broad, entire : the superior pair acute at the apex, the lines sliglitly 

 sketched : inferior pair with scarcely distinct lines, the uervures not 

 punctated : neuration of Scotosia. 



I establish this new genus on a small New Zealand species, which 

 is not larger than an Eupitkecia, but which has the aspect of a Scotosia, 

 although the pectinated antenna) and entire wings distinguish it at first 

 sight.

Size of Eii/pitUecia impurata. Superior wings greyish-white, with an olivaceous 

 tinge ; three parallel sinuated and toothed blackish bands, rather well marked as 

 far as the middle of the wing, but becoming afterwards indistinct ; the third is the 

 best marked and the most sinuated ; the sub-terminal is only indicated by slight 

 groups of atoms ; the cellular dot very small ; fringe concolorous, preceded by in- 

 distinct geminated dots : inferior wings paler and more whitish, above with only 

 traces of gi'eyish lines, but beneath there are two sinuated and toothed median 

 lines, and a cellular dot, rather well marked, on a pale, sometimes white, ground 

 colour, while this side of the superior wings is suffused with blackish-grey. Body 

 concolorous ; abdomen with ill-defined, blackish, geminated dots.

 them ; it resembles the S .

NOTES ON THE GENUS ACIDALIA, WITH DESCRIPTION OF THE LARVA 

 OF A. HOLOSERICATA* &c. 



BY REV. J. HELLINS, M.A. 



To Mr. A. E. Hudd, of Clifton, I am indebted for the opportunity 

 of watching the earlier stages of another Acidalia, viz., holosericata ; 

 and his kindness is the more thankworthy, in that he supplied me with 

 eggs three years in succession, until I could succeed in breeding the 

 moths. "Whilst engaged with this species, I took in hand some others, 

 hisetata, scutulata, and interjectaria (as we must now call what used to 

 pass in this locality for osseata), and made notes of their various stages ; 

 also imitaria and immutata, but having described these before, I now go 

 no further with them than the egg. 



• It does not please one's sense of the fitness of things to see the two forms of the same word, 

 Holosericata and S^xxbsericeata, standing so close to one another in our lists, but I have not thought 

 myself at liberty to insert the e in the former after receiving the following information from Mr. 

 Doubleday: — "I suppose Holosericata was the name given to this species by Duponchel, but I think 

 " it was probably written so in mistake for Holosericeata ; the synonymes stand thus in Dr. Staudinger's 

 " Catalogue : ' ^'o. 78, Holosericata Dup. iv., p. 109, pi. 59, 7. 



Gn. I. 468, Holosericearia H. S. 80—81.' 

 " This is all the information I can give you on the subject."— J. H.
