new species of Membracide. 419 
Hab. Rio Janeiro and Botafogo, Brazil; a fair series. 
(Belgium Museum Collection.) 
Both these species have the facies of Hnchotype, rather 
than of Potnia, the pronotum being distinctly and 
regularly ribbed ; but the presence of four apical areas on 
the wings prevent their being classed with the former 
genus as at present constituted. 
Enchotype concimna, sp. n. 
Parvula, castanea, pronoto fortiter rugose punctato, linea cen- 
trali aliisque utrinque irregularibus utrinque elevatis, humeris a 
fronte viso obtuse prominulis, cornu antico fere recto, brevi, lato, 
acuto, unicarinato, apice postico longo, acuto ; tegminibus hyalinis 
venis testaceis, apicem versus fuscis ; pedibus testaceis. 
A small dark castaneous species,, with the pronotum coarsely 
and rugosely punctured, with the central line and others on each 
side elevated, and with the shoulders, if viewed from the front, 
obtusely prominent ; anterior horn situated just above metopidium, 
short, broad, and almost upright, and sharp at apex; tegmina 
vitreous, with the veins testaceous towards base, darker towards 
apex; legs testaceous. Long. cum tegm.6mm,, lat. int. hum. 4 mm. 
Hab. Cuba (Mayr., Vienna Museum Collection). 
This species is closely allied to Hnchotype fairmairet, 
Stal. (Hoplophora fairmairei, Guér.), but differs in the 
shape of the prothoracic horn, which is much shorter, 
less porrect, and more upright, and also in the smaller 
size, less strong pubescense and darker venation of the 
tegmina. 
Enchotype is a sub-genus of Stal, which is closely 
allied to Potnia, from which it is chiefly separated by the 
fact that the wings have three instead of four apical 
areas ; it is very distinct from Hoplophora, of which it is 
by some authors reckoned as a sub-genus. ‘The species 
above described is plainly an Hnchotype, but it has 
besides the three apical alar veins a very minute fourth 
one on the exterior margin, which appears to be a thick- 
ening of a vein and to be quite distinct from the exterior 
area of Potnia. 
Hoplophora unicolor, sp. n. 
Longa, lata, parallela, capite et pronoto toto rufo-ferrugineo 
unicolori, ille parvo, hoe fortiter punctato, humeris prominulis,
