The specimens brought home by Captain Grey seem to me identical with the above.  Fabricius describes the thorax (truncated in front and rounded behind) as having the anterior margin rufous in the middle, it being wholly of a deep shining black, and as Olivier (l.c.) remarks, the neck or narrowed collar (qui joint la tete au corcelet) is rufous yellow as is the squareish transverse head with a black spot on the crown.  The scutellum and elytra are minutely punctured or chagrined, and hairy (except a small smooth oblong space on the shoulder of the latter) and are black with a violet tinge; in one specimen the elytra have scarcely any of the blue tinge, and the spot on the shoulder is of a ferruginous hue; the wings are violaceous.  Dr. Leach had regarded this as a distinct subgenus, but as the name he had given it is pre-occupied in Botany, and has not been published with or without characters, as far as I am aware, I have not given it.

CRYPTODUS, Macleay.

C. variolosus, Burmeister (Westwood Monograph ined.)

Smaller than Mr. Macleay’s species and of a pitchy brown, it is less depressed; the head is squarer and not so broad, the two tubercles are more prominent, the mentum is deeply emarginate:  antennae nine-jointed; basal joint dilated, prothorax not so transverse, much more closely punctured:  the elytra are scarcely dilated behind, shorter, and are covered with exceeding minute punctures in addition to the larger ones.

Inhabits King George’s Sound, Captain George Grey. (British Museum.)

Mr. Westwood informed me that Professor Burmeister had sent him a description of this species under the above-mentioned name; the characters are the principal of those which will appear in Mr. Westwood’s elaborate memoir.  I had written a description of this species and assigned a name to it, which however I withdraw.  There are more than two species of this curious genus, first published in the Horae Entomologicae.

BRACHYSTERNUS, Guerin. (s.g.  Epichrysus.)

B. ? (E.) Lamprimoides, new species.  Illustration 18 Insects 1.

Viridi aureus, thorace corporeque subtus tomentosis.

Yellowish metallic green, legs darker.  The head is somewhat square, the transverse suture being rather indistinct; the margin of the clypeus is distinctly reflexed.  Antennae dark brown, ten-jointed; 1st joint longest, thickened at the end, with ferruginous hairs behind; 2nd rounded, thin; 3rd, 4th, and 5th, with the separating lines very indistinct, those before the 3 lamellated joints short, transverse.  Maxillary palpi with the terminal joint dilated, rather blunt at the tip, depressed above, and hollowed out at its base.  Legs rather thick, the outer of the two tarsal claws of the third pair of legs, cleft at the end, anterior tibiae externally sub-tridentate.  Thorax with the sides somewhat angulated and narrowly margined, rounded behind, but the sides of the posterior margin are straight, the surface is minutely punctured and covered with brown hairs, the sternum of the mesothorax is without a spine, or projecting angle; elytra in some specimens of a rich, lively, metallic, yellowish green, in other coppery green with the suture and margin dark green, the surface chagreened and punctured.  Underside of the body and legs dark green, the former covered with ash-grey pubescence, or rather longish soft hairs.
