placed this species as a synonym of JN. viridula Linn. From that 
species VV. chlorocephala ditfers by its elongate form, and particu- 
larly by its more elongate and narrower head. 
Westwood localized it as “ Brasilia?” The British Museum 
possesses specimens from Nyasaland collected by Mr. A. Whyte. 
NEZARA CHLORIS.

Stal (En. Hem. ii. p. 41, 1872) places this species as a 
synonym of Nezara viridula Linn. In this case, however, he has 
fallen into error. NV. chlovis is a smaller, more elongate, narrower, 
and much more convex species ; the head is large and broad. 
I possess specimens both from Congo and Nyasaland.

Pentatoma africana Westw. in Hope Cat. 1. p. 89 (1837). 
P. frontalis and P. africana are colour varieties. In the strict 
usage of the laws of priority, frontalis is the earliest name; but as 
this is clearly a variety or “sport,” I do not disturb the arrange- 
ment of Dallas and Stal.
