Group 3. 



Having disposed of the genera with imperfect acetabula, we here commence the 

 series of typical Lamise, with very elongate forms with short weak legs. The front 

 is long, frequently inflexed : it is channeled between the antennae, which are 

 approximate at base, very long and hairy: the first joint is long and cylindrical. The 

 antennse of the living insect are porrected in front to their full extent. In common 

 with all the Lamiee, as far as group 14, (inclusive,) these genera have the external 

 margin of the anterior acetabula angulated.

 than those of the female.

The two species quoted are from Florida ; they are entirely unknown to me.

Group 4. 



This group contains genera of a narrow cylindrical form, with unarmed thorax. 

 The antennse are very long, (at least in the males), approximate and situated on an 

 elevation, between the eyes the front is deeply channeled. The palpi are long and 

 very slender, the last joint acute at the apex. The last joint of the tarsi is usually as
