MEMBRA CIDjE. 
Genus : ENCHOPHYLLUM. 
Amyot et Serville, Stal., Fowler, B.C.A. p. 7. 
Pronotal horn variable in length, but more or less pointed forwards. Stal sub¬ 
divides this genus into Phyllotropis, Enchenopa, and Tropidocera. 
The species are represented in North, Central, and South America. The Biologia 
Cen. Amer. figures three of these, but the type E. cruentatum is not included in the 
descriptive list of that work. 
The chief difference between this and the next genus, Enchenopa, appears to 
consist in the absence in the latter, of a carina behind the pronotal horn. 
Nevertheless, this horn, curved downwards, with a carina of variable length, is also 
seen in some species of Enchenopa. I must leave it for the present for others to decide 
whether these characters are sufficiently important to make them generic. I think 
it now best in this respect to follow Canon Fowler’s lead. 
ENCHOPHYLLITM CRUENTATUM. 
(Plate IY. figs. 5 and 5a.) 
Enchophyllum cruentatum , Germ. Silb. Rev. Ent. iii. 226 ; Am. Serv. Hemip. 534 (Plate ix. fig. 3.) 
Phyllotropis , Stal. Yet. Akad. Handl. (2) 8 (1), p. 62 ; Fowler, B.C.A. p. 7. 
Pronotal crest much as in Membracis fasciata, but furnished in front with a strong 
black curved horn carinated at the sides. Colour bright crimson-red, with the 
horn springing from a black patch. This is succeeded by a broad black dorsal band, 
which is carried above the shoulders. The apex is red, with a black point. Body, 
legs and tegmina dense black. The last with a broad corrugated limbus. 
First and second tibiae spatulate ; the last pair simple and finely serrated. 
Size, 14 to 12 mm. from tip of horn to end of tegmina. 
Habitat .—Rio de la Plata, Brazil. 
Figured from an example in the British Museum. 
ENCHOPHYLLUM MELALEUCUM. 
(Plate IY. figs. 5 to 5c.) 
Enchophyllum melaleucum, Fowler, Tab. I. figs. 7 to 7b, p. 7. Enchenopa melanoleuca, Walk., 
l.c. Ins. Sand. p. 59 ; Fowler, plate ii. fig. 7. Tropidocera melaleuca, Still. 
Sooty-black, with a white spot on the metopidiurn and two others on the dorsum. 
The carina behind the horn is well marked. This insect has a great resemblance to 
E. notata, but it is larger.
