CEcETis OCHRACEA, C. — One example (abdomen wanting), whiter 

 tlian (not so ochraceous as) the southern form, but resembling what 

 appears to be the usual condition in Scotland. 



Plecteocnemia conspersa, C. — One ^, small, and veri/ dark. 



POLTCENTEOPUS ELAVO-MACXILATUS, Pict. ?. — One ? . 



Thus, small size and dark colour are the dominant features of 

 the Shetland TricJwptera, just as occurs in those most remarkable 

 Lepidopte^^a from the same quarter that have excited so much interest 

 with British Lepidopterists, and which are proving equally interesting 

 on tlie continent. 



Two $ examples of Sydroptila from the Island of Hoy are not 

 determinable.

ON THE SCOPELODES UNICOLOR OF WESTWOOD AND WALKER. 

 BY ARTHUR G. BUTLER, F.L.8., F.Z.S., &c. 



The genus Scopelodes (a group of Limacodid moths) was charac- 

 terized by Westwood on page 222 of the fifth volume of Duncan's 

 I" Naturalists' Library ;" the typical species, S. unicolor, being de- 

 scribed on the following page, and figured on plate xxviii (fig. 2). 



>S'. unicoJor, of TVestwood, is described as follows : — "The colour 

 of the entire moth is buff, the wings having a silky gloss, and the 

 palpi have a pale ring near the apex ; the back of the abdomen is 

 rather more fulvous, and marked with short black bands. It is an 

 {inhabitant of Java, and is in the collection of the Eev. F. "VY. Hope. 

 The expansion of the wings is two inches and three-quarters." 



It is perfectly clear that Walker never referred either to descrip- 

 tion or figure of this species ; even his reference, " Dune. Nat., xxxvii, 

 222," proves so much, since the volume is not quoted and the number 

 of the plate (which Walker evidently believed to be that of the 

 volume), is not quoted correctly : but it is also evident that, if the 

 description had been looked at, the locality given by Westwood, 

 " Java," would have had some weight in Walker's identification of 

 the species, and the figure (which, by the way, is only misleading, as 

 it is coloured utterly unlike any Scopelodes that ever existed, with a 

 combination of burnt-sienna and brick-red), might have made him un- 

 i willing to give the name S. palpalis to the common species of Java.
