HABITAT: Cayenne.

Entirely black. Head rounded in front and margined; armed with a long horn that inclines towards the body, the inner part of which, near the top, is dentated. Thorax terminating at the corners, next the body, in two projections like horns, extending in an horizontal position, being very obtuse, and wider at the ends than the middle. The central part has two small projections which are bifid, and two dents on the middle of the posterior margin. Scutellum not distinct. Elytra deeply furrowed. Legs thick and strong. Fore and hinder tibiæ dentated.

{74}RHIPICERA DRURÆI.

ORDER: Coleoptera. SECTION: Serricornes. FAMILY: Cebrionidæ.

GENUS. RHIPICERA, Latr. Kirby. Hispa, Fabr. Drury. Ptilinus, Fabr. Polytomus, Dalman. Ptiocerus, Hoffmansegg.

RHIPICERA DRURÆI. Thorace griseo sericeo; elytris brunneis albo-punctatis scutelloque albido, pedibus supra fuscis subtus griseis. (Long. Corp. 7½ lin.)

HABITAT: "Sierra Leone, Mr. Smeathman, 1776" (Drury's MSS.).

Head small, black, thin, and margined from the part where the antennæ are placed; but behind them to the thorax growing suddenly thick and round. Antennæ strongly pectinated, each ramification increasing from the base towards the middle, and then gradually decreasing in length; they are about a third part of the insect's length, and entirely black. Thorax grey, rounded, having a ridge on each side, and seeming covered with a fine pile or down. Scutellum grey and round, appearing like a whiteish spot. Elytra dark red-brown, covered with a multitude of small whiteish spots, furrowed and margined at the sides and suture. Breast and abdomen grey, each ring of the latter having some black spots on it. Legs brown above, grey beneath.

I have attached a mark of doubt to all the synonyms quoted above, 1st. on account of the difference of locality between Drury's Insect, and that described by Fabricius, which is from New Holland. 2ndly. Because Drury's description does not agree with the true Rh. mystacina: and 3dly. because as there is another spotted species of the genus found in North America, described by Laporte, it is most probable that Drury's insect is altogether distinct, in which case I have proposed for it the name of Rhipicera Druræi. Mr. Kirby speaks of the New Holland species of this genus as though there were more than one, and he has described one from that country under the name of R. femorata, in the 12th volume of the Linn. Trans. No. 9. in which the thorax, as well as the elytra, is spotted with white, whereas the thorax of Mystacina is described by Fabricius as being "cinereus." The Rh. mystacina of Laporte entirely agrees with Mr. Kirby's Rh. femorata. The Rh. femorata of Dalman is a totally distinct species from Brazil, and as it is necessary that a new specific name should be given to it, I would suggest that it should be termed Rh. Dalmanni.

SAPERDA SPECTABILIS.

HABITAT: Bay of Honduras.

{75}Head black, with a large yellowish spot between the eyes. Antennæ black, and almost the length of the insect, having a row of short hairs running along the under side. Thorax black beneath, lemon-coloured above, with three black spots. Scutellum small, triangular, and black. Elytra black, with two broad straw-coloured bars crossing them, each having a spine at the extremity near the suture. Beneath black, except the middle of the abdominal rings, which is grey.
