MEMBRA CIDJE. 
maire’s description, “ Entierement noir,” with the pronotum “ portant en dessous 
une dent carree.” 
The insect named Centrotus hamifer by Walker, with the habitat Natal, must be a 
distinct species. 
Size, 8x4 mm. 
Habitat. —Bugaba, Panama. 
This appears to be an abundant insect, and occurs in many parts of America. 
CAMPYLOCENTRUS CAVIPENNIS, Fowl. 
(Plate LV. figs. 8, 8a.) 
Fowler, Gnamptocentrus cavipennis, l.c. Tab. IX, fig. 1G, p. 153. 
Very shining dark brown, or with a blue-black sheen. 
The discs of the tegmina furnished with a concave diseoidal area, the circumference 
of which is raised and forms a cup-like depression, whence the specific name. The 
points of the suprahumerals are blackish, as also are the legs. A small yellow spot 
is on the scutellum, and the eyes also are yellow. There often is a tomentose spot 
on the dorsum, which, however, is easily rubbed off. The node under the posterior 
horn is large and swollen. 
Size, 7 x 4 mm. 
Habitat .—Yera Paz, Guatemala, Panama. Taken from 2000 to 4000 feet 
elevation. 
This and the next described species so much resemble Campylocentrus, that I 
include it in that genus, rather than group it under Gnamptocentrus as Fowler 
has done. 
The number of the apical and diseoidal areas are apparently the same, but 
nevertheless there is some small difference in the neuration of the tegmina. 
CAMPYLOCENTRUS SINUATUS, Fowl. 
(Plate LYI. figs. 1, la.) 
Fowl. Gnamptocentrus sinuatus, B.C.A. p. 152. 
Small. According to Fowler it is allied to Campylocentrus, with the tegmina 
furnished with a similar number of apical and diseoidal areas, but differently disposed. 
Colour black or dark brown, pitchy, with a grey pubescence, which is easily rubbed 
off. Tegmina hyaline, ochreous at the apices, with dark cloudings at the bases, 
where there is often a luteous spot. 
My figure is from the Fowler Collection, but the specimen is partly defective. 
The suprahumerals are easily seen when viewed from the front. Drawn at a greater 
magnification. The pronotal horn appears to be recurved and abnormal.
