Physomerus rhombifer Westw. in Hope Cat. ii. p. 9 (1842). Amorbus rhombeus Dall. (nee Westw.) List Hem. ii. p. 411. n. 7 (1852). AMORBUS BHOMBETJS. Physomerus rhombeus Westw. in Hope Cat. ii. p. 10 (1842). Amorbus rhombifer Dall. (nee Westw.) List Hem. ii. p. 411. n. 8 (1852). A. rhombifer and A. rhombeus are very closely allied and doubtfully distinct. Beyond a generally darker hue and greater incras-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. ii. p. 9 (1842). This species can be separated from A. obscuricornis Westw., to which it is closely allied, by the colour of the posterior tibia?. 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 distinctlion cannot be maintained. Westwood omitted to describe the colour of the posterior tibia? in his A. angustior, but the unique type is now figured. AMORBUS SUBSERRATUS. (Plate XXIX. 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." Subfam.
