Ifi] INTRODUCTORY REMARKS, 



and left out the fifth. The Perce-hois he calls 

 MenuisiereSy and the Bourdons, Cardeuses [x) . 



Linneus's characters of this genus, as they stand 

 in the last edition of the Sy sterna Naturce, are these J 



APIS. Character Essentialis. 



Aculeus punctorius : lingua inflexa. 



Character Artificialis. 



Os maxillis atque proboscide inflexa, vagi- 

 nis duabus bivalvibus. 



u4la^ planas in omni sexu. 



jiculeus feminis et neutris punctorius, re- 

 conditus. 

 This character will exclude more than half those 

 insects which Linneus arid many other authors 

 have regarded as belonging to this genus, and at 

 the same time admit Sphex sahulosa and its con- 

 geners, {Ammophila, K.) for the proboscis of the 

 former, when not exerted, instead of being in- 

 flected, points to the maxillae, and the terms, 

 '^ Proboscide infexd vaginis duabus bivalvibus," 

 will apply to the latter with stricter propriety than 

 to most genuine ^pes ; for in these, the Nomado' 

 excepted and another small family (?/), one of the 

 two vagintF, if we may denominate it by that term, 

 is in fact quaclrivalvis (z).
