In addl- lion to the typ% the Museum possesses seven other specimens referable to this new species, all from Sarawak. This North Bornean form differs so greatly from P. rubi- cundu,% both as regards colom' and skull-characters, that it must be considered specifically distinct from the Southern species.

XXVI.--Deserlptions of new South-Amerlcan Arctiante. By the lion. WALTER ROTHSCHILD,Ph.D. IN ~ Novitates Zoologic~e,' vol. xvi. (1909)~ I described some 118 new species of Arctianze, and the present paper is a continuation of the same work. The bulk of the species were collected by S. M. Klages and the late G. R. Ockeuden.

1. Ammalo helops (Cram.). In vol. ill. of the 'Catalogue of Lepidoptera Phalmnae' Sir George tlampson has united under Ammalo helops(Cram.) the following:--A, helops (Cram.), A. fervldus, Walk., A. vlegapz/rrh % Walk., A. chrffsogaster, Walk., and A. impunctus~ Grote, to which he afterwards added trujillaria, Dogn. The latter is quite a distinct species, it nowremains for me to discuss the five names treated as synonyms by ,Sir George. The figure of (Jramer clearly shows an insect which has on the fore wing a large red patch in the cell and four or five other patches of red beyond it. The types of chrtjsogaster and megopyrrha are both without any such marks~ thus agreeing with Grote's impunctus. A. fervhtus is a similar insect~ but of an orange-rutbus colour all over except t}le usuaI yellow and b]ack banded abdomen, q_'hus we find two distinct types~ one with red patches o~l the disk and one without ; but it appears to be a fact that by far the

Downloaded by [McGill University Library] at 21:19 04 February 2015 larger number of specimens from Mexico and Central America have no patches, thereibre I have come to the conclusion that these ought to be regarded as a separate subspecies under the name of A. helops megapffrrh% Wlk.

XXVII.--Note on the Genus Smithia, Maltzan. By EDGAR A. SMITH, I.S.O. (Published by permission of the Trustees of the British Museum.) THE genus Smlth[a was founded b the late Baron [I. yon Maltzau ~ for a remarkable marineYshel| from tile Island of Goree belonging to the family Turrlteliidse. Its peculiarity consists in the whorls being uncoiled in corkscrew fashion. Other~'ise it agrees in the character both of the shell and operculum with Turrltella and Mesalia. Maltzau compared it with .Ejlisia, but that genus is said to have a paucispiral operculum~ whereas in Smithla it is concentric and multispiral. It has been pointed out by the late Dr. E. yon Martens 1" that the generic name Smithia had previously been employed in zoology by Edwards and Haime (1851)~ Saussure (1855), and Mabille (1879). The Museum having recently acquired a specimen of this curious shell, it has become necessary to invent a new generic
