ash-coloured scales runs from the shoulders obliquely inwards and backwards, beyond 

 the middle of the elytra. Length 6£ lines ; width 2^ lines. Hab. Moreton Bay. 



P. Jeckelii is rather broader, and less convex than the preceding, has the thorax 

 produced beyond the head, and bilobed in front; the dorsal surface keeled and bitu- 

 berculate, the sides rounded and notched in the middle ; a few very minute granules 

 scattered on the elytra : each elytron with three large obtuse tubercles on the place 

 of the second interstice, two on the fourth, one on the sixth in the middle, and two at 

 the shoulder, besides a transverse irregular elevation at the base; the apex produced 

 into a large tubercle, having a triangular base. Black with minute brown scales, and 

 scattered large scales. Length 6f lines ; width 2f lines. Hab. Moreton Bay. 



Section II. — Antennae with the two basal joints equal, or very nearly so. 



P. Parryi nearly resembles P. Jeckelii, but the tubercles on the elytra are less ob- 

 tuse, and some of them pointed; humeral angles of the elytra more prominent; the 

 thorax with two tubercles in front, and not produced beyond the head ; a very obtuse 

 keel in the middle, and two tubercles (one behind the other) on each side of the keel, 

 besides a lateral tubercle ; elytra each with a sub-apical, dirty white mark, united 

 posteriorly to a small tubercle of the same colour, the scales on other parts brown. 

 Length 1\ lines ; width 3£ lines. Hab. Sydney. In the collection of the British 

 Museum. 



P. Westivoodii, more elongate and more convex than the two preceding species ; 

 thorax produced slightly beyond the head in front, where there are two obtuse tu- 

 bercles ; the central portion with a short keel ; and four tubercles are arranged nearly 

 in a transverse line on the middle of the thorax, the outer pair project horizontally 

 from the sides of the thorax, which, together with the upper surface of the elytra, 

 presents numerous small glossy granules scattered over the surface. Each elytron has 

 five conical tubercles arranged in a line parallel with, and not far from the suture, of 

 which the fourth is very large and prominent, the last (or fifth) small ; besides these 

 are a few other tubercles, of which three may be especially noticed ; they are arranged 

 in an oblique line, extending from the shoulder to the third of the inner row of tu- 

 bercles ; apex of the elytra truncate. Length 1\ lines ; width 2f lines. Hab.

Plagiocorynus, a new genus of the Cryptorhynchida; — first division : founded 

 upon a large Cryptorhynchus, with a general form of the body somewhat like that of 

 Leptops quadrituberculatus. Rostrum very short and stout, and irregularly quadri- 

 carinated above ; thorax large, produced in front into a rounded lobe which projects 

 considerably beyond the head ; elytra of the same width at the base as the thorax, 

 gradually becoming wider towards the hinder part, the sides very deep and bent some- 

 what inwards, the apical portion bent suddenly downwards, with four obtuse tu- 

 bercles in a transverse line, behind the middle ; the base rather deeply trisinuated ; 

 legs short and stout, femora not dentate ; tarsi small ; antenna? with the second joint 

 of funiculus elongate obconic, the first short obconic, the rest very short; club short, 

 and obliquely truncated, the three terminal joints for the most part hidden and en- 

 closed by the basal joint. 



P. quadrituberculatus is black, clothed with dark brown scales; thorax rather 

 coarsely punctured, with a mesial keel and a short keel on each side of the disc; 

 elytra with large punctures arranged in rows. Length 6 lines ; width 3 lines. Hab.
