I have not adopted the arrangement of the subfamilies followed by Stal and some 
other authors, as it seems preferable to begin the group with the Membracine rather 
than with the Tragopine as they have done; as a matter of fact, the question is one of 
small importance at present, as the affinities of the groups are as yet but imperfectly 
understood. 
Subfam. MEMBRACINA. 
The following table will serve to distinguish roughly the genera belonging to this 
subfamily which are mentioned below, but these dichotomous tables are always more 
or less unsatisfactory, and the full description should always be referred to:— _ 
I. Pronotum very strongly foliaceous, much elevated, rounded in 
front, and without anterior process. . . . . . . . . Membracis, Fabr. 
II. Pronotum ‘moderately or slightly foliaceous or strongly com- 
presso-elevate, nearly always with a longer or shorter horn in 
front, and at all events obtusely angled, and not broadly 
rounded. 
1. Lateral carinew of pronotum not or scarcely extended beyond — 
humeral angles. . . . . 2 ee ew ee )6Enchophyllum, Arm. et Serv. 
. Lateral carine of pronotum extended beyond humeral angles, 
and usually reaching the hinder lateral margins . . . . Enchenopa, Am. et Serv. p. ‘6 
III. Pronotum not foliaceous or compresso-elevate. 
1. Head three-lobed; pronotum with clavate or fungiform 
~ processes, variable in form. . . . 1... + . _ Sphongophorus, Fairm.
