INTRODUCTORY REMy^-RKS. 35 



J^us albipes and its affinities, the tongue of these 

 being that of his genus Andrena. 



ANDRENA. Antcnnes filifory^. Langue ob- 

 longue ; division du milieu en 

 point refendue. 



This genus would include all my families of JSIc- 

 Utta but the first and second. The character is 

 extremely accurate, but the point of the interme- 

 diate division of the toncjue is lacerate rather than 

 cleft (c). 



8. Fam. 11. Langue tres-prolongee, ttroite, 

 lineaire, presque cylindrique, un peu coriacee, a 

 papilles vers I'extremite, flechie a la sortie de la 

 gaine. Machoires ilechies. Antennules anteri- 

 eurs tres-courtes, presque obsoletes, setacees. 



That part of this character which regards the 

 exterior palpi is not accurate, for in the true No- 

 madcPy the Eucene, and two other of my families 

 of genuine Apes, these are as long as in the ?de- 

 littie of the preceding family, and consist of six 

 joints (f/). He probably took his idea of them 

 from Apis mellijica, or the Bomb inatr ices. Here 

 are arranged the remaining genera which Fabricius 

 separated from Apis : viz. Nomadaj Apis, and 

 ^ucera.
