The genera referred to six of these gToups are as follows : — Blissida — 
BUssus (lOug), Boehms, and Papirius (StSl) ; Lygjeida — Lygeeus (Fab.), 
Astacops (Boisd.), and Nysius (Dali.) ; Geocorida — Geocoris (Fall.), Henes- 
taris (Spin.), Ninus, Germalus, and Hcemus (StRl) ; Pachygronthida — 
Pavhygrontha (Germ.), CEdancala (Am. & Serv.), Tei'acrius and Phlegyas 
(StEl) ; Cymida — Cymodema (Spin.) and Oxycarenus (Fieb.); Bhypa- 
ROCHROMiDA — CUrada (Sign.), Myodocha (Latr.), Cnemodus (H.-Sch.), 
Plociomera (Say), Beosus (Am. & Serv.), Lethceus (Dali.), Herceus, Fontejus, 
Gyndes (StRl), and three new genera. The other subfamilies are not 
noticed, 
Lygeeus. Mayr (Reise der Novara, Zool. ii. Hem. pp. 123-126) proposes a 
division of this genus into 8 groups, under each of which he cites the species 
belonging to it with which he is acquainted. He also remarks upon the 
characters and synonymy of some of the species, such as L. elatus (StSl), 
pallidocijictus (StSl), turcicus (Fdh.'), fasciatus (Dali.), and (Fab.). 
Ccenocoris nicoharensis (Mayr) is figured by Mayr, 1. c, Taf. 3. fig. 30. 
Ajihanus clavatus (Dali.) = Plociomera nodosa (Say) and Phypar. cephalotes 
(Dali.) belongs to Gyndes (StM). See StSl, B. e. Z. 1866, p. 161. 
Cnetnodus brevipennis (H.-Sch.) = Astemma mavortia (Say). See StSl, 
ibid. 
Lygeeus maculicolUs (Germ.) = L. rubricosus (StSl). StSl, 1. c. p. 162. 
Tetralaccus. Alydus marginatus (Thunb.) is characterized and referred to 
this genus by StSl = Serinetha sinee (St^l). Berl. ent. Zeits. 1866, p. 163. 
Pendidinus uniguttatus and guttatus (Thunb.) = Beosus uniguttatus (St§,l) ; 
Cimex caffer (Thunb.) is also a Beosus and s= Phyp. pedestris (Panz.). Still, 
I, c. p. 382. 
Beosus cnjfer (StHI) changed to B. mendicus. Stal, Hem. Afr. iv.-p. 266.
