PIEZODORUS. 
Piezodorus, Fieber, Eur. Hem. pp. 78 et 829 (1861) ; Stal, En. Hem. v. p. 66 (1876). 
Nezara (part.), Stal, Hem. Afr. i. p. 192 (1864) ; Ofv. Vet.-Ak. Férh. 1867, p. 530. 
The best differential characters amongst those enumerated by Stal are, perhaps, 
“carina mesosterni anterius distinctius elevata, ibidem incrassata, vel plerumque lami- 
nata, plerumque quoque inter coxas anticas libere prominula.” This genus has an 
extremely wide range, although the species it contains are few in comparison. It is 
recorded from the Neotropical, Ethiopian, Palearctic, Oriental, and Australian Regions ; 
and one species, P. lituratus, Fabr., is somewhat common in England.

A Guatemalan specimen is figured. 
PHINEUS. 
Phineus, Stal, Stett. ent. Zeit. xxiii. p. 97 (1862) ; Ofv. Vet.-Ak. Férh. 1867, p. 530. 
The head is short, and toothed on each side at the base, a character alone sufficient 
to differentiate it here. But one species is at present recorded, and that only from 
Mexico. 
1. Phineus fusco-punctatus. (Tab. VIL fig. 8.) 
Phineus fusco-punctatus, Stal, Stett. ent. Zeit. xxiii. p. 97.52"; En. Hem. ii. p. 46.1’.

The specimen figured is a typical one belonging to the collection of Dr. Signoret. 
TAUROCERUS. 
Taurocerus, Amyot et Serville, Hist. des Hém. p. 151 (1843); Dallas, List Hem. i. p. 197. 40 (1851) 
Stal, Ofv. Vet.-Ak. Forh. 1867, p. 531. . 
Canoca, Walker, Cat. Het. ii. p. 404 (1867). 
The second joint of the antenne is longer than the first, which does not reach the 
apex of the head; the posterior angles of the sixth segment of the abdomen are acutely 
produced ; the tibie are not sulcated; and the lateral angles of the pronotum are much 
produced. Taurocerus is confined to the Neotropical Region; three species are known, 
and all occur in this fauna. 
1. Taurocerus achilles. (Tab. VII. fig. 24.) 
Taurocerus achilles, Stal, Stett. ent. Zeit. xxiii. p. 108. 92'; En. Hem. ii. p. 46. 1’.
