Lamellae of the antennae not very long. Thorax very convex, one-fifth broader than long, with a trace of an impression on each side of the disk, rounded anteriorly, parallel at the sides in the middle, very slightly constricted before the diverging posterior angles. The surface is densely and very coarsely punctured and rugulose, except on each side of the base, where it is even and much less coarsely punctured. The punctuation of the elytra (as compared with allied species) is rather strong and very dense at the sides and humeral region. There are no distinct striae except at the base, and two short ones at the side, near the shoulder. The posterior coxae are concave for about half their length. Punctures on the prosternum large and deep, moderately close together, but very irregular. 9. RHYTIDONOTA PLICATA, Kraatz. Nubia. 10. ASPIDOSTERNUM METALLICUM, Fabr. W. Africa. 11.

Loder, F.Z.S., exhibited a tusk of an African Elephant, and made the following remarks :- The Elephant-tusk exhibited this evening is (as far as I can ascertain) the heaviest that has ever been seen in this country. Its weight is 1 cwt. 2 qrs. 16 lbs. = 184 lbs., as will be seen by the accompanying " weight account " signed by the warehouse-keeper of the London and St. Katherine Docks. The length of the tusk along the curve is 9 ft. 5 in., the maximum circumference 22^ inches. It was shipped from Bombay to London, so that it probably came from the east coast of Africa, possibly from Zanzibar. |
