_Hylaeoides concinnus_ is a very remarkable looking black bee, with clouded smoky wings, marked with bright red on the face, and with bands of the same colour on the base and tip of the abdomen. I have usually captured this bee upon bushes; it bears such a decided superficial resemblance to a small clay nesting (_Odynerus_) wasp, that this may be a case of protective mimicry. The Genus _Paracolletes_ has been added to by Cockerell, who describes twelve new species in his recent papers. _Paracolletes crassipes_ was described by Smith from W. Australia, but it is common on low scrub in the early part of the year on the Blue Mountains N.S.W. It is a handsome black bee about ½ an inch in length, with the head and thorax thickly clothed with pale buff hairs, and the abdominal segments banded on the upper surface with dull brown. _Gastropsis (Oestropsis) pubescens_ is nearly as large as a honey bee, with curious thickened antennae, slender at the basal joint. It is somewhat flattened on the upper surface and clothed all over with a dense coat of pale buff coloured hairs, only showing indistinct brown bars on the abdomen. I know nothing about the habits of this curious bee; it has been described from Western and South Australia. The Genus _Halictus_ is represented by about thirty described species; nothing has been recorded about the habits of our species, but most of the European form galleries in the ground connected with a large excavation or chamber in which the larvae are placed in cells. _Halictus floralis_ is a small bee with a reddish brown body; the front of the head, antennae, legs, front and middle of thorax are light yellow. _H. bicingulatus_ is black with the legs reddish brown, and the segmental divisions of the abdomen light coloured. They are found on grass and field flowers. _Nomia australica_, under ½ an inch in length, is common on the flowers of the _Leptospermum_; it is a dull, metallic blue bee with antennae, labrum, legs, and extreme tip of abdomen reddish brown. The latter has a greenish sheen, and is somewhat heart shaped, terminating in a fine point. Cockerell has added six new species to our list, most of which are described from Queensland.
