Show 84 LORD WALSINGHAM ON NEW TINEID^E. [Feb. 17, of the fore wings, dusky. Fore wings bright purple, thickly and regularly sprinkled with bright golden metallic scales ; the cilia mixed purple and golden. Hind wings purple. Expanse 7^ millims. A small but distinct species, about the size of M. calthella. One specimen, taken in Southern Oregon in May 1872. I have a single specimen of another undescribed species from Northern Oregon, April 1872, but scarcely in sufficiently good condition to be determined with certainty. Head dusky greyish. The fore wings purple, dusted with thickly scattered yellowish and whitish scales, giving a slightly blotched appearance, and forming an ill-defined spot on the dorsal margin before the anal angle. The cilia are pale, and the hind wings very transparent cinereous. Expanse 9 millims. Apparently allied to the European M. unimaculella. I leave it to be named by any one who may be able to verify the description by obtaining a series of specimens in better condition. Genus HYPONOMEUTA, Zeller. Mr. Walker, in his ' Catalogue of Lepidoptera Heterocera in the British Museum,' part xxviii. p. 530, describes Hyponomeuta ordi-natellus S and $ , of which he says : - " Alae posticae nigricanti-cinereae, fimbria alba;" and in part xxx. p. 1016, he mentions Hyponomeuta "multipunctellus," Clem., and refers his H ordina-tellus to this species. Dr. Clemens described his H. multipunctella, in the ' Proceedings of the Academy of Natural Sciences of Philadelphia' for 1860, p. 8, as having the hind wings " blackish grey," but without mentioning the sex of his type. The single specimen placed by Mr.Walker under the two names-first, ordinatellu8,Wa\k., and secondly, multipunctellus, Clem.-has decidedly white hind wings, and is therefore evidently not one of those from which the original description was made, and which were said to have come from Canada. A reference to the Register shows that the specimen was " purchased from Mr. Dyson," in a miscellaneous collection of North-American insects. It is probably the one mentioned by Mr. Walker (erroneously) as having been " presented by Mr. Doubleday," since he only refers to one specimen as existing in the national collection, and no other can be found. If this specimen is a female (of which I am not at present absolutely convinced), it will agree with Prof. Zeller's redescription of II. multipunctellus, Clem., in the Verh. z.-b. Ges. Wien, xxiii. p. 228, where he writes : - " Post. 6* dilute cinereis albo ciliatis, 2 totis albis." Prof. Zeller points out that if Walker's original H. ordinatellus had the hind wings dark in both sexes, it cannot be the same species as II. multipunctella, Clem. There must, then, be two distinct species agreeing in all other particulars ; and this remains to be proved. But it seems more probable that Mr. Walker may have been mistaken as to the sex of one of his ori- |
