192 HEMIPTERA-HOMOPTERA. 
CEPHISUS. 
Cephisus, Stal, Hemipt. Afr. iv. p.67 (1866) ; Berl. ent. Zeitschr. x. p. 384; Hemipt. Fabr. ii. p. 18. 
Aphrophora, Walker, List of Homopt. Ins. iii. p. 697 (ex parte). 
So far as regards the structure of the wings this genus is closely allied to Aphro- 
phora, from which it differs in the shorter rostrum and the absence of a carina on the 
vertex of the head, as well as in the larger size of the species.

This large species, which is widely distributed in Central and South America, appears 
to have been always identified with Aphrophora siccifolia, Walk., recorded by him as 
from West Africa; possibly there is a mistake as to Walker's locality. 
A specimen from Chilpancingo is figured. 
LEPYRONIA. 
Lepyronia, Amyot et Serville, Hist. Nat. des Ins. Hémipt. p. 567 (1843) ; Stal, Stett. ent. Zeit. 
1864, p. 67. 
Amyot and Serville distinguish this genus as having the body “ court et ramassé,” 
and the “ élytres bombées, en ovale court et en forme de coquille”; a better distinction, 
however, is to be found, according to Stal, in the fact that the submarginal vein of the 
wings is more or less widely interrupted at the apex, and the wings at rest form a fold 
at this point: this is very plain in the larger species, such as L. subfasciata, from 
Brazil, of which a tegmen and wing are figured (Tab. XII. figg. 4, 4 a).
