STATES OF INSECTS. 387 



led to conjecture that, like the supposed Clavarice that 

 were imagined to grow on some humble-bees, but which 

 are now ascertained to be the anthers of flowers — these 

 also belong to the kingdom of Flora, and are spoils which 

 the bee in question has filched from the blossom of some 

 plant. The individuals that have been thus circum- 

 stanced are males ; whether the female is guilty of simi- 

 lar spoliations is not known. In my specimen there are 

 no traces of them. In many bees, the first joint of the 

 posterior tarsi is much larger in the females and workers 

 than in the males; but in the hive-bee this joint is larg- 

 est in the latter a . In Beris clavipes and Empis nigra, 

 two flies, the joint in question is large and thick in the 

 male, but slender in the female. The penultimate tarsal 

 joint in the posterior legs is dilated internally, and termi- 

 nates in a mucro in one sex of Anoplognathus Dj/tiscoi- 

 des of Mr. W. MacLeay b . In some insects the anterior 

 tarsus of the males has been supposed to be altogether 

 wanting : I allude to the petalocerous genus Onitis F. ; 

 but I have a specimen of Onitis Apelles of this sex, or a 

 species nearly related to it, in which one of these tarsi 

 is to be found c ; which, though very slender, consists of 

 five joints, and is armed with a double claw : from which 

 circumstance it may, I think, be concluded, that although, 

 as in Phanceus, these tarsi are very minute, they are not 

 wanting. What renders this more probable is, a circum- 

 stance which every collector of insects, who has many 

 specimens of Mr. W. MacLeay's Scarabceidce in his ca» 

 binet, must have noticed : namely, that in all, except Co-
