close. Legs sometimes long and slendei*, sometimes short and robust. 
Coxse very strong and elongated. Femora broadly flattened, usually 
.strong. Tibite spurred and with lateral spines, rarely without 
the latter ; fore ones with a spur and a very small spine, or 
unarmed ; hind ones with two spurs and one to four ranges of 
lateral spines on the outside, and generally vvitli one range on the 
inner side ; I’ai’ely are all the tibite unarmed. Tarsi long and 
slender, or short and strong, metatarsus frecpiently prickly. 
Wings ovate, longer or shorter than the abdomen, with a broad, 
rounded, or more or less cuneiformly narrowed base ; distinctly 
haired or only microscopically pubescent ; pellucid, more or less 
tinted with a pale shade of brown, sometimes hyaline, sometimes 
variegated ; iridescent. Five or six longitudinal veins, the fifth 
generally, and the sixth always, rudimentary ; three cross-veins, of 
which two — the humeral and mai'ginal cross-veins — are always 
present, the sub-costal cross-vein being frequently missing ; third 
and fourth longitudinal veins almost always, and the second longitu- 
dinal sometimes, forked. No discoidal cell. The costal vein, 
first longitudinal vein, and fourth longitudinal vein are always 
complete, and form the principal veins which issue from the 
root. The costal vein either extends quite to the apex of the 
wing or stops a short distance before it ; the first longitudinal 
vein joins the costa ; and the fourth longitudinal vein i-uns in a 
more or less long curve to the posterior margin of the wing. 
From the first longitudinal vein near or at its root branches ofl‘, 
between it and tlie costa, the au.xiliary vein. The auxiliary vein 
is either long or short, bent upwards and going into the costa, bent 
downwards and running into the first longitudinal vein, disap- 
pearing gradually in its cour.se in the .sub-costal cell, or, lastly, 
forming only a tooth, which may be very short or somewhat 
lengthened, sometimes inclining downward.s, and appearing to lean 
towards the Hist longitudinal vein; the auxiliary vein is connected 
by the humeral cross-vein near its base, with the costa, and 
frequently it is united to the Hr.st longitudinal vein by the 
sub-costal cross- vein. Second longitudinal vein issuing from the 
fourth longitudinal vein at or before its middle or near its root ;
