Lathrobium rujipes, Makl., is certainly identical with punctatum, Zett. ; 
G. Kraatz, Deutsche E. Z. 1876, p. 174 £but it stands, as punctatum is 
preoccupied in the genus by Geoffroy]. 
New genera and species : — 
Scopceodes, D. Sharp, Tr. E. Soc. 1876, p. 208. Between Scopceus and 
Cryptobium, differing from the former in its geniculate antennse and

ibid., and fusciceps, p. 209, Tapajos. 
Sphccronum {Sphcerinum in table, but purposely altered), id. 1. c. p. 224. 
Resembling Ophites in head-structure, but with different mouth-organs, 
sub-geniculate antennaB, and the anterior tibiae dilated at the base and 
suddenly constricted in the middle. S. opacum, p. 225, depressifrons, 
p. 226, carinifrons and elongatum, p. 227, carinicolle, p. 228, xmllidum,

charis; differing from the former in the short robust mandibles, emargin- 
ate and rounded labrura, and structure of the prosternum, and from the 
latter in the bilobed membranaceous fourth tarsal joint. For M. typica, 
p. 272, note, Rio Janeiro, and M. certa, p. 272, longula and divisa, p. 273, 
Amazon Valley. 
Lindus, id. 1. c. p. 281. Facies of iho Finophilides, but with the fourth 
joint of the maxillary palpi concealed, and the pro thorax membranous 
behind the coxae. For L. religans, p. 283, Tapajos.
