MEMBR A GIDJE. 
more carinae, tlie posterior part ending in a sharp point, slightly projecting beyond 
the abdomen ; abdomen free from the pronotum, robust and ringed ; colour slate- 
grey or black; hind-legs stout with coarse serratures; brown. Pronotum much 
punctured, black, with a conspicuous ochreous spot, succeeded by a smaller one, near 
the apex, which last is sharp and black. Tegmina black or dark slate-colour, each 
having a broad corrugated limbus ; wings more transparent. 
The frontal portion of the pronotum is straight, and falls perpendicularly to the 
eyes. 
Tegmina with four open apical areas. 
Although this insect appears to be typical, Canon Fowler expresses much difficulty 
in its identification. He says it is much mixed in collections, and even thinks it 
probable that it is a variation of E. binotata to be described afterwards. 
Size, 16x9 mm.

ENCHENOPA MONOCEROS. 
(Plate IV. figs. 9 to 9b.) 
Evchenopa monoceros, Gerru. Am. et Serv. p. 535. Membracis monoceros, Fairm. p. 253. 
Pronotum conical in front; perpendicular from the head ; concolorous cinnamon- 
brown, except near the apices of the tegmina, where it is paler. Sometimes also a 
yellowish patch occurs before the hinder end of the pronotum. Tarsi ochreous- 
brown. This description only in part agrees with that given by Fairmaire, but it 
is the average of ten or more specimens in the Hope and the B.M. Collections. 
E. monoceros forms the type insect for Enchenopa of Am. et Serv. 
Size, 9x5 mm.

ENCHOPHYLLUM DUBIUM, Fowler. 
(Plate V. fig. 2.) 
Enchophyllum dubium, Fowler, Tab. I. figs. 9, 9a, 9b, p. 8. 
There is a proximity in this insect to the genus Enclienojia, and it seems to be 
particularly close to E. albodorsum, which, however, is differently coloured. 
My drawing is from an example kindly lent to me by Canon Fowler. 
Size, 8x5 mm.
