84 LORD WALSINGHAM ON NEW TINETD.^. [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 7g 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 con- 

 dition 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 5 , of which he says : — " Alee posticse nigricanti- 

 cinerese, 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 Phila- 

 delphia' 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, ordinatellus,WR\k., 

 and secondly, multipunctetluSjClem. — 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 (erro- 

 neously) 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 

 redescriptiou of H. multipunctellus, Clem., in the Verb. z.-b. Ges. 

 Wien, xxiii. p. 228, where he writes : — " Post. S dilute cinereis albo 

 ciliatis, $ 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 H. 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-
