twice distinctly notched; the middle portion shortest and rounded; 
the whole of the di&k, especially the posterior lobe, more or less cov¬ 
ered with small tubercles; lateral carinae obsolete on the anterior 
lobes, and obtuse and indistinct on the posterior lobe; the posterior 
angle a little larger than a right-angle. Elytra and wings extend be¬ 
yond the apex of the abdomen. Posterior femora rather short, not 
reaching the tip of the abdomen in the female; broad at base, with 
a sharp, elevated upper carina, which suddenly decreases about one- 
third the length from the apex; the low^er edge generally hairy. An¬ 
tennae longer than the head and pronotum, filiform. 
Color .—Fuscous and pale yellowish-brow r n, or ash, about equally di% 
tributed in stripes and spots, the ash or yellowish brown portions 
more or less mottled with fuscous dots and points. The dark on the head 
as follows: two stripes running back from the eyes, one from the upper, 
the other from the lower corner; the lower portion of the cheeks and 
the lower margin of the face; and some dots on the margins of the 
frontal costa. On the pronotum a broad pale stripe runs along each 
lateral carina, converging in front of the middle; the margins of the 
posterior portion are pale, joined interiorly by a black stripe; the central 
space pale; the sides marked with alternate stripes of pale and fuscous. 
Elytra fuscous at the base, becoming transparent a little beyond the 
middle, where the netted nervules suddenly cease; a narrow whitish 
line along the angle; the lower field has two sub-quadrate black spots 
separated by an elongate whitish spot. Wings transparent; base 
greenish-yellow; a narrow fuscous band across the middle; apex pel¬ 
lucid, with a few fuscous dots at the tip. Posterior femora ash-col- 
‘*red, with three black spots on the upper margin of the outer face; 
oase and a band on the inside black. Posterior tibiae with a broad 
white ring near the base, rest blue; tarsi yellow. Venter and pectus 
■white. 
Dimensions. —Length, 1 inch; elytra, 0.92 inch; posterior femora, 
0.56 inch; posterior tibiae, 0.48 inch. 
I have taken a few specimens of this species in Southern Illinois, 
but it is by no means common. 
20. HIPPISCUS NEGLECTUS. Thos. 
Somewhat like the male of Oe. corallipes , Ilald. Vertex broad, 
transverse; the large central foveola is divided by a single or double 
carina, which runs from the center of the front margin back two- 
thirds across it; when double, the infolding of the margin, seen from 
the front, resembles a w; lateral foveolae shallow, but distinct, frontal 
costa bi-sulcate above the ocellus, slightly sulcate below. Median ca¬ 
rina of the pronotum simply a raised line, distinctly severed by the
