Besides the typical genera the first of these groups includes Calodromus 
(Gu6r.), Zemioses (Pasc.), Cypliayogus (Parry), and ? Aprostoma (Gu^r.) ; the 
third, Cerohates (Schonh.), Molispa (Pasc.), CordniSj AmorphoccphahiSj Sym- 
morphoccriis (Schonh.), and ? Diadrophus (Porroud) ; tlio fburtli, Onychodes 
(Pasc.); the sixtli, Clccodcres and Caph(doburus (Schonh.); the sovontli, 
llhyticcphaluSf llormocerus (Schonh.), Uroptevus (Lat.), Bhuciccrus (Schiiiih.), 
and Temnolaimus (Chevr.) ; the tenth, Ectoceimis (Pasc.) and Raphirhyn- 
chus (Schonh.); and the twelfth, Teramocerus (Schonh.), Ozodecencs (Chevr.). 
and Prodectus and Purus (Pasc.). The other groups contain only the typical 
genus, with or without new genera ; most of those above referred to include 
new genera, which will be cited hereafter.
