MEMBRA CIDAZ. 
Stoll gives a figure, apparently of a Horiola, in his Cigales tom. I., PI. 16, fig. 89, 
from Surinam. The connection here between an Asiatic and American form is 
interesting. 
Fowler says the genus is very variable, and he gives only one species in the Biologia 
of Central America. He thinks that many named forms should be treated as 
synonymous. 
HORIOLA ARCUATA. 
(Plate XXXII. fig. 8.) 
Horiola arcuata, Fowl. l.c. Tab. YI. figs. 20a, 20b. 
Darnis arcuata, Fab. 1). tincola, Fab. D. (jlabrata, Fab. D. elegantula, Perty, t. 35, fig. 11. 
Tragopa picta, Am. et Serv. l.c. p. 54(1. Horiola lineolata , Fairm. l.c. p. 492. 
Small, more acute than the next described species H. picta. Pronotum dark 
shining brown, and marked by two conspicuous orange semi-circular rings, which do 
not meet at the dorsal ridge. Two smaller reversed semi-circular spots occur lower 
down. The pronotal apex acute, and rather orange-coloured near the tip. The legs 
sordid yellow. A figure of the wing neuration is given in the B.C.A. (Tab. G, fig. 20) 
from which I have borrowed the above synonyms, which Canon Fowler deduced from 
a series from Bugaba. Stoll’s fig. p. 89, which he express^ states he received from 
Surinam is clearly II. arcuata. 
I have received specimens from Mr. Rosenberg which are smaller than the 
normal examples. They have an ochreous, angular band on each side, and a short 
transverse band in the middle. 
Taken during the dry season at Paramba, 3000 feet elevation. 
Size, 4x2 mm. 
Habitat .— Bugaba, Bogota, Ecuador. 
HORIOLA PICTA. 
(Plate XXXII. figs. 9, 9a, 9b.) 
Darnis picta, Fab. Tragopa picta, Am. et Serv. 
Small, scutiform ; head and eyes black and just visible from the back view ; colour 
shining sienna-brown, with two white irregular semi-circular patches, united at the 
dorsal ridge so as to form a broad X-like figure ; pronotal apex pale and blunt; frons 
broad with a white streak above. Suprahumeral processes none; legmina hall- 
concealed ; legs yellow and shining. 
The genus Horiola is very variable in its colouring. 
Size, 4x2 mm.
