SPHONGOPHORUS (CLADONOTA) PAEADOXA, Germar. 
(Plate XIY. tig. 3, 3a, 3b, 3c.) 
Germ. l.c. 26, t. I. fig. 1. Fairm. l.c. p. 261. 
Brown ; the proceplmlon is erect, recurved, and long, dilated in the middle, and 
marked with a strong central carina; the apex in the male is cleft like a fish-tail, 
but in the female the apex is simple. There is considerable variation in the curve of 
this horn, it being more sinuous in some examples than in others ; the dorsal process 
is constricted into two globose knobs, with a smaller apical one, which suggests the 
form of the safety-valve apparatus on a locomotive engine ; surface as well as the 
tegmina finely punctured ; the last membranes are corrugated, sienna-brown, and 
greyish at their bases ; the males have three faint greyish spots at their apices ; first 
and second tibine pilose and spatulate. 
My figures are from specimens in the B.M. Collection. 
Size, 8x11 mm. 
Habitat. —Constancia, Brazil. January. 
SPHONGOPHORUS (CLADONOTA) NODOSUS, n.s. 
(Plate XIV. fig. 4, 4a, 4b.) 
Concolorous shining black, except the tegmina, which are warm sienna-brown, 
with a greyish tint at their bases, for about one-third; venation strong and darker; 
the procephalic horn is gnarled, rugose, and twisted into tubercles over the back, and 
stands erect; a globose tubercle, surmounted by a smaller one, is on the dorsum, the 
posterior apex of which does not reach to the tips of the tegmina. 
This curious insect has much the appearance of a piece of gnarled bark, and it 
must conceal itself very effectively. I cannot identify it with any described species. 
It does not agree with either S. ridiculus or S. ladicras of Walker. 
Size, 10 x 8 mm.

SPHONGOPHORUS (LOBOCLAD1SCA) BI-CLAVATUS, Westw. 
(Plate XIV. fig. 5.) 
Fairm. l.c. p. 262, PI. iv. fig. 4. Fowler, B.C.A. Tab. III. figs. 4-4a. 
The anterior horn varies much as to its upward projection. My figure shows it 
globular at the tip with a smaller hinder tooth ; the dorsal horn is fungoid in shape ;
