the margins of the tegmina. These last organs are somewhat pointed at their tips, 
and furnished with five narrow apical areas, and either two or three discoidals, but the 
neuration is not constant in all the species, and the discoidals may be subdivided by 
furcation. 
IBICEPS FALCATUS, n.s. 
(Plate LIY. fig. 6.) 
Concolorous sienna brown, Suprahumerals long, stout, flat, divergent and 
reflexed at an angle when viewed from the back. Posterior horn carinated, longer 
than the abdomen, and concealing the scutellum. Legs small and not much dilated. 
Tegmina pointed at their tips, hyaline but ratherfumose, with long brown parallel 
nervures, discoidals two, with basal sub-divisions. 
Expanse, 14 mm. Size, 7x8 mm.

Mr. J. Tepper’s Collection, taken in November. 
IBICEPS ANSATUS, n.s. 
(Plate LIY. figs. 7, 7a, 7b.) 
Uniformly shining fuscous. Metopidium rises high and perpendicularly above 
the frons, and then diverges into two bent suprahumerals. A strong carina runs 
from between the eyes to the point of divarication. Scutellum concealed, but the 
posterior horn rapidly narrows into a taper, curved apex, reaching nearly to the tips 
of the tegmina. 
Abdomen pale fuscous. Two patches of inconspicuous yellow occur, one behind 
each eye, and another on each side of the dorsum. Eyes prominent and sub-cylindrical. 
Tegmina long and brown, with five apical and two (three ?) discoidal areas. 
Apical tips of wing ochreous. 
Two specimens, one a female.

IBICEPS LABATUS. 
(Plate LV. figs. 1, la.) 
Pronotum brown and coarsely punctured. Suprahumerals thin and flat by the 
front view, but broad and angularly reflexed at the tips by the side aspect. Pronotal 
horn stout and slighly sinuous. An irregular yellowish patch occurs under each 
wing-insertion, and another on each costa of the tegmina The membrane fuscous
