Length 7.7-12.0 mm. 
Head well produced, median length of crown varying from six-tenths of, to 
equal to, interocular width, and from four-tenths to slightly more than six- 
tenths transocular width, anterior margin broadly rounded in dorsal view, 
without a carina at transition from crown to face, ocelli located on a line be- 
tween anterior eye angles, each equidistant from median line of crown and 
adjacent anterior eye angle, crown with a median longitudinal fovea, lateral 
clypeal sutures extending onto crown and attaining ocelli, antennal ledges not 
protuberant, in lateral view with anterior margins oblique and rectilinear or 
slightly convex; clypeus convex except medially where it is slightly or dis- 
tinctly (J. flammea (Signoret)) flattened, muscle impressions not very distinct, 
face without pubescence, transclypeal suture obscure medially, clypellus not 
produced, but with profile of its lower portion more nearly horizontal than 
contour of its basal portion. 
Thorax with pronotal width greater than transocular width of head, lateral 
margins convergent anteriorly, dorsopleural carinae complete, posterior 
margin varying intraspecifically from slightly concave to slightly convex, disk 
with or without transverse rugae, not pubescent; scutellum usually not striate 
behind transverse sulcus. Forewing broadened apically, with a membrane, 
veins usually distinct and elevated, with four apical cells of which all but in- 
ner are of almost same length, second apical cell not strongly narrowed 
apically (exception: J. perplexa, n. sp.), without an apical plexus of veins, tex- 
ture varying from mostly hyaline to opaque and mostly coriaceous, apical 
margin slightly concave; forewings of female in rest position exceeding apex of 
ovipositor. Hindleg with femoral setal formula 2:1:1, length of first hind tar- 
somere slightly greater than combined length of two more distal tarsomeres 
and with two parallel rows of small setae on plantar surface. 
Male genitalia: Pygofer moderately produced, posterior margin regularly 
convex, with a number of macrosetae arising irregularly over most of disk, or 
limited to its posterior half, pygofer without processes (exceptions: J. circultfera 
(Taschenberg) and perplexa.) Plates triangular, not extending posteriorly as far 
as pygofer apex, each with uniseriate macrosetae. Style extending posteriorly 
to a variable degree interspecifically compared with posterior extent of con- 
nective, without a preapical lobe, apex variable interspecifically, but not 
acute. Connective varying interspecifically. Aedeagus symmetrical, variable 
interspecifically but without processes arising at base (exception: one 
specimen of circulifera with a median basiventral process). Paraphyses sym- 
_ metrical with rami slender, tapering, and acute. 
Female abdominal sternum VII from slightly to strongly produced 
posteriorly, posterior margin varying interspecifically from slightly convex to
