 Cafdines. These intervene bettveerl the valvulae 

 ,and the lora, and seem to perform the office of 

 hinges. They are mentioned by Swammerdam, 

 as means, in conjunction with the fulcrum, by 

 which the proboscis is united to the head. Reau- 

 mur terms them ^'^fiUts tendineux par les quels les- 

 ti^es sont attachSes a leurs appuis (z) ." 



Palpi exteriores. These are not noticed by 

 Swammerdam, though his figure of the proboscis 

 of the hive bee gives a rude sketch of them at </. 

 By Reaumur they have been entirely overlooked 

 not only in A. mellificaf in vvhich they are very 

 minute and consist only of a single joint, but like- 

 wise in A. violacea, where they are very easily seen 

 and are sexarticulate. In his genus ProaheUle he 

 notices them, but there confounds them with the 

 apex of the valvulae (a). De Geer denominates 

 them ^^ les grands barbillons [b) ." 



Palpi interiores. These are called by Swam- 

 merdam " the two upper articulations of the second 

 pair of joints of the proboscis [c)" Reaumur dis- 

 tinguishes them by the term " barbes" but he did 

 not examine them so closely as might have been 

 expected, for in his account of the proboscis of 

 A. mellifca he represents them as consisting of 

 from three to four articulations (c?), when, in fact, 

 they have only two. - His figures sometimes repre-
