The larvae are of the usual cylindrical form, attenuated at the extremities, and of a dull white colour, about ½ an inch in length, and can be found in all stages of development in November. The pretty banded bees, formerly known under the name of _Anthophora_, but now placed in the Genus _Podalirius_, are world wide in their range. All our species have the head and thorax clothed with a dense coat of buff or pale yellow hairs, and the body banded with black and blue of various tints. _Podalirius emendatus_, our largest species, is found on the northern rivers of N.S. Wales and is common in Queensland; it has the head and thorax covered with rusty red pubescence, and the low abdominal bands broad. _P. cingulatus_ is slightly smaller, with the pubescence pale buff, the abdominal bands much the same; _P. pulcher_, much smaller, with the pubescence darker, is our commonest species about Sydney. _P. aeruginosus_ has the whole of the abdomen as well as the head and thorax thickly clothed with a dull greenish yellow pubescence. My specimens of this species come from Mackay, Queensland. Five new species are added to this genus by Cockerell. The Genus _Crocisa_ contains a few very handsome moderate sized bees of a uniform black colour with smoky rings, and brightly marked bodies. _Crocisa albo-maculata_, our largest species, has the face, upper and under surface, and legs thickly marked and spotted with white pubescence. It is a somewhat rare insect about Sydney. _C. lamprosoma_ is a smaller bee with the marks and spots pale blue, those upon the abdomen forming a more regular pattern of four well defined rows. In _C. nitidula_ the pubescence forms rich metallic blue spots and blotches, most brilliant on the upper surface of the abdomen, where they run right round the basal segment and form a regular row of short bands on either side but not meeting on the dorsal surface. It is found in New South Wales and Queensland. [Illustration: Plate XVI.--HYMENOPTERA.
