SMILIIN A. 87 
It might, perhaps, be of advantage to divide this subfamily into groups, but it would 
be hard to define where they begin and end. Dr. Goding (Trans. Am. Ent. Soc. xix. 
pp. 253 et seg.) forms four tribes—Cerasini, Polyglyptini, Smiliini, and Telamonini ; 
but the Cerasini might, with reason, be further subdivided into three—Cyphoniini, 
Cerasini, and Acutalini; and the Polyglyptini lead directly into the Smiliini through a 
new genus Polyglyptodes. 
I. Tegmina free, with the clavus uncovered, its interior margin touching 
the external margin of the posterior process of the pronotum. 
1. Corium with two contiguous veins (presenting the appearance of 
one vein {) proceeding from the base, dividing and forming an 
oval area at a short distance from the base.

inflated behind, terminating in a single long spine ;

obtuse atthe apex . . . . . ... . . . . Stictocephala, Stal. 
2. Corium with two distinct and not contiguous veius proceeding 
from or from near the base ; the ulnar vein dividing and forming 
an oval area at a short distance from tle base; size small. _

B. Corium with two discoidal areas; upper surface shining . . uritea, Stal. 
+ This contiguous double, or in some cases apparently single, vein, which proceeds from the extreme base and 
soon divides, is perhaps best regarded as the ulnar vein in all cases ; the radial vein may then be regarded as 
either wanting or present, and this will form the basis of a clear division: the meaning of this will be evident 
if the tegmina of Cyphonia and Antianthe (v. p. 89 nota), for example, be compared.
