some new Species of exotic Coleopterous Insects. 7 1 



membranaceum, emarginatum, ciliatum. Palpi labiales bre- 



vissimi, 3-articulati, articulo basali minuto. Antennae in 



utroque sexu corporis longitudine, 11-articulatae, articulo 



basali reliquis crassiori, 2ndo minuto, 8 proximis in mare, 



postice longe flabellatis, striatis, ultimo longo, flabellum ter- 



minante ; in foemina vero simplicibus, 8vo, 9no, et lOmo, 



antice paullo productis, (fig. 2 h, caput et pronotum 5.) 



Thorax transversus spind laterali utrinque armatus. Elytra sub- 



depressa, sericeo-punctata, apicibus integris. Pedes mediocres, 



simplices. 



This genus is not only interesting on account of the beautiful 



structure of the antennae of the males, of which the genera Psyg- 



matocerus and P/uenicocerus, alone* in the vast tribes of the Lin- 



naean Cerambyces, offer any analogous instance, but also from the 



geographical situation which it occupies, being an inhabitant of 



New Holland, whereas the two genera above mentioned are from 



Brazil. In the structure of the mouth it approaches nearest to 



Anacolus. In some respects, however, it seems allied to Lamia, 



whilst the peculiar appearance of the very minutely punctured 



elytra most nearly resemble some of the Cerambyces and Stenocori. 



Sp. 1. Rhijpidocervs Australasice, Westvv. 



Obscure viridis punctatissimus, luteo-subsericeus, antennis mascu- 

 linis brunneis, fccmininis fulvis apicibus articulorum nigris, 

 pedibus brunneo-fulvis, femorum apicibus obscurioribus.

* Mr. Newman has recently described another longicorn genus with flabellate 

 antennas, also from New Holland, under the name of Petalodes laminosiis. — 

 Entomologist, p. 9. Still more recently (June, 1842) I have seen in the col- 

 lection of M. Reich, at Paris, another flabellated species from New Holland, 

 which may be thus concisely characterized : — 



Piesarthrius? Hope, Proc. Zool. Soc. 1840, p. 55. 

 P. Reichii, Westw. P. capite et pronoto obscure fuscis, varioloso-punclatis et 

 fulvo-pilosis ; elytris piceo-rufis, macula magna disroidali communi ante medium, 

 antice bifida, strigisqueduabus posticis luteis ; pronoto subquadrato ; antennis fla- 

 bellatis, articuHs longitudine crescentibus ; elytris apice rotundatis et ad sutura 

 breviter aculeatis.
