(agamic forms), or hardly enlarged (bisexual forms); antennae of 
moderate length with (rarely) 13 or (usually) 14 or even 15 segments 
in some varieties; the thorax of moderate size (in long- winged varie- 
ties) or much reduced (in short- winged varieties) ; the parapsidal 
grooves usually continuous but in many cases (especially short- winged 
varieties) poorly defined or even lacking anteriorly; anterior parallel 
lines poorly defined or lacking; median groove absent or shallowly in- 
dicated posteriorly; mesopleura (agamic forms) in part smooth and 
shining, with a sparse to heavy punctation, more or less hairy; or 
mesopleura (bisexual forms) more nearly smooth and naked; abdomen 
entirely smooth and naked except for the hairs latero-basally, or (in 
two varieties of nubila and in many short-winged varieties) hairy on 
all of the segments laterally; hypopygial spine moderately broad, drawn 
out at the ventral tip (in long-winged and some short- winged forms) ; 
or hypopygial spine of uniform width for nearly the whole length and 
bluntly rounded at the tip (in most short-winged forms) ; tarsal claws 
of moderate weight, toothed or (in mellea) merely broadened basally 
and nearly simple in some varieties; wings long, about 1.30 times the 
body length, or half that length, or as short as 0.14 of the body in
