1878.] 91 [ Scudder, 
prominence slightly swollen on the sides, the tip bluntly pointed; the 
upper surface is transversely rounded, and like the head sparsely and 
rather faintly punctate; beneath it is a little tumid, with a coarse 
basal tooth hardly breaking the continuity of the front of the fastig- 
ium and the head, and separated from the latter by a distinct though 
slight frontal incisure. Pronotum scabro-punctate, subcylindrical, the 
lateral carinz quite obsolete excepting on the posterior part of pos- 
terior lobe, and the deflected lobes curving insensibly from the disk ; 
posterior margin nearly straight. Tegmina only as long as the body 
and scarcely longer than the hind tibie. Fore and middle femora 
with one or two short spines on the apical half of the anterior lower 
carine; posterior femora slender, the apical half armed beneath 
on both carinz with distant spines; hind legss hort, the tibiz being 
a little more than half as long as the body. * Last dorsal segment of 
¢ abdomen strongly produced, on either side above and just within 
the cerci, into an arched, sharply pointed, triangular, thickened and 
apically compressed plate more than half as long as the cerci, the 
sides of the triangle a little concave; supraanal plate large, triangular, 
deeply bifid at tip, the two sides sharply pointed; anal cerci stout, 
incurved apically, both teeth arched and directed inward, the upper 
bulbous, directly overlying the under, the latter conical, both armed 
at tip with a finely pointed spine partaking of the curve of the arch 
and turned a little forward; styles large, equal, bluntly rounded at 
tip, depressed and canaliculate above, nearly as long as the anal 
cercl. 
Leneth of body, 28 mm.; of antenne, 57 mm.; of fastigium in 
front of eyes, 2 mm.; of tegmina 19.5 mm.; of hind tibize 16 mm. 
1 ¢. Cedar Keys, Florida, June 4, A. E. Schwarz. 
The brevity of the tegmina (hitherto unknown in Conocephalus ?) 
and the form of the fastigium give this insect a slight resemblance to 
Orchelimum. 
97. Conocephalus aries. A small but comparatively stout 
species, green, with fuscous flecks on the wings and minute blackish 
spots beneath the base of the spines on the legs, the lateral and 
frontal edges of the fastigium yellow, narrowly margined below with 
black. Fastigium short, stout, blunt, the basal third, from front 
edge of base of eyes, tapering rapidly; beyond equal, the tip broadly 
rounded, the length from front edge of eyes considerably less than 
the breadth at base, half as long again as the width in middle, the 
upper surface transversely arched, rounding insensibly to the sides,
