This genus is closely allied to Zragopa, from which it differs in having about half 
the tegmina free and with much smaller margins. Horiola proper only contains 
one or two very variable species; it has, however, been increased by the addition of 
species belonging to Micrutalis, such as Horiola discalis, Walk. (List Homopt. Ins., 
Suppl. p. 154), &c.

This species is very variable, but the series from Bugaba appears in great measure 
to set at rest the question of synonymy, for the specimens vary very much in colour 
and size, and among them are examples which answer to typical specimens of 
H. glabrata (picta) as well as of H. arcuata. A specimen from Bugaba is figured. 
In the Royal Belgian Museum there is a very fine male specimen of H. picta labelled 
“ Florata,” ‘“‘ La Cigale Fleurie de Surinam ” (cf. Stoll, Cigales, t. 16. fig. 89). | 
Subfam. SMILIINA. 
The Smiliinz may be distinguished from the Darnine by having the third apical cell 
of the tegmina stylate or petiolate, with the adjacent cells contiguous to one another. 
The shape of the third apical cell is usually subtriangular, but in some instances, as in 
Hypamastris, it is semicircular, and the vein forming its stalk bisects the base of the 
arc. Stal separates the subfamily from the Tragopine, as already stated, on the ground 
that the tegmina are entirely membranous; but this is not correct, as in many species 
the external margin towards the base is coriaceous. The subjoined table (pp. 87-90) 
will serve roughly to distinguish the genera, but it must be regarded as simply an 
aid to their identification, and will probably break down in certain points when fresh 
genera and species are discovered, in the same way that I have found Stal’s tables 
break down in some cases; in fact I should much prefer to leave the tables out 
altogether, if it were not for the fact that, in spite of their necessary imperfections, 
they are often of great service to students as “ sign-posts.””
