mostly gold-green or purple-red, sometimes blue, just as the head 
and thorax usually are), and which have caused them to be compared 
with humming-birds. 
The first joint of the antenne is elongate ; at the second joint 
they are bent geniculately. The females lay their eggs in the nests 
of other hymenoptera, whose larve are eaten by theirs. These 
insects are protected from the sting of bees and other hymenoptera, 
their natural enemies, by their hard integument ; and besides this, 
they have the power of bending the abdomen under towards the 
thorax, and so, like the Armadillos amongst the mammalia, of 
contracting themselves into a ball. They form the transition 
between the first and second divisions, and are joined to the first, 
that of the aculeata, by Hartic, because they are without the part 
which he considers to be a second trochanter.
