70 INTRODUCTORY REMARKS. 



preceding, is a " rudis indigestaque moles " of Me- 

 littcC and y4pes, taken from all families, each dis- 

 tinguished from the others by peculiarities in its 

 Jnstrumenta ciharia. Thus, Apis seladonia belongs 

 to one family of Melitta ; Apis cunicularia, thora- 

 cica, cineraria, and vestita to another : the exterior 

 palpi of all these consist of six articulations, and 

 by no means agree with the term " hrevissimi (z)," 

 and the interior palpi of four. Apis latipes, vio- 

 lacea, cestuans, pilipes, rotundata, &c. belong to 

 a family of Apes, whose exterior palpi, like those 

 of the preceding, are sexarticulate {a) ; but their 

 interior are only biarticulate (Zj). Apis mellijica 

 and all the true Bomhinatrices, A. terrestris, kor^. 

 torum, &c. have their exterior palpi e?:tremely 

 short ; but, instead of six, they consist only of a 

 single joint (c). The same remark extends to A, 

 manicata (d), which belongs to a subdivision of 

 that family remarkable for its inflected lip. Apis 

 bicornis, tunensis, rufa, &c. enter into another of 

 its subdivisions, the same which includes Andrena 

 carulescens and ainea, distinguished, as above ob- 

 served, by exterior palpi of four articulations. 

 Apis conica, quadridentata, and cent?xncularis ap- 

 pertain to two other branches of the same family,
