breadth ; upper surface nearly flat, scarcely rounded, a little sca- 
brous, the sides separated from the summit by a distinct though slight 
carina; beneath, the whole forms a depending pointed cone, whose sides 
are scarcely less than a right angle with each other, and are separated 
by a pretty wide frontal incisure, by the slightly tuberculated tip of 
the front of the face which it overreaches. Pronotum densely 
punctate, broadening regularly from in front backward,1 more 
strongly in the ¢, the lateral carine distinct, though blunt, through- 
out, the hind margin gently convex, the deflected lobes sloping gently 
and regularly from a vertical position. Tegmina very long, moder- 
ately slender, very gently curved, the tip rounded, only a little below 
the middle, scarcely produced. Fore and middle femora with two or 
three minute teeth on the lower anterior carina; hind femora slender, 
delicately spined along nearly the whole under surface; hind legs 
long, the tibiz half as long as the wings. Last dorsal segment of the 
male abdomen deeply and very widely notched, being produced pos- 
teriorly at the sides to a large triangular tooth, slightly uncinate at 
tip; anal cerci stout, short and arcuate, the upper tooth very small, 
tumid, with a pretty long incurved and slightly recurved spine, lying 
almost upon the upper tooth, which is stout, compressed, conical 
and straight, directed inward and forward, armed at tip with a slight 
thorn; styles slender, cylindrical, tapering on the apical half to a 
blunt tip half as long as the anal cerci; ovipositor a little longer than 
the hind tibiz, not quite reaching the tip of the tegmina. .

from Dr. Gundlach with the Nos. ;44 and 55%; St. Thomas, received 
from Mr. P. R. Uhler; N. Orleans, from Mr. A. Sallé ; San Mateo 
del Mar, Tehuantepec, about lagoons, collected in February by 
Sumichrast; and from an unknown locality collected by Xantus. 
This species is very closely allied to C. obtusus Burm., but differs 
from it in itslonger legs, rather shorter fastigium and somewhat dif- 
ferently constructed male abdomen. 
99. Conocephalus retusus. A small and slender species, 
green, with a very faint pale band around the borders of the fastigium, 
more distinct and broader on the sides, edged beneath, in front only, 
1Jn asingle 9 from St. Thomas, which otherwise does not differ from the others, 
the disk of the pronotum is equal throughout.
