80 HEMIPTERA-HOMOPTERA. 
Hab. Guatemata! (coll. Signoret, in Mus. Vind. Ces.). 
This species is not represented in our collection. 
The Ceresa-like form, the round dark spot on each side of the pronotum, and the long 
dark band on the exterior portion of the tegmina will at once distinguish 7. vittatipennis.

Chiriqui 2000 to 3000 feet (Champion).—Brazi!. 
I am indebted to Dr. Goding for the identification of this species. I have not had 
an opportunity of examining a typical specimen of C. prasina myself; the differences 
between the various species seem somewhat obscure, and cannot be made out satis- 
factorily from the descriptions. C. prasina externally resembles C. vaginata, Germ. 
(campestris, Fairm.), of which there are specimens in the British Museum, but it is less 
strongly sculptured. A specimen from Cubilguitz is figured. 
NASSUNIA. 
Nassunia, Stal, Kongl. Sv. Vet.-Ak. Handl. Band iii. 2, p. 30 (1860). 
This genus is closely allied to Smiliorachis, from which it differs in having the 
shoulders armed with a sharp spine on each side, thus resembling Ceresa; from the 
latter genus, however, it may be at once known by the oblong and parallel apical areas, 
and the single small discoidal area of the tegmina. 
1. Nassunia bispina. (Tab. VI. figg. 12, 12a, 3.) 
Smiliorachis bispina, Fairm. Ann. Soc. Ent. Fr. sér. 2, iv. p. 290°. 
Hab. Panama, Bugaba (Champion).—Co.tomBia! (Mus. Roy. Belg.). 
We have received two specimens of this species from Chiriqui.
