FicurEs 67-114

quent designation of Osborn, 1926b:172.

Length of male 6.6-14.8 mm, of female 7.5-16.0 mm. 
Head varying from slightly to moderately produced, its median length from 
three-tenths to three-fourths its interocular width and from one-fifth to slightly 
more than four-tenths transocular width, anterior margin nearly always 
broadly rounded in dorsal aspect, rarely (D. jemima (Distant), D. syrphoidula 
(Jacobi)) subangulate, without a carina at transition from crown to face, ocelli 
located behind a line between anterior eye angles in most species, rarely on a 
line between anterior eye angles, variable interspecifically as to relative dis- 
tance from midline of crown and adjacent anterior eye angle, surface of crown 
convex or with a slight concavity near midlength, disk without sculpturing or 
setae, lateral clypeal sutures extending onto crown, often not attaining ocelli; 
antennal ledges with anterior margins obliquely convex or obliquely recti- 
linear in lateral view; face convex, very finely pubescent ventrally, muscle im- 
pressions distinct, transclypeal suture nearly always incomplete (complete in 
lectotype of Tettigonia corixoides Fowler), clypellus slightly swollen, not strong- 
ly produced. 
Thorax with pronotal width less than transocular width of head, lateral 
margins subparallel or slightly convergent posteriorly, dorsopleural carinae 
oblique and complete; posterior margin concave; surface without sculpturing 
or transversely rugose, without pubescence; posterior half of scutellum not 
transversely striate. Forewing membranous apically and in most species with 
a considerable membranous area -before anteapical cells, veins distinct 
apically, distinct or not anteapically, not elevated, with four apical cells and 
base of fourth more proximal than base of third, without an anteapical plexus 
of veins, texture hyaline (exception: D. gaudens (Walker)) with coriaceous 
areas in most species; wings of female at rest exceeding apex of ovipositor. 
Hindwing much shorter than forewing, with or without a conspicuously en- 
larged jugal lobe partially separated from remainder of wing by a deep ex- 
cision. Hindleg with meron exposed, at least in male, with forewing in rest 
position; femoral setal formula 2:1:1 or 2:1:1:1; first tarsomere with length 
much greater than combined length of second and third tarsomeres, with bi- 
seriate minute macrosetae on plantar surface. 
Male genitalia: Pygofer well produced or not, with macrosetae numerous, 
regularly dispersed or not, processes usually absent, not differentially 
sclerotized when present. Plates triangular, separate throughout their length 
or very rarely fused for a very short distance at their bases, with longi- 
tudinally uniseriate or multiseriate macrosetae and with at least a few 
elongate microsetae on lateral margins. Style with length relative to con- 
nective variable interspecifically, with or without distinct preapical lobe. Con-
