these joints is so slight in the present 
species that it is often wholly imperceptible in the dried specimens. The basal 
joint is long and cylindrical and forms three-fourths of the total length of the 
foot. The second joint is of the same diameter with the first, but is quite 
short, only as long as wide, with the suture at its base slight and often dis¬ 
cerned with difficulty. It is cylindrical and divided into two parts by a suture 
running lengthwise upon each side. The upper half forms two large stout 
spines, the bases of which are articulated to the apex of the first joint, then- 
lower edge is joined by a suture to the lower half of this second joint its 
whole length, their tips only being free, jutting onward and overlaying the 
third joint more than half its length, each spine tapering to a point which is
