336 STATES OF INSECTS. (Jmago.) 
led to conjecture that, like the supposed Clavarie 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 
largest in the latter. In Beris clavipes and Empis chio- 
ptera®, two flies, the joint in question is large and thick 
in the male, but slender in the female. The penulti- 
mate tarsal joint in the posterior legs is dilated inter- 
nally, and terminates in a mucro in one sex of Anoplog- 
nathus Dytiscoides of Mr. W. MacLeay*. In some in- 
sects the anterior tarsus of the males has been supposed 
to be altogether wanting: I allude to the petalocerous 
genus Onitis ; 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‘; which, though very slen- 
der, consists of five joints, and is armed with a double 
claw: from which circumstance it may, I think, be con- 
cluded, that although, as in Phaneus, these tarsi are 
very minute, they are not wanting. What renders this 
more probable is, a circumstance which every collector 
of insects, who has many specimens of Mr. W. Mac-
