Show 124 MR. A. BOUCARD ON THE GENUS PLUSIOTIS. [Mar. 2, I have the greatest pleasure in dedicating this species to my intimate friend M . Auguste Salle, in honour of his numerous entomological discoveries in St. Domingo, Central America, Mexico, &c. PLUSIOTIS LANIVENTRIS, Sturm, I. c. p. 339, t. 3. f. 5. P. laniventris : oblonga, ovata, supra leete viridis ; capite, thorace elytrisque crebre punctulatis, margine cupreo-micanti; infra viridi-aurata, tibiis tarsisque aureis, antennis rufis. Length 1 inch 3 lines. In Dr. Gemminger and B. de Harold's ' Catalogus Coleopterum,' P. latipennis oi Sturm and P. ser ena oi Klug are regarded as synonyms of this species. * I have two specimens of this rare insect, which is also in the collections of M M . de Mnizech and Salle. PLUSIOTIS MNIZECHII, sp. n. P. mnizechii: oblonga, convexa, supra leete viridis, capite punctato, oculorum margine interiore aureo, clypeo antice rotundato roseo-violaceo ; thorace crebre punctulato, margine aureo ; elytris fortiter punctulatis, margine aureo-micanti, scutello cupreo ; infra viridi-cuprea; femoribus, tibiis tarsisque aureis, antennis fuscis. Length 1 inch 4 lines. Head, thorax, and elytra strongly punctured, with a brilliant gold margin and suture ; clypeus rufous, with purple reflections; thorax, elytra, and pygidium golden green; scutellum coppery, underside copperish green ; legs, tibiae, and tarsi golden ; antennae rufous. Hal. Mexico. I have two specimens of this handsome species; and I have seen two others in the British Museum which seem to be similar. I do not know of any other specimen. I dedicate this fine insect to m y honourable friend Count Georges de Mnizech, in honour of the magnificent collection of Coleoptera which he has managed to form by his great passion for entomology and his liberality. PLUSIOTIS VICTORINA, Hope, Proc. Ent. Soc. 1840, p. 11. P. victorina: capite thoraceque profunde punctatis cupreo rufis; elytris fortiter punctatis, splendide viridi-aureis, lineis maculari-bus rufis, margine cupreo; infra cupreo-rufa, tarsis nigris, antennis fuscis. Length 1 inch 4 lines. In the collections of the British Museum, Jardin des Plantes, Mnizech, Salle, Bates, Candeze. I have three specimens of this magnificent species, which comes very close to the genus Chrysina from its large size and its general appearance. This is why I have placed this species the last of all; and for the same reason I began my list with P. resplendens, which is the species most closely allied to Pelidnota. They form natural links between these two genera. I found P. victorina for the first time on the 8th of May, 1857, on the road from Tepanzacualco to Istlan, about fifty miles from Oaxaca. They were devouring the young leaves of oak trees. |
