Pelogonid^e. 
A single species of this family, P. marginatus (Lat.) = P. caffer (Stdl), is 
described by StSl, Hem. Afr. iii. p. 171. 
Galgulidas. 
Of his family Mononychida StSl (Plem. Afr. iii. pp. 171-172) tabulates 
4 genera, namely, Mononyx (Lap.), Phintius and Matinus (Stal), and Pelto- 
pterus (Guer.) = Scyloecus (StSl). Of the second and fourth of these genera 
he describes single species as belonging to the African fauna. 
Nepid^e. 
The insects of this group are referred by Stal (Hem. 
Afr. iii.) to 3 families, namely Naucorida, Belostomatiday and 
Nepida. Of the first he tabulates 8 genera, 4 of which have 
African representatives, namely IlyocoriSy MacrocoriSy Naucorisy 
and Laccocoris'y the second includes 11 genera, 4 African, 
Limnogetoriy Hydrocyriusy Belostomay and Appasus) Serphus 
(Stal) midi Abedus (StSl) have uniunguiculate anterior tarsi; 
and of the third 7 genera are tabulated, 3 of which, namely 
Ranatra and two new ones, include African species. Borhoro- 
treplies (Stal) = Limnogeton (Mayr) ; and Ilyotrephes (Stal) 
— Hydrocyrius (Spin.). 
Cryphocricus (Sign.). Mayr (Reise der Novara, Zool. ii. Hem. p. 182) dis- 
cusses the characters of this genus, which he regards as uniting Aplielocheirus 
with Naucoris, so that, he thinks, the family distinction must be given up. 
Ranatra. Mayr (/. c. pp. 189-190) enumerates the described species of this 
genus, and discusses their characters, arranging them in groups founded on 
the presence of one or two teeth on the anterior femora, or their total absence. 
He figures the metasternum of R. elongata (Fab.), tab. 5. fig. 58, and also 
R. chinensis (Mayr), fig. 59, and R. {Cercotmetus) parmata (INIayr), fig. 60. 
Ranatra linearis. The pupa of this species was foimd in mud in the spring 
of 1866. Douglas, Ent» M. Mag. iii. p. 25.
