families of Coleoptera, to exclude such forms as Hypo- 

 cephalus, Parandra, &c., from the Longicorns. 



Of M. Lacordaire-s second legion " Prionides vrais," 

 we have only to do with his second " Cohorte/' the 

 " Prionides vrais sylvains" no example of " Prionides vrais 

 souterrains" being contained in Mr. Wallace's collection. 

 We find twenty-seven subfamilies {groupes) in the two 

 " Sections " into which this cohort is divided, and of 

 these nine only are represented. These are set out 

 below after M. Lacordaire's tables, which, it is necessary 

 to remark, are entirely taken from the characters of the 

 male. 



Episterna of the metathorax parallel, truncate behind. 



Sides of the prothorax armed with sj^iues .... Deeobrachin^. 



Sides of the prothorax not armed with spines, denti- 

 culate or creuulate. 



Labium bilobed Ctenoscelin^. 



Labium entire. 



Tarsi with the third joint bilobed. 



Antennae with the basal joint shorter than the 

 third. 



Tibise unarmed Zaeacin^. 



Tibiae spinous Macrotomin^. 



Antennfe with the basal joint as long as the 

 third. 



Tibiae spinous Eemphanin^. 



Tibiffi unarmed Mallodontin^. 



Tarsi with the third joint entire CoLPODEEiNiE. 



Episterna of the metathorax gradually narrower and 

 acimiinate behind. 



Pronotum distinct from the flanks of the prothorax Closteeik-s;. 



Pronotum partly confounded with the flanks . . iEGOsoMATiN^. 



DEEOBRACHINiE. 



The new and only genus representing this subfamily 

 in the collection, is also the only one not a native of 

 America, but the Acanthophorince, to which it is nearly 

 allied, are African and Indian. The character differen- 

 tiating it from the latter, lies in the fine longitudinal 

 grooves on the joints of the antennas.
