None of these insects exhibit any positive colouring of the integument, excepting in some upon the abdomen, which exhibits red bands, and is disposed to vary considerably in intensity and breadth, and in some the clypeus and face are of a cream-colour, but which occurs chiefly among the males. They are very dissimilar in general appearance, some being densely pubescent all over, others merely so on the head and thorax; others are banded with white decumbent down, and some are wholly unmarked upon the abdomen. These peculiarities help to group them, and thus facilitate their recognition.
