MEMBRA CIDJE. 
The female is ochreous brown, with long hyaline tegmina veined with yellow ; 
pronotum with a Hat horn more dilated at the tip than is seen in the male, and 
marked by three carinations; surface punctured and rather mottled with brown ; 
Dorsum unarmed, and extending posteriorly nearly to the tips of the tegmina. 
These last organs are narrow, and show at least four apical cells. 
It is difficult exactly to decide on the neuration, as it seems to differ in the sexes. 
I figure the tegmina of both sexes. Though nearer to Potnia than any other genus, 
I somewhat doubtfully place this insect here. 
Size, 9x5 mm. and 14 x 4 mm. 
Habitat. —Bogota, 
Hope Collection. 
POTNIA BREVICORNIS, Fowler. 
(Plate XXI. figs. 5, 5a.) 
B.C.A. p. 46, Tab. IV. fig. 9. 
Very small; pronotal process short and blunt as if truncated, tipped with brown ; 
colour ochreous, blotched with brown; tegmina transparent and furnished with 
brown parallel nervures. 
Fowler remarks that this species is very near to Potnia asoda/is of Dr. Coding, an 
insect which inhabits California, My figure is from the Hope Collection with the 
habitat Volcan de Chiriqui up to 8000 feet elevation. 
Size, 5x3 mm. 
There is another insect in the Hope Collection from Bogota, which I cannot 
separate from that above described, except from its larger size, viz., 6x3 mm., and 
a little difference in the colour of the wing veining. 
The following insects have been described by others and may be placed under 
Potnia: 
P. venosa, Germ. (Membracis) 1821 ; Ent. iv. 19, 16. 
Umbonia venosa, Fairm. l.c. p. 278. 
P.jaculus, Stal. Vet. Akad. Handl. Fab. l.c. (2) viii. p. 38. 
U. indicator, Fairm. l.c. p. 279, Plate VI. fig. 15. 
P. Jansoni, Fowl. Trans. Ent. Soc. (1894), p. 418. 
P. perobtusa, Fowl. l.c. (1894). 
P. (jranadensis, Fowl. l.c. 45, Fairm. p. 273 (Hoplopliora). 
Genus : OETIIOPLOPHORA. 
Fowler, l.c. p. 46. 
This genus has been formed to receive the single species Orthoplophora Salvini. 
It differs from Potnia, inasmuch as the tegmina show four apical areas; and from 
Enchotype, in having a broader head and differently shaped dorsum and horn.
