376 Rey. H. Clark on the Halticidee of South America. 
where manuscript names, generic and specific, have been our only 
guiding beacons, and where, moreover, they have faithfully guided 
us. ‘Tradition has a certain real value; if it cannot be compared 
with the precision of written description, certainly it is far better 
than chaos; and in chaos many groups of Coleoptera would have 
been, without the assistance which for many years has been afforded 
by the tradition of Dejean’s Catalogue. 
I ought to mention that Erichson has described (Wieg. Arch. 
1847) among his genera of South American Halticidse two genera 
which I am not able to determine—Patopopa (p. 171) and Ocno- 
scELIs (p. 174); the former of the dipodes of Mlliger, the latter 
nearly related to Asphera and Aspicela of Dej. and of this paper. 
The following list includes all the Dejean genera of South 
American Halticide (edition 3, 1837) :-— 
Ocroconotes (p. 407), with following genera to Dasymatius. See 
British Museum Catal. Halticid., part 1.
