n. 8 (1852). 
A, rhombifer and A. rhombeus are very closely allied and doubt- 
fully distinct. Beyond a generally darker hue and greater ineras- 
sation of the posterior femora in the male of A. rhombeus, there is 
scarcely a character to separate the two forms. 
AMorBUS ANGUSTIOR. (Plate XXIX. fig. 2.) 
Physomerus angustior Westw. in Hope Cat. il. p. 9 (1842). 
This species can be separated from A. obscuricornis Westw., 
to which it is closely allied, by the colour of the posterior 
tibix. Dr. Mayr (Reise Novara, Hem. pp. 86-7) separates the 
species by the colour of the antenna, and by the presence or 
absence of a small black apical spot on the red upper surface of 
the abdomen. These characters are, however, both inconstant, and 
this distinetlion cannot be maintained. Westwood omitted to 
describe the colour of the posterior tibiae in his A. angustior, but 
the unique type is now figured. 
AMORBUS SUBSERRATUS. (Plate X XIX. fig. 5.) 
Physomerus subserratus Westw. 
The only really distinguishing feature of this species from the 
above is found in the character described by Westwood as ‘“ tibiis- 
que pone angulum medium marginis interni 4-serratis.”
