twice as long as wide in the bisexual form. Mesonotum of the agamic 
forms more or less closely but shallowly punctate, with scattering, mod- 
erately long, yellow hairs, in part smooth, in part coriaceous to finely 
rugose between the punctation; the mesonotum of the bisexual females 
finely or sparingly roughened and sparsely hairy if not entirely smooth 
and naked; parapsidal grooves continuous or (in a few long- winged 
forms and several short-winged forms) more or less obliterated an- 
teriorly, not wide, of moderate depth, smooth at bottom (except an- 
teriorly in a few cases), gradually convergent but still not close together 
posteriorly, gradually divergent anteriorly (or sharply divergent if the 
thorax is very large and robust) ; median groove usually lacking (but 
some varieties have an indication of some median groove, especially 
posteriorly); anterior parallel lines (in most long-winged agamic forms) 
narrow to broad, moderately separated, wholly or in part finely punctate, 
or (especially in short- winged varieties and bisexual forms) not well 
defined, more obscure or obliterated anteriorly, slightly broadened and 
more or less divergent posteriorly; lateral lines (in long- winged agamic 
forms) mostly smooth, naked, rather broad, approaching the scutellum 
posteriorly but not extending to the parapsidal grooves anteriorly, these 
lines more or less obliterated in some long-winged varieties and in most 
short-winged varieties and bisexual forms. Scutellum of normal size, 
of moderate width, distinctly longer than wide (in long- winged varieties) 
or small and not much longer than wide (in the forms with the shortest 
wings), hardly broadened posteriorly, well rounded at the tip (more 
pointed in some short- winged varieties) ; flattened to cushion-shaped, 
often (not always) with a slight flattening, depression, or elevation 
along the median, longitudinal line; punctate and finely or more heavily 
rugose; scatteringly hairy, the hairs densest along the edges; with a 
shallow, arcuate foveal groove (which often grades into the anterior 
depression of the scutellar disk, especially in short- winged varieties), 
this groove undivided or at least with not more than a very fine, in- 
definite division into foveae; a well-defined foveal ridge separating the 
scutellum from the rest of the mesonotum (the ridge indefinite in some 
short- winged and bisexual forms) ; pronotum very narrow anteriorly 
(in long- winged forms), or broadened and distinctly visible dorsally (in 
many short-winged forms) ; laterally rugose and punctate, with not long, 
not dense, yellowish hairs. Mesopleura (of agamic forms) at least in 
part and sometimes wholly punctate and scatteringly hairy, smooth and 
shining between the punctations; the mesopleura of bisexual forms more 
nearly smooth and naked. 
Abdomen of moderate size (in long- winged forms) or larger (in 
short-winged forms), one-third to three-quarters again as long as high; 
in some varieties not produced dorsally or ventrally, with the second 
segment not tongue-shaped; in other varieties (and in all bisexual 
forms) more or less produced dorsally with the second segment tongue- 
shaped; the second segment covering one-half to two-thirds of the whole 
abdomen (less than a half in some short- winged forms) ; the abdomen 
usually smooth, shining, and naked except for sparse patches of hairs 
latero-basally (with even these hairs reduced in bisexual forms), or
