In this tribe are included a few myrmecophilous genera (Colovo- 
cera, Reitteria, Displotera, and Merophysia) which have not as yet 
been met with in South Africa. It is, however, probable that 
representatives of this remarkable little group, which is charac- 
terised by eight-jomted antenne, the club of which is formed by the 
ultimate joint only, will be discovered eventually there in ants’ nests. 
For the present one genus Holoparamecus and one species only 
is known to represent the tribe in South Africa. 
Gen. HOLOPARAMECUS, Curt., 
Entom. Magaz., i., 1833, p. 186. 
Body oblong, slightly convex ; antennee inserted under the margin 
of the anterior angles of the frontal part, number of joints varying 
from nine to eleven, two apical ones forming an oval, rather stout 
club; eyes rounded, lateral; prothorax cordiform and varying in 
sculpture at middle before the base; scutellum transverse, very 
distinct ; elytra with a thin juxta-sutural stria (except the sub-gen. 
Tomyrium). 
The number of antennal joints varying in some species, and even 
according to sexes, the genus has been divided in four sub-genera.
