stigma, it likewise agrees ; and the fruit is also a berry, seated 
on the persistent cupular base of the calyx. 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 ; 
for it is very probable that its flowers may occasionally he ab- 
normally pentamerous. I add below, in a note, my observations 
upon the above-mentioned plant*. 
III.—On certain Musical Curculionide ; with Descriptions of 
two new Plinthi. By T. Vernon Woxt.aston, M.A., F.LS. 
Wuitst 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 (1 believe the A. argillosus, 
Schénh.), 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) brought 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
