TiiORAXoniORUS, Motsch. {Gli/ptoma, Er.) 



Under this generic name there are mixed in collections 

 and entomological works tAvo distinct genera ; of these, the 

 one to which Ghjptoma crdssicorne, Er., and its allies 

 belong, is allied to Lispinns ; Avhile the other, containing 

 TlwruxopJiorus corticinus, Alotsch., and its allies, is one 

 whose natural affinities are much more obscure to me. Of 

 the two new species here described, one, T. opacus, is 

 allied to G. ci-assicoi-nc, Avhile the other, T. cras-fus, is an 

 ally of T. corticinus. Of these two genera or groups, the 

 one containing G. crassicome is peculiar to South Ame- 

 rica, while the other is found in South America, North 

 America, Europe and East India.
