In its general habit it quite resembles other species of Condalia, its leaves being alternate, and it has no spines. Dr. Philippi describes its flowers as being pentamerous ; but in the specimen I examined they were certainly tetramerous, as in the other species of the genus. I do not doubt the accuracy of the former statement j for it is very probable that its flowers may occasionally be ab-normally pentamerous. I add below, in a note, my observations upon the above-mentioned plant*. III. — On certain Musical Curculionidse ; with Descriptions of two new Plinthi. By T. Vernon Wollaston, M.A., F.L.S. Whilst residing in the remote and almost inaccessible village of Taganana (towards Point Anaga), in the north of Teneriffe, during the spring of 1859, my attention was called to a pecu-liarity in a beautiful species of Acalles (I believe the A. argillosus, Schonh.), which I do not remember to have seen recorded con-cerning any other Coleopterous insect whatsoever. It was on the 22nd of May that my Portuguese servant (whom I had sent out to collect) Drought me home eleven specimens of a large Acalles which he had captured within the dried and hollow stems of a plant growing on the rocky slopes towards the sea, and which I have but little doubt (from his description) was the Kleinia neriifolia, DC, so common throughout the islands of the Canarian archipelago. I had been accustomed to find such a number of insects in the dead branches of the various Euphor-bias, that my attendant also had discovered, from time to time, the locus quo of many a rarity by imitating my method of .re-search ; and, to use his own expression, he was about, in this instance, to throw away these rotten stems as worthless, when he was arrested by a loud grating, or almost chirping, noise, as * Condalia Maytenoides; — Sciadophila Maytenoides, Phil.
