rounded in front; no lateral foveoloe; the advance in front of the eyes 
not quite equal to the length of the eye; a very slight median carina. 
Face quite oblique; seen from the side curves slightly inward below 
the vertex; regularly widening from the apex of the eyes downward, 
rounded transversely; the carinse generally slight and obtuse, but 
sometimes slightly prominent; frontal costa slightly prominent between 
the antennae, but not prominent below, gradually expanding below, 
more or less suleate; lateral carinse more or less distinct, nearly straight, 
reaching the corners of the face. Antennse about as long as the head 
and pronotum, enlarged and flattened at the base, acuminate at the 
apex, triquetrous. Eyes oblong-ovate, oblique, and placed well for¬ 
ward near the antennse. Pronotum a little longer than the head, 
truncate in front; hind border very obtusely angled; sides flat, per¬ 
pendicular, straight and very nearly or quite parallel; tricarinate, the 
three carinse about equal, distinct but not prominent, straight, parallel; 
posterior transverse incision situated a little behind the middle, bends 
forward in the middle, and cuts the median carina; the two anterior 
incisions sub-obsolete; the posterior margin of the side somewhat regu¬ 
larly though slightly curved inward, the lower posterior angle being 
sub-acute. Elytra and wings pass the posterior femora, and are about 
as long as the abdomen;*the former are narrow and obliquely trun¬ 
cate at the apex. Abdomen sub-cylindrical, elongate, slightly enlarged 
at the apex; the upper valves of the ovipostor unusually long and 
exserted. Posterior femora shorter than the abdomen, not reaching 
the extremity of the elytra, slender, being but slightly enlarged at 
the base. 
General color as given above. Antennae and generally the front 
legs in all the varieties pale reddish brown; the lateral carinse brown; 
the eyes and a spot below them brown. The elytra with a few fus¬ 
cous or dark dots along the disk; wings pellucid or slightly tinged 
with yellownsh at the base; nerves of the anterior portion roseate in 
the green variety; somewhat dusky in the brown specimens. Length, 
1.50 to l.Yo; elytra, 1.10 to 1.25 inches. 
Male .—Similar to female, except that it is very much smaller, 
rather more compressed on the sides, head slightly more ascending, 
face slightly more oblique, vertex rather more acute. The back is 
usually green; the sides in all cases so far as I have observed, 
entirely and uniformly fuscous, without spots or stripes. Length, 1.00 
to 1.15; elytra, .80 to .90 inches. 
This species, so far as I am aware, has been found only at one 
point in this State, and that a very limited area near Murphysboro, 
Jackson county. 
It is fond of damp, swampy places covered with a rich growth of 
grass, not too heavily swarded. As it is found south as far as the 
West Indies, it is probable Jackson county is the extreme northern 
limit of its district.
